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.

Parkinson's Drug Restores Memories in Alzheimer's

Severe dopamine dysfunction in the entorhinal cortex is a primary, hidden mechanism behind Alzheimer's-related memory impairment. Researchers found that dopamine levels in this vital memory gateway drop to less than 20% of normal, causing localized neurons to stop encoding memories altogether.
