Despite decades of research, Alzheimer's disease remains a debilitating and eventually fatal dementia with no effective treatment options. More than 95 percent of Alzheimer's disease cases have no known origin.

These neurons have a loss of functional activity, impaired metabolism, and increased brain inflammation.
