Study: Lithium Deficiency a Potential Early Alzheimer's Sign
Scientists are studying Alzheimer's disease and found that people with early memory problems may have less lithium in their brains.
Giving mice with memory problems lithium orotate helped them remember things better.
This is because lithium seems to protect the brain.
Researchers think that measuring lithium levels in people could help find those at risk for Alzheimer's.
More research is needed, but this could lead to new ways to treat or even prevent the disease.
Study suggests lithium decline is an early sign of Alzheimer's.
Lithium levels were lower in those with mild cognitive impairment.
Restoring lithium reversed brain changes and memory loss in mice.
Lithium orotate reversed Alzheimer's-related damage in mice.
Measuring lithium levels may identify people at risk of Alzheimer's.
