Alzheimer’s disease hits women harder than men. Nearly two-thirds of Americans who have Alzheimer’s are women, according to the Alzheimer’s Association. Worldwide, 47 million people are living with Alzheimer’s and other dementias — including nearly 6 million in the United States — so the number of women affected is staggering.
The neurodegenerative disorder’s most common form, called late-onset Alzheimer’s disease, occurs after age 65.
“We know Alzheimer’s disease can start 10 to 20 years before diagnosis,” said Roberta Diaz Brinton, a leading expert in Alzheimer’s disease biology and therapeutic development and inaugural director of the Center for Innovation in Brain Science at the University of Arizona Health Sciences.
