Autism Spectrum Disorder and Early Psychosis: a narrative review from a neurodevelopmental perspective

Autism Spectrum Disorder (ASD), characterized by socio-communicative abnormalities and restricted, repetitive, and stereotyped behaviors, is part of Neurodevelopmental Disorders (NDDs), a diagnostic category distinctly in accordance with the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition, (DSM-5), clearly separated from Schizophrenia Spectrum Disorder (SSD) (schizophrenia, schizophreniform disorder, schizoaffective disorder, schizotypal personality disorder). Over the last four decades, this clear distinction is gradually being replaced, describing ASD and SSD as two heterogeneous conditions but with neurodevelopmental origins and overlaps. Referring to the proposal of a neurodevelopmental continuum model, the current research's aim is to provide an update of the knowledge to date on the course of clinical symptoms and their overlaps among ASD and SSD. A narrative review of the literature published between January 2010 and June 2023 was conducted. Five studies were included. All studies show a global impairment in both conditions. Two studies show a focus on neurodevelopmental perspective in ASD and SSD. Only one study of these adopts a longitudinal prospective in terms of prognostic markers among ASD and SSD. Three studies underline the overlap between ASD and SSD in terms of negative, disorganized and positive symptomatology. To date, there is a gap in the current scientific literature focused on ASD-SSD course of clinical symptoms and their overlaps from a neurodevelopmental perspective. Future longitudinal studies to identify risk markers and tailored treatments are needed.

Clinical features and comorbidity in very early-onset schizophrenia: a systematic review

Background

Very early-onset schizophrenia (VEOS) is a form of schizophrenia that manifests before the age of 13 years and is characterized by the presence of positive, negative, and disorganized symptoms. The condition is exceptionally rare and, to date, limited studies have been conducted, resulting in incomplete information about its clinical features.

Methods

The present study involves a systematic review of the existing literature regarding the clinical features and comorbidities of VEOS.

Results

The first search retrieved 384 studies. Of these, 366 were removed following the application of exclusion criteria, resulting in 18 studies for the final set.

Conclusion

The results highlight that VEOS shares similarities with early-onset and adult-onset schizophrenia but also exhibits distinct and recognizable characteristics, including a more severe clinical profile (particularly in females), increased visual hallucinations, and high comorbidities with neurodevelopmental disorders. These findings may support clinicians in formulating early diagnoses and developing effective treatment strategies for pediatric and adolescent patients with psychosis.

Psychiatric Disorders in Children and Adolescents: Clinical Issue and Strategies for Intervention

Mental health plays a crucial role in an individual's overall well-being, and it is widely recognized that many adult mental health disorders originate during childhood and adolescence. It is imperative to promptly recognize signs of psychological distress and clinically significant symptoms that can affect an individual's functioning from an early age. The growing prevalence of psychiatric disorders in children and adolescents indeed highlights the significance of identifying both risk and protective factors. Finally, a personalized and integrated treatment approach is essential to prevent the chronicity and pervasiveness of symptoms.

Psychiatric Hospitalization for Psychopathological Disorders and Self-Injurious Behaviors in Italian Children and Adolescents during COVID-19

The evidence shows that the COVID-19 pandemic dramatically increased the number of urgent psychiatric consultations for children and adolescents in hospital emergency departments (EDs). However, what needs to be further investigated are the characteristics of psychiatric hospitalization in children and adolescents admitted to the Child and Adolescent Neuropsychiatry Unit wards in EDs. Specifically, this retrospective study aimed to examine changes in (i) the number of inpatients and (ii) the distribution of psychopathological disorders and self-injurious behaviors in our Child and Adolescent Neuropsychiatry Unit ward during the COVID-19 lockdown in Italy (March-June 2020; October 2020-January 2021) compared with the same months of previous years. We found a significantly lower number of inpatients during the first four quarantine months than the first four reference months and a higher number of inpatients during the second four quarantine months than the second four reference months. Additionally, we found an increased frequency of mood disorders, non-suicidal self-injurious behavior, and suicidal ideation during the COVID-19 lockdown compared to the reference periods. Our findings underline the need to develop psychological healthcare services for future emergency periods in order to identify and treat psychological distress in children and adolescents early, reducing the risk of psychiatric hospitalization.

Dopaminergic signalling and behavioural alterations by Comt-Dtnbp1 genetic interaction and their clinical relevance

BACKGROUND AND PURPOSE

Cognitive and motor functions are modulated by dopaminergic signalling, which is shaped by several genetic factors. The biological effects of single genetic variants might differ depending on epistatic interactions that can be functionally multi-directional and non-linear.

EXPERIMENTAL APPROACH

We performed behavioural and neurochemical assessments in genetically modified mice and behavioural assessments and genetic screening in human patients with 22q11.2 deletion syndrome (22q11.2DS).

KEY RESULTS

Here, we confirm a genetic interaction between the Comt (catechol-O-methyltransferase, human orthologue: COMT) and Dtnbp1 (dystrobrevin binding protein 1, alias dysbindin, human orthologue: DTNBP1) genes that modulate cortical and striatal dopaminergic signalling in a manner not predictable by the effects of each single gene. In mice, Comt-by-Dtnbp1 concomitant reduction leads to a hypoactive mesocortical and a hyperactive mesostriatal dopamine pathway, associated with specific cognitive abnormalities. Like mice, in subjects with the 22q11.2DS (characterized by COMT hemideletion and dopamine alterations), COMT-by-DTNBP1 concomitant reduction was associated with analogous cognitive disturbances. We then developed an easy and inexpensive colourimetric kit for the genetic screening of common COMT and DTNBP1 functional genetic variants for clinical application.

CONCLUSIONS AND IMPLICATIONS

These findings illustrate an epistatic interaction of two dopamine-related genes and their functional effects, supporting the need to address genetic interaction mechanisms at the base of complex behavioural traits.

Autism spectrum disorder, very-early onset schizophrenia, and child disintegrative disorder: the challenge of diagnosis. A case-report study

Background

Autism spectrum disorder (ASD) in the Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM-5) contains several disorders previously present as distinct diagnoses in the DSM Revised Fourth Edition (DSM-IV-TR). These include child disintegrative disorder (CDD). The latter presents typical features, such as a late regression of developmental acquisitions. However, it also shows symptoms similar to ASD, and psychotic symptoms, such as very-early onset schizophrenia (VEOS), are described in the literature.

Case report

In this case report we deepen the case of P., a child who presents a late regression, at 7 years old, associated with psychotic symptoms in the absence of organic alterations. The child was treated with antipsychotic drug therapy and cognitive behavioral therapy. P. was diagnosed with ASD with acute and late regression associated with psychotic symptoms. During the follow-up, there was a gradual improvement in the clinical conditions. Improvements were possible due to therapeutic intervention (pharmacological and psychotherapeutic) and/or the natural course of the disorder.

Conclusion

The diagnostic difficulty of this case reflects a clinical complexity in which it is not easy to distinguish between neurodevelopmental and psychiatric aspects. Clinical cases such as that of P. emphasize the theme of the neurodevelopment continuum model in which neurodevelopmental and psychiatric disturbances can be considered within a pattern of pathological continuity.

Chromatin regulators in the TBX1 network confer risk for conotruncal heart defects in 22q11.2DS

Congenital heart disease (CHD) affecting the conotruncal region of the heart, occurs in 40-50% of patients with 22q11.2 deletion syndrome (22q11.2DS). This syndrome is a rare disorder with relative genetic homogeneity that can facilitate identification of genetic modifiers. Haploinsufficiency of TBX1, encoding a T-box transcription factor, is one of the main genes responsible for the etiology of the syndrome. We suggest that genetic modifiers of conotruncal defects in patients with 22q11.2DS may be in the TBX1 gene network. To identify genetic modifiers, we analyzed rare, predicted damaging variants in whole genome sequence of 456 cases with conotruncal defects and 537 controls, with 22q11.2DS. We then performed gene set approaches and identified chromatin regulatory genes as modifiers. Chromatin genes with recurrent damaging variants include EP400, KAT6A, KMT2C, KMT2D, NSD1, CHD7 and PHF21A. In total, we identified 37 chromatin regulatory genes, that may increase risk for conotruncal heart defects in 8.5% of 22q11.2DS cases. Many of these genes were identified as risk factors for sporadic CHD in the general population. These genes are co-expressed in cardiac progenitor cells with TBX1, suggesting that they may be in the same genetic network. The genes KAT6A, KMT2C, CHD7 and EZH2, have been previously shown to genetically interact with TBX1 in mouse models. Our findings indicate that disturbance of chromatin regulatory genes impact the TBX1 gene network serving as genetic modifiers of 22q11.2DS and sporadic CHD, suggesting that there are some shared mechanisms involving the TBX1 gene network in the etiology of CHD.

Phenomenological Considerations of the World of the Obsessive Patient

Despite significant scientific advances in research on obsessive-compulsive disorder (OCD), the psychological and behavioral symptoms of this pathological condition remain hard to understand, until they seem paradoxical. The present work seeks to consider the significance and potential contribution of a phenomenological reading of OCD and how phenomenalism has influenced some cognitive models of this disorder. Transcendental phenomenology is a philosophical approach that attaches primary importance to intuitive experience and considers all phenomena intrinsically associated with the subject's inner world. Thus, the subject's intuition is considered the starting point for understanding their essential experience. This approach has had a profound influence on modern cognitive sciences. Among current cognitive models, post-rationalist cognitivism and cognitive neuropsychological psychotherapy seem most effective in capturing the world experiences of OCD patients. Both apply a phenomenological approach to identify these experiences, which are typically characterized by hyper-reflexivity, at the expense of 'natural evidence.' The models have found that OCD patients experience the world emotionally as a sterile set of rules, and this experience determines their suffering.

A network analysis of anxiety, depressive, and psychotic symptoms and functioning in children and adolescents at clinical high risk for psychosis

Objective

Youths at clinical high risk for psychosis (CHR-P) are characterized by a high prevalence of anxiety and depressive disorders. The present study aimed at developing and analyzing a network structure of CHR-P symptom domains (i.e., positive, negative, disorganization, and general subclinical psychotic symptoms), depressive and anxiety symptoms, and general functioning.

Methods

Network analysis was applied to data on 111 CHR-P children and adolescents (M age = 14.1), who were assessed using the Structured Interview for Prodromal Syndromes, the Children's Depression Inventory, the Children's Global Assessment Scale, and the Multidimensional Anxiety Scale for Children.

Results

In the network, negative and disorganization symptoms showed the strongest association (r = 0.71), and depressive and anxiety symptoms showed dense within-domain connections, with a main bridging role played by physical symptoms of anxiety. The positive symptom cluster was not associated with any other node. The network stability coefficient (CS) was slightly below 0.25, and observed correlations observed ranged from 0.35 to 0.71.

Conclusion

The lack of association between subclinical positive symptoms and other network variables confirmed the independent nature of subclinical positive symptoms from comorbid symptoms, which were found to play a central role in the analyzed network. Complex interventions should be developed to target positive and comorbid symptoms, prioritizing those with the most significant impact on functioning and the most relevance for the young individual, through a shared decision-making process. Importantly, the results suggest that negative and disorganization symptoms, as well as depressive and anxiety symptoms, may be targeted simultaneously.

Obsessive Compulsive “Paper Handling”: A Potential Distinctive Behavior in Children and Adolescents with KBG Syndrome

KBG syndrome (KBGS; OMIM #148050) is a rare disease characterized by short stature, facial dysmorphism, macrodontia of the upper central incisors, skeletal anomalies, and neurodevelopmental disorder/intellectual disability. It is caused by a heterozygous variant or 16q24.3 microdeletions of the ANKRD11 gene (OMIM #611192), which plays a primary role in neuronal development. KBGS traits are variable, and mild expressions of the phenotype may complicate diagnosis. The present work aims at improving the characterization of KBGS in order to facilitate its recognition. A psychopathological evaluation of 17 subjects affected by KBGS found that 10 patients exhibited peculiar behavior related to “paper handling”. These children and adolescents performed repetitive activities with paper, reminiscent of the hoarding and ordering behaviors characteristic of obsessive compulsive disorder. Their activities were time consuming and carried out in solitary, and forced interruption could generate intense emotional reactions. Paper handling may thus be understood as a potential distinct KBGS symptom akin to an obsessive compulsive symptom. Further research is needed to verify this claim.

Hand Washing: When Ritual Behavior Protects! Obsessive-Compulsive Symptoms in Young People during the COVID-19 Pandemic: A Narrative Review

The Coronavirus Disease 2019 (COVID-19) pandemic had a profound impact on the lifestyles and mental health of young people. It has been hypothesized that the focus on hygiene and the fear of contamination/infection during the pandemic may have exacerbated obsessive–compulsive (OC) symptoms in this population. OC symptoms are widespread in the general population, with varying degrees of intensity. At their most extreme, they manifest in obsessive–compulsive disorder (OCD), which is characterized by obsessive thoughts and compulsive behaviors. The present narrative review aimed at evaluating the relationship between the COVID-19 pandemic and OCD and OC symptoms in young people, especially children and adolescents with and without OCD, focusing on vulnerability and risk factors and the impact of lockdown measures. Of the six studies identified, four examined clinical samples diagnosed with OCD and two looked at community-based adolescent samples. Five of the six studies found that OC symptoms increased during the pandemic. Additionally, vulnerability to anxiety may constitute a risk condition and the lockdown measures and personal stressful life events can constitute potential triggers of OC symptoms, while ongoing treatment for OCD had a protective effect. The results suggest that, during the COVID-19 pandemic, obsessive and compulsive behavior (e.g., hand washing) in young people at the greatest risk should be monitored, and the intervention of mental health services should be maintained. More research is needed in this area.

Developmental Psychopathology in the COVID-19 period. COVID-19 Pandemic Impact on Children and Adolescents' Mental Health

Over the past year, the novel coronavirus (COVID-19) pandemic has forced many world countries, including Italy, to take strict restrictive measures as lockdown and social distancing. Children and adolescents exposed to the COVID-19 pandemic and social distancing would appear to be at greater risk of developing psychiatric disorders. In the last year, the Child and Adolescence Neuropsychiatry service at the Children's Hospital Bambino Gesù in Rome has recorded a significant increase in cases of mood disorders, self-injurious behaviors and suicidal ideation. These data underlined the need to define tailor-made intervention strategies for children and adolescents during this time of social and health emergency.

Psychoeducation focused on family accommodation: a practical intervention for parents of children and adolescents with obsessive-compulsive disorder

Obsessive-compulsive disorder (OCD) is a neuropsychiatric disorder that is frequently diagnosed in children and adolescents. In pediatric OCD, family plays an important role in the development and maintenance of the disease. In this relationship, both genetic and behavioral factors, such as parental modeling and family accommodation, are significant. Parental modeling concerns the daily enactment of dysfunctional behavioral patterns by a parent with OCD, which may influence children. Family accommodation, in contrast, describes the direct participation of parents in their child's compulsive rituals, by modifying daily routines or by facilitating avoidance of OCD triggers, to decrease the child's distress and time spent executing compulsions. Approximately 80-90% of the relatives of OCD patients actively participate in patients' rituals. The literature demonstrates that a high level of family accommodation is associated with OCD symptom severity, reduced response to cognitive-behavioral treatment (CBT), and a higher risk of therapy dropout.Despite this, no studies have aimed at delineating practical guidance for psychotherapists to support parents in reducing family accommodation.The main aim of this paper is to propose a psychoeducation intervention focused on cognitive-behavioral strategies to help families to manage their child's OCD behaviors without enacting dysfunctional family accommodation behaviors in order to support their child's successful therapy.

Genetic contributors to risk of schizophrenia in the presence of a 22q11.2 deletion

Schizophrenia occurs in about one in four individuals with 22q11.2 deletion syndrome (22q11.2DS). The aim of this International Brain and Behavior 22q11.2DS Consortium (IBBC) study was to identify genetic factors that contribute to schizophrenia, in addition to the ~20-fold increased risk conveyed by the 22q11.2 deletion. Using whole-genome sequencing data from 519 unrelated individuals with 22q11.2DS, we conducted genome-wide comparisons of common and rare variants between those with schizophrenia and those with no psychotic disorder at age ≥25 years. Available microarray data enabled direct comparison of polygenic risk for schizophrenia between 22q11.2DS and independent population samples with no 22q11.2 deletion, with and without schizophrenia (total n = 35,182). Polygenic risk for schizophrenia within 22q11.2DS was significantly greater for those with schizophrenia (padj = 6.73 × 10-6). Novel reciprocal case-control comparisons between the 22q11.2DS and population-based cohorts showed that polygenic risk score was significantly greater in individuals with psychotic illness, regardless of the presence of the 22q11.2 deletion. Within the 22q11.2DS cohort, results of gene-set analyses showed some support for rare variants affecting synaptic genes. No common or rare variants within the 22q11.2 deletion region were significantly associated with schizophrenia. These findings suggest that in addition to the deletion conferring a greatly increased risk to schizophrenia, the risk is higher when the 22q11.2 deletion and common polygenic risk factors that contribute to schizophrenia in the general population are both present.

Coping With Adolescents Affected by Anorexia Nervosa: The Role of Parental Personality Traits

Introduction

Anorexia nervosa (AN) promotes psychological distress in caregivers who adopt different coping strategies. Dysfunctional caregiving styles exacerbate further distress in the patient promoting the maintenance of the illness. We aimed to assess the possible contribution of personality traits of caregivers to the adoption of different coping strategies to deal with the affected relative.

Methods

About 87 adolescents with AN were recruited. Their parents completed the Family Coping Questionnaire for Eating Disorders (FCQ-EDs) and the Temperament and Character Inventory-Revised (TCI-R). Differences between mothers and fathers were assessed through the independent sample t-test. Multivariate regression analyses were run to assess if personality traits, the occurrence of psychiatry conditions in the parents, the marital status, and the duration of the illness predicted parental coping strategies.

Results

The group of mothers showed higher levels of avoidance and seeking for information coping strategies than the sample of fathers. Lower illness duration predicted higher collusion with the illness in both parents. Harm avoidance, cooperativeness, and self-directedness positively predicted parental coercion, collusion, and seeking for information strategies with some differences between mothers and fathers.

Discussion

Illness duration and personality traits of parents affect the type of parental coping strategies developed to face AN in adolescents. These variables should be considered in the assessment of families of adolescents with AN and may be addressed to promote more fine-tuned clinical interventions for caregivers.

Neurodevelopmental Trajectories and Clinical Profiles in a Sample of Children and Adolescents With Early- and Very-Early-Onset Schizophrenia

Schizophrenia before the age of 18 years is usually divided into two categories. Early-onset schizophrenia (EOS) presents between the ages of 13 and 17 years, whereas very-early-onset schizophrenia (VEOS) presents at or before the age of 12 years. Previous studies have found that neurodevelopmental difficulties in social, motor, and linguistic domains are commonly observed in VEOS/EOS patients. Recent research has also shown a high prevalence of neurodevelopmental disorders (e.g., intellectual disability, communication disorders, autism spectrum disorder, neurodevelopmental motor disorders) in VEOS/EOS patients, indicating genetic overlap between these conditions. These findings lend support to the neurodevelopmental continuum model, which holds that childhood neurodevelopmental disorders and difficulties and psychiatric disorders (e.g., schizophrenia) fall on an etiological and neurodevelopmental continuum, and should not be considered discrete entities. Based on this literature, in this study we focused on the overlap between neurodevelopmental disorders and schizophrenia investigating, in a large sample (N = 230) of VEOS/EOS children and adolescents, the clinical differences, at the onset of psychosis, between VEOS/EOS with neurodevelopmental disorder or neurodevelopmental difficulties and VEOS/EOS with no diagnosed neurodevelopmental disorder or neurodevelopmental difficulties. The findings showed that, in children and adolescents with a neurodevelopmental disorder or neurodevelopmental difficulties, psychosis onset occurred at an earlier age, was associated with more severe functional impairment (e.g., global, social, role), and was characterized by positive symptoms (e.g., grandiose ideas, perceptual abnormalities, disorganized communication) and disorganized symptoms (e.g., odd behavior or appearance, bizarre thinking). Instead, in children and adolescents without a neurodevelopmental disorder or neurodevelopmental difficulties, psychosis onset was mainly characterized by negative symptomatology (e.g., social anhedonia, avolition, expression of emotion, experience of emotions and self, ideational richness). Given these differences, the presence of a neurodevelopmental disorder or neurodevelopmental difficulties should be carefully investigated and integrated early into the assessment and treatment plan for VEOS/EOS patients.

Clinical significance of family accommodation and parental psychological distress in a sample of children and adolescents with obsessive-compulsive disorder aged 8-17 years old

BACKGROUND

Family Accommodation (FA) refers to the involvement of family members (especially parents) in the compulsive behaviors of children and adolescents with Obsessive-Compulsive Disorder (e.g. modifying family routines or facilitating avoidance of obsessive-compulsive triggers). Many studies have examined the high prevalence of FA in this clinical population; however, less is known about its clinical significance and relationship to the individual psychological distress of parents. In our study, we investigated the clinical significance of FA examining its relationship with obsessive-compulsive symptomatology, functioning, anxiety and depressive symptoms in a clinical sample (n = 51) of children and adolescents with Obsessive-Compulsive Disorder (OCD) aged 8-17 years old and their parents, included to examine their individual psychological distress.

METHODS

The sample was divided into two groups: the High Accommodation group (n = 36) and the Low Accommodation group (n = 15).

RESULTS

Results demonstrated that children and adolescents in the OCD High Accommodation group reported major functional impairment in global (p = .001313), social (p = .000334) and role (p = .000334) domains, and higher depressive symptoms than the Low Accommodation group. Both fathers and mothers from the High Accommodation group reported a higher level of individual psychological distress compared to mothers and fathers from the Low Accommodation group (p = .040365).

CONCLUSIONS

The findings of this study show that FA is common in children and adolescents with OCD and it could cause not only an impairment of the patient's global, social and role functioning but also a high level of individual psychological distress in the single parent. The presence of FA should therefore be carefully investigated and considered in planning assessment and treatment of OCD in children and adolescents.

An attachment perspective on the risk for psychosis: Clinical correlates and the predictive value of attachment patterns and mentalization

BACKGROUND

In a longitudinal design, the present study examined: (a) the nature of attachment patterns and reflective functioning (RF) in individuals at ultra-high risk for psychosis (UHR); (b) the association between RF and subclinical psychotic symtoms; and (c) the psychosis-predictive value of attachment patterns, RF, and the interaction between these factors.

METHOD

The sample comprised 57 UHR subjects and 53 clinical controls (non-UHR). UHR subjects were followed over a mean period of 14 months (SD = 2.7; range 11-19), during which time 11.5% developed psychosis. Attachment patterns and RF were measured. Hierarchical logistic regression was used to examine the predictive value of variables in the transition to psychosis.

RESULTS

At baseline, significant differences were found between groups in secure attachment patterns and RF. RF was negatively associated with the attenuated psychotic symptoms described by the Unusual Thought Content/Delusional Ideas, Suspiciousness/Persecutory Ideas, and Disorganized Communication subscales. Moreover, poor mentalization was related to an increased likelihood of developing a psychotic disorder (OR = 0.427, 95% CI [0.188, 0.970]); conversely, no predictive effects of the attachment variables and their interaction with RF on the transition to psychosis were found. Notably, an optimal threshold value of RF = 1.25 was found to distinguish UHR subjects who made the transition to psychosis from those who did not develop this pathology.

CONCLUSION

The results suggest that aberrant mentalizing patterns can predict the development of psychosis. Clinical implications of these results for the development of preventive treatments are discussed.

Clinical profile, conversion rate, and suicidal thinking and behaviour in children and adolescents at ultra-high risk for psychosis: a theoretical perspective

Over the past years there has been substantial growing interest in the prodromes of psychosis to identify individuals at risk for psychosis prior to their first psychotic episode. Researchers have proposed criteria to detect young adults at Ultra-High Risk (UHR) for psychosis, and these criteria have also been applied to children and adolescents, though few clinical studies have examined this population. This theoretical perspective presents some of the crucial issues in the assessment and treatment of UHR children and adolescents: the presence of a specific clinical profile (i.e., different to that of healthy controls and UHR young adults), the predictive value of UHR criteria, and the presence and clinical significance of suicidal thinking and behaviour. In UHR children and adolescents, like UHR young adults, the presence of Attenuated Psychotic Symptoms (APS) is the most frequently reported inclusion criterion at baseline, with a prevalence of approximately 89–100%. In addition, there are frequently non-psychotic comorbid diagnoses of depressive and anxiety disorders. In contrast to the UHR adult population, UHR children and adolescents demonstrate a lower conversion rate to frank psychosis, most likely due to their high rate of APS. Finally, UHR adolescents report a high prevalence of suicidal ideation and self-injurious behaviour (67.5%), as well as a significantly greater frequency of attempted suicide, relative to adolescents with frank psychosis. On this basis, UHR children and adolescents report a clinical complexity that should be carefully monitored and considered for specific and targeted therapeutic interventions to be planned and developed.

Complete Sequence of the 22q11.2 Allele in 1,053 Subjects with 22q11.2 Deletion Syndrome Reveals Modifiers of Conotruncal Heart Defects

The 22q11.2 deletion syndrome (22q11.2DS) results from non-allelic homologous recombination between low-copy repeats termed LCR22. About 60%-70% of individuals with the typical 3 megabase (Mb) deletion from LCR22A-D have congenital heart disease, mostly of the conotruncal type (CTD), whereas others have normal cardiac anatomy. In this study, we tested whether variants in the hemizygous LCR22A-D region are associated with risk for CTDs on the basis of the sequence of the 22q11.2 region from 1,053 22q11.2DS individuals. We found a significant association (FDR p < 0.05) of the CTD subset with 62 common variants in a single linkage disequilibrium (LD) block in a 350 kb interval harboring CRKL. A total of 45 of the 62 variants were associated with increased risk for CTDs (odds ratio [OR) ranges: 1.64-4.75). Associations of four variants were replicated in a meta-analysis of three genome-wide association studies of CTDs in affected individuals without 22q11.2DS. One of the replicated variants, rs178252, is located in an open chromatin region and resides in the double-elite enhancer, GH22J020947, that is predicted to regulate CRKL (CRK-like proto-oncogene, cytoplasmic adaptor) expression. Approximately 23% of patients with nested LCR22C-D deletions have CTDs, and inactivation of Crkl in mice causes CTDs, thus implicating this gene as a modifier. Rs178252 and rs6004160 are expression quantitative trait loci (eQTLs) of CRKL. Furthermore, set-based tests identified an enhancer that is predicted to target CRKL and is significantly associated with CTD risk (GH22J020946, sequence kernal association test (SKAT) p = 7.21 × 10-5) in the 22q11.2DS cohort. These findings suggest that variance in CTD penetrance in the 22q11.2DS population can be explained in part by variants affecting CRKL expression.

Personality Traits and Disorders in Adolescents at Clinical High Risk for Psychosis: Toward a Clinically Meaningful Diagnosis

Aims: Recent meta-analytic data show that approximately 40% of individuals at clinical high risk for psychosis (CHR) receive at least one personality disorder (PD) diagnosis. Personality pathology could significantly influence CHR patients' prognosis and response to treatment. We aimed at exploring the PD traits of CHR adolescents, in order to outline a prototypic description of their most frequently observed personality characteristics. Methods: One hundred and twenty-three psychiatrists and psychologists used a Q-sort procedure [i.e., the Shedler-Westen Assessment Procedure-200 for Adolescents (SWAP-200-A)] to assess personality traits and disorders in 58 (30 male; mean age = 16 years, range = 13-19 years) CHR adolescents and two gender- and age-matched samples, respectively, with (n = 60) and without PDs (n = 59). Results: Differences between the CHR, PD, and clinical groups showed that CHR adolescents had pervasive and more clinically relevant schizoid, schizotypal, borderline, and avoidant traits, as well as poorer adaptive functioning. Moreover, by collecting the highest mean SWAP-200-A items, we empirically outlined a prototypic description of CHR youths, comprised of avoidance of social relationships; suspiciousness; obsessional thoughts; lack of psychological insight; dysphoric and overwhelming feelings of anxiety and depression; odd and anomalous reasoning processes or perceptual experiences; symptoms of depersonalization and derealization; and negative symptoms of avolition, abulia, blunted affects, and impaired role functioning. Conclusions: The results suggest that avoidant interpersonal strategies, impaired mentalization, and difficulties in emotional regulation could become important targets for psychosocial interventions with CHR adolescent populations.

22q11 microdeletion syndrome and ultra-high risk for psychosis: The role of neurological soft signs as an independent marker of vulnerability for psychosis

AIM

22q11 microdeletion syndrome has an increased risk for psychosis, similar to subjects at ultra-high risk for psychosis. Neurological soft signs are considered an endophenotype of psychotic disorders and a marker of vulnerability to Schizophrenia, consisting of overflow movements, dysrhythmia and speed of timed activities. To date, there are no studies that have evaluated the presence of the neurological soft signs in subjects with 22q11 microdeletion syndrome and there are a few studies that have analysed this issue in subjects at ultra-high risk.

METHODS

We sought to measure neurological soft signs in these two conditions, compared to healthy controls and to analyse the possible correlation between neurological soft signs and positive/negative symptoms both in 22q11 microdeletion syndrome and ultra-high-risk groups. 54 drug-naive patients (29 with 22q11 microdeletion syndrome and 25 at ultra-high risk for psychosis) and 25 healthy controls were evaluated for neurological soft signs.

RESULTS

Both clinical groups showed a greater number of neurological soft signs compared to healthy control, although the two clinical groups did not differ for the number of neurological soft signs. Positive correlation between speed of timed activities and negative symptoms was found in subjects at ultra-high risk.

CONCLUSION

Neurological soft signs could represent a marker of atypical neurodevelopment in the two populations examined. Since we did not found a strong correlation between neurological soft signs and positive/negative symptoms, we suggest that neurological soft signs could be indicators of vulnerability to psychosis independent from the psychopathology.

Peer Victimization and Onset of Social Anxiety Disorder in Children and Adolescents

Background: In the literature, several studies have proposed that children and adolescents with social anxiety had experienced previously victimization from peers and siblings. The aim of this review was to contribute to the updating of recent findings about the relationship between peer victimization and onset of social anxiety in children and adolescents. Methods: A selective review of literature published between 2011 and 2018 on Social Anxiety Disorder in children and adolescents that experienced peer victimization during childhood and adolescence. Results: Seventeen studies are included. All studies showed that peer victimization is positively correlated to the presence of social anxiety. Moreover, the perpetration of peer victimization may contribute to the maintenance and the exacerbation of social anxiety symptoms. Conclusions: In children and adolescents with Social Anxiety Disorder, it is necessary to evaluate firstly the presence of peer victimization experiences. Subsequently, therapeutics programs targeted to elaborate these experiences and to reduce the anticipatory anxiety and the avoidance that characterized these children and adolescents can be proposed.

Neurocognitive profile and onset of psychosis symptoms in children, adolescents and young adults with 22q11 deletion syndrome: A longitudinal study

BACKGROUND

The neurobehavioral phenotype of 22q11.2 deletion syndrome (22q11DS) includes cognitive dysfunction and high rates of psychotic symptoms and schizophrenia. Existing research has mainly considered changes in IQ, especially its decline, as a psychosis predictor. The aim of this study was to investigate, in a longitudinal perspective, the relationship between neuropsychological abilities (not only IQ but also executive functioning, language and visual-motor integration abilities) and onset of psychotic symptoms in a sample of children, adolescents and young adults with 22q11DS. In addition, the role of comorbid psychiatric disorders at baseline was taken into account.

METHODS

75 participants with 22q11DS, aged between 6 and 27 years at baseline, were included. Eighteen of the 75 participants had developed psychosis at the one year follow-up (onset psychosis-OP) and constituted the first group; 57 participants who had not developed a psychosis at the one year follow-up (without onset psychosis-WOP) constituted the second group.

RESULTS

At baseline, group OP showed lower IQ (both full scale and verbal and performance scale) and more perseverative errors as well as a reduced number of correct categories on the Wisconsin Card Sorting Test (WCST) compared to group WOP. In addition, at baseline, group OP showed a higher frequency of depressive disorders than group WOP.

CONCLUSION

Even if with caution, results suggest neuropsychological deficits and depressive symptoms should be considered and monitored as possible clinical signs for the onset of psychosis in children, adolescents and young adults with 22q11DS.

Prevalence, course and psychosis-predictive value of negative symptoms in 22q11.2 deletion syndrome

BACKGROUND

The 22q11.2 deletion syndrome (22q11DS) is one of the highest known risk factors for schizophrenia and recent findings have highlighted the clinical relevance of ultra-high risk (UHR) criteria in this population. However, studies in other at-risk populations have shown that the presence of negative symptoms (NS) is also of clinical relevance in predicting transition to psychosis. The present study examined in detail the presence and course of NS in 22q11DS, as well as their value in predicting transition to psychosis.

METHODS

A total of 111 participants aged between 8 and 33 years were assessed with the Structured Interview for Psychosis-Risk Syndromes (SIPS). A follow-up assessment was available for 89 individuals.

RESULTS

Core NS of at least moderate severity were present in 50.5% of the sample and were more severe in individuals meeting UHR criteria. They predominantly remained stable over time and their emergence between baseline and follow-up assessment was associated with significant functional decline. Some NS were significant predictors of conversion to psychosis and the emergence/persistence of psychosis risk.

CONCLUSIONS

Altogether, these findings highlight that NS are core manifestations of psychosis in individuals with 22q11DS that strongly impact global functioning. The presence of NS should be a primary target of early therapeutic intervention in this population.

Attention deficit hyperactivity disorder symptoms as antecedents of later psychotic outcomes in 22q11.2 deletion syndrome

Individuals with 22q11.2 Deletion Syndrome (22q11.2DS) are at substantially heightened risk for psychosis. Thus, prevention and early intervention strategies that target the antecedents of psychosis in this high-risk group are a clinical priority. Attention Deficit Hyperactivity Disorder (ADHD) is one the most prevalent psychiatric disorders in children with 22q11.2DS, particularly the inattentive subtype. The aim of this study was to test the hypothesis that ADHD inattention symptoms predict later psychotic symptoms and/or psychotic disorder in those with 22q11.2DS. 250 children and adolescents with 22q11.2DS without psychotic symptoms at baseline took part in a longitudinal study. Assessments were performed using well-validated structured diagnostic instruments at two time points (T1 (mean age = 11.2, SD = 3.1) and T2 (mean age = 14.3, SD = 3.6)). Inattention symptoms at T1 were associated with development of psychotic symptoms at T2 (OR:1.2, p = 0.01) but weak associations were found with development of psychotic disorder (OR:1.2, p = 0.15). ADHD diagnosis at T1 was strongly associated with development of psychotic symptoms at T2 (OR:4.5, p < 0.001) and psychotic disorder (OR:5.9, p = 0.02). Our findings that inattention symptoms and the diagnosis of ADHD are associated with subsequent psychotic outcomes in 22q11.2DS have important clinical implications. Future studies examining the effects of stimulant and other ADHD treatments on individuals with 22q11.2DS are warranted.

Comorbid Personality Disorders in Individuals With an At-Risk Mental State for Psychosis: A Meta-Analytic Review

Increasing evidence shows that personality pathology is common among patients at clinical high risk (CHR) for psychosis. Despite the important impact that this comorbidity might have on presenting high-risk psychopathology, psychological functioning, and transition to full psychotic disorders, the relationship between personality syndromes and CHR state has received relatively little empirical attention. The present meta-analytic review aimed at 1) estimating the prevalence rates of personality disorders (PDs) in CHR individuals and 2) examining the potential role of PDs in predicting transition from CHR state to a full-blown psychotic disorder. The systematic search of the empirical literature identified 17 relevant studies, including a total of 1,868 CHR individuals. Three distinct meta-analyses were performed to provide prevalence estimates of PDs in the CHR population. The first and more comprehensive meta-analysis focused on any comorbid PD (at least one diagnosis), the second one focused on schizotypal personality disorder (SPD), and the last one focused on borderline personality disorder (BPD). Moreover, a narrative review was presented to define the predictive role of personality disorders in promoting more severe outcomes in CHR patients. The findings showed that the prevalence rate of personality disorders in CHR patients was 39.4% (95% CI [26.5%-52.3%]). More specifically, 13.4% (95% CI [8.2%-18.5%]) and 11.9% (95% CI [0.73%-16.6%]) of this clinical population presented with SPD and BPD, respectively. Finally, the studies examining the effects of baseline personality diagnoses on conversion to psychotic disorders showed contradictory and insufficient results concerning the potential significant impact of SPD. Conversely, no effect of BPD was found. This meta-analytic review indicated that the CHR population includes a large subgroup with serious personality pathology, that may present with attenuated psychotic symptoms conjointly with distinct and very heterogeneous personality features. These findings support the need for improved understanding of both core psychological characteristics of CHR patients and differentiating aspects of personality that could have relevant clinical implications in promoting individualized preventive interventions and enhancing treatment effectiveness.

Variance of IQ is partially dependent on deletion type among 1,427 22q11.2 deletion syndrome subjects

The 22q11.2 deletion syndrome is caused by non-allelic homologous recombination events during meiosis between low copy repeats (LCR22) termed A, B, C, and D. Most patients have a typical LCR22A-D (AD) deletion of 3 million base pairs (Mb). In this report, we evaluated IQ scores in 1,478 subjects with 22q11.2DS. The mean of full scale IQ, verbal IQ, and performance IQ scores in our cohort were 72.41 (standard deviation-SD of 13.72), 75.91(SD of 14.46), and 73.01(SD of 13.71), respectively. To investigate whether IQ scores are associated with deletion size, we examined individuals with the 3 Mb, AD (n = 1,353) and nested 1.5 Mb, AB (n = 74) deletions, since they comprised the largest subgroups. We found that full scale IQ was decreased by 6.25 points (p = .002), verbal IQ was decreased by 8.17 points (p = .0002) and performance IQ was decreased by 4.03 points (p = .028) in subjects with the AD versus AB deletion. Thus, individuals with the smaller, 1.5 Mb AB deletion have modestly higher IQ scores than those with the larger, 3 Mb AD deletion. Overall, the deletion of genes in the AB region largely explains the observed low IQ in the 22q11.2DS population. However, our results also indicate that haploinsufficiency of genes in the LCR22B-D region (BD) exert an additional negative impact on IQ. Furthermore, we did not find evidence of a confounding effect of severe congenital heart disease on IQ scores in our cohort.

Prevalence and Clinical Significance of Symptoms at Ultra High Risk for Psychosis in Children and Adolescents with Obsessive⁻Compulsive Disorder: Is There an Association with Global, Role, and Social Functioning?

In literature nothing is known about the clinical significance of Ultra High Risk (UHR) symptoms in children and adolescents with diagnosis of obsessive–compulsive disorder (OCD). In this study, we examined the prevalence of UHR symptoms and their relationship with severity of obsessive–compulsive symptomatology, global, social, and role functioning, and level of associated depressive symptoms in a clinical sample (n = 51) of children and adolescents aged between 8 and 17 years with a diagnosis of OCD. The prevalence of UHR symptoms in this sample was 43.1%. We divided the whole sample into two groups: children and adolescents with OCD and UHR symptoms (n = 22) and children and adolescents with OCD without UHR symptoms (n = 29). Our findings suggest that the group with OCD and UHR symptoms shows worse global, social, and role functioning than the group with OCD without UHR symptoms. No differences were found on the severity of obsessive–compulsive symptomatology, the number of psychiatric diagnoses associated, and the level of depressive symptoms. The presence of UHR symptoms in children and adolescents with OCD could cause significant functional impairment and should be considered in order to plan specific and targeted therapeutic interventions.

All that glitters is not gold: prevalence and relevance of psychotic-like experiences in clinical sample of children and adolescents aged 8-17 years old

AIM

Recent studies have examined the prevalence of psychotic-like experiences (PLEs) and their relationship with functioning, psychopathology and distress in adult and mixed young adult and adolescent samples. There is, however, a lack of knowledge about the prevalence and clinical weight of PLEs in clinical child and adolescent (CAD) populations. Available research has primarily been conducted on community populations, and even clinical samples mostly used self-reported questionnaires. These studies also recruited participants 12 years old and older, with a consequent lack of information on children from 8 to 11 years old. We examined the prevalence of PLEs and their relationship with psychiatric diagnosis, functioning, intelligence quotient (IQ), anxiety and depressive symptoms in a clinical sample aged 8-17 years old.

METHODS

The study was conducted on a clinical sample of 46 CAD with PLEs compared to a clinical sample of 60 CAD without PLEs. The two groups were compared on global, social and role functioning, IQ, anxiety and depressive symptoms, and number of psychiatric diagnoses.

RESULTS

Global, role and social functioning were significantly lower in the CAD clinical sample with PLEs. These significant differences were maintained when the covariate IQ, number of psychiatric diagnoses or level of anxiety or depression was added. No significant age-related differences in the presence of PLEs were found.

CONCLUSION

The findings of this study show that PLEs are common in a clinical sample of CAD, even those under 12 years old. The presence of PLEs should therefore be investigated and considered in planning treatment of non-psychotic psychiatric disorders in CAD.

Use of Transcranial Direct Stimulation in the Treatment of Negative Symptoms of Schizophrenia

Schizophrenia is a debilitating disease that affects approximately 1% of the population. Negative symptoms are among the major determinants of the functional impairment and a significant proportion of patients with negative symptoms will continue to experience these symptoms despite antipsychotic medications. There are promising results in the application of brain stimulation, particularly transcranial direct current stimulation (tDCS), for the reduction of negative symptoms of schizophrenia. However, findings are still controversial. This is a selective review of the literature published between 2011 and 2017 on use of tDCS in treatment of negative symptoms of schizophrenia. We included only randomized controlled trials where schizophrenia and negative symptoms were assessed using any psychometrically validated scale (eg, Positive and Negative Symptoms Scale or Scale for the Assessment of Negative Symptoms). Studies of participants with neurological conditions were excluded, as were those that did not report any symptom outcome variables. Only 5 studies are included. Three studies showed a decrease of negative symptoms. The other studies did not show any therapeutic effects of tDCS in the severity of positive and negative symptoms compared to controls. Our findings suggest that negative symptoms in schizophrenia can be treated with tDCS over the dorsolateral prefrontal cortex, but results are affected by several factors, such as the electrode montage, the concomitant medication, the homogeneity of the sample, the intensity of the tDCS treatment. Further randomized, double-blinded, sham-controlled studies in large samples are still needed to establish the effectiveness of the tDCS in the treatment of negative symptoms in schizophrenia, but there is the potential for tDCS to become a useful complementary treatment option in this population.

Subthreshold Psychosis in 22q11.2 Deletion Syndrome: Multisite Naturalistic Study

Nearly one-third of individuals with 22q11.2 deletion syndrome (22q11.2DS) develop a psychotic disorder during life, most of them by early adulthood. Importantly, a full-blown psychotic episode is usually preceded by subthreshold symptoms. In the current study, 760 participants (aged 6-55 years) with a confirmed hemizygous 22q11.2 microdeletion have been recruited through 10 medical sites worldwide, as part of an international research consortium. Of them, 692 were nonpsychotic and with complete measurement data. Subthreshold psychotic symptoms were assessed using the Structured Interview for Prodromal Syndromes (SIPS). Nearly one-third of participants met criteria for positive subthreshold psychotic symptoms (32.8%), less than 1% qualified for acute positive subthreshold symptoms, and almost a quarter met criteria for negative/disorganized subthreshold symptoms (21.7%). Adolescents and young adults (13-25 years) showed the highest rates of subthreshold psychotic symptoms. Additionally, higher rates of anxiety disorders and attention deficit/hyperactivity disorder (ADHD) were found among the study participants with subthreshold psychotic symptoms compared to those without. Full-scale IQ, verbal IQ, and global functioning (GAF) scores were negatively associated with participants' subthreshold psychotic symptoms. This study represents the most comprehensive analysis reported to date on subthreshold psychosis in 22q11.2DS. Novel findings include age-related changes in subthreshold psychotic symptoms and evidence that cognitive deficits are associated with subthreshold psychosis in this population. Future studies should longitudinally follow these symptoms to detect whether and how early identification and treatment of these manifestations can improve long-term outcomes in those that eventually develop a psychotic disorder.

Prevalence and treatment of psychiatric disorders other than psychosis in children and adolescents with 22q11DS: Examining associations with social and role functioning

Individuals with chromosome 22q11 deletion syndrome (22q11DS) have high rates of psychotic disorders. Less is known about their psychopathology and how it is treated prior to the peak period of risk for psychotic disorder. There is also a lack of evidence on how functioning is impacted by psychopathology in this population. The aim of this study was to investigate the prevalence and treatment of non-psychotic psychiatric disorders, and how these factors are associated with psychosocial functioning in children and adolescents with 22q11DS. 126 individuals with 22q11DS aged 8-17 participated in the study. Participants were assessed for psychiatric diagnoses, social and role functioning, anxiety and depressive symptoms and IQ. Information on current treatments was collected. 52.4% of the sample presented with at least one psychiatric disorder. Mood and anxiety disorders were the most frequent, followed by behavioural disorder. Individuals with a psychiatric disorder had significantly lower general, role and social functioning. Only 27% of participants with a psychiatric diagnosis were receiving any mental health treatment at the time of assessment. Findings suggest the high prevalence of psychiatric disorders in youth with 22q11DS, which significantly impacts psychosocial functioning. Despite this, psychiatric disorders tend to remain untreated in this population.

Clinical presentation of Attenuated Psychosis Syndrome in children and adolescents: Is there an age effect?

There is limited research on clinical features related to age of presentation of the Attenuated Psychosis Syndrome in children and adolescents (CAD). Based on findings in CAD with psychosis, we hypothesized that an older age at presentation of Attenuated Psychosis Syndrome would be associated with less severe symptoms and better psychosocial functioning than presentation in childhood or younger adolescence. Ninety-four CAD (age 9-18) meeting Attenuated Psychosis Syndrome criteria participated in the study. The sample was divided and compared according to the age of presentation of Attenuated Psychosis Syndrome (9-14 vs 15-18 years). The predictive value of age of Attenuated Psychosis Syndrome presentation was investigated using receiver operating characteristic (ROC)-curve calculations. The two Attenuated Psychosis Syndrome groups were homogeneous in terms of gender distribution, IQ scores and comorbid diagnoses. Older Attenuated Psychosis Syndrome patients showed better functioning and lower depressive scores. ROC curves revealed that severity of functional impairment was best predicted using an age of presentation cut-off of 14.9 years for social functioning and 15.9 years for role functioning. This study partially confirmed our hypothesis; older age at presentation of Attenuated Psychosis Syndrome was associated with less functional impairment, but age was not associated with psychotic symptoms.

Visual perception skills: a comparison between patients with Noonan syndrome and 22q11.2 deletion syndrome

Ventral and dorsal streams are visual pathways deputed to transmit information from the photoreceptors of the retina to the lateral geniculate nucleus and then to the primary visual cortex (V1). Several studies investigated whether one pathway is more vulnerable than the other during development, and whether these streams develop at different rates. The results are still discordant. The aim of the present study was to understand the functionality of the dorsal and the ventral streams in two populations affected by different genetic disorders, Noonan syndrome (NS) and 22q11.2 deletion syndrome (22q11.2DS), and explore the possible genotype-phenotype relationships. 'Form coherence' abilities for the ventral stream and 'motion coherence' abilities for the dorsal stream were evaluated in 19 participants with NS and 20 participants with 22q11.2DS. Collected data were compared with 55 age-matched controls. Participants with NS and 22q11.2DS did not differ in the form coherence task, and their performance was significantly lower than that of controls. However, in the motion coherence task, the group with NS and controls did not differ, and both obtained significantly higher scores than the group with 22q11.2DS. Our findings indicate that deficits in the dorsal stream are related to the specific genotype, and that in our syndromic groups the ventral stream is more vulnerable than the dorsal stream.

No age effect in the prevalence and clinical significance of ultra-high risk symptoms and criteria for psychosis in 22q11 deletion syndrome: Confirmation of the genetically driven risk for psychosis?

BACKGROUND

The 22q11.2 deletion syndrome (22q11DS) is one of the highest known risk factors for schizophrenia. Thus, the detection of 22q11DS patients at particularly high risk of psychosis is important, yet studies on the clinical significance of the widely used ultra-high risk (UHR) criteria in 22q11DS are inconclusive. Since age was reported to moderate clinical significance of UHR symptoms in community samples, we explored whether age at presentation of UHR symptoms and criteria may explain part of this heterogeneity.

METHODS

111 patients with 22q11DS (8-30 years; 15.7±4.7) were assessed for UHR symptoms/criteria. Information on diagnoses, psychosocial functioning, and IQ were collected.

RESULTS

Any UHR symptom was reported by 38.7%, any UHR criterion by 27%. No significant influence of age on the prevalence of UHR symptoms or criteria was detected. Moreover, age did not significantly modulate the association between UHR symptoms and functioning. However, significant interaction terms suggested that younger age groups were more likely to meet UHR criteria in the presence of UHR symptoms compared to the adult group.

DISCUSSION

Compared to the general population, prevalence of UHR symptoms and criteria was 3.8-fold and 20.8-fold in our 22q11DS sample. Contrary to the general population, age only modulated the prevalence of UHR criteria among those with UHR symptoms, but not their prevalence per se or their clinical significance. This suggests that UHR symptoms might develop as a trait factor in terms of a genetically driven schizotypal disposition in 22q11DS, thus necessitating future studies on psychosis-risk indicators in this genetic high-risk group.

Efficacy of romantic and sexual psycho-educational training for adolescent with high-functioning autism spectrum disorder: A pilot study

Introduction

Romantic and sexual functioning in individuals with autism spectrum disorder (ASD) are understudied. Recent findings evidenced that adolescents and adults with present romantic and sexual behaviors comparable with their neurotypical peers. However, it is worth to note that dysfunctional and inappropriate romantic and sexual behaviors are often described in this population.

Objectives

To investigate efficacy of a psycho-educational training in a small group of adolescent with high-functioning ASD (HFA, QI > 70).

Methods

Six adolescents (all males, range age 14–16 years) have been evaluated before (T0) and after (T1) a 10-session sexual and romantic psycho-educational structured group training, of 90′ each session. Clinical evaluation included parent-report questionnaires, as SBS for sexual behaviors and CBCL for behavioral problems, and a self-report questionnaire for sexual behaviors, called SESAMO. Moreover, autistic symptoms were investigated with ADOS-2 at T0.

Results

Preliminary analysis revealed a statistically significant differences between T0 and T1 in sexual education (P = 0.02) and frequency of dysfunctional sexual behaviors (P = 0.02) of SBS and in sexual expectations about the partner in SESAMO (P = 0.04). No differences were found in CBCL.

Conclusion

Preliminary results showed an improvement of romantic and sexual functioning in adolescent boys with HFA, as reported by either parents and adolescents, after participating to a structured psycho-educational training. More sexual education and information, less inappropriate sexual behaviors and more-appropriate expectations about potential partner were reported at the end of the training. These results should be confirmed in studies including larger ASD and control sample.

Ultra high risk status and transition to psychosis in 22q11.2 deletion syndrome

The 22q11.2 deletion syndrome (22q11DS) is characterized by high rates of psychotic symptoms and schizophrenia, making this condition a promising human model for studying risk factors for psychosis. We explored the predictive value of ultra high risk (UHR) criteria in a sample of patients with 22q11DS. We also examined the additional contribution of socio-demographic, clinical and cognitive variables to predict transition to psychosis within a mean interval of 32.5 ± 17.6 months after initial assessment. Eighty-nine participants with 22q11DS (age range: 8-30 years; mean 16.1 ± 4.7) were assessed using the Structured Interview for Psychosis-Risk Syndromes. Information on Axis I diagnoses, internalizing and externalizing symptoms, level of functioning and IQ was also collected. At baseline, 22 (24.7%) participants met UHR criteria. Compared to those without a UHR condition, they had a significantly lower functioning, more frequent anxiety disorders, and more severe psychopathology. Transition rate to psychosis was 27.3% in UHR and 4.5% in non-UHR participants. Cox regression analyses revealed that UHR status significantly predicted conversion to psychosis. Baseline level of functioning was the only other additional predictor. This is the first study investigating the predictive value of UHR criteria in 22q11DS. It indicates that the clinical path leading to psychosis is broadly comparable to that observed in other clinical high-risk samples. Nevertheless, the relatively high transition rate in non-UHR individuals suggests that other risk markers should be explored in this population. The role of low functioning as a predictor of transition to psychosis should also be investigated more in depth.

Indicated prevention with long-chain polyunsaturated omega-3 fatty acids in patients with 22q11DS genetically at high risk for psychosis. Protocol of a randomized, double-blind, placebo-controlled treatment trial

AIM

It has been found that long-chain omega-3 polyunsaturated fatty acids (PUFAs) reduce the risk of progression to first episode of psychosis (FEP) and may offer a safe and efficacious strategy for selective and indicated prevention in young people with ultra-high-risk (UHR) states. An opportunity for exploring the trajectory of FEP and for investigating the efficacy of preventive treatments exists in 22q11.2 deletion syndrome (22q11DS), which has a 30% psychotic transition rate. The fact that 22q11DS patients are more homogeneous than other UHR groups and are characterized by high level of negative symptoms provides a strong rationale for the use of PUFAs. The principal aim of the present trial is to investigate the effects of PUFAs in individuals with 22q11DS who are at UHR for developing FEP.

METHODS

A prospective, randomized, double-blind, placebo-controlled, single-centre study design will be used. Eighty individuals aged 12-26 will be randomly assigned to two treatment conditions.

RESULTS

The experimental group will receive PUFAs. The placebo group will receive paraffin oil. Standard clinical assessments and neuropsychological tests will be performed at baseline and at 8-, 12-, 26- and 52-week follow-up. Blood samples will be collected at baseline and after 12 weeks. This study is registered as an International Standard RCT, number 02070211. The corresponding author is supported by a NARSAD Young Investigator Award.

CONCLUSIONS

This is the protocol of a planned study that aims to test the efficacy of PUFAs in the prodromal phase of FEP, in a specific syndrome where there is strong evidence that a high genetic load is involved in the disorder.

Cognitive behavioural therapy for auditory hallucinations in schizophrenia: A review

AIM

To provide an updated of recent findings about efficacy of cognitive-behavior therapy (CBT) in reduction of command hallucinations.

METHODS

PubMed/MEDLINE, Cochrane Library, the Cumulative Index to Nursing and Allied Health Literature, PsycINFO, ClinicalTrial.gov searches were performed using the keywords “hallucinations”, “behavioural therapy” and “ cognitive therapy” in order to identify relevant articles published during the years of 2011 to 2016. No language limits were used. Studies conducted within control group, reviews, editorials, were excluded. Data on efficacy, acceptability and tolerability were extracted by three authors independently. Disagreements were resolved in a consensus meeting or by another reviewer.

RESULTS

A total of eight articles were eligible for inclusion. Two are randomized clinical trials (RCTs) and six are observational studies. The two RCTs included showed a greater efficacy of CBT compared to standard care on auditory hallucinations (AHs). Nevertheless, they considered different CBT models, particularly Treatment of Resistant Command Hallucinations and Cognitive Therapy for Command Hallucinations. As regards non RCT-studies, all papers included showed reduction on frequency and severity of AHs and distress related to them. However, the lack of content details within non-RCTs studies decreased their comparability. In terms of predictive variables, our findings show that negative symptoms at baseline appeared to be the strongest predictor of the treatment efficacy. Indeed, negative symptoms showed a significant negative correlation on outcome.

CONCLUSION

Although more conclusive studies are still needed, we found some preliminary evidence for the efficacy of CBT in the treatment of command hallucinations.

Twelve-month psychosis-predictive value of the ultra-high risk criteria in children and adolescents

OBJECTIVE

The validity of current ultra-high risk (UHR) criteria is under-examined in help-seeking minors, particularly, in children below the age of 12 years. Thus, the present study investigated predictors of one-year outcome in children and adolescents (CAD) with UHR status.

METHOD

Thirty-five children and adolescents (age 9-17 years) meeting UHR criteria according to the Structured Interview for Psychosis-Risk Syndromes were followed-up for 12 months. Regression analyses were employed to detect baseline predictors of conversion to psychosis and of outcome of non-converters (remission and persistence of UHR versus conversion).

RESULTS

At one-year follow-up, 20% of patients had developed schizophrenia, 25.7% had remitted from their UHR status that, consequently, had persisted in 54.3%. No patient had fully remitted from mental disorders, even if UHR status was not maintained. Conversion was best predicted by any transient psychotic symptom and a disorganized communication score. No prediction model for outcome beyond conversion was identified.

CONCLUSIONS

Our findings provide the first evidence for the predictive utility of UHR criteria in CAD in terms of brief intermittent psychotic symptoms (BIPS) when accompanied by signs of cognitive impairment, i.e. disorganized communication. However, because attenuated psychotic symptoms (APS) related to thought content and perception were indicative of non-conversion at 1-year follow-up, their use in early detection of psychosis in CAD needs further study. Overall, the need for more in-depth studies into developmental peculiarities in the early detection and treatment of psychoses with an onset of illness in childhood and early adolescence was further highlighted.

Failure to learn a new spatial format in children with developmental dyslexia

A general problem in studying children with developmental dyslexia is how to separate inefficiency in learning on the one hand from exposure to written texts on the other. To evaluate dyslexic children's learning abilities with graphemic materials, we tested their improvement in a condition that minimized previous experience with words (i.e., “novel words”) and with the standard, horizontal spatial letter array (i.e., a non-canonical “zigzag” format). We selected five pairs of children with dyslexia and (younger) typically developing readers matched for reading speed and accuracy in these specific conditions. Reading performance on novel words in the zigzag format was measured in 23 sessions; learning curves were fitted by power functions. Similar to typically developing readers, children with dyslexia improved their reading of novel words presented in the new format; however, their rate of learning was slower than that of typically developing readers. Furthermore, their learning to read in the new format did not generalize to novel untrained items, whereas significant generalization was present in typically developing readers. As the failure to generalize learning of the spatial format could not be attributed to reduced experience, it indicates a genuine disability and points to impaired perceptual learning as a factor in developmental dyslexia.

The eye-voice lead during oral reading in developmental dyslexia

In reading aloud, the eye typically leads over voice position. In the present study, eye movements and voice utterances were simultaneously recorded and tracked during the reading of a meaningful text to evaluate the eye-voice lead in 16 dyslexic and 16 same-age control readers. Dyslexic children were slower than control peers in reading texts. Their slowness was characterized by a great number of silent pauses and sounding-out behaviors and a small lengthening of word articulation times. Regarding eye movements, dyslexic readers made many more eye fixations (and generally smaller rightward saccades) than controls. Eye movements and voice (which were shifted in time because of the eye-voice lead) were synchronized in dyslexic readers as well as controls. As expected, the eye-voice lead was significantly smaller in dyslexic than control readers, confirming early observations by Buswell (1921) and Fairbanks (1937). The eye-voice lead was significantly correlated with several eye movements and voice parameters, particularly number of fixations and silent pauses. The difference in performance between dyslexic and control readers across several eye and voice parameters was expressed by a ratio of about 2. We propose that referring to proportional differences allows for a parsimonious interpretation of the reading deficit in terms of a single deficit in word decoding. The possible source of this deficit may call for visual or phonological mechanisms, including Goswami's temporal sampling framework.

Developmental dyslexia in a regular orthography: can the reading profile be reduced to strategic control?

In languages with regular orthographies, the identification of different forms of reading impairment (such as surface or phonological dyslexia) has proved elusive. Alternatively, it has been proposed that different patterns of errors depend upon strategic choices on the part of the reader. The present study aimed to test this strategic interpretation by evaluating the effectiveness of instructions to read quickly (or accurately) in modifying the reading rate and types of errors of dyslexic children. Further, drawing on an error classification based on the contrast between sounding-out behaviour and word substitution, we examined the types of reading error that best characterize the deficit in a language with regular orthography (Italian). Thirty children with dyslexia and 30 chronologically age-matched controls read aloud passages and word lists with instructions to emphasize either rate or accuracy. When asked to read quickly, children with dyslexia increased their reading rate (although less than skilled children). However, the type of instructions had little influence on reading errors. Therefore, the results did not support the view that strategic control has an important role in modulating the types of reading errors made by children with dyslexia. For word lists, sounding-out behaviour, errors in stress assignment, and form-related nonwords were useful to correctly identifying children with dyslexia. For text passages, sounding-out behaviour and form-related errors were the best predictors of group membership. Thus, specific types of errors are a fundamental component of the reading deficit in children who speak a language with regular orthography over and above their reading slowness.

Adolescents at ultra-high risk for psychosis with and without 22q11 deletion syndrome: a comparison of prodromal psychotic symptoms and general functioning

OBJECTIVE

Genetic syndromes related to psychosis have become increasingly important for exploring the trajectory that leads to psychosis onset. A very significant opportunity for mapping earlier phases of the trajectory can be found in 22q11.2 deletion syndrome (22q11DS). Comparative studies have shown that schizophrenic disorder in 22q11DS largely resembles schizophrenia in the general population, but only few studies have investigated the features of prodromal symptoms in 22q11DS. The aim of the present study was to investigate differences and similarities between two samples: patients with 22q11DS clinically at risk for psychotic onset (UHR+22q11DS group) and patients at clinical high risk for psychotic onset (UHR group).

METHOD

The study was conducted on a sample of 30 individuals UHR+22q11DS and 81 individuals at UHR without 22q11DS. The two groups were compared on positive, negative and depressive symptoms, level of general functioning and IQ.

RESULTS

There was a significant group difference in negative symptoms, but no significant differences were found for positive, global and total symptoms. The UHR+22q11DS group showed a lower level of general functioning. The clinical profile of the UHR+22q11DS group was clearly more homogeneous.

CONCLUSIONS

Even if the two UHR groups are comparable in terms of positive symptoms, the UHR+22q11DS have a specific clinical pattern characterized by higher negative symptoms, lower general functioning and an older age of onset of the UHR state. This finding may be of clinical value for the development of specific therapeutic intervention for UHR+22q11DS, and of theoretical value since the two groups may share only some underlying etiopathogenetic mechanisms.

[GnRH agonists and antagonists in the preoperative therapy of uterine fibroids: literature review]

Uterine leiomyomas are the most frequent gynecological benign tumors. Their growth is regulated by ovarian steroids, therefore a hypoestrogenic state, like menopause or pharmacologically induced pseudo-menopause by GnRH-agonists or GnRH-antagonists, is associated with the decrease of their volume. This volume reduction allows a less invasive surgical procedure and may reduce the amount of blood loss during surgery. Therefore, GnRH-agonists and antagonists are used in presurgical treatment of uterine fibromatosis. This review analyses the effects of GnRH-agonists and GnRH-antagonists therapies. GnRH-agonists produce a down-regulation of GnRH receptor, while GnRH-antagonists compete with endogenous GnRH for pituitary binding sites. Due to the lack of any intrinsic activity of GnRH-antagonists, the characteristic initial flare-up observed with GnRH-agonist treatment is absent. So, GnRH-antagonists rapidly suppress gonadotropin release within 4-8 h, while GnRH-agonists show clinical effects after 2 or 3 weeks of treatment. GnRH-antagonist activity is dose-dependent so it is possible to adjust the dose to obtain the proper levels of inhibition. The GnRH-agonist presurgical treatment usually is a short-term therapy (3-6 months), because it causes side-effects like menopause symptoms. GnRH-antagonist clinical effects can be achieved with a short-time therapy too. Their side-effects include flushes and head-ache. After stopping therapy with both drugs, leiomyomas rapidly achieve their original size while side-effects disappear. Further studies are necessary to establish the use of GnRH-antagonists in leiomyomas therapy, but in Italy this is not possible because their use is not approved.
