Status: Strong Research Support
Cognitive functions such as executive function, learning & memory, processing speed, and sustained attention are frequently impaired and play an important role in the functional impairments seen in schizophrenia. Cognitive remediation (CR) or cognitive rehabilitation interventions are designed to improve cognitive function through repeated practice of cognitive tasks and / or strategy training. CR interventions are typically time-limited. They can be conducted individually or in groups. Some involve extensive use of computers while others focus primarily on paper-and-pencil tasks. Most CR interventions take into account the motivational and emotional deficits that are often present in schizophrenia as well. The goal of CR is to improve cognitive function. Research has shown small to medium effects of CR on neuropsychological measures of cognition, but whether these improvements are sustained or whether they translate into improved functioning remains unclear.
