Summary
A study by Harvard Medical School found that lithium in the brain might influence the development of Alzheimer's disease. Lithium levels were lower in brains with Alzheimer's compared to healthy ones, suggesting a potential link. Researchers noted that more trials are needed before lithium can be recommended for treatment or prevention.
Key Facts
- The study was conducted by Harvard Medical School and led by Dr. Bruce Yankner.
- It found natural lithium in the brain might prevent and treat cognitive decline.
- Lower lithium levels in the brain were linked to more amyloid plaques and tau tangles, which are linked to Alzheimer's.
- Researchers were able to reverse Alzheimer's effects in mice using lithium orotate.
- The study used advanced tools to detect trace metals in brain tissue, which wasn't possible before.
- Experts caution that human trials are needed before lithium use is advised for Alzheimer's.
- The study was published in the journal Nature.
- Lithium is a naturally occurring element used in various applications, from batteries to mood stabilization.
