The Claim

Daily supplementation with cocoa extract for three years has no significant effect on the incidence of mild cognitive impairment or dementia, nor on the rate of cognitive decline preceding diagnosis, in adults aged 65 and older.

Cause and effect
1 study reviewed
In plain English

Taking cocoa extract every day for three years does not change the likelihood of developing mild cognitive impairment or dementia, and does not slow the rate of cognitive decline in people aged 65 and older.

See the scientific wording

Daily supplementation with cocoa extract for three years has no significant effect on the incidence of mild cognitive impairment or dementia, nor on the rate of cognitive decline preceding diagnosis, in adults aged 65 and older.

Why this might work

Cocoa extract does not change the biological processes that lead to memory loss or brain function decline in older adults, because it does not alter brain blood flow, reduce brain inflammation, or protect nerve cells from damage over time.
