Psychiatric Disturbance in Mentally Handicapped Patients

Abstract

SummaryOne hundred and two mentally handicapped and severely mentally handicapped patients with behaviour disorders and superadded mental illnesses which, in most cases, had not responded adequately to oral medication, entered a 12-week study of fluphenazine decanoate depot injections. Some of the patients had the additional complications of epilepsy, organic brain damage, and physical handicap. Highly significant overall improvements occurred, irrespective of such factors as the patient's age, sex, degree of mental handicap, or co-existence of epilepsy, or brain damage. Hyperpyrexia was not encountered. Extrapyramidal disturbance in 22 of the patients, were mostly well controlled by antiparkinson medication; eight of the 12 patients with pre-trial extrapyramidal abnormalities lost these during the study. Fluphenazine decanoate injections proved a reliable drug-delivery system, which may improve difficult behaviours and enable the mentally handicapped patient to be more receptive to behaviour-shaping exercises, aimed at improving long-term personality adjustment.
