ABSTRACT
One group of mental changes in stroke has in common a weakening of the normal social constraints on behavior. The behaviors resulting from this cause distress to others rather than to the patient. There has not been enough experimental work on these changes to justify a rigid taxonomy, but a tentative and arbitrary classification is as follows: (1) negative emotions not classifiable as major mood disorders, (2) euphoria, (3) emotional incontinence, (4) disinhibited behaviors of dementia, and (5) incontinence of urine and feces.
