Dopamine deficiency found to drive memory impairment in Alzheimer's disease

Dopamine Depletion: The Hidden Driver of Alzheimer’s Memory Loss

Summary: For decades, Alzheimer’s research has focused almost exclusively on toxic proteins like amyloid-beta and tau. However, a new study has identified a new culprit: dopamine dysfunction in the entorhinal cortex. Researchers discovered that dopamine levels in this critical “memory gateway”…

Dopamine deficiency found to drive memory impairment in Alzheimer's disease

Why do memories fade in Alzheimer's disease—and can they be restored? University of California, Irvine researchers have uncovered a key mechanism underlying memory loss, showing for the first time that dopamine dysfunction in the entorhinal cortex, a critical memory-related brain region, contributes directly to impaired memory formation. The study, published in Nature Neuroscience, identifies a previously unrecognized role for dopamine in Alzhei…
