In two previous reports* it was stated that in the course of investigation on the effect of N-methyl-α,α-methylphenylsuccinimide (PM 396) upon petit mal epilepsy, a favorable action of this drug was noted on the psychomotor element sometimes associated with petit mal attacks. Since to date psychomotor epilepsy is the most difficult of all forms of epilepsy to treat and there are no outstanding drugs in the therapeutic armamentarium for the treatment of this condition, this particular investigation was carried further.
