Poor insight in schizophrenia has been recently thought to be a reflection of prominent and enduring neurocognitive impairments. Reports supporting this theory have implicated prefrontal and parietal lobe functions, among other parameters. The results of other studies have negated the role of neuropsychological abnormalities in poor insight. The analogy between poor insight in schizophrenia and anosognosia in neurological illness as proposed by one set of workers has been elucidated in this review and it appears quite promising. However, the drawing of definite conclusions from all this work has been deferred by us, because of the need for more uniform and standardized methodologies for research on the subject. Nevertheless, attempts to improve the cognitive processes, which affect insight in schizophrenia, may be done to gain better treatment outcome in this disorder.
