This broad introduction emphasizes that cognition in schizophrenia provides clues to pathophysiology, treatment, and outcome.
Are there generalized or specific cognitive impairments in schizophrenia?
The argument over generalized or specific impairments is clouded by the fact that there is not a clear neuropsychological signature of schizophrenia. That is, most schizophrenia patients demonstrate at least some cognitive impairment, but, like other aspects of the illness, the severity and breadth of these impairments vary across patients.
Why is there a lack of consensus on schizophrenia?
This lack of consensus may reflect the heterogeneity of schizophrenia, and may also be a result of the relatively poor localising ability of many standard neuropsychological instruments. A variety of candidate brain regions and associated cognitive functions have thus been implicated in the psychopathology that characterises schizophrenia.
What is the history of cognition in schizophrenia?
The history of cognition research in schizophrenia can be roughly carved up into 3 eras: the early clinical observations that occurred in the beginning of the 1900s, the assessment-based approaches that emerged after World War II, and the more recent era (roughly the last 20 years) in which cognition research merged into other disciplines.
