Effect and Safety of Non-invasive Electrical Stimulation in Alzheimer's Disease
Effect and Safety of Non-invasive Electrical Stimulation in Improving Cognitive and Depressive Symptoms in Alzheimer's Disease
Source: ClinicalTrials.gov · Last updated 27 Jul 2026
Brief summary (registry, in English)
Alzheimer's disease (AD) is the most common neurodegenerative disorder, characterized primarily by cognitive impairment as its main clinical symptom, often accompanied by emotional disturbances such as depression and anxiety, imposing a significant disease burden. Temporal Interference Stimulation (TIS) is an emerging non-invasive electrical stimulation technique that precisely targets deep structures within the hippocampus through interference of multiple electric fields. This study will administer a two-week TIS treatment to patients with AD co-occurring depression, targeting the hippocampus, and compare changes in patients' cognitive function, scores on depression and anxiety scales, and functional magnetic resonance imaging (fMRI) data before and after treatment. An emotional word recall task will be administered during fMRI scans. The aim of this study is to investigate the efficacy, safety, and neural mechanisms of TIS-mediated modulation of hippocampal circuits in improving cognitive and emotional functioning in patients with AD and comorbid depression.
