Background: There is no study to date that has examined the association between history of abuse and adaptive functioning deficits in youth with co-occurring and psychotic disorders or mood disorders. Method: This study used a retrospective chart review of 98 youth under the age of 18 (Mean age = 16.06 years) with co-occurring intellectual…

Objective: The hippocampus has been implicated in the pathogenesis of schizophrenia, and hippocampal volume deficits have been a consistently reported abnormality, but the subregional specificity of the deficits remains unknown. The authors explored the nature and developmental trajectory of subregional shape abnormalities of the hippocampus in…

Objective: To assess neurocognitive outcomes following antipsychotic intervention in youth enrolled in the National Institute of Mental Health (NIMH)-funded Treatment of Early-Onset Schizophrenia Spectrum Disorders (TEOSS). Method: Neurocognitive functioning of youth (ages 8 to 19 years) with schizophrenia or schizoaffective disorder was evaluated…

Objective: This study examines relations between the severity of specific symptoms of schizophrenia spectrum disorder (SSD) and severity of the three defining symptom domains of autism spectrum disorder (ASD) in children with ASD (N = 147) and child psychiatry outpatient referrals (Controls; N = 339). Method: Participants were subdivided into four…

In the last decade there has been an exponential increase in studies on neurobiological measures in childhood-onset schizophrenia (COS). There seems to be a consensus that structural changes in COS are more marked than in adolescence-onset (AdOS) or adult-onset schizophrenia (AOS). Atrophy of total brain volume is progressive throughout the course…

Objective: Clozapine is a unique atypical antipsychotic with superior efficacy in treatment-resistant schizophrenia. Plasma concentration of clozapine and its major metabolite N-desmethylclozapine (NDMC) as well as the ratio of NDMC to clozapine have been reported to be predictors of clozapine response. Here we evaluate these as well as other…

Objective: This national study examined the practices and perceptions of smoking cessation activities among child and adolescent psychiatrists.

This paper reports on two children diagnosed as having co-occurring autistic disorder, schizophrenia-like psychosis, and Tourette syndrome, and two autistic adults who had tics and episodes of schizophrenia-like psychosis. (JDD)

Background: Childhood onset schizophrenia (COS) is a rare disorder. Comparative data on the effect of differential age of onset on clinical profile in schizophrenia are very few. Method: Subjects with COS (n = 15), adolescence onset schizophrenia (AdOS, n = 20) and adulthood onset schizophrenia (AOS, n = 20) were compared on socio-demographic,…
