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

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
