NCT06662526 · Phase 4 · NOT YET RECRUITING

Lithium for Prevention of Cognitive Declining in Mood Illnesses

This trial is testing whether a very low daily dose of lithium (50 mg, far below standard psychiatric doses) can slow or prevent the development of mild cognitive impairment in people who already have a mood disorder like depression or bipolar disorder. It is a Phase 4 trial, meaning lithium is already approved for other uses, but researchers are studying this specific low-dose, neuroprotective application in a new population.
