Delay of gratification and executive performance in individuals with schizophrenia: putative role for eating behavior and body weight regulation.

Objective: Impairment in executive functions and disturbed weight regulation are common features in individuals with schizophrenia on antipsychotics. Still, the clinical management of weight gain, including educational programs, is insufficient. Therefore, we hypothesized that distinct executive impairment is associated with the inability to self-control food intake.
