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 study is testing transcranial direct current stimulation (tDCS)—a non-invasive treatment that uses mild electrical current to stimulate the brain—to see if a stronger dose works better for people with Alzheimer's disease. Researchers want to know if using double the standard stimulation intensity (4mA instead of 2mA) helps more people improve their ability to name things. The study will compare this stronger dose against a standard dose and a sham (placebo) treatment.
Right now, there are very few treatments that actually help with Alzheimer's symptoms, especially problems with naming and word-finding. Researchers have seen that this brain stimulation treatment shows promise, but results vary widely from person to person—some people improve a lot, while others improve only slightly. This trial exists to find out whether using a stronger electrical current would help more people benefit from the treatment.

You will receive brain stimulation sessions using electrodes placed on your scalp—a painless procedure that takes about 20–30 minutes. You will be randomly assigned to receive either the stronger dose (4mA), the standard dose (2mA), or a sham treatment where no real stimulation occurs. Over the course of the trial, you'll visit the research center multiple times for treatment sessions and testing to see if your ability to name objects improves.
