THE DIMENSIONS CONSIDERED ARE THE NATURE OF CURRENT AND PAST OFFENSES AND THE DEGREES OF VIOLENCE AND IMPULSIVENESS IN THE CURRENT OFFENSE. NO SIGNIFICANT DIFFERENCES BETWEEN EPILEPTICS AND NONEPILEPTICS ARE FOUND. LIKE OTHER PRISONERS, THE VAST MAJORITY OF EPILEPTIC INMATES WERE NONVIOLENT THIEVES. WITHIN THE EPILEPTIC GROUP, THOSE DIAGNOSED AS SUFFERING FROM TEMPORAL LOBE EPILEPSY HAD HIGHER OVERALL RATES OF PREVIOUS CONVICTIONS, BUT THOSE WITH IDIOPATHIC (OF UNKNOWN ORIGIN) EPILEPSY HAD HIGHER RATES OF CONVICTIONS FOR VIOLENT CRIMES. IMPLICATIONS OF THE FACT THAT HOSPITALIZED EPILEPTIC OFFENDERS WERE NOT INCLUDED IN THE SAMPLE ARE POINTED OUT. THE SCALES DEVISED TO MEASURE THE DEGREES OF VIOLENCE AND IMPULSIVENESS INVOLVED IN OFFENSES ARE DESCRIBED. SUPPORTING DATA AND A LIST OF REFERENCES ARE PROVIDED. (LKM)
