Brief Summary:
Executive function deficits are common in late life depression (LLD) and are associated with resistance to antidepressants, poor quality of life, considerable disability and increased suicidal risk. This study uses a novel type of Transcranial Magnetic Stimulation called intermittent Theta Burst Stimulation (iTBS). iTBS delivers high frequency (50Hz) magnetic pulses in "bursts" of 3 stimuli. It is posited that this intervention induces plasticity in the human cortex. Theoretical and empirical evidence from research studies informs that iTBS can improve depression and executive deficits, however, this has not been examined in older adults.
This project examines iTBS's ability to improve depression and executive impairment in LLD. It also tests the effects of iTBS on brain connectivity within the Cognitive Control Network (CCN). This study will enhance understanding of LLD, providing critical pilot data to develop future randomized controlled clinical trials.
Both active and sham interventions are administered sequentially to the left and right dorso-lateral prefrontal cortex. The total stimulation time is about 7 minutes. These interventions are administered for 6 weeks (Monday-Friday). 20 subjects will be randomized. Changes in mood from baseline to the end of study are measured with the Montgomery-Asberg Depression Rating Scale. Executive function at baseline and end of study are evaluated with the National Institutes of Health Toolbox executive domain battery. Safety assessments include: the 21 item Scale for suicidal ideation SSI. The frequency, intensity and burden of side effects rating (FIBSER) and the Altman Self Rating Mania scale (ASRM). Ancillary depression measures include the Quick Inventory of Depressive Symptoms (QIDS) and the Clinical Global Impression of Improvement scale.
Subjects undergo functional Magnetic Resonance Imaging (fMRI) before and after the study interventions to test the effects of iTBS on the brain's functional connectivity.
This research will provide meaningful information about the effects of iTBS on mood and executive function in older adults as well as information regarding its effects on brain function. Results of this pilot study will inform a grant submission and allow investigators to calculate power for a definitive randomized controlled clinical trial to test the efficacy of iTBS versus placebo.
