First seen Mar 20, 2026 · Last updated May 23, 2026 · Updated 8 times
Summary
This study is testing whether adding sodium benzoate (a common food preservative) to a gentle brain stimulation technique called tDCS can improve memory and daily function in people with early-stage Alzheimer's or mild cognitive impairment. About 140 participants will receive two weeks of tDCS and then be assigned to one of three doses of sodium benzoate or a placebo for 24 weeks. The goal is to see if the combination works better than tDCS alone.
