Abstract
It has been suggested that impulsivity and aggression are associated w ith neuropsychiatric impairment. Neurological soft signs may be a usef ul marker of nonspecific brain damage, and may therefore be increased in impulsive and aggressive patients compared with normal control subj ects. A structured examination was used to evaluate neurological soft signs in 28 patients with personality disorders characterized by impul sivity and 28 healthy control subjects. All of the patients met DSM-II I-R criteria for borderline personality disorder, and 10 also met crit eria for antisocial personality disorder. All patients were questioned about past history of physical aggression, and a subset of 18 patient s underwent neuropsychological testing with a select battery. Left-sid ed neurological soft signs were significantly increased in patients co mpared with normal control subjects. Patients with a history of aggres sion, however, had significantly more right-sided neurological soft si gns than those without a history of aggression. Increased neurological soft signs were associated with impairment on the Wisconsin Card Sort , a test of frontal lobe executive function. Specific neuropsychiatric abnormalities, such as lateralized neurological soft signs and associ ated impairment on select neuropsychological tests, may be present in patients with personality disorders characterized by impulsivity.
