Light to moderate alcohol consumption is associated with S100beta and amyloid beta levels in healthy older adults.
Heavy alcohol consumption has been associated with several adverse neurocognitive outcomes in older adults, though little is known about lower consumption levels. No study has investigated the associations between S100beta and amyloid beta (Abeta) serum levels (biomarkers that provide evidence of neurological pathology) and light to moderate alcohol consumption in healthy older adults without neurological conditions. Thirty-five healthy older adults underwent neuropsychological testing and fasting blood draw with subsequent serum S100beta and Abeta 1-40 level quantification. Increased S100beta levels were associated with increased frequency of alcohol consumption and increased total monthly consumption of alcohol. Increased Abeta levels were associated with increased quantity of alcohol consumption. Further work investigating possible mechanisms is needed, particularly longitudinal studies and studies employing neuroimaging.
