The Aging Brain

Alzheimer's is the disease everyone fears and few understand accurately. Eleven installments move from the private moment you notice your own mind changing through the clinical landscape, the drugs that actually exist, the neuroscience of what caregiving does to the caregiver's brain, racial disparities in who gets diagnosed, and the philosophical questions medicine cannot answer. The series closes by asking what persists when memory does not.
