Clinical Trial Summary

The purposes of this research are to test whether it is feasible to administer a treatment protocol called intermittent theta burst stimulation (iTBS) repetitive transcranial magnetic stimulation (rTMS) in adults with mild cognitive impairment (MCI), and to test whether iTBS rTMS treatments can improve memory in mild cognitive impairment (MCI).

Description:

To test the feasibility of conducting a 10-day Intermittent Theta Burst Stimulation (iTBS) repetitive Transcranial Magnetic Stimulation (rTMS) protocol twice using a cross-over design in individuals with Mild Cognitive Impairment (MCI), pilot test the study protocol to assess study design, and collect pilot data on the effect of stimulations over 3 different brain regions (left dorsolateral prefrontal cortex (DLPFC), lateral parietal cortex (LPC), vertex) on working memory, new-learning and executive function in MCI. Neuropsychological and sleep measures, functional brain magnetic resonance imaging (fMRI), high density EEG and questionnaires will be performed at 5 timepoints - baseline, post-treatment after first period of 10 daily iTBS rTMS sessions, post-washout period of 4 weeks, post-treatment after cross-over to second period of 10 daily iTBS rTMS sessions, and 4 weeks follow-up post-treatment.
