About this trial

The purpose of this placebo-controlled trial is to compare the effects of 24-weeks supplementation with LPC-DHA and TAG-DHA on cerebrospinal fluid and blood DHA levels, as well as biomarkers of central neurodegenerative and neurotrophic activity, in elderly adults experiencing early signs of cognitive/memory decline including those with mild cognitive impairment (MCI). Extant evidence supports our overarching hypothesis that LPC-DHA supplementation will be more effective than TAG-DHA for increasing central (CSF) DHA levels and improving biomarker profiles in elderly adults. To assess this hypothesis, the following aims are proposed:

SPECIFIC AIM 1: To compare the effects of LPC-DHA and TAG-DHA supplementation on peripheral and CSF DHA levels in elderly adults experiencing early signs of cognitive/memory decline.

SPECIFIC AIM 2: To compare the effects of LPC-DHA and TAG-DHA supplementation on neurotrophic and neurodegenerative biomarkers.

Secondary Aim: To investigate whether changes in CSF DHA levels correlate with changes in objective measures of executive functioning and episodic memory performance.

Eligibility criteria

Qualifiers

men and women 55 to 82 years old;

presence of subjective cognitive decline or mild cognitive decline using the SCD questionnaire, DEX, EMQ, MoCA; and mCDR;

No contraindication to a lumbar puncture (LP) unless opting to not have the LP (e.g., thrombocytopenia, coagulopathy, concomitant use of anticoagulant medications, etc.);

fluency in English;
