Research Links Psychotic Disorders With Increased Age-Related Cognitive Impairment

People with psychotic disorders had declines in their cognitive performance that were greater than would have been expected from normal aging. People with psychotic disorder performed worse on all cognitive tests compared to a control group of people without psychotic disorders. Cognitive decline was associated with worse functioning and negative symptoms of psychosis. The tests assessed verbal knowledge, verbal declarative memory, visual declarative memory, attention and processing speed, executive function, and verbal fluency.

These findings were reported in “Long-Term Changes In Cognitive Functioning In Individuals With Psychotic Disorders; Findings From The Suffolk County Mental Health Project” by Anne-Kathrin . . .
