Perceptuomotor function of homeless males in alcohol rehabilitation.

In a sample of 76 alcohol rehabilitation program (ARP) residents, homeless men demonstrated significantly poorer perceptuomotor function than nonhomeless men. This difference persisted despite similarities in several factors associated with neurobehavioral test scores including demographic characteristics; frequency, quantity, and duration of alcohol and other substance use; psychosocial factors, including motivation and social support; health, including history of head trauma; and neurotoxic occupational exposure.
