Clinical Trial Finds High-Dose Omega-3 Reaches Brain but Fails to Improve Cognition in Older Adults at Risk for Dementia
By
Pauline Anderson
Summary
A new clinical trial found that high-dose omega-3 supplements (DHA) reached the brain in cognitively unimpaired older adults at high risk for dementia, but did not improve memory, cognitive function, hippocampal volume, or reduce brain cell loss related to Alzheimer's disease, regardless of APOE epsilon 4 status.

· 3 pulledWhile omega-3s play an important role in brain health, this study suggests that high-dose supplementation alone may not be sufficient to prevent cognitive decline in older adults at risk for Alzheimer's disease.
The detection of DHA in cerebrospinal fluid confirms that the supplement reached the brain, yet this did not translate into measurable cognitive benefits.
These findings highlight the complexity of Alzheimer's disease and the need for multifaceted approaches to prevention.
