Alzheimer's & Dementia

Alzheimer’s disease is an irreversible, progressive brain disorder that slowly destroys memory and thinking skills. Alzheimer’s is the most common cause of dementia among older adults. Dementia is the loss of cognitive functioning—thinking, remembering, and reasoning—and behavioral abilities to such an extent that it interferes with a person’s daily life and activities.

New study identifies dopamine's role in reversing Alzheimer's

Imagine if patients with Alzheimer's could have their memories restored. Such a future may seem like a pipe dream, but a new study by researchers at Tohoku University, in collaboration with the University of California, Irvine, has identified dopamine dysfunction as a previously unrecognized mechanism underlying memory impairment, unlocking a potential therapeutic means of reversing cognitive decline.
