Transcranial Magnetic Stimulation for Apathy in MCI

Start: November 1, 2018
End: September 2023
Enrollment: 125

What Is This Study About?

In this multi-phase study, researchers are investigating the effects of transcranial magnetic stimulation (TMS) on motivation, memory, and function in older veterans with mild memory problems. TMS is a noninvasive procedure that involves the use of magnetic fields to stimulate areas of the brain. Participants will undergo either real or sham magnetic stimulation to the front part of their brain over 20 sessions. Researchers will measure changes in function, qualify of life, and rates of progression to dementia over a two-year period. Genetic testing and biomarkers will be used to differentiate those who respond to magnetic stimulation from those who do not.
