Transcranial Magnetic Stimulation for Mild and Moderate Alzheimer's Disease

Recruiting

This study will test the effects of repetitive transcranial magnetic stimulation (rTMS), a noninvasive brain stimulation therapy, on cognitively healthy older adults and in people with amnestic mild cognitive impairment due to Alzheimer's disease. The intervention is designed to improve cognition, including memory, in older adults.

  • Fluent English speaker
  • Willing and able to consent to the study directions and undergo imaging and neuropsychological testing at the specified time points
  • Patients with very mild or mild cognitive impairment (CDR 0.5 or CDR 1)
  • Participants with amnestic mild cognitive impairment must be able to bring a study partner to all visits

  • History of head trauma involving a loss of consciousness or alteration in consciousness
  • Physician diagnosis of another major neurologic or psychiatric condition
  • Known presence of a structural brain lesion (e.g., tumor, cortical infarct)
  • Any condition that makes imaging by MRI unsafe, such as the presence of pacemakers, aneurysm clips, artificial heart valves, ear implants, metal fragments, or foreign objects in the eyes, skin, or body
  • Longstanding history (i.e., longer than 10 years) of alcohol or substance abuse
  • Any significant illness or unstable medical condition that could make it difficult to comply with the study directions
  • Unable or unwilling to return for follow-up, undergo neuropsychological testing, transcranial magnetic stimulation, and MRI imaging

This study will use repetitive TMS to stimulate nodes of the default mode network in the brain, which is thought to support memory and be affected by Alzheimer's disease. Following the stimulation intervention, participants will receive a functional connectivity MRI to determine any changes in the brain. Participants will also undergo neuropsychological and memory testing to determine improvements in cognition. All study participants will receive the TMS intervention.
