Drinking coffee reduces your risk of dementia, says study

Published 6 June 2012

Research has suggested drinking coffee could protect people over 65 against the onset of Alzheimer’s disease.

The study, published in the Journal of Alzheimer's Disease, involved 124 people aged 65 to 88 over two to four years, and monitored their memory and thinking processes. It reported that those with mild cognitive impairment who had higher blood caffeine levels did not develop Alzheimer's disease within the timescale of the study. With coffee being the main or only source of caffeine for participants, the study claims to provide the first direct evidence that moderate coffee intake is associated with a reduced risk of dementia.

Alzheimer's Society comment:

'This small study adds some further weight to the emerging evidence suggesting caffeine could prevent or delay the onset of Alzheimer's disease. As one of the first studies to include people with mild cognitive impairment, the results are significant. Further clinical studies and research into the link between caffeine and dementia is now needed.'
