Lithium Shows Promise in Reversing Alzheimer's Symptoms

A Harvard study suggests that low lithium levels in the brain may be a 'missing link' in Alzheimer's disease development, with findings indicating that lithium deficiency correlates with increased amyloid plaques and cognitive decline. The research highlights the potential of lithium compounds, like lithium orotate, to restore memory and reverse brain damage in mice, but emphasizes the need for further human clinical trials to confirm these results.
