Lithium to Prevent or Delay Dementia

Start: September 1, 2017

What Is This Study About?

This phase 4 clinical trial will test lithium, a drug approved to treat mania, depression, and other mental disorders, as a possible treatment that may delay dementia onset or slow its progression in older adults with mild cognitive impairment (MCI). Participants will be randomly assigned to take either lithium (beginning at 150 mg per day) or a placebo for two years. Participants will receive a neurocognitive assessment, biomarker tests using blood and cerebrospinal fluid samples, and brain imaging, at the start and after each year of the study.
