Researchers have uncovered a surprising new mechanism behind memory loss in Alzheimer’s disease, identifying dopamine deficiency as a major contributor to cognitive decline. The discovery could open the door to new treatment approaches aimed at restoring memory in patients suffering from the disease.
The study was led by scientists at Tohoku University in collaboration with researchers from the University of California, Irvine. Their findings were published in the journal Nature Neuroscience on April 23, 2026.
