The human brain is an incredible, complex web of connections. Cells called neurons send signals from region to region, and their communication allows us to do everything from forming thoughts to accessing memories.
But for nearly 6 million Americans, neurodegenerative diseases like dementia, chronic traumatic encephalopathy (CTE), and Alzheimer’s disease prevent neurons from functioning properly. The progressive memory loss that characterizes these diseases is well-known. Yet the mechanisms that cause them—and ways to treat them—are still poorly understood. That’s partly because neurodegenerative diseases have different causes. CTE can be triggered by repeated head trauma, while fronto-temporal dementia is caused by a genetic
