Lithium deficiency may be the hidden spark behind Alzheimer’s

• Study shows for the first time that lithium plays an essential role in normal brain function and can confer resistance to brain aging and Alzheimer’s disease.
• Scientists discovered that lithium is depleted in the brain by binding to toxic amyloid plaques — revealing a new way Alzheimer’s may begin.
• A new class of lithium-based compounds avoids plaque binding and reverses Alzheimer’s and brain aging in mice, without toxicity.
