Background@#Alcohol consumption has been considered as a modifiable risk factor for dementia development and alcohol-related brain damage may further impair cognitive abilities in dementia patients. This study aimed to find out the differences in cognitive function according to current alcohol drinking in patients with self-perceived memory decline, including subjective cognitive decline (SCD), mild cognitive impairment (MCI) and early Alzheimer-type dementia (ATD). @*Methods@#From May 2018 to December 2019, retrospective chart review was performed in patients who visited CHA Bundang Medical Center for cognitive decline. A two-way analysis of variance with interaction test were used to analyze the impact of alcohol consumption on cognitive function between groups. @*Results@#A total of 147 patients was classified into three groups of SCD (n=30), MCI (n=53), and ATD (n=64), and each group was divided into two subgroups of alcohol users and alcohol non-users, according to the current status of alcohol consumption. Between SCD, MCI and ATD groups, scores of clock drawing test and Go/No-go test were significantly lower in current alcohol users of ATD groups compared to the SCD and MCI groups (p<0.05). @*Conclusions@#These results suggest that current alcohol consumption has detrimental effects especially on the frontal/executive function in early ATD patients. Considering the association between frontal/executive function and ADL, our finding suggests that cessation of alcohol intake may be a therapeutic strategy to prevent ADL deterioration in patients with ATD.
