A STUDY OF COGNITIVE FUNCTION IN NIGERIAN PATIENTS WITH SCHIZOPHRENIA, THEIR FIRST-DEGREE RELATIVES AND HEALTHY CONTROLS.

This study provided needed Nigerian data on cognitive function using standard brief instruments. The results affirm cognitive deficits as significant symptoms in patients with schizophrenia and also as possible endophenotypes of the disorder. Modifiable correlates of cognitive impairment were identified. More routine clinical assessment of cognitive function and research for possible treatments for cognitive impairments are necessary. Continued search for endophenotypes or other predictors of individuals at risk of schizophrenia should be encouraged.
