Minor physical anomalies occur with increased frequency in retarded,
hyperactive, and autistic children, which suggests the effects of genetic
influences or a toxic early uterine environment. The author's findings
concur with previously published reports concerning hyperactive and
autistic children. Extending these studies to adult patients, they found an
increased incidence of minor physical anomalies in schizophrenic adults.
Alcoholic adults did not have a greater number of anomalies than normal
adults, but the distribution among alcoholics appeared to be bimodal,
suggesting heterogeneity within this group.
