Six-Year Follow-Up Study of Cognitive and Functional Status Across the Lifespan in Schizophrenia: A Comparison With Alzheimer’s Disease and Normal Aging

Abstract

Institutionalized schizophrenic patients demonstrated an age-related pattern of cognitive change different from that observed for Alzheimer's disease patients and healthy individuals. The cognitive and functional status of these schizophrenic patients was fairly stable until late life, suggesting that cognitive change may not be occurring in younger patients over an interval as long as 6 years.
