Abstract

OBJECTIVE: Patients with mild cognitive impairment (MCI) are at high risk for dementia. Excessive alcohol consumption is known to adversely affect cognitive function. This study aimed to investigate the relationship between alcohol consumption and the risk for dementia in a cohort of MCI patients. METHODS: Participants (n=416) with (MCI) who met Petersen's criteria were recruited from a nationwide, prospective cohort study of dementia and were followed for a median of 17.52 months (range 5.4-63.48). Alcohol consumption was evaluated at baseline. RESULTS: One hundred twenty seven individuals (30.5%) developed incident dementia (115 Alzheimer disease) during follow-up. Patients with current alcohol consumption at baseline had a higher rate of progression to Alzheimer's dementia than those without current alcohol consumption (hazard ratio 1.61 ; 95% confidence interval 1.03 to 2.53). CONCLUSION: Alcohol consumption may increase the risk of progression to Alzheimer's dementia in patients with MCI.
