The considerable variation in the spatial distribution of cortical thickness changes has been used to parse heterogeneity in schizophrenia. We aimed to recover a ‘cortical impoverishment’ subgroup with widespread cortical thinning. We applied hierarchical cluster analysis to cortical thickness data of three datasets in different stages of psychosis and studied the cognitive, functional, neurochemical, language and symptom profiles of the observed subgroups. Our consensus-based clustering procedure consistently produced a subgroup characterized by significantly lower cortical thickness. This ‘cortical impoverishment’ subgroup was associated with a higher symptom burden in a clinically stable sample and higher glutamate levels with language impairments in …

Psychotic disorders can be variable in clinical presentation, and there may be differences by sex. The objective of this thesis was to explore sex differences in the clinical presentation of early psychosis in the context of primary care. Our systematic review and meta-analysis found that men experienced more negative symptoms and had a higher prevalence of substance use issues, whereas women experienced more depressive symptoms and had higher functioning. Our electronic medical record analysis from primary care found that positive symptoms and substance use were less prevalent in the medical records of women. We also found that visits by women …
