Thirty-one individuals awaiting trial or sentencing for murder or undergoing an appeal process requested a neurologic examination through legal counsel.We attempted in each instance to obtain EEG,MRI or CT,and neuropsychological testing.Neurologic examination revealed evidence of" frontal"dysfunction in 20(64.5%).There were symptoms or some other evidence of temporal lobe abnormality in nine(29%).We made a specific neurologic diagnosis in 20 individuals(64.5%),including borderline or full mental retardation(9)and cerebral palsy(2),among others.Neuropsychological testing revealed abnormalities in all subjects tested.There were EEG abnormalities in eight of the 20 subjects tested,consisting mainly of bilateral sharp waves with slowing.There were MRI or CT abnormalities in nine of the 19 subjects tested,consisting primarily of atrophy and white matter changes.Psychiatric diagnoses included paranoid schizophrenia(8), dissociative disorder(4),and depression(9).Virtually all subjects had paranoid ideas and misunderstood social situations.There was a documented history of profound,protracted physical abuse in 26(83.8%)and of sexual abuse in 10(32.3%).It is likely that prolonged,severe physical abuse, paranoia,and neurologic brain dysfunction interact to form the matrix of violent behavior. |
