The effect of cognitive functioning on treatment attendance and adherence in comorbid bipolar disorder and cocaine dependence.


Journal Article

Although bipolar disorder and substance dependence are both associated with treatment non-adherence and cognitive impairment, no studies have investigated relationships between treatment adherence and cognitive functioning in this population. As part of a clinical trial, baseline performance on two neuropsychological tests in 120 outpatients with bipolar disorder and cocaine dependence was used to examine whether cognitive functioning was associated with appointment attendance, medication adherence, and return of medication bottles. This study found that higher baseline cognitive functioning measured by the Stroop Color-Word condition predicted better treatment adherence. However, this study also reports measurement sensitivity of cognition as it relates to treatment adherence when applied to this dual diagnosis population. Poorer performance in simple visual attention tasks as assessed by the Stroop Word condition was inversely associated with some measures of adherence. Future studies are warranted that include a comprehensive neuropsychological battery and advanced medication adherence measures to confirm these findings.
