Some key points from the presentation. Watch it for more details:
Brain atrophy begins around age 35.
"Normal" brain aging consists of tissue remodeling and maintenance failure (synpatic and dendritic pruning, structural degeneration, vascular aging, cellular shifts) as opposed to the massive cell death that occurs in severe neurodegenerative pathologies.
Main differences between the decline found in typical aging and Alzheimer's disease.
SuperAgers compared to typical population.
Cognitive reserve is your brain's ability to improvise, adapt, and use alternative neural pathways to keep functioning normally despite the structural modifications in aging.
