Lithium offers significant potential in the battle against Alzheimer's disease.
Recent research published in August 2025 has shed new light on the role of lithium, a naturally occurring element in the brain, in resisting Alzheimer's disease. The study, conducted by a team of Harvard researchers, suggests that lithium depletion in the brain may trigger the onset of Alzheimer's disease and that replenishing lithium levels could potentially reverse its effects.
The study, which was published in the prestigious journal Nature, found that low-dose lithium supplementation reversed both pathological brain changes and memory loss in mice, even in animals with advanced disease. This form of treatment restored normal brain function across various cell types, including neurons, microglia, and oligodendrocytes.
The discovery builds on epidemiological studies linking higher environmental lithium exposure with lower dementia rates. The current study's findings pave the way for clinical trials testing low-dose lithium supplementation as a preventive or therapeutic strategy for Alzheimer's.
One compound that shows particular promise is lithium orotate, which avoids the toxic effects typical of standard lithium treatments, demonstrating strong efficacy without harm.
The study's results have generated a lot of interest and excitement in the scientific community. Philippe Amouyel, a professor at Lille University Hospital and director-general of the Alzheimer's Foundation, has expressed interest in the study, admitting to jumping on it when he saw its publication.
Alzheimer's disease affects over 35 million people worldwide, and treatments for the disease are inadequate. The study's findings could potentially revolutionize the understanding and treatment of Alzheimer's disease, offering a promising avenue to prevent and potentially reverse the disease.
The cause of Alzheimer's disease remains shrouded in mystery, but this study highlights the role of lithium in the disease. As clinical trials in humans are the anticipated next step to translate these findings, we look forward to seeing if lithium could indeed be the breakthrough we've been waiting for in the fight against Alzheimer's.

- The study published in Nature by a team from Harvard Medical School suggests that lithium depletion in the brain might trigger Alzheimer's disease, and replenishing lithium levels could potentially reverse its effects, especially through low-dose lithium supplementation.
- The discovery, which also includes the promising compound lithium orotate, could revolutionize the understanding and treatment of Alzheimer's disease, offering a potential new approach to combat this neurological disorder.
- Researchers, including Philippe Amouyel from Lille University Hospital, have expressed interest in exploring the role of lithium in Alzheimer's disease further, with the anticipation of future clinical trials testing low-dose lithium supplementation as a preventive or therapeutic strategy.
