New research reveals that lithium helps protect against neurodegeneration and Alzheimer's disease by preventing toxic amyloid plaques from disrupting brain function.

A Harvard study suggests lithium loss may be linked to Alzheimer's, offering hope for early detection and new treatments, though experts urge caution.

A new study found that lithium is essential for normal brain cell function, with researchers observing increased inflammation and accelerated aging in Alzheimer’s-prone mice fed lithium-deficient diets.
