There’s exciting news in the world of brain research. In a study published recently in the Journal of Alzheimer’s Disease, researchers at Johns Hopkins Medicine have identified a correlation between the loss of a well-known “feel-good” neurotransmitter and memory loss; and that memory loss could later progress to Alzheimer’s disease. Find out which neurotransmitter is involved, and why investigators are hopeful that their discovery can be leveraged to improve cognitive deficits and slow and treat the progression of Alzheimer’s disease.
