What this research studies

From your perspective, researchers will measure many small molecules (metabolites) in donated postmortem brain tissue from about 1,200 people who had clinical and neuropathologic exams. They will combine those metabolite profiles with clinical histories and genetic data to find biochemical pathways tied to cognitive decline. The team will emphasize complex lipids, fatty acids, inflammation-related lipids, gut-microbiome–related neurochemicals, and glucose/bioenergetic metabolites. Results are meant to point to brain-specific metabolic changes that could become targets for prevention or new treatments.

Who could benefit from this research

Good fit: Ideal candidates are older adults (or their families) who agree to enroll in cohort studies or brain-donation programs, including people with Alzheimer's, other dementias, or normal cognitive aging who consent to postmortem tissue donation.

Not a fit: People seeking immediate treatments or those who do not participate in brain-donation or cohort programs are unlikely to receive direct, personal benefit from this research.

Why it matters

Potential benefit: If successful, this work could identify new biological targets in the brain that lead to better ways to prevent or treat Alzheimer's and related dementias.

How similar studies have performed: Early, smaller postmortem metabolomic studies have reported differences linked to Alzheimer's, but they were limited by sample size and replication, so this larger effort aims to confirm and extend those findings.
