title: Evidence for psychopathology in patients with rhythmic midtemporal discharges.
abstract: In order to obtain further evidence of possible psychopathology, the Minnesota Multiphasic Personality Inventory (MMPI) was administered to 25 patients (pts) who had the controversial EEG pattern of rhythmic midtemporal discharges--(RMTD) psychomotor variant. The pts were divided into a retrospective and prospective group, the former consisting of only a minority (36%) of pts who had previously agreed to cooperate and the latter consisting of every pt (100%) showing the pattern in a 3-year period. The scores of all RMTD pts were abnormal (approximately 2 SD above the normal mean) for hypochondriasis, schizophrenia, depression, and hysteria and were classified as Abnormal on Rule 1 on the Goldberg sequential diagnostic system. Patients with intermediate or many bursts of this pattern were also classified as Abnormal, scored higher on every clinical scale, significantly so on five of the clinical scales and were significantly different with regard to the number of clinical scale scores at or over the T value of 70 as well as 80. The MMPI profile of RMTD pts is similar to those with definite temporal lobe epilepsy but different from pts with general medical disorders.
