DNA hunt for early Alzheimer's clues
NCT ID NCT03645993
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study collected blood and DNA samples from 26 people with early-onset Alzheimer's disease and their close family members. Researchers analyzed the samples to find genetic changes and biomarkers that could help doctors diagnose, treat, and monitor the disease in the future. The goal was to better understand how the disease develops, not to test a new treatment.

Inclusion Criteria: * Diagnosis of early-onset Alzheimer's disease based on the NIA-AA diagnostic criteria as determined by the clinician.
