Psychological correlates of psychogenic seizures were studied. The MMP
I, Portland Digit Recognition Test (PDRT; a forced choice measure of m
otivation), disability status, Face-Hand Test, and Finger Agnosia were
compared in 53 patients with medically intractable seizure disorders
who underwent intensive EEG monitoring. Using conventional neurologic
criteria, 64% had diagnoses of epileptic seizures (ES) and 36% had psy
chogenic seizures (PS). PS patients were significantly higher in numbe
r of somatoform MMPI profiles and likelihood of applying for financial
benefits, and significantly lower on the PDRT. PS patients made more
Finger Agnosia errors. Differences on the Face-Hand Test were of borde
rline significance. The results support the existence of multiple psyc
hometric correlates of PS.
