ALA-enriched nutrition to prevent cognitive decline in older adults with APOE4

Official title: Alpha Linolenic Acid-enriched Nutrition for Prevention of Cognitive Decline in APOE4 Older Adults With Mild Cognitive Impairment: Targeting Cerebrovascular and Blood-brain Barrier Health

Run by Rutgers, The State University of New Jersey · NCT07392723 · Data updated 2026-11-12

This study will test whether taking daily alpha-linolenic acid (ALA) supplements can slow cognitive decline and improve brain blood-vessel and barrier health in older adults with mild cognitive impairment who carry the APOE4 gene.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 60 or older with amnestic mild cognitive impairment who carry at least one APOE4 allele, can give informed consent, are fluent in English or Spanish, and have a study partner available.

Probably not a fit

Patients with dementia or other major neurological diseases, recent stroke, active cancer treatment, allergy to flaxseed or corn oil, or who are already taking flaxseed/fish oil supplements may not benefit or be eligible.

What this trial studies

This is a randomized, double-blind, placebo-controlled Phase 2 pilot trial enrolling 60 older adults (age ≥60) with amnestic mild cognitive impairment who carry at least one APOE4 allele. Participants will be randomized to receive either 2.6 g/day of ALA (from flaxseed oil) or a placebo (corn oil) for six months, with both participants and staff blinded to assignment. Primary outcomes include change in global cognition and MRI measures of blood-brain barrier integrity and brain vascular health, and secondary outcomes include episodic memory and executive function. The trial aims to increase brain DHA synthesis from ALA and measure downstream biochemical and imaging changes associated with vascular and cognitive function.

Why it matters

Potential benefit: If successful, ALA supplementation could offer a safe, low-cost way to raise brain DHA levels and slow cognitive decline in older APOE4 carriers.

How similar studies have gone: Prior DHA supplementation trials showed limited cognitive benefits in APOE4 carriers, so using ALA to boost endogenous DHA synthesis is a novel and as-yet unproven approach in this population.
