title: Thyroid and vitamin-mineral supplement fail to improve IQ of mentally retarded adults.
abstract: Institutionalized profoundly mentally retarded adults (N = 37) were studied to determine whether thyroid medication is an essential component of a recently introduced nutritional supplementation treatment. Biochemical assessments confirmed that compliance with the treatments was adequate; however, no significant IQ improvements were observed.
