CONTEXT AND OBJECTIVE: Autism spectrum disorders (ASDs) include autistic disorder, Asperger's disorder and pervasive developmental disorder. The manifestations of ASDs can have an important impact on learning and social functioning that may persist during adulthood. The aim here was to summarize the evidence from Cochrane systematic reviews on interventions for ASDs. DESIGN AND SETTING: Review of systematic reviews, conducted within the Discipline of Evidence-Based Medicine, Escola Paulista de Medicina, Universidade Federal de São Paulo...

Schizotypal personality disorder (SPD) is characterised by thought disorders, experiences of illusions, obsessive ruminations, bizarre or eccentric behaviour, cognitive problems and deficits in social functioning - symptoms that SPD shares with schizophrenia. Efforts have been undertaken to investigate the relationship between these conditions regarding genetics, pathophysiology, and phenomenology. However, treatment of SPD with antipsychotics has received less scientific attention. Embase and PubMed databases were searched using all known generic names of antipsychotics as search terms in combination with the following diagnostic terms: latent schizophrenia, schizotypal disorder, latent type schizophrenia, or SPD...

Isela is an 11-year-old Mexican-American girl with mild intellectual disability. During a vacation with her family, she went swimming with dolphins. A few days later, Isela awoke at night with laughing spells; during the day, she was pacing, aggressive, and had a decline in self-care and communication skills. Her parents attributed the symptoms to the dolphins. She was evaluated by a pediatric neurologist. The sleep-deprived electroencephalogram, brain magnetic resonance imaging, lumbar puncture, and thyroid function tests were normal...

Clinical studies indicate that about one-third of pregnant women with psychotic symptoms are exposed to either typical or atypical antipsychotic drugs (APDs). Reports on prenatal subject/model are lacking hence, the present study was undertaken to investigate the effect of prenatal exposure to risperidone (RIS) on the fetal hippocampus, and their related functional changes in young rat offspring. In this study, pregnant Wistar rats were exposed to equivalent therapeutic doses of RIS at 0.8mg/kg, 1.0mg/kg, and 2...

Increasing evidence suggests that altered immune functions are related to the pathophysiology of schizophrenia. Relatively little information is available on Toll-like receptors (TLRs), which are implicated in the recognition of molecular patterns associated with pathogens and internal cellular damage signals. By using immunophenotyping and flow cytometry, we investigated TLRs in CD14+ monocytes, CD4+CD25+Foxp3+ regulatory T cells (Treg), and CD3+CD4+CD25+ activated T cells (Tact) in 35 drug-naïve patients with schizophrenia before and after an 8-week period of antipsychotic treatment with risperidone or olanzapine...

There are currently no effective pharmacological agents available to stop or prevent the progression of Huntington's disease (HD), a rare hereditary neurodegenerative disorder. In addition to psychiatric symptoms and cognitive impairments, HD causes progressive motor disturbances, in particular choreiform movements, which are characterized by unwanted contractions of the facial muscles, trunk and extremities. Management of choreiform movements is usually advised if chorea interferes with daily functioning, causes social isolation, gait instability, falls, or physical injury...

The "glutamate hypothesis of schizophrenia" has changed attitudes in the development of new medications. This study aimed to evaluate the effects of 20mg of memantine per day (as a NMDA receptor antagonist) added to risperidone among male patients with schizophrenia. In a randomized placebo-controlled, double-blind clinical trial, 46 adult male patients with schizophrenia were evaluated in both intervention and control groups at weeks 0, 6 and 12. The positive and negative symptoms scale and the mini mental status examination were used to assess positive, negative and cognitive symptoms and general psychopathology...

INTRODUCTION: Adolescence is a unique phase of the human developmental process. In adolescents, psychotropic medications may have different efficacy and tolerance profiles compared to those at other stages of the lifespan. Mood stabilizers are a complex pharmacological category including lithium, some anticonvulsants, and some second generation antipsychotics. Focusing on this class of pharmacological agents, we aim to answer the following questions: in which indications and according to which modalities should mood stabilizers be prescribed during adolescence? METHODS: Information was sought from the websites of the French Haute Autorité de santé (HAS) and Agence nationale de sécurité du médicament et des produits de santé (ANSM), the American Food and Drug Administration (FDA) and the British National Institute for Health and Clinical Excellence (NICE)...

Thioredoxin is a serum antioxidant that has been investigated in the etiology of schizophrenia. The aim of this study is investigating the relationship between serum thioredoxin levels and cognitive functions in acute psychotic episode and remission state patients with schizophrenia; and examining whether there were differences between patients using clozapine and other atypical antipsychotics; including risperidone, olanzapine and amisulpride. This research was performed in schizophrenia patients hospitalized with acute psychotic episode (n=57), reevaluated patients after the initiation of treatment (mean 16 weeks) (n=46), and healthy controls (n=41)...

Breast milk is considered the best source of nutrients and provides much better protection than immune modified milk. However, the postpartum period is a phase of increased risk for all women to experience psychiatric symptoms and recurrences or new episodes of bipolar disorder (BD), especially in those who have discontinued treatment. This is a systematic review of the risks and benefits of mood stabilizers and antipsychotics during breastfeeding as they relate to the health and well-being of mothers and their infants...

BACKGROUND: Schizotypal personality disorder (SPD) is a schizophrenia-spectrum disorder characterized by odd or bizarre behavior, strange speech, magical thinking, unusual perceptual experiences, and social anhedonia. Schizophrenia proper has been associated with anomalies in dopaminergic neurotransmission and deficits in neurophysiological markers of self-monitoring, such as low amplitude in cognitive event-related brain potentials (ERPs) like the error-related negativity (ERN), and the error positivity (Pe)...

BACKGROUND: Recently, long-acting injection (LAI) of second-generation antipsychotics has become a valuable strategy for the treatment of schizophrenia. However, few studies have compared the effects of different LAI antipsychotics on cognitive functions so far. The present study aimed to compare the influence of risperidone LAIs (RLAI) and paliperidone palmitate LAIs (PP) on cognitive function in outpatients with schizophrenia. METHODS: In this 6-month, open-label, randomized, and controlled study, 30 patients with schizophrenia who were treated with RLAIs were randomly allocated to the RLAI-continued group or the PP group...
