RecruitingDevice studyTranscranial Pulse Stimulation of the BrainThis study will investigate transcranial pulse stimulation (TPS) as a method of enhancing cognitive and neural function. The study team will apply this low intensity, magnetically pulse technology to key brain regions in a randomized, sham-controlled trial (RCT). The study will determine the magnitude of changes in cognitive function and brain function and structure between a pre- and post-stimulation among 10 typically-aging older adults and 10 patients with mild dementia.
