Abstract

Objective: Co-occurring alcohol misuse and depression (CAD) are highly prevalent and are both with associated cognitive impairments. Few studies have assessed how cognitive functioning changes over time in association with improvements in alcohol use and/or depression. This is the first study to assess cognitive function and symptoms of depression and alcohol use in a CAD sample at baseline and again at 12-months. We explored whether reduction in alcohol use or improvement in symptoms of depression were associated with changes in cognitive functioning.

Methods: Neuropsychological assessment was administered at baseline and after 12-months in a CAD sample of 71 people who had participated in a psychological intervention in the interim. Changes in alcohol use and depression over 12 months were interpreted as potential factors in improvement in neuropsychological function.

Results: Depressive symptoms and alcohol use improved over 12-months while overall neuropsychological test performance was stable. Improvement in verbal memory, working memory and executive function was predicted by improvement in depressive symptoms measured by the BDI-II, but not by change in alcohol use quantity or frequency of heavy drinking.

Conclusion: Among people with CAD, alleviation of the symptoms of depression may have greater influence on cognitive functioning in areas such as memory and executive function, than a reduction in alcohol use. Further treatment outcome research in CAD samples should include neurocognitive assessments in order to elucidate our understanding of cognitive impairments and potential improvements with intervention.
