A brain injury caused during the stroke may be the cause of the behavioral change, reveals a new study. Researchers in Korea found a distinct correlation between the location of brain lesions caused by a stroke and the display of anger and aggression. In fact, of the 145 patients examined, 32 percent were unable to control anger and aggression as a result of a stroke. Those emotions were most obvious when the lesions were present in the frontal, lenticulocapsular, and pontine base areas. The study used the Speilberger Trait Anger Scale to assess the patients' pre- and post-stoke status. Input from relatives living with patients was included. The 10-item scale includes statements about feelings and emotions. Patients rated each statement on a one to four scale with four representing "almost always" to describe their feelings. Some statements include, "I am quick-tempered," "I fly off the handle," and "When I get frustrated, I feel like hitting someone." Lead study author Jong S. Kim, M.D., says, "Anger and aggression seems to be a behavioral symptom caused by disinhibition of impulse control that is secondary to brain lesions, although it could be triggered by other peoples' behavior or by physical defects."
