Neurocognitive deficits and prefrontal cortical atrophy in patients with schizophrenia

Prefrontal gray matter abnormalities in schizophrenia patients may be associated with some symptoms including difficulties with set-shifting and decreased mental flexibility. Further studies evaluating prefrontal connectivity may clarify if such impairment results from abnormalities of the frontal area alone, or are a result of altered networks involving the frontal and extra-frontal areas.
