[PMID: 33003515 PMCID: PMC7600970 DOI: 10.3390/brainsci10100689] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2020] [Revised: 09/28/2020] [Accepted: 09/28/2020] [Indexed: 11/28/2022] Open
Abstract
Background: Bipolar Disorders (BD) in youth are a heterogeneous condition with different phenomenology, patterns of comorbidity and outcomes. Our aim was to explore the effects of gender; age at onset (prepubertal- vs. adolescent-onset) of BD; and elements associated with attention deficit hyperactivity disorder (ADHD) and Substance Use Disorder (SUD) comorbidities, severe suicidal ideation or attempts, and poorer response to pharmacological treatments. Method: 117 youth (69 males and 57 females, age range 7 to 18 years, mean age 14.5 ± 2.6 years) consecutively referred for (hypo)manic episodes according to the Diagnostic and Statistical Manual of Mental Disorders, 54th ed (DSM 5) were included. Results: Gender differences were not evident for any of the selected features. Prepubertal-onset BD was associated with higher rates of ADHD and externalizing disorders. SUD was higher in adolescent-onset BD and was associated with externalizing comorbidities and lower response to treatments. None of the selected measures differentiated patients with or without suicidality. At a 6-month follow up, 51.3% of the patients were responders to treatments, without difference between those receiving and not receiving a psychotherapy. Clinical severity at baseline and comorbidity with Conduct Disorder (CD) and SUD were associated with poorer response. Logistic regression indicated that baseline severity and number of externalizing disorders were associated with a poorer outcome. Conclusions: Disentangling broader clinical conditions in more specific phenotypes can help timely and focused preventative and therapeutic interventions.

Predicting individual improvement in schizophrenia symptom severity at 1-year follow-up: Comparison of connectomic, structural, and clinical predictors. Hum Brain Mapp 2020; 41:3342-3357. [PMID: 32469448 PMCID: PMC7375115 DOI: 10.1002/hbm.25020] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2019] [Revised: 01/13/2020] [Accepted: 04/13/2020] [Indexed: 12/25/2022] Open
Abstract
In a machine learning setting, this study aims to compare the prognostic utility of connectomic, brain structural, and clinical/demographic predictors of individual change in symptom severity in individuals with schizophrenia. Symptom severity at baseline and 1-year follow-up was assessed in 30 individuals with a schizophrenia-spectrum disorder using the Brief Psychiatric Rating Scale. Structural and functional neuroimaging was acquired in all individuals at baseline. Machine learning classifiers were trained to predict whether individuals improved or worsened with respect to positive, negative, and overall symptom severity. Classifiers were trained using various combinations of predictors, including regional cortical thickness and gray matter volume, static and dynamic resting-state connectivity, and/or baseline clinical and demographic variables. Relative change in overall symptom severity between baseline and 1-year follow-up varied markedly among individuals (interquartile range: 55%). Dynamic resting-state connectivity measured within the default-mode network was the most accurate single predictor of change in positive (accuracy: 87%), negative (83%), and overall symptom severity (77%) at follow-up. Incorporating predictors based on regional cortical thickness, gray matter volume, and baseline clinical variables did not markedly improve prediction accuracy and the prognostic utility of these predictors in isolation was moderate (<70%). Worsening negative symptoms at 1-year follow-up were predicted by hyper-connectivity and hypo-dynamism within the default-mode network at baseline assessment, while hypo-connectivity and hyper-dynamism predicted worsening positive symptoms. Given the modest sample size investigated, we recommend giving precedence to the relative ranking of the predictors investigated in this study, rather than the prediction accuracy estimates.

Abstract
BACKGROUND The hypothesis that bipolar disorder presents before puberty with atypical mania has proved to be controversial. Published academic perspectives on the validity of Paediatric Bipolar Disorder (PBD) appear to vary between the United States and the rest of the world. METHODS We examined the perspectives of articles citing four seminal articles. The citing articles were grouped as either supportive or non-supportive of the PBD hypothesis, and the perspectives of the articles by US authors were compared with those by non-US authors. RESULTS There were 787 citing articles commenting on PBD, mostly published in US-based journals. Most authors were affiliated with several US institutions. Among the 624 articles with US authorship, the majority (83%) supported PBD. Of the 163 articles by non-US authors, most (60%) supported the traditional view that bipolar disorders are rare before mid-adolescence. Published academic perspectives in favour of the PBD hypothesis are mostly concentrated in several US institutions. CONCLUSION There is majority support for PBD among citing articles from the United States, whereas the traditional perspective predominates in articles from most other countries.

Abstract
AIM The timely identification and treatment of psychosis are increasingly the focus of early interventions, with research targeting the initial high-risk period in the months following first-episode hospitalization. Ongoing treatment after stabilization is also essential in the years following a first-episode psychosis (FEP), but has received less research attention. In this study, variables that could impact continued psychiatric service utilization by adolescents following their FEP and temporal patterns in service utilization are examined. METHODS Families of 52 adolescents (aged 14.4 ± 2.5 years) discharged following a hospitalization for FEP were contacted two or more years following the adolescents' discharge. A chart review (Time 1) of hospital records provided clinical data on each adolescent's psychiatric diagnosis, symptoms, illness course, medications and family history. Follow-up (Time 2) data were collected from parents/caregivers using a questionnaire enquiring about post-discharge treatment history and service utilization. RESULTS Bivariate analyses were conducted to identify Time 1 variables associated with psychiatric service utilization at Time 2. Significant variables were included in a logistic regression model and three variables were independently associated with continued service utilization: having a primary diagnosis of schizophrenia (odds ratio (OR) = 24.0; P = 0.02), not having a first-degree relative with depression (OR = 0.12; P = 0.05) and fewer months since the last inpatient discharge (OR = 0.92; P = 0.02). CONCLUSIONS Findings suggest: (1) the importance of early diagnosis, (2) that a relative with depression may negatively influence the adolescent's ongoing service utilization, and (3) that 18 months post-discharge may be a critical time to review treatment strategies and collaborate with youth and families to ensure appropriateness of services.

Abstract
To investigate the cognitive functioning of children and adolescents with bipolar illness, 112 child and adolescent psychiatric inpatients and day-hospital patients at a state psychiatric hospital were administered the Wechsler Intelligence Scale for Children–III (WISC–III) as part of an admission psychological assessment. There were 22 patients with Bipolar Disorder and 90 with other psychiatric disorders; all were between 8 and 17 years of age. The patients with Bipolar Disorder had a mean age of 14 yr., a mean Verbal IQ of 78, a mean Performance IQ of 76, and a mean Full Scale IQ of 75. When their WISC–III scores were compared with those who had Schizophrenia Spectrum disorders (Schizophrenia and Schizoaffective Disorder), Psychosis Not Otherwise Specified, Attention Deficit Hyperactivity Disorder, and Conduct Disorder and Oppositional Defiant Disorder, there were no significant between-group mean differences for Verbal IQ, but patients with Bipolar Disorder had a significantly lower mean Performance IQ than those with ADHD and those with Conduct Disorder and Oppositional Defiant Disorder. Contrary to the expectation that the patients with Bipolar Disorder might have better sustained attention (higher Digit Span scores) than those with Schizophrenia Spectrum disorders and worse visual processing speed (lower Coding scores) than the other diagnostic groups, the bipolar patients' Digit Span and Coding scores did not differ significantly from those of the other groups. The patients with Psychosis, Not Otherwise Specified had significantly lower mean Performance IQ, Full Scale IQ, and Coding than the ADHD and the Conduct Disorder and Oppositional Disorder groups.

Abstract
Schizophrenia is a neurodevelopmental disorder with a multifactorial etiology. Pediatric schizophrenia consists of early-onset schizophrenia (onset prior to age 18 years) and childhood-onset schizophrenia (onset prior to age 13 years). Adolescence has been established as a critical period for neuronal pruning; hence, with earlier the onset of symptoms, there may be disruption in the normal process of neuronal development, causing impairments with memory, abstract thinking, and emotion regulation. Although the lifetime prevalence of schizophrenia is 1% in the general population, the incidence of pediatric schizophrenia is rare. Therefore, it is important to effectively evaluate the cause of any psychosis of a child or an adolescent. An accurate history and physical, including a detailed neurological examination, are vitally important, as are pertinent laboratory and imaging tests to rule out the many alternative differential diagnoses that also present with psychotic symptoms. The antipsychotics continue to be significantly more effective than placebo in treating pediatric schizophrenia in combination with psychotherapy, as evidenced by the recent Recover After an Initial Schizophrenia Episode (RAISE) study. However, further study is still needed to better understand causality, improve assessment, and develop a definitive treatment algorithm.

Abstract
Given the global burden of psychotic disorders, the identification of patients with early-onset psychosis (EOP; that is, onset before the age of 18) at higher risk of adverse outcome should be a priority. A systematic search of Pubmed, Embase, and PsycInfo (1980 through August 2014) was performed to identify longitudinal observational studies assessing correlates and/or predictors of clinical, functional, cognitive, and biological outcomes in EOP. Seventy-five studies were included in the review. Using multivariate models, the most replicated predictors of worse clinical, functional, cognitive, and biological outcomes in EOP were premorbid difficulties and symptom severity (especially of negative symptoms) at baseline. Longer duration of untreated psychosis (DUP) predicted worse clinical, functional, and cognitive outcomes. Higher risk of attempting suicide was predicted by greater severity of psychotic illness and of depressive symptoms at the first episode of psychosis. Age at onset and sex were not found to be relevant predictors of outcome in most multivariate models, whereas studies using bivariate analyses yielded inconsistent results. Lower intelligence quotient at baseline predicted lower insight at follow-up, worse functional outcomes, and a diagnostic outcome of schizophrenia. Biological predictors of outcome in EOP have been little studied and have not been replicated. Lower levels of antioxidants at baseline predicted greater brain volume changes and worse cognitive functioning at follow-up, whereas neuroimaging markers such as regional cortical thickness and gray matter volume at baseline predicted remission and better insight at follow-up, respectively. EOP patients with poorer premorbid adjustment and prominent negative symptoms at initial presentation are at risk of poor outcome. They should therefore be the target of careful monitoring and more intensive interventions to address whether the disease course can be modified in this especially severely affected group. Early intervention strategies to reduce DUP may also improve outcome in EOP.

Abstract
Lifetime prevalence of child and adolescent bipolar 1 disorder (BD1) is nearly 0.1 %. Even though it is not a frequent disorder in young people, there is an increased interest for this disorder at this age, because of the poor outcome, the severe functional impairments and the major risk of suicide. Diagnosis is complex in view of the more frequent comorbidities, the variability with an age-dependant clinical presentation, and the overlap in symptom presentation with other psychiatric disorders (e.g. disruptive disorders in prepubertal the child and schizophrenia in the adolescent). The presentation in adolescents is very similar to that in adults and in prepubertal children chronic persistent irritability and rapid mood oscillation are often at the foreground. For a while, such presentations were considered as BD-not otherwise specified (BD-NOS), which can explain the outburst of the prevalence of bipolar disorder in children in the US. Longitudinal studies that look for the outcome of such emotional dysregulations have not revealed an affiliation with bipolar disorder spectrum, but with depressive disorders in adulthood. The diagnosis of Disruptive Mood Dysregulation Disorder was proposed in the DSM-5 to identify these children and to prevent confusion with bipolar disorder. The goals of the pharmacological and psychosocial treatments are to control or ameliorate the symptoms, to avoid new episodes or recurrences, to improve psychosocial functioning and well-being, and to prevent suicide. In the US, lithium and four atypical antipsychotics have been approved by the FDA for 10 to 13-year-olds (risperidone, olanzapine, aripiprazole and quetiapine). In France, only lithium salts (after the age of 16) and aripiprazole (after the age of 13) are recommended. Psychosocial treatments, such as a familial or individual approach are developing.

Abstract
This Practice Parameter reviews the literature on the assessment and treatment of children and adolescents with schizophrenia. Early-onset schizophrenia is diagnosed using the same criteria as in adults and appears to be continuous with the adult form of the disorder. Clinical standards suggest that effective treatment includes antipsychotic medications combined with psychoeducational, psychotherapeutic, and educational interventions. Since this Practice Parameter was last published in 2001, several controlled trials of atypical antipsychotic agents for early-onset schizophrenia have been conducted. However, studies suggest that many youth with early-onset schizophrenia do not respond adequately to available agents and are vulnerable to adverse events, particularly metabolic side effects. Further research is needed to develop more effective and safer treatments.

Abstract
Childhood schizophrenia is a rare but serious developmental disorder affecting most of the fields involved in the child's adaptive functioning: motor, emotional, cognitive, and social. The clinical expression of the disorder mainly depends on the child's age and the IQ level at the time the first clinical symptoms appear. The progression of childhood schizophrenia is generally poor, with different outcome studies suggesting a continuity of the process between childhood and adulthood. This stresses the importance of diagnosing the disorder early and initiating the adapted therapeutic measures as quickly as possible, including cognitive remediation (a new therapeutic tool to correct or anticipate cognitive disorders), which can prevent pejorative development.

Abstract
This study aimed to compare 2-year outcome among individuals with early-onset (EO; <18 years) versus adult-onset (AO) first-episode, non-affective psychosis. We compared clinical and treatment characteristics of 43 EO and 189 AO patients 2 years after their inclusion in a clinical epidemiologic population-based cohort study of first-episode psychosis. Outcome variables included symptom severity, remission status, drug abuse, treatment utilization, cognition and social functioning. At baseline, EO patients were more symptomatically compromised. However, these initial baseline differences were no longer significant at the 2-year follow-up. This study challenges the findings of a larger and older literature base consisting primarily of non-comparative studies concluding that teenage onset indicates a poor outcome. Our results indicate that adolescent-onset and adult-onset psychosis have similar prognostic trajectories, although both may predict a qualitatively different course from childhood-onset psychosis.

Abstract
An inflammatory process is hypothesized in schizophrenia. Innate immunity, in particular the monocyte/macrophage system, has rarely been studied in this disorder, although alterations in microglia indicate a role for this system. Increased monocyte numbers have repeatedly been described. Toll-like receptors (TLRs) mediate the activation of monocytes. We studied the expression of the toll-like receptors TLR-2, TLR-3 and TLR-4 on CD14(+) monocytes in 31 schizophrenia patients and 31 sex- and age-matched healthy controls. Blood samples were taken and stimulated with either lipopolysaccharides (LPS), to mimic a bacterial infection, or polyI:C, to mimic a viral infection. Moreover, the intracellular concentration of interleukin-1ß (IL-1ß) in CD33(+) monocytes was estimated before and after stimulation. The intracellular concentrations of IL-1ß and the TLR surface markers were analyzed by flow cytometry. Receptor expression of TLR-3 and TLR-4, but not of TLR-2, was significantly higher in the schizophrenia patients. After stimulation, patients showed less increase in the expression of TLR-3 and TLR-4 than controls did. The IL-1ß concentration was significantly lower in patients both before and after stimulation with polyI:C, and there was a trend towards a lower concentration after LPS stimulation. The higher expression of TLR-3 and TLR-4 receptors might compensate for a functional deficit, and the lower intracellular concentrations of IL-1ß might reflect the blunted monocytic function in schizophrenia. The immunological dysfunctions might be associated with a poor clearance of pathogens in schizophrenia, which in turn could lead to a low-grade inflammatory process.

Abstract
AIM Early-onset schizophrenia (onset before adulthood) is a rare and severe form of the disorder that shows phenotypic and neurobiological continuity with adult-onset schizophrenia. Here, we provide a synthesis of keynote findings in this enriched population to understand better the neurobiology and pathophysiology of early-onset schizophrenia. METHODS A synthetic and integrative approach is applied to review studies stemming from epidemiology, phenomenology, cognition, genetics and neuroimaging data. We provide conclusions and future directions of research on early-onset schizophrenia. RESULTS Childhood and adolescent-onset schizophrenia is associated with severe clinical course, greater rates of premorbid abnormalities, poor psychosocial functioning and increased severity of brain abnormalities. Early-onset cases show similar neurobiological correlates and phenotypic deficits to adult-onset schizophrenia, but show worse long-term psychopathological outcome. Emerging technological advances have provided important insights into the genomic architecture of early-onset schizophrenia, suggesting that some genetic variations may occur more frequently and at a higher rate in young-onset than adult-onset cases. CONCLUSIONS Clinical, cognitive, genetic and imaging data suggest increased severity in early-onset schizophrenia. Studying younger-onset cases can provide useful insights into the neurobiological mechanisms of schizophrenia and the complexity of gene-environment interactions leading to the emergence of this debilitating disorder.

Abstract
BACKGROUND Over the last few decades, research regarding the age of onset of schizophrenia and its relationship with other clinical variables has been incorporated into clinical practices. However, reports of potential differences in demographic and clinical characteristics between early- and adult-onset schizophrenia spectrum disorders have been controversial. Thus, this study aims to assess differences in demographic and clinical characteristics correlated with age of illness onset in schizophrenia spectrum disorders. METHODS Data were collected from 104 patients with schizophrenia and schizoaffective disorder. Diagnosis was made via structured clinical interviews. Assessments of psychiatric symptoms and social and global functioning were completed. The effect of age of onset on demographic and clinical variables was examined using correlation analyses and binary logistic regression models. We chose 17 years of age as the cut-off for early-onset schizophrenia spectrum disorders based on a recent clinical consensus. We further investigated differences in the severity of psychopathology and other clinical variables between the early- and adult-onset groups. RESULTS The binary logistic regression analysis showed that age of onset was significantly related to the cognitive component of the Positive and Negative Syndrome Scale (PANSS) (odds ratio, OR = 0.58; 95% confidence interval, CI = 0.872-0.985; p < 0.001) and Barratt Impulsiveness Scale (BIS) score (OR = 0.94; 95% CI = 0.447-0.744; p = 0.015). Patients with early onset of schizophrenia spectrum disorders had significantly greater levels of cognitive impairment and higher impulsivity. There were significant differences between several demographic and clinical variables, including the negative symptom component of the PANSS (p < 0.001), cognitive component of the PANSS (p < 0.001), BIS score (p = 0.05), and psychological domain of quality of life (QOL) (p = 0.05), between patients with early- and adult-onset schizophrenia spectrum disorders, having controlled for the effect of the current age and duration of illness. CONCLUSIONS Our findings support the hypothesis of an influence of age of onset on illness course in patients with schizophrenia spectrum disorders. This finding may in fact be part of a separate domain worthy of investigation for the development of interventions for early symptoms of schizophrenia.

Abstract
Pediatric bipolar disorder (BPD) significantly affects the normal emotional, cognitive, and social development. The course of children and adolescents with BPD is manifested by frequent changes in symptoms polarity showing a dimensional continuum of bipolar symptoms severity from subsyndromal to mood syndromes meeting full DSM-IV criteria. Thus, early diagnosis and treatment of pediatric bipolar is of utmost importance.

Abstract
Individuals treated for psychotic disorders and mood disorders with psychotic features have a high likelihood of relapse across the life course. This study examines the relapse rate and its associated predictors for children and adolescents experiencing a first-episode and develops a statistical risk-model for prediction of time to first-relapse. A multiyear, retrospective cohort design was used to track youth, under the age of 18 years, who experienced a first-episode of psychosis, and were admitted to 1 of 6 inpatient hospital psychiatric units (N = 87). Participants were followed for at least 2 years (M = 3.9, SD = 1.3) using survival analysis. Approximately 60% of subjects experienced relapse requiring hospital readmission by the end of follow-up, with 33% readmitted within the first year and 44% within 2 years. Median survival time was 34 months. Cox proportional hazards regression identified 4 key risk factors for relapse: medication nonadherence, female gender, receiving clinical treatment, and a decline in social support before first admission.

Abstract
The management of early onset psychosis poses a significant challenge to professionals working in Child and Adolescent Mental Health Services. Young people with psychotic illness often present with a mixed clinical picture and a wide variety of attendant issues. Over the last decade there has been accumulating research, mainly based on work with adults, regarding the efficacy and effectiveness of medical and psychosocial interventions for patients with schizoaffective spectrum disorders. This article takes a symptoms-based approach, collating and summarising recent evidence, where it exists, regarding best practice when managing young people affected by schizophrenia, schizoaffective or bipolar affective disorder.

Abstract
Early onset schizophrenia (with onset before adulthood) represents a rarer and possibly more severe form of the disorder which has received particular attention in the last two decades. Current evidence strongly suggest continuity with adult onset schizophrenia, with phenomenological, cognitive, genetic and neuroimaging data pointing towards similar neurobiological correlates and clinical deficits but worse long term outcome. Future research in early onset cases is likely to increase further our insight into the neurodevelopmental origins of schizophrenia and the complex gene-environment interactions affecting its emergence.

Abstract
OBJECTIVE We examined baseline demographic and clinical profiles of youths enrolled from 2001 to 2006 in the publicly funded multicenter, randomized controlled trial Treatment of Early-Onset Schizophrenia Spectrum Disorders. METHOD Youths (8-19 years) with schizophrenia (SZ) and schizoaffective disorder were recruited at four academic sites. Diagnosis was made via structured and clinical interviews. Assessments of psychiatric symptoms and social and global functioning were included. RESULTS A total of 119 youths were enrolled. The mean age at illness onset was 11.1 +/- 3.5 years. Patients with SZ and schizoaffective disorder had similar ratings on the Positive and Negative Symptom Scale, Brief Psychiatric Rating Scale for Children, and Clinical Global Impression-Severity Scale. The overall level of functioning was similar in the two groups. A comparison to published reports of adults with SZ indicates that these youths may have more severe symptoms based on results of the Positive and Negative Symptom Scale. CONCLUSIONS This is one of the largest samples of youths with SZ spectrum disorders studied to date and the largest assessment of youths with schizoaffective disorder. High rates of symptoms and general psychopathology were noted. There was a substantial degree of social and functional impairment. The symptom profiles are consistent with, but more severe than, those reported in the adult literature.

OBJECTIVE Previous cross-sectional studies in adolescents with early-onset schizophrenia (EOS; onset of psychotic symptoms by 18 years of age) have reported patterns of generalized neurocognitive deficits as compared to healthy comparison subjects (HCSs). Here, the authors examined the longitudinal stability of neuropsychological deficits in adolescents with EOS relative to HCS and the associations of these deficits with short-term functional outcome in patients. METHOD Fifty-two subjects (26 EOS, 26 HCS) were evaluated using a comprehensive neuropsychological test battery a median of 13 months after baseline examination. The stability of scores and the relationship between baseline test performance and functional outcome in patients was explored. RESULTS Adolescents with EOS were impaired across neurocognitive domains at baseline and follow-up compared to HCSs; these deficits remained relatively stable over time. Follow-up social/communication, personal living, and community living skills were significantly related to attention/vigilance, working memory and verbal memory at baseline; individual cognitive domains were more strongly related to functional outcome than a global measure of intelligence. CONCLUSIONS Neuropsychological impairment in patients with EOS appears to remain relatively stable over time regardless of changes in clinical state. In addition, this report offers preliminary support for a longitudinal relationship between neurocognitive performance in specific domains and functional outcome.

Abstract
The purpose of the present paper was to compare currently available diagnostic guidelines for juvenile bipolar disorder with respect to utility in research and clinical practice. A systematic search of psychiatric, medical and psychological databases was conducted using the terms 'juvenile bipolar disorder', 'paediatric bipolar disorder' and 'guidelines'. Three main sets of guidelines issued by the National Institute of Health and Clinical Excellence (UK), The National Institute of Mental Health (USA) and Child Psychiatric Workshop (USA) were found. There were key differences in the recommendations made by each regarding the diagnosis and symptomatic presentation of juvenile bipolar disorder. Although the diagnosis of juvenile bipolar disorder is gaining increased recognition, its definition remains controversial. It is recommended that clinicians and researchers need to develop diagnostic guidelines that have clinical salience and can be used for future research by incorporating key features of those that are currently available.

Abstract
UNLABELLED Schizophrenia is a heterogeneous disorder, and early signs of disorder such as poor premorbid adjustment (PMA) are often present before the onset of diagnosable illness. Differences in PMA between patients may be suggestive of differing aetiological pathways. Poor PMA in schizophrenia has repeatedly been reported to be associated with male sex, earlier age at onset, illness severity, negative symptoms, and poor outcome. Studies of schizophrenia patients systematically assessed for PMA have used small patient samples and have rarely used controls. OBJECTIVE To investigate possible correlations of PMA, as measured with the Cannon-Spoor Premorbid Adjustment Scale (PAS), with such meaningful clinical characteristics as sex, age at onset, negative symptoms etc. using one of the largest samples of schizophrenia inpatients as well as controls characterised for PMA to date. METHOD PMA, diagnosis and lifetime symptoms were assessed in 316 inpatients with schizophrenia and 137 population based controls using the PAS and the Structured Clinical Interview for DSM. RESULTS Controls demonstrated better PAS scores than inpatients with schizophrenia. Earlier age at onset and negative symptoms were found to be associated with poorer PAS scores. There was no difference in PAS ratings between males and females in patients with schizophrenia. Among the control probands, females showed significantly better PAS scores than males. CONCLUSION PAS scores are worse in individuals who eventually develop schizophrenia, and the distribution of these scores among schizophrenia inpatients is correlated with specific clinical features. Earlier findings, which had reported an association with age at onset and negative symptoms in small patient samples, were substantiated. The widely reported association of poor PMA with male sex, if genuinely present, does not appear to be disease specific. Our findings suggest that PMA is in itself a valuable phenotype characteristic and that it may represent a specific biological phenotype which may be of value in sub-sample selection.

Abstract
The longitudinal course of children and adolescents with bipolar disorder (BP) is manifested by frequent changes in symptom polarity with a fluctuating course showing a dimensional continuum of bipolar symptom severity from subsyndromal to mood syndromes meeting full Diagnostic and Statistical Manual of Mental Disorders criteria. These rapid fluctuations in mood appear to be more accentuated than in adults with BP, and combined with the high rate of comorbid disorders and the child's cognitive and emotional developmental stage, may explain the difficulties encountered diagnosing and treating BP youth. Children and adolescents with early-onset, low socioeconomic status, subsyndromal mood symptoms, long duration of illness, rapid mood fluctuation, mixed presentations, psychosis, comorbid disorders, and family psychopathology appear to have worse longitudinal outcome. BP in children and adolescents is associated with high rates of hospitalizations, psychosis, suicidal behaviors, substance abuse, family and legal problems, as well as poor psychosocial functioning. These factors, in addition to the enduring and rapid changeability of symptoms of this illness from very early in life, and at crucial stages in their lives, deprive BP children of the opportunity for normal psychosocial development. Thus, early recognition and treatment of BP in children and adolescents is of utmost importance.

Abstract
Knowledge that poor premorbid adjustment (PMA) precedes illness onset in many schizophrenia cases can facilitate early detection. Increasing consideration is being given to a similar early detection strategy for bipolar disorder (BPD). Results of this preliminary investigation comparing PMA in BPD (N = 53) and schizophrenia (N = 39) outpatients revealed a significant difference at the late adolescent (F[1,58] = 4.499, p = 0.038) stage only, with specific differences in two areas of PMA: adaptation to school (t [58] = 1.83, p = 0.036) and social sexual functioning (t [58] = 2.441, p = 0.009). However, mood state may affect some PMA ratings in BPD. Depression ratings were not correlated with reported late adolescent PMA, but a significant, positive correlation was found for the childhood stage (r = 0.32, p = 0.02). Findings fail to support a trend similar to schizophrenia of deteriorating PMA in BPD; however, the approach to investigations of PMA in BPD may need to be reconsidered.

Abstract
CONTEXT Despite the high morbidity associated with bipolar disorder (BP), few studies have prospectively studied the course of this illness in youth. OBJECTIVE To assess the longitudinal course of BP spectrum disorders (BP-I, BP-II, and not otherwise specified [BP-NOS]) in children and adolescents. DESIGN Subjects were interviewed, on average, every 9 months for an average of 2 years using the Longitudinal Interval Follow-up Evaluation. SETTING Outpatient and inpatient units at 3 university centers. PARTICIPANTS Two hundred sixty-three children and adolescents (mean age, 13 years) with BP-I (n = 152), BP-II (n = 19), and BP-NOS (n = 92). MAIN OUTCOME MEASURES Rates of recovery and recurrence, weeks with syndromal or subsyndromal mood symptoms, changes in symptoms and polarity, and predictors of outcome. RESULTS Approximately 70% of subjects with BP recovered from their index episode, and 50% had at least 1 syndromal recurrence, particularly depressive episodes. Analyses of weekly mood symptoms showed that 60% of the follow-up time, subjects had syndromal or subsyndromal symptoms with numerous changes in symptoms and shifts of polarity, and 3% of the time, psychosis. Twenty percent of BP-II subjects converted to BP-I, and 25% of BP-NOS subjects converted to BP-I or BP-II. Early-onset BP, BP-NOS, long duration of mood symptoms, low socioeconomic status, and psychosis were associated with poorer outcomes and rapid mood changes. Secondary analyses comparing BP-I youths with BP-I adults showed that youths significantly more time symptomatic and had more mixed/cycling episodes, mood symptom changes, and polarity switches. CONCLUSIONS Youths with BP spectrum disorders showed a continuum of BP symptom severity from subsyndromal to full syndromal with frequent mood fluctuations. Results of this study provide preliminary validation for BP-NOS.

Abstract
Treatment-refractory early-onset schizophrenia is a rare but severe form of the disorder associated with poor premorbid function and long-term disability. The currently available evidence suggests that clozapine remains the most efficacious treatment for the amelioration of both positive and negative symptoms of the disorder and problematic aggressive behaviors. Clozapine use in children and adolescents, however, is limited by its association with hematologic adverse events and an increased frequency of seizure activity. Further studies are needed to examine the usefulness of antipsychotic combinations and of augmentation therapies to antipsychotic medications in order to treat persistent residual psychotic symptoms in children and adolescents who have schizophrenia and who have not responded to several sequential trials of antipsychotic monotherapy.

Abstract
The study describes the psychopathological and social outcome of patients treated for schizophrenia in adolescence (mean age at onset 16.0 years/SD 1.52) after a mean follow-up period of 15.4 years (10.2-21.2 years). Out of 55 patients consecutively admitted to hospital, 47 (85 %) could be traced and 39 (71 %) could be re-examined. At follow-up, 33/39 patients (85 %) had had at least one readmission. Full remission of global psychopathological symptoms [Clinical Global Impression (CGI) <or= 2] was found in 3/39 (8 %),a moderate outcome (CGI=3-5) in 22/39 (56 %), and a poor outcome (CGI=6-8) was seen in 14/39 (36 %). Severe or very severe impairments of global social functioning [Global Assessment of Social Function (GAS)< 51] were observed in 20/39 (51 %). The best predictor of global psychopathological and psychosocial outcome was type of onset (CGI: Beta=0.36, GAS: Beta=-0.37). A poor outcome was seen in 22 out of 25 cases with insidious onset. All predictors together explained 58% of the variance in the Positive and Negative Syndrome (PANSS) negative symptom ratings at follow-up. Gender, duration of first inpatient treatment and duration of untreated psychosis were of no predictive value for outcome. The nature of the diagnosis in the first episode strongly predicted the diagnosis given for the whole course after 15 years. In 26/37 cases (70 %), diagnosis at onset and overall diagnoses were the same. Our finding of an incidence of 61% insidious onset is similar to that in adult onset schizophrenia (AOS), but different to very early onset schizophrenia (VEOS), which shows a higher rate of insidious onset, cognitive impairment and poor outcome. Therefore, it seems that VEOS is a special group compared with early onset schizophrenia (EOS) and AOS.

Abstract
Awareness of bipolar spectrum disorders in children is rapidly increasing, with a more precise definition of their clinical subtypes and early signs. Paediatric bipolar disorder can lead to an important impairment in scholastic, familial and social functioning, and to a higher risk for substance abuse and suicide. In the context of a multimodal approach, the core treatment of early-onset bipolar disorder is pharmacological. This review focuses on the empirical evidence for pharmacotherapy in paediatric bipolar disorder. Mood stabilizers, including lithium, and older and newer anticonvulsivants will be considered, in mono- or polypharmacy. Atypical antipsychotics will be considered in more severe and/or treatment-resistant manic or mixed episodes. Finally, the prophylaxis of intercritical phases and the management of specific challenging conditions, such as bipolar depression and attention deficit hyperactivity disorder, with bipolar comorbidity, will be reviewed.

Abstract
BACKGROUND Kraepelin and Blueler suggested that subtle manifestations of schizophrenia are present in some persons for many years before formal diagnosis and that the severity of these is associated with outcomes in schizophrenia. Empirical support for this hypothesis comes primarily from small samples using retrospectively collected data. AIMS We tested this hypothesis, for the first time, using a population-based cohort. METHOD The Israeli Draft Board Registry, which contains measures of intellectual and behavioral functioning for the unselected population of 17-year-olds, was merged with the National Psychiatric Hospitalization Case Registry that contains data on all psychiatric hospitalizations. The database was used to identify adolescents assessed by the draft board at least 1 year prior to their first hospitalization for schizophrenia (n=996) or affective disorder (n=335). RESULTS Poorer social functioning and organizational ability prior to first admission were associated with more days per year in the hospital for the male schizophrenia group. There were no significant correlations between days per year in the hospital and any of the behavioral functioning measures for the affective group. Among females the higher the previous level of intellectual functioning the fewer the days per year in the hospital in both the schizophrenia group and affective groups. For males no such correlations were evident. The comparisons between patients who had one as opposed to more than one admission found that in both diagnostic groups female patients with one admission had higher pre-first hospitalization intellectual functioning. CONCLUSIONS Gender and disease specific premorbid deficits have may have differential prognostic value for outcomes in schizophrenia and affective disorders.

Abstract
Even though juvenile bipolar disorder (BD) is reported to be more treatment-resistant than adult BD, predictors of nonresponse are not well studied. The aim of this study was to address this issue in a naturalistic sample of bipolar children and adolescents with manic or mixed episodes treated under the condition of routine clinical practice. This study was comprised of 40 patients (19 females and 21 males; mean age, 14.2 years; SD = 3.3; range, 7-18) with a Diagnostic and Statistical Manual of Mental Disorders-fourth edition (DSM-IV) diagnosis of manic (n = 23) or mixed episodes (n = 17). The clinical characteristics of 20 patients considered to be treatment responders, according to the Clinical Global Impression-Improvement (CGI-I) scores, were compared to those of the 20 nonresponders. The effect of predictors on the probability of treatment nonresponse was analyzed using the multiple stepwise logistic regression, backward procedure. Demographic variables (mean age, gender ratio, socioeconomic status), as well as the inpatients-outpatients ratio (75% versus 65%), duration of the follow-up (10.5 +/- 2.5 months versus 9.6 +/- 3.2 months), index episode (manic versus mixed), and rates of pharmacologic hypomania did not differentiate the 2 groups. According to stepwise logistic regression, predictors of nonresponse were the presence of comorbidity with conduct disorder (odd ratio, 3.36; 95% CI, 2.20-4.52), attention deficit hyperactivity disorder (ADHD) (odd ratio, 2.30; CI, 1.24-3.26), and the baseline CGI Severity score (odd ratio, 2.31; CI, 1.33-3.29). It is relevant to point out that patient age at the onset of BD, and at the first visit, and comorbid anxiety disorders did not influence treatment response. Follow-up studies with a larger sample size with BD and/or externalizing disorders appropriately managed with different treatment options and/or combinations are warranted.

Abstract
Symptomatic and functional outcome and cognitive functioning were examined in adolescents experiencing their first episode of psychosis. The adolescents (n=69) were assessed and compared with adults (n=69), all presenting for treatment for the first time to a specialized Early Psychosis Program. Assessments were conducted at the initial presentation, and at 1- and 2-year follow-ups. Assessments included positive and negative symptoms, depression, number of relapses, substance use, cognitive functioning, age-appropriate productivity (employment or being in school) and quality of life. Adolescents showed both symptomatic and functional improvement over 2 years of optimal treatment. Positive and negative symptoms predicted outcome at 2 years. Compared with adults, the adolescents had similar clinical and functional outcomes but used more cannabis and had an increased number of relapses. These adolescents are doing relatively well following their first episode and reinforce the need to address cannabis use as an integral part of a comprehensive treatment program.

Abstract
UNLABELLED Childhood-onset schizophrenia is rare: its prevalence is about 50 times lower than the one observed in adulthood. It is also frequently unrecognized, notably because its clinical aspect varies with age. The authors report the case of a prepubertal girl who developed a typical clinical picture of schizophrenia (paranoid subtype) by age 9. CASE REPORT The patient was 10 years old when she was hospitalized for a relapse of a suspected childhood-onset schizophrenia. Several significant mental disorders were found in her family history: her mother was treated for mood disorders (including dysthymia and major depression with postpartum onset), while her father and a aunt exhibited schizophrenic disorders. In addition, prenatal and perinatal events (including probable prenatal maternal infection and obstetric complications) were reported by her mother. Demonstrable impairments were already present in her premorbid development: from the age of 3.5, she showed significant manifestations of behavioural inhibition and separation anxiety, severe difficulties in social adaptation, and language abnormalities (qualified by her general practitioner as selective mutism). At the age of 9, when her mother was hospitalized for a diabetes mellitus, she suddenly showed auditory and visual hallucinations associated with delusions. Their content included filiation, somatic, and persecutory themes. Grossly disorganized behaviour (and more particularly catatonic motor behaviours including catatonic rigidity and negativism and bizarre postures) was also observed. Negative symptoms (eg anhedonia, affective flattening, and alogia) were noted. Her IQ scores were 74 in the verbal subtests and 53 in the performance subtests. Because the diagnostic of childhood-onset schizophrenia was suspected, a neuroleptic treatment, haloperidol 3 mg/day, was tried. After a partial remission during a few months period (characterized by a decrease in delusions, anxiety and sleep difficulties), she showed a relapse leading to her hospitalization. At the time of her admission, she showed severe manifestations of separation anxiety including agitation, anger, crying, and insomnia, for which she received a short-lived treatment by lorazepam. When sedation was obtained, the clinical picture proved similar to the one previously observed: hallucinations, delusions, grossly disorganized behaviour, and thought disorder were noted. As soon as the diagnostic of childhood-onset schizophrenia was confirmed, she was administered a new antipsychotic agent, amisulpride, at dose of 600 mg/day. This treatment was going on during several weeks with no significant clinical effect. Because the early onset of the disorder, the family history of schizophrenia, and the lack of effectiveness of the two previously administered antipsychotic agents, a treatment with clozapine was started at the dose of 12,5 mg/day. From the outset of this treatment, clinically significant reductions in hallucinations and disorganized behaviours were noted. Dose was then progressively increased until 200 mg/day, resulting in significant improvement in cognitive and motor functioning. The patient is now in an educational institute. Her adaptation is considered satisfactory, in spite of regular exacerbations of delusions in response to stressful life events. Treatment with clozapine is going on, without any significant undesirable clinical effects. DISCUSSION If an abrupt onset is rarely observed in prepubertal children, all the authors report that patients with very early onset schizophrenia show to have demonstrable impairments in their premorbid language as well as in their motor and social development. In addition, several studies suggest that more pronounced early developmental abnormalities are usually associated with a poor outcome in schizophrenia. The clinical picture also agrees with recent studies showing that in children paranoid subtype is as frequent as seen in adult disorders. If genetic factors play a significant role in the pathogenesis of schizophrenia, the notion that such factors may be more salient in very early onset and more severe cases is now usually accepted. However, a number of environmental factors, including prenatal maternal infections and perinatal complications, may also be implicated in the pathogenesis of schizophrenia, in addition to genetic factors. Because a significant relationship between stressful life events and exacerbations in positive symptoms was found in the case reported, the authors examine the role of such stress factors in the pathogenesis of schizophrenia and in the course of illness. A brief review of studies that have examined the effects of antipsychotic agents in children with schizophrenia underscores the paucity of data available to guide clinicians in this area. However, these data suggest that children who receive conventional neuroleptics experience significant adverse effects, primarily sedation and extrapyramidal symptoms. In addition, they suggest that new antipsychotic agents, such as clozapine, may be more effective than conventional neuroleptics, particularly in negative symptoms. Lastly, the authors emphasize the poor outcome usually reported in childhood-onset schizophrenia, highlighting the need of a long-term pharmacological and behavioural treatment. CONCLUSION This case report, such as others, supports the hypo-thesis that there is a clinical continuity between early and later onset schizophrenia. It also suggests that very early onset schizophrenia is a more severe form of the disorder and may be secondary to greater familial vulnerability. Consequently, systematic studies of these patients may be particularly informative and may provide important informations for understanding the etiologic processes involved in the pathogenesis of schizophrenia.

Abstract
Our objective was to evaluate the scope and clinical correlates of psychotic phenomena in psychiatrically referred children and adolescents. Subjects were 1657 psychiatrically referred youth (mean age = 10.9 years) evaluated from 1991 to 2002. DSM-III-R diagnoses were obtained through maternal report by using the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Epidemiologic Version. Childhood-onset psychosis was defined by the presence of delusions or hallucinations. Childhood-onset psychosis was identified in 8% of psychiatrically referred youth. It was associated with a chronic course and high levels of impairment. Comorbidity with disruptive, mood, and anxiety disorders was very severe, with only one of the 132 identified youth with psychosis not having at least one comorbidity. In conclusion, childhood-onset psychosis in referred youth is common and highly morbid. It remains an important topic of research deserving full clinical and scientific attention.

Impaired psychosocial functioning has been well documented in bipolar disorder, although there is little information linking premorbid adjustment with adult functional outcome. Childhood and adolescent functioning in school, peer relations, and personal interests was evaluated by standardized interviews with 56 adult-onset DSM-IV bipolar I (N = 46), II (N = 7), or not otherwise specified (N = 3) patients, with collaboration by collateral historians, and assessed relative to current work functioning and overall illness features. Poor childhood or adolescent adjustment was associated with subsequent alcohol or drug abuse or dependence (p <.05), insidious onset of bipolar disorder (p <.02), and increased suicide attempts (p <.02). Poor adjustment in childhood was related to the lifetime development of rapid cycling. Poor premorbid adjustment may be linked with the potential to develop substance abuse comorbidity and an increased risk for suicide attempts and rapid cycling in bipolar patients. The prognostic significance of maladaptive childhood or adolescent behaviors may bear directly on clinical components of outcome in bipolar disorder.

Abstract
BACKGROUND In the past 10 years, there has been increased research on childhood-onset schizophrenia and clear advances have been achieved. METHOD This annotation reviews the recent clinical and treatment literature on childhood-onset schizophrenia. RESULTS There is now strong evidence that the syndrome of childhood-onset schizophrenia exists and there are several similarities between childhood- and later-onset schizophrenia. Schizophrenia in youth can be reliably diagnosed using the same criteria employed with adults, and childhood-onset schizophrenia is predictive of schizophrenia or schizophrenia spectrum disorders in adulthood. Data is accumulating to guide pharmacological treatment strategies, and practice parameters have been developed to guide clinical care. CONCLUSIONS Despite significant advances, there remains an urgent need for additional research on treatment and service delivery strategies. Promising work with adults highlights the importance of attending to psychosocial as well as pharmacologic treatment strategies, and the potential value of preventive interventions.

Abstract
This practice parameter reviews the literature on the assessment and treatment of children and adolescents with schizophrenia. Recommendations are based on the limited research available, the adult literature, and clinical experience. Early-onset schizophrenia is diagnosed using the same criteria as in adults, and it appears to be continuous with the adult form of the disorder. Noted characteristics of youth with schizophrenia include predominance in males, high rates of premorbid abnormalities, and often poor outcome. Differential diagnosis includes psychotic mood disorders, developmental disorders, organic conditions, and nonpsychotic emotional/behavioral disorders. Treatment strategies incorporate antipsychotic medications with psychoeducational, psychotherapeutic, and social and educational support programs. The advent of atypical antipsychotic agents has enhanced the potential for effective treatment.

Abstract
OBJECTIVE The Psychological Assistance Service (PAS) opened in Newcastle, New South Wales in 1997 as a clinical service for the assessment and treatment of young people at high risk of psychosis and those experiencing a first psychotic episode. The aim of this paper is to describe the assessment protocol of PAS, which is strongly influenced by the neurodevelopmental perspective on early onset psychosis. METHOD The systematic assessment of patients referred to PAS using a protocol over a 2 week period is described. The protocol includes a narrative history, structured diagnostic interview, quantitative assessment of symptoms and other clinical features, a neurological examination and comprehensive neuropsychological test battery. RESULTS The clinic has received over 250 referrals in a 2 year period and accepted 116 patients for a full assessment, of whom 60 were deemed to be 'at-risk' of psychosis and 56 were experiencing their first psychotic episode. Both groups were similar with respect to gender and there were minor age differences. The first-episode group experienced more reality distortion, schizotypal and negative symptoms. While both groups showed some neuropsychological and neurological impairment, there were no statistically significant differences between the groups on these variables except for a test of executive functioning in which the first-episode group was more impaired than the 'at-risk' group. A low rate of conversion to psychosis occurred in the 'at-risk' group. CONCLUSIONS The minor differences between the two groups may have been related to relatively small sample sizes, although some similarities between the groups were to be expected. The low rate of conversion to psychosis in the 'at-risk' group is discussed. Further analyses using larger samples are necessary to determine the validity of the various 'at-risk' categories and this will involve following a sufficiently large sample over an adequate time. The most efficient way of doing this would be to pool data across centres with comparable early intervention programs.

Abstract
OBJECTIVE To review the diagnostic evolution and predictive variables of diagnosis and outcome in first-episode psychosis in adolescents (age 13-19 years) and adults. METHOD Literature was reviewed through MEDLINE, Psycinfo, and PubMed, and supplemented by selected bibliographies. RESULTS First-episode psychosis in the adolescent population has greater diagnostic instability than in adults. We identified trends in the predictive variables of diagnosis and outcome: 1) Premorbid adjustment (that is, personality) in adolescents and Global Assessment of Functioning (GAF) both before and after first-episode psychosis in adolescents and adults are the best predictors of diagnosis; 2) GAF (before and after) is the best predictor of outcome in both adolescents and adults. CONCLUSION Adolescent-onset psychosis appears to be in continuity with adult-onset psychosis. The greater diagnostic instability in adolescents and the absence of significant data on predictive variables suggest a need for specialized and continuous care and research in the adolescent population.

Abstract
This study reports on the long-term course of 11 patients (6 girls, 5 boys) with childhood onset schizophrenia (COS, age at onset < 10 years). Patients were examined twice (mean follow-up period 38 years after onset). The premorbid development is assessed in terms of the Modified Premorbid Adjustment Scale (M-PAS) and additionally described by distinct psychopathological categories. The psychopathology at the onset of psychosis and at the second follow-up examination was assessed by categorical application of the Positive and Negative Syndrome Scale (PANSS). The outcome was rated with the Disability Assessment Score (DAS). The course of psychotic episodes and intervals between them is presented according to DSM-IV subtype classifications. Ten of 11 patients presented premorbid developmental peculiarities that were not adequately covered by the M-PAS subscales. Whereas in the 4 patients with acute onset of psychosis the positive PANSS-type was predominant, in the 7 patients with an insidious onset the negative PANSS-type prevailed. The nature of the diagnostic subtypes varied markedly across the course of the illness. In case of a continuous predominant catatonic symptomatology the outcome was poor. Detailed case descriptions help to illuminate the heterogeneous psychopathology of COS. Various temporary premorbid behavioral peculiarities were precursors of COS. A differentiation between premorbid and prodromal signs proved to be arbitrary. Our results contradict the assumption that COS is characterized only by a negative symptomatology.

Abstract
OBJECTIVES To examine the clinical features and diagnostic stability of early-onset psychotic disorders. METHODS These data are from a two-year longitudinal prospective study of youth with psychotic disorders. Standardized diagnostic assessments are administered at baseline and at one and two-year's follow-up. RESULTS Fifty-one subjects have been recruited to date; 18 with schizophrenia, 14 with bipolar disorder, 7 with schizoaffective disorder, 1 with an organic psychosis, and 11 subjects whose symptoms where either questionable and/or did not meet diagnostic criteria for another disorder (classified as psychosis nos). Thirty-nine subjects were reassessed at year one, twenty-four at year two. Three subjects have been lost to follow-up. The study diagnosis was the same as the first onset diagnosis (prior to entering the study) in 50% of subjects. Over the two-year period of the study, the diagnosis remained unchanged in over 90% of subjects. Subjects with schizophrenia had higher ratings of premorbid impairment, including social withdrawal and dysfunctional peer relationships, than those with bipolar disorder. At the one-year follow-up, subjects with schizophrenia and schizoaffective disorder had significantly higher rates of delusions, bizarre behavior, and negative symptoms than those with bipolar disorder. Subjects with bipolar disorder tended to have cyclical courses, whereas those with schizophrenia and schizoaffective disorder were often chronically impaired. Subjects with psychosis nos had higher rates of dissociative symptoms and histories of child maltreatment. CONCLUSIONS Early-onset psychotic disorders can be reliably diagnosed using standardized assessments and are stable over a two-year period. Compared to bipolar disorder, schizophrenia is associated with a poorer premorbid history, and persistent positive and negative symptoms.

Abstract
The symptom dimensions of childhood-onset schizophrenia (COS) are described by focussing on the clinical features of 44 patients at onset of illness during the first episode and at follow-up investigation 42 years after onset. All subjects were re-diagnosed according to DSM IV. The symptomatology was evaluated with the Positive and Negative Symptom Scale (PANSS) at onset and at follow-up. Two principal component factor analyses with varimax-rotation were applied to the complete items set of the PANSS. The frequencies of positive, negative, and global symptoms were compared longitudinally in an ANOVA-repeated measures design. The factor analysis revealed 5 orthogonal symptom dimensions (factors) at onset of psychosis: Cognition, social withdrawal, antisocial behaviour, excitement, and reality distortion. At follow-up a five-factor solution was found, too, but different dimensions emerged: a positive, negative, excitement, cognitive, and anxiety/depression component which fits to the 5-factor model of White et al. (1997). The first psychotic episode of EOS is accompanied with more unspecific symptoms such as social withdrawal and antisocial behavior. In the later stages of (COS) the structure of symptom dimensions changes to that known from adult-onset schizophrenia (AOS). The results indicate that COS and AOS are comparable nosological entities and that more than 3 dimensions are required to describe the relevant clinical symptom structure. Positive and global symptoms decreased significantly during the course of illness. The frequencies of negative symptoms did not change which demonstrates their disabling impact.

Abstract
INTRODUCTION We present the results of a 42 year long-term follow-up of 44 patients (19 males, 25 females) with childhood-onset schizophrenia (COS, age at onset: 7-14 years) who could be traced for a second follow-up examination 27 years after the first follow-up. METHOD Data from interviews, clinical records, premorbid and social disability assessments were evaluated for statistical analyses. The symptomatology observed during the whole course of illness was rediagnosed by DSM-IV criteria. RESULTS The paranoid, catatonic, and schizoaffectives subtypes appeared most frequently. There have been no gender differences in age of first psychiatric symptoms (AFS), AFPS, and age of first hospitalization. Kaplan-Meier's survival-analysis carried out for AFPS with sex as the grouping factor revealed that the cumulative prevalence appears to be earlier in females (between 7 and 15 years) than in males (between 10 and 18 years). Of the 44 patients 50 % had a continuing severe course. Patients with onset before 12 years of age were characterized by a chronic/insidious onset, marked premorbid abnormalities, and by a poorer remission. Premorbid features of social withdrawal and reluctance indicated a risk for social disability within the later course. CONCLUSION COS, as a rare but severe variant of schizophrenia, frequently develops from premorbid social maladaptation to an insidious onset but is subsequently followed by a transition to a course and outcome not distinguishable from that of adult-onset schizophrenia.
