متن کاملAltered striatal functional connectivity in subjects with an at-risk mental state for psychosis.
Recent functional imaging work in individuals experiencing an at-risk mental state (ARMS) for psychosis has implicated dorsal striatal abnormalities in the emergence of psychotic symptoms, contrasting with earlier findings implicating the ventral striatum. Our aims here were to characterize putative dorsal and ventral striatal circuit-level abnormalities in ARMS individuals using resting-state ...
متن کاملEthnicity and baseline symptomatology in patients with an At Risk Mental State for psychosis.
BACKGROUND Ethnicity has been associated with different incidence rates and different symptom profiles in young patients with psychotic-like disorders. No studies so far have examined the effect of ethnicity on symptoms in people with an At Risk Mental State (ARMS). METHOD In this cross-sectional study, we analysed the relationship between ethnicity and baseline data on the severity of psycho...
