What is Alzheimer’s disease?

The severity of the disorder is not the same for everyone. It differs from person to person. “But the disorder follows an arbitrary pattern”, says Dr Barry Reisberg of New York University.

Hence this blog breaks down the seven stages of Alzheimer’s disease based on the theory of Dr Resiberg’s system
