Accelerated rTMS for Parkinson's Disease
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial investigates whether a non-invasive treatment called repetitive transcranial magnetic stimulation (rTMS) can improve movement and thinking in people with Parkinson's disease. rTMS uses magnetic pulses to stimulate brain areas, focusing on the motor cortex, which controls movement. The trial targets individuals with mild to moderate Parkinson's who experience movement issues and possibly memory or thinking problems. Participants must have maintained a stable medication routine for at least four weeks and be willing to attend multiple sessions at the San Francisco Neurology and Sleep Center. As an unphased trial, this study offers participants the chance to contribute to groundbreaking research that could enhance understanding and treatment of Parkinson's disease.
Do I need to stop my current medications for the trial?
No, you do not need to stop your current medications. Participants must maintain stable doses of their anti-parkinsonian medications for at least 4 weeks before the trial and throughout the study period.
What prior data suggests that this rTMS treatment is safe for Parkinson's disease?
Research has shown that repetitive transcranial magnetic stimulation (rTMS) is generally safe for people with Parkinson's disease. Studies have found it can improve movement and thinking skills without causing major side effects. For instance, a review of several studies found that rTMS effectively eases movement problems in people with Parkinson's. Other research confirms that rTMS is a safe and noninvasive treatment with promising potential as an additional therapy for managing Parkinson's disease. Participants in these studies did not report any major negative effects, suggesting that rTMS is well-tolerated.12345
Why are researchers excited about this trial?
Unlike the standard treatments for Parkinson's disease, such as levodopa or dopamine agonists, accelerated rTMS (repetitive transcranial magnetic stimulation) offers a non-invasive approach that uses magnetic fields to stimulate nerve cells in the brain. Researchers are excited about this treatment because it targets the primary motor cortex directly, which might help improve motor function more effectively. Additionally, this method can be appealing because it potentially reduces reliance on medications, which often come with a range of side effects. By offering a new mechanism of action and delivery method, accelerated rTMS could provide a promising alternative for managing symptoms of Parkinson's disease.
What evidence suggests that accelerated rTMS is effective for Parkinson's disease?
Research has shown that repetitive transcranial magnetic stimulation (rTMS) can help treat Parkinson's disease (PD). A review of several studies found that rTMS improves movement and thinking in people with PD. In this trial, participants will receive rTMS treatment targeting the brain area that controls movement, which research indicates can greatly enhance motor skills. Another study found that rTMS provides moderate benefits for walking and overall motor function. Overall, rTMS appears to be a promising and safe method to enhance movement and cognitive abilities in PD.12567
Are You a Good Fit for This Trial?
This trial is for people aged 50 to 90 with mild to moderate Parkinson's disease, who are on stable medication doses and can attend all study visits. Participants need a caregiver or partner to help provide information and must be able to complete movement and thinking tests.Inclusion Criteria

Active Control
Participants with mild to moderate idiopathic Parkinson's disease (Hoehn and Yahr stage 1-3) receive 6 sessions of high-frequency repetitive transcranial magnetic stimulation (rTMS) using the EXOMIND™ device (BTL-699-2), administered twice weekly over approximately 3 weeks. Each session delivers bilateral stimulation to the primary motor cortex (M1) at 10-20 Hz and 90-110% of resting motor threshold, with 3,000-6,000 total pulses per session. Participants maintain their stable pre-study anti-parkinsonian medication regimen throughout the study. Motor function (MDS-UPDRS-III, Freezing of Gait Questionnaire, Timed Up and Go Test, gait speed), cognitive function (Montreal Cognitive Assessment, Creyos cognitive battery), depressive symptoms (PHQ-9), and quality of life (PDQ-39) are assessed at baseline, last treatment session, 1-month follow-up, and 3-month follow-up.
