NCT04698928
Parkinson's disease (PD) is the second most common neurodegenerative disease. The cardinal symptoms of PD are tremor, rigidity, bradykinesia and postural instability. Cognitive impairment and dementia are also one of the key features of the non-motor symptoms of PD. At present, the mainstream treatment of PD-dementia is the dopaminergic rivastigmine. Repetitive transcortical magnetic stimulation (rTMS) is a novel non-invasive intervention. Through the magnetic stimulation, brain neurons could be activated by the electrical current. The application of rTMS had been approved by US FDA for the treatment of depression. The possible effect of rTMS may result from the stimulation-related neuronal plasticity. Regarding PD, rTMS also had been found to had some effect on different motor symptoms and cognition. The present study would like to test the accumulative effect of rTMS on cognition of PD. All the study subjects will receive rTMS under intermittent theta burst stimulation (iTBS) mode at supplementary motor area (SMA). Cognitive bahevorial tests and other motor/depression assessments will be assessed before and after the intervention.

PLUG Dementia Trial: Patients will be screened at Intermountain Medical Center and at Intermountain affiliated anticoagulation clinics in the Salt Lake City region. Patients with atrial fibrillation that undergo a standard of care, clinically approved, left atrial appendage closure will be considered for study. All patients will be followed for 24 months, and will be assessed at the 3-, 6-, 12-, 18- and 24-months post-left atrial appendage closure as well as other visits deemed necessary for clinical care. All subjects will undergo protocol-specified laboratory tests and will complete 6 standard, validated questionnaires at each follow-up visit, except at the 3-month visit when only one questionnaire will be administered. A subset of patients (n=20), will receive a cranial MRI at baseline and 24-month visit. MRI PLUG Dementia Sub-Study: In addition to the above, 20 of the 60 subjects who are selected for participation in this sub-study will receive a cranial MRI at baseline and at the 2-year (24 months) follow-up visit.
