Neuropsychiatric aspects of stroke.
Neuropsychiatric disorders following stroke are common, and pathologic involvement of specific regions or functional systems results in behavioral syndromes similar to idiopathic psychiatric syndromes. Depression occurs in up to half of all stroke patients and is most frequently associated with left anterior cortical and subcortical infarctions. Mood changes interfere with cognitive, functional and social recovery. Treatment with heterocyclic antidepressants, stimulants, and electroconvulsive therapy is efficacious in most patients. Mania, delusions, hallucinations, personality alterations, obsessive-compulsive disorder, and changes in sexual behavior are less common but have also been described in post-stroke patients. Each behavioral syndrome is associated with a specific pattern of brain involvement. Investigation of these phenomena contributes to understanding the cerebral basis of psychiatric disorders.
