What if Alzheimer’s can be detected long before memory loss becomes obvious? This video explores new evidence that a blood marker tied to synaptic damage may begin rising about eleven years before expected dementia symptoms in hereditary Alzheimer’s disease.
You’ll learn what beta-synuclein is, why synapses matter, how researchers used the DIAN family cohort to map changes before symptoms, and why this could matter for earlier diagnosis, trial design, and treatment timing.
Topics covered:
Beta-synuclein and synaptic injury
Hereditary vs. sporadic Alzheimer’s
How DIAN estimates years to symptom onset
Why early biomarkers matter for treatment
Limits and cautions before clinical use
