About this trial

In this research study we want to learn more about the effects of non-invasive brain stimulation on memory and brain-network function in cognitively unimpaired older adults and in patients with amnestic mild cognitive impairment (aMCI).

This study will use a form of non-invasive brain stimulation called repetitive Transcranial Magnetic Stimulation (rTMS). rTMS will slightly alter activity in an area of your brain that controls memory. Changes resulting from this stimulation will be measured with behavioral tests of memory and general cognition, as well as by taking images of your brain with Magnetic Resonance Imaging (MRI).

Participants will come in for one baseline visit followed by 10 days of daily rTMS study visits (Monday through Friday) and an evaluation visit. Then, there will be a 2-week break. After this break, they will return for another baseline visit, an additional 10 days of rTMS, and a final evaluation visit.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Between the ages of 40-99

Native English speakers

Willing and able to consent to the protocol and undergo imaging and neuropsychological testing at the specified time points

Patients with PPA will be asked to bring a study partner to all visits

Disqualifiers

History of head trauma involving loss of consciousness or alteration in consciousness

Another major neurologic or psychiatric condition

Known presence of a structural brain lesion (e.g. tumor, cortical infarct)

Any contraindication to MRI, such as presence of pacemakers, aneurysm clips, artificial heart valves, ear implants, metal fragments, or foreign objects in the eyes, skin, or body

Trial design

Design model

Single group

Treatments tested in this trial

  • Active rTMS

    Device

    All study participants will receive one block of ACTIVE rTMS. Each block will consist of daily sessions of active rTMS delivered to the left dorsolateral prefrontal cortex over ten days (Monday through Friday).

  • Sham rTMS

    Device

    All study participants will receive one block of SHAM rTMS. Each block will consist of daily sessions of SHAM rTMS delivered to the left dorsolateral prefrontal cortex over ten days (Monday through Friday).
