AP PSYCHOLOGY

Detailed explanation-1: -Many patients with schizophrenia show clinical signs of frontal lobe dysfunction, including blunted affect, difficulty with problem solving, and impoverished thinking.

Detailed explanation-2: -Schizophrenia is associated with changes in the structure and functioning of a number of key brain systems, including prefrontal and medial temporal lobe regions involved in working memory and declarative memory, respectively.

Detailed explanation-3: -Thirty-eight schizophrenics and 49 normal controls underwent magnetic resonance imaging. Midline sagittal cuts indicated that the schizophrenics had significantly smaller frontal lobes, as well as smaller cerebrums and craniums.

Detailed explanation-4: -Both structural and physiological frontal abnormalities have been reported in schizophrenic patients, but the findings have often been contradictory. Magnetic resonance imaging (MRI) studies have found reduced volume in the frontal lobe.
