The Effect of Repetitive Transcranial Magnetic Stimulation on the Cognition in People With Parkinson's Disease

March 31, 2021 updated by: Chien Tai Hong, Taipei Medical University Shuang Ho Hospital
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.

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The present trial is designed as an open-label, uncontrolled pilot study for evaluating the effect of rTMS on cognitive function in people with Parkinson disease (PD). The primary endpoint is the change of cognitive function, and the secondary endpoint is the improvement of motor symptoms. All participants need to complete the informed consent before they are enrolled into the trial. Preliminary data including age, sex, education, employment, medical history, drug history, disease duration, modified Hoehn-Yahr stage, and UPDRS score are collected. Cognitive function including mini-mental state examination (MMSE), clocking drawing test, Wechsler memory scale (WMS)-world list test and spatial span test, trial making test A and B, category fluency test (animal naming), and beck depression inventory-II are tested by trained neuropsychiatrists. Gait function are evaluated with time up and go (TUG), freezing of gait questionnaire (FOG-Q), and Gait-up device analysis before trial starting. Pre-treatment brain image examined by magnetic resonance image (MRI) and blood sampling for synapse protein level are performed. The participants are then arranged to receive theta burst stimulation for 5 days by using Magstim machine (Super Rapid 2) equipped with air cooled coil (D70), stimulating on supplementary motor area (SMA). After the intervention, post-treatment evaluation including cognition, motor symptoms, gait function, brain MRI, and blood sampling will be performed again with the same methods at 1 month later. Any adverse event during the trial period will also be recorded. The trial is expected to be conducted in Shuange-Ho hospital, Taipei Medical University.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
