A decade-long study by Harvard scientists suggests that lithium deficiency, triggered by amyloid plaques in the brain, may be a key factor in the early stages of Alzheimer’s disease. By testing innovative lithium compounds that evade plaque capture, researchers were able to reverse memory loss in mice at far lower doses than those used for psychiatric treatments.

New research suggests that physical exercise can make your brain act up to four years younger, offering promising strategies to reduce the risk of dementia and Alzheimer’s disease. Even minimal daily activity may provide significant cognitive benefits, highlighting the profound impact of exercise on brain health.
