What is already known on this topic?

People with a first-episode of psychosis (FEP) show cognitive impairments relative to healthy controls that are present at the onset of psychotic disorder.1 Individuals at ultra-high risk (UHR) for psychosis tend to show cognitive performance intermediate to FEP and healthy controls, suggesting there may be deterioration in cognitive ability over the transition to psychotic disorder. The only way to truly determine deterioration in cognition is through longitudinal within-subject studies. A relatively large number of studies of FEP suggest no deterioration is evident in the first few years postpsychosis onset.2 Longitudinal UHR studies show similar results, but these often have small sample sizes.3 ,4
