Abstract

Background

Cognitive processes are impaired in Schizophrenia (SKZ). The nature of such impairment escapes definition.

Aim

Identification of a genetic profile at risk of cognitive impairment.

Object

Identifying a molecular pathways enriched for mutations associated with cognitive impairment.

Methods

Seven hundred and sixty-five individuals from the CATIE, M = 556, mean age = 40.93 ± 11.03 were included. Verbal memory was outcome. R and Plink served for the analyses. Inflation factor was controlled by lambda values. Input for the pathway analysis were SNPs associated with outcome (P < 0.05) genomewide.

Results

Gender (male, P = 2.34e–05;t = –4.26) and years of education (P = 1.57e–03;t = 6.502) were associated with verbal memory. Inflammation and oxidation were associated with outcome (Table 1, adj_P < 0.01).

Conclusions

Being male and poorly educated were associated with poorer verbal memory. Inflammation and the arachidonic acid pathway were enriched in mutations associated with poorer verbal memory. This finding is in line with previous reports [1,2,3].
