Novel Brain Stimulation Treatment for Neuropsychiatric Symptoms in Alzheimer’s Disease

Description

This study is designed to explore a new way to manage behavioral and emotional symptoms in people with Alzheimer’s Disease (AD) and related dementias (ADRD). Many people with these conditions experience mood swings, apathy, or agitation, which can be difficult to treat with current medications due to limited effectiveness and side effects. This research is testing whether two types of brain stimulation, called iTBS (intermittent theta burst stimulation) and tDCS (transcranial direct current stimulation), can be combined to provide a non-invasive and potentially effective treatment for these symptoms.

Brain stimulation is already used in other areas of medicine and involves applying gentle magnetic or electrical stimulation to the brain. iTBS uses short bursts of magnetic pulses, while tDCS uses a low electrical current. Both methods are painless, safe, and do not require surgery. This study is the first to look at combining these two techniques for people with AD/ADRD, based on findings from other research that suggest the combination might have stronger effects than either method alone.

Since this is a pilot study, the focus is on understanding whether the treatment process is practical for both patients and caregivers. This includes evaluating how easy it is for participants to attend the clinic sessions, whether caregivers can successfully administer the at-home treatments, and whether the overall process is manageable for families. In addition to these practical questions, researchers will also collect preliminary data to see if the treatment helps improve behavioral symptoms and measure any changes in the brain using scans and brain activity tests.

Participants will spend one week receiving treatments in a clinic and four weeks using a portable device for at-home sessions. Researchers will closely monitor participants throughout the study to ensure safety and will follow up to see if any improvements last after the treatment ends.

The study is an important step in understanding whether this new approach has potential to help people with AD/ADRD and whether it should be studied further in larger trials. It also aims to identify how to make the treatment process as smooth and effective as possible for patients and caregivers.
