Alzheimer's potential new treatment through Lithium, as per a Harvard research, indicates a connection between the metal and the disease
Lithium: A Promising New Approach to Alzheimer's Treatment
Recent research indicates that lithium, a naturally occurring element in the brain, may play a crucial role in preventing memory decline and Alzheimer's disease. The studies suggest that lithium deficiency could contribute to the early pathological changes associated with Alzheimer's, such as the accumulation of amyloid plaques and tau tangles.
In experiments on mouse models, restoring lithium levels (particularly through novel lithium compounds or low-dose lithium orotate) has shown promising results in reversing memory loss and brain pathology linked to Alzheimer's. Lithium deficiency appears to occur due to the element being sequestered by amyloid plaques, impairing its normal brain uptake and protective effects.
These findings open up avenues to explore low-dose lithium formulations as a potential preventive and therapeutic strategy for Alzheimer's disease. While current treatments, such as anti-amyloid drugs, only modestly slow decline without restoring memory or stopping progression, lithium's potential to reverse memory loss offers a new promising approach.
Researchers from Harvard Medical School have discovered that a lack of lithium in the brain speeds up memory decline, contributing to Alzheimer's disease. In mouse models of Alzheimer's, a lack of lithium dramatically accelerated the formation of beta-amyloid plaques and structures similar to neurofibrillary tangles. Additionally, a lack of lithium activated microglia, a type of inflammatory brain cell, reducing its ability to degrade amyloid.
Maintaining stable lithium levels in the early stages of life has been shown to prevent the onset of Alzheimer's in mice. Lack of lithium has been linked to the loss of synapses, axons, and myelin, which protect neurons, and accelerated cognitive decline and memory loss, all of which are characteristics of Alzheimer's disease.
However, it is important to note that the safety and effectiveness of lithium treatment for neurodegeneration in humans has not yet been proven. The researchers emphasise the need for caution and stress the importance of confirming the effects of lithium on humans, determining safe doses, and assessing potential side effects.
In summary, lithium appears to be a promising new approach to Alzheimer's treatment, particularly through formulations that improve brain lithium availability without toxicity. Detection of lithium through routine blood analysis could potentially identify individuals at risk of developing Alzheimer's. While more research is needed, the potential benefits of lithium in treating Alzheimer's disease are significant and warrant further clinical testing in humans.
