At AAIC, Dr. Marwan Sabbagh explains why Alzheimer’s blood tests are not yet recommended for people without symptoms and highlights promising directions in treatment research. Alzheimer’s blood tests are advancing rapidly, but should people without memory symptoms use them to determine if they have signs of the disease in their brains?

Chronic traumatic encephalopathy (CTE) is a degenerative brain disease tied to repeated head trauma. Here's what researchers know about its symptoms, how it differs from Alzheimer's, and what people living with it say helps. A growing body of research suggests that, for some athletes and others exposed to repeated blows to the head, those impacts may accumulate over a lifetime and, decades later, contribute to a degenerative brain disease known as chronic traumatic encephalopathy, or CTE.

Memory loss is not always the first sign of early-onset Alzheimer’s. Dr. Gil Rabinovici explains the lesser-known symptoms and advances in diagnosis.
