22q11.2 deletion syndrome (22q11.2DS) is a neurogenetic condition associated with increased risk for schizophrenia. No study do date has explored how positive and negative symptoms of psychosis are distributed among individual patients with 22q11.2DS and if distinct patterns of symptoms can be identified. Negative symptoms being more frequent than positive symptoms in 22q11.2DS, we expected that a high number of patients would display predominant negative symptoms (PNS), whereas predominant positive symptoms would be less frequently reported. The present study aims at investigating the cognitive deficits and functional outcome associated with distinct patterns of psychotic symptoms in 22q11.2DS. 63 adolescents and young adults with 22q11.2DS participated in this study. Each participant underwent a clinical and a cognitive evaluation. A cluster analysis was used to identify groups of individuals with distinct patterns of symptoms. Individuals from the different clusters were then compared on a series of cognitive measures and on functional outcome. Three clusters of individuals were identified: low levels of symptoms, PNS, and high levels of symptoms. Individuals with PNS had significantly lower visual memory scores and decreased processing speed compared to participants with low levels of symptoms. They were also rated as having lower functional and occupational outcome. The present results indicate that one third of adolescents and young adults with 22q11.2DS display PNS. This pattern of symptoms was associated with specific cognitive deficits and decreased functional outcome. Future studies are needed to examine the developmental trajectories of these individuals and assess their risk of conversion to full-blown psychosis.
