Cognitive functioning under moderate and low dosage methadone maintenance.
The Wechsler Adult Intelligence Scale (WAIS) was administered to two groups of patients in the Santa Clara County Methadone Maintenance Program who were receiving low and moderate daily stabilized dosages of methadone hydrochloride. In the two separate statistical analyses performed, there were no significant differences found between subtest scores or verbal, performance, and full-scale scores of the groups measured. These results, combined with observations regarding the similarities of WAIS profiles of the two groups, indicate that cognitive functioning as measured by the WAIS was not differentially affected by the two dosages.
