Could lithium be the missing piece of the Alzheimer's disease puzzle? In recent years, the field has made great strides, with the development of the first treatments capable of reversing dementia and new blood screening tests. However, Alzheimer's disease still has many gray areas. Some key mechanisms are now known, such as the role of two proteins (beta-amyloid and tau) that accumulate in the brain and prevent neurons from functioning properly. Certain genes, such as APOE, are among the unfavorable factors, as is an unhealthy lifestyle. But what exactly triggers this disease? What is the common thread between this range of symptoms? After more than a decade of work, lithium could be a solid lead, according to a study published in Nature.
