Sequential Accelerated ITBS / Remote tDCS for Treatment of Neuropsychiatric Symptoms in Alzheimer's Disease: A Pilot Study
Baylor College of Medicine
Summary
The goal of this pilot study is to test a combination of two non-invasive brain stimulation methods, called iTBS (intermittent theta burst stimulation) and tDCS (transcranial direct current stimulation), in people with Alzheimer's Disease (AD) and related dementias (ADRD). This study will also explore whether the combined treatment shows promise for reducing neuropsychiatric symptoms like mood swings, apathy, and agitation, and will evaluate the impact of the treatment on caregivers. The main questions the study aims to answer are: 1. Is the combined brain stimulation treatment practical and well-tolerated? 2. Do preliminary results suggest that this treatment could help manage neuropsychiatric symptoms and support a larger study? Participants will: * Attend nine in-person visits over three months. * Complete one week of in-clinic brain stimulation sessions (iTBS) followed by four weeks of daily at-home brain stimulation sessions (tDCS). * Take part in brain scans, questionnaires, and brain activity tests before and after the treatment. This pilot study is a first step to assess whether this combined treatment approach is practical and whether it has potential to improve symptoms, laying the groundwork for larger studies in the future.
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 sy…

Interventions
- DeviceBrain Stimulation
This intervention is distinct because it combines two non-invasive brain stimulation techniques, intermittent theta burst stimulation (iTBS) and transcranial direct current stimulation (tDCS), in a sequential manner. Unlike studies that evaluate these techniques individually, this study explores their combined and complementary effects, with iTBS priming the brain to enhance the subsequent impact of tDCS. The sequential design leverages different mechanisms of action: iTBS delivers magnetic pulses to targeted brain areas to modulate neural activity, while tDCS applies a low electrical current for sustained modulation. This approach specifically targets neuropsychiatric symptoms (e.g., mood swings, apathy, and agitation) in individuals with Alzheimer's Disease and related dementias (ADRD), a population often underserved by traditional interventions. The study also evaluates the feasibility of at-home tDCS administration, making it unique in combining clinical and caregiver-managed treat
