Abstract
OBJECTIVE Recently, there has been a resurgence of interest in the relationship between infections and psychopathology, given the increasing data on the neurotropism and neurological/psychiatric morbidity of the SARS-COV2 virus, responsible for the current worldwide pandemic. Although the majority of observations were those obtained in mood and schizophrenic disorders, a few data are also available on the presence of bacterial or viral infections in patients suffering from obsessive-compulsive disorder (OCD). Therefore, given the limited information, the present paper aimed at reviewing the most updated evidence of infections in neuropsychiatric disorders and their possible mechanisms of actions, with a narrow focus on microbes in OCD. METHOD This paper is a narrative review. The databases of PubMed, Scopus, Embase, PsycINFO and Google Scholar were accessed to research and collect English language papers published between 1 January 1980 and 31 December 2021. The data on PANDAS/PANS and those observed during severe brain infections were excluded. RESULTS Several pathogens have been associated with an increased risk to develop a broad spectrum of neuropsychiatric conditions, such as schizophrenia, mood disorders, autism, attention-deficit/hyperactivity disorder, anorexia nervosa, and post-traumatic stress disorder. Some evidence supported a possible role of infections also in the pathophysiology of OCD. Infections from Herpes simplex virus 1, Borna disease virus, Group A-Beta Hemolytic Streptococcus, Borrelia spp., and Toxoplasma gondii were actually found in patients with OCD. Although different mechanisms have been hypothesized, all would converge to trigger functional/structural alterations of specific circuits or immune processes, with cascade dysfunctions of several other systems. CONCLUSIONS Based on the current evidence, a possible contribution of different types of microbes has been proposed for different neuropsychiatric disorders including OCD. However, the currently available literature is meager and heterogeneous in terms of sample characteristics and methods used. Therefore, further studies are needed to better understand the impact of infectious agents in neuropsychiatric disorders. Our opinion is that deeper insights in this field might contribute to a better definition of biological underpinnings of specific clinical pictures, as well as to promote psychiatric precision medicine, with treatments based on altered pathological pathways of single patients. This might be particularly relevant in OCD, a disorder with a high proportion of patients who are resistant or do not respond to conventional therapeutic strategies.

Abstract
Sydenham's chorea is an autoimmune chorea emerging after a group A beta-hemolytic streptococcal (GABHS) infection, i.e. a rheumatic chorea with or without the presence of carditis or arthritis. The disorder, defined by the presence of chorea, is also associated with cognitive and behavioral symptoms, including emotional lability, anxiety, depressive and obsessive-compulsive symptoms. The authors review the pathophysiology, clinical characteristics, and available evidence on therapeutic strategies, the latter including the secondary prevention of GABHS infections, reduction of chorea, and immune modulation. Sydenham's chorea has been regarded as a model for pediatric autoimmune neuropsychiatric disorders, however, the field is marked by conflicting results and controversies. Regarding therapeutics, there are limited high-quality interventional studies and the selection of treatment strategy often relies on the clinician's experience. A serial treatment algorithm is presented based upon the severity of clinical presentation and response to symptomatic pharmacotherapy.

Abstract
Current knowledge on the general somatic health and causes of death in Tourette syndrome and chronic tic disorder is very limited. Here, we review the available literature on the topic, while highlighting strengths and weaknesses of the studies conducted to date. These previous works have suggested associations between Tourette syndrome and chronic tic disorder and a range of health conditions, including autoimmune disorders, common allergies and respiratory diseases, sleep difficulties, and metabolic and cardiovascular outcomes. Additionally, the risk of mortality in tic disorders might be higher than that of the general population, but specific causes of death have rarely been studied, except for substance use-related deaths and suicide, which are significantly higher in individuals with Tourette syndrome and chronic tic disorder. Many of these emerging findings require replication and extension but, taken together, they suggest that that it might be sensible to monitor the general health and suicide risk of individuals with Tourette syndrome or chronic tic disorder across the lifespan. We suggest further avenues for research on this topic.

Abstract
The association between obsessive-compulsive disorder (OCD) and Tourette's/chronic tic disorders (TD/CTD) with autoimmune diseases (ADs) is uncertain. In this nationwide study, we sought to clarify the patterns of comorbidity and familial clustering of a broad range of ADs in individuals with OCD, individuals with TD/CTD and their biological relatives. From a birth cohort of 7 465 455 individuals born in Sweden between 1940 and 2007, we identified 30 082 OCD and 7279 TD/CTD cases in the National Patient Register and followed them up to 31 December 2013. The risk of 40 ADs was evaluated in individuals with OCD, individuals with TD/CTD and their first- (siblings, mothers, fathers), second- (half siblings) and third-degree (cousins) relatives, compared with population controls. Individuals with OCD and TD/CTD had increased comorbidity with any AD (43% and 36%, respectively) and many individual ADs. The risk of any AD and several individual ADs was consistently higher among first-degree relatives than among second- and third-degree relatives of OCD and TD/CTD probands. The risk of ADs was very similar in mothers, fathers and siblings of OCD probands, whereas it tended to be higher in mothers and fathers of TD/CTD probands (compared with siblings). The results suggest a familial link between ADs in general (that is, not limited to Streptococcus-related conditions) and both OCD and TD/CTD. Additional mother-specific factors, such as the placental transmission of antibodies, cannot be fully ruled out, particularly in TD/CTD.

Abstract
Pediatric movement disorders may present with psychiatric symptoms at many points during the course of the disease. For the relatively common pediatric movement disorder, Tourette syndrome, psychiatric comorbidities are well-described and treatment is well-studied. Managing these comorbidities may be more effective than improving the movements themselves. For more uncommon movement disorders, such as juvenile-onset Huntington disease, treatment of psychiatric comorbidities is not well-characterized, and best-practice recommendations are not available. For the least common movement disorders, such as childhood neurodegeneration with brain iron accumulation, psychiatric features may be nonspecific so that underlying diagnosis may be apparent only after recognition of other symptoms. However, psychiatric medication, psychotherapy, and psychosocial support for these disorders may prove helpful to many children and adolescents.

Abstract
AIM Sydenham's chorea is a post-streptococcal, autoimmune, neuropsychiatric movement disorder. Sydenham's chorea is a major criterion for diagnosis of acute rheumatic fever with the implication of potential long-term sequelae including cardiac complications. It is well established that there is psychiatric comorbidity in Sydenham's chorea, but there are variations in the literature regarding the nature and prevalence of psychiatric diagnoses associated with Sydenham's chorea. The aim of this review was to systematically evaluate the evidence for psychiatric symptoms presenting with Sydenham's chorea. Knowledge of comorbid psychiatric symptomatology will support early diagnosis and treatment, leading to improved long-term outcomes for children with Sydenham's chorea. METHOD The study used a systematic search strategy, using MEDLINE, MEDLINE in Process, EMBASE, and The Cochrane Library. Abstracts were screened to identify relevant papers which were then assessed further. Eligible papers were summarized. RESULTS A total of 1429 abstracts of relevant studies were found, and 49 papers reporting neuropsychiatric symptoms in Sydenham's chorea were summarized. Obsessive-compulsive disorder was the most commonly studied, and hence reported, neuropsychiatric symptom in children with Sydenham's chorea. The studies analysed used a variety of tools to identify affected children and used different methods for analysing results. Attention-deficit-hyperactivity disorder, affective disorders, tic disorders, executive function disturbances, and psychotic features were also reported as comorbidities. INTERPRETATION There is good evidence of neuropsychiatric comorbidities in Sydenham's chorea. In countries with a high prevalence of rheumatic fever, the early recognition of salient cognitive and psychiatric symptoms may aid in the management of Sydenham's chorea.

Abstract
INTRODUCTION Chorea is well described in a group of patients with Systemic Lupus Erythematosus (SLE). There is less information, however, on other movement disorders as well as non-motor neuropsychiatric features such as obsessive-compulsive symptoms (OCS), executive dysfunction and attention deficit and hyperactivity disorder (ADHD) in subjects with SLE. METHODS Fifty-four subjects with SLE underwent a battery of neuropsychiatric tests that included the Mini Mental State Examination, the Montreal Cognitive Assessment, the Frontal Assessment Battery (FAB), the FAS verbal and the categorical (animals) semantic fluency tests, the Obsessive and Compulsive Inventory - Revised, the Yale-Brown Obsessive and Compulsive Scale and Beck's Anxiety and Depression Scales. ADHD was diagnosed according to DSM-IV criteria. SLE disease activity and cumulative damage were evaluated according to the modified SLE Disease Activity Index 2000 (mSLEDAI-2K) and the SLICC/ACR, respectively. RESULTS Six (11.1%) and 33 (61.1%) patients had cognitive impairment according to the MMSE and MoCA, respectively. Eleven (20.4%) had abnormal FAB scores, and 5 (9.3%) had lower semantic fluency scores than expected. The overall frequency of cognitive dysfunction was 72.2% (39 patients) and of neuropsychiatric SLE was 77.8% (42 patients). Two patients (3.7%) had movement disorders. Fifteen (27.8%) had OCS and 17 (31.5%) met diagnostic criteria for ADHD. ADHD and OCS correlated with higher disease activity, p=0.003 and 0.006, respectively. Higher cumulative damage correlated with lower FAB scores (p 0.026). CONCLUSIONS Executive dysfunction, ADHD, OCS, and movement disorders are common in SLE. Our finding suggests that there is frequent basal ganglia dysfunction in SLE.

Abstract
BACKGROUND While a great amount of attention has been paid to early-onset obsessive-compulsive disorder (OCD), there is a dearth of studies on patients showing OCD for the first time at later stages of life. In this study, we aimed at determining possible risk factors/correlates for OCD onset at or after age 40, here termed late-onset OCD. METHOD A series of models including several potential variables associated with late onset OCD were tested using a monolayer neural network. To this regard, data from the Brazilian Research Consortium of Obsessive-Compulsive Spectrum Disorders (CTOC) (n = 1001) was employed. For the purposes of this study, we considered a diagnosis of late onset OCD to be present whenever distress and interference associated with OCD symptoms emerged at or after age 40. Different nested models were compared through the Akaike Criteria keeping the variables with p value ≤0.05. RESULTS Late-onset OCD occurred in 8.6% of the sample. A model including female sex, a history of chronic (>10 years) subclinical obsessive-compulsive symptoms, the co-occurrence of posttraumatic stress disorder (PTSD) after age 40, and a history of recent pregnancy in self or significant others was able to explain a sizeable proportion of late-onset OCD. The general performance of this model, represented by the Maximum Likelihood R2, was 29.4%. CONCLUSION Our results suggest that late-onset OCD is more likely to occur in females, in individuals with long periods of subclinical obsessive-compulsive symptoms, and in association with a major traumatic event occurring after age 40 and a history of recent pregnancy in self or in significant others.

Abstract
The etiopathogenesis of obsessive-compulsive disorder (OCD) remains elusive. Clinical observation of the elevated frequency of obsessive-compulsive symptoms in patients with rheumatic fever, a post-streptococcal autoimmune disease, prompted the study of immune parameters in OCD. Anti-basal ganglia antibodies have been described in a subset of OCD patients. The assessment of circulating cytokines and immune cells confirmed unequivocal changes in at least some patients, although it is difficult to establish a particular immune profile in OCD. Several factors, including the use of psychotropic drugs and the presence of comorbid conditions, seem to influence these immune parameters.

Abstract
AIM The cognitive and psychiatric aspects of adult movement disorders are well established, but specific behavioural profiles for paediatric movement disorders have not been delineated. Knowledge of non-motor phenotypes may guide treatment and determine which symptoms are suggestive of a specific movement disorder and which indicate medication effects. METHOD The goal of this review is to outline the known cognitive and psychiatric symptoms associated with paediatric movement disorders. We used a systematic approach, via PubMed, and reviewed over 400 abstracts of studies of selected disorders, of which 88 papers reporting paediatric non-motor symptoms are summarized. RESULTS Obsessive-compulsive disorder was manifest in children with paediatric autoimmune neuropsychiatric disorders associated with streptococcal infections and Sydenham chorea. Children with opsoclonus-myoclonus syndrome had, for the most part, cognitive and behavioural problems, and attention-deficit-hyperactivity disorder was reported as a major comorbidity in Tourette syndrome, stereotypies, and restless legs syndrome. Symptoms of depression and anxiety were more frequent in individuals with idiopathic dystonia. Affective disorders were suggestive of Wilson disease. Cognitive decline was common in children with juvenile Huntington disease. A limitation of this review was the lack of systematic assessment in paediatric movement disorders for evaluation and uniform definitions. INTERPRETATION Although the literature in non-motor phenomena is still emerging, recognition of salient cognitive and psychiatric phenomena may facilitate management of paediatric movement disorders.

Abstract
Obsessive-compulsive disorder (OCD) is a clinical syndrome whose hallmarks are
excessive, anxiety-evoking thoughts and compulsive behaviors that are generally
recognized as unreasonable, but which cause significant distress and impairment.
When these are the exclusive symptoms, they constitute uncomplicated OCD. OCD
may also occur in the context of other neuropsychiatric disorders, most commonly
other anxiety and mood disorders. The question remains as to whether these
combinations of disorders should be regarded as independent, cooccurring
disorders or as different manifestations of an incompletely understood
constellation of OCD spectrum disorders with a common etiology. Additional
considerations are given here to two potential etiology-based subgroups: (i) an
environmentally based group in which OCD occurs following apparent causal events
such as streptococcal infections, brain injury, or atypical neuroleptic
treatment; and (ii) a genomically based group in which OCD is related to
chromosomal anomalies or specific genes. Considering the status of current
research, the concept of OCD and OCD-related spectrum conditions seems fluid in
2010, and in need of ongoing reappraisal.
