Read our Alzheimer Disease research guide →This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing transcranial direct current stimulation (tDCS), a non-invasive procedure that uses mild electrical currents to stimulate the brain. Researchers want to see if using a stronger electrical current (4.0 mA instead of the standard 2.0 mA) can help more people with Alzheimer's disease experience meaningful improvements in memory and thinking. Some participants will receive the stronger stimulation, some will receive the standard strength, and some will receive a placebo (sham) treatment.
Current medications for Alzheimer's disease have limited benefits, and doctors are looking for new ways to help patients think more clearly and maintain their memory. Previous studies of this brain stimulation treatment have shown mixed results, with some people improving greatly while others improve only slightly—researchers think using a stronger stimulation level might help more people benefit.

You likely don't qualify if…
You will receive brain stimulation sessions where small electrical currents are delivered through electrodes placed on your scalp—this is painless and non-invasive. You'll be randomly assigned to receive either stronger stimulation (4.0 mA), standard stimulation (2.0 mA), or a sham (placebo) treatment, and you won't know which one you're receiving. Throughout the study, you'll complete memory and thinking tests to help researchers measure whether the treatment is helping.
