Relation between cognitive testing performance and pattern of substance use in males at treatment entry.
This study examined the frequency and pattern of cognitive impairment in individuals entering substance use disorder treatment and additionally examined the relation between pattern of cognitive impairment and type of substance(s) used: alcohol (n = 116), cocaine (n = 49), alcohol/cocaine (n = 76), and alcohol/multiple substance (n = 54). The Cognistat, a screening measure of cognitive functioning, and the Addiction Severity Index were given to male veterans at the time of entering 3- to 4-week residential/day drug treatment. The most prominent areas of impairment were memory (37% of the total sample) and similarities or abstract concept formation (21% of the total sample). Moderate or greater severity of impairment was noted on at least one Cognistat scale in 35% of the participants. Results indicated no significant differences in the patterns of cognitive domain impairment between groups based on type(s) of substances used at the time of entering treatment. Multiple substance use was significantly related to greater levels of psychiatric problems as identified by the Alcohol Severity Index. Given the rate of impairment in memory and verbal abstract reasoning noted, it is suggested that cognitive screening be a standard consideration in residential substance use disorder treatment to assist in treatment selection and delivery that is optimized to provide maximal benefit to patients.
