Episode notes
Early Alzheimer's Pathophysiology
- Alzheimer's begins silently decades before symptoms, involving amyloid and tau proteins.
- Amyloid may protect neurons initially but harms synaptic communication if not cleared.
Alzheimer's Disease Complexity
- Alzheimer's disease is not mostly genetic, and many cases are not determined by known risk genes.
- Beta amyloid acts as a protective molecule linked to brain inflammation, not just a harmful agent.
Brain's Housekeeping System
- The glymphatic system clears amyloid and other debris from the brain during deep sleep.
- This brain 'housekeeping' is crucial for preventing amyloid buildup and cognitive decline.
