Brief summary
The purpose of this study is to test the effects of low frequency deep rTMS using the novel H-coil on the motor, affective and cognitive deficits in patients with asymmetric Parkinson's disease (PD), to establish its safety in this population and to test effects of maintenance treatments.
Detailed description
PD patients with asymmetric disease aged 40 years or older, diagnosed as idiopathic PD according to the UK Brain Bank criteria, with Hoehn & Yahr stages II - IV while off will be recruited. Participants on antidepressants should be at least 2 months on stable therapy. Patient will be excluded if: 1. Patients who have concomitant epilepsy, a history of seizure or heat convulsion or history of epilepsy in first degree relative. 2. Patients on neuroleptics. 3. Patients with unstable medical disorder. 4. History or current unstable hypertension. 5. History of head injury or neurosurgical interventions. 6. History of any metal in the head (outside the mouth). 7. Known history of any metallic particles in the eye, implanted cardiac pacemaker, implanted neurostimulators, surgical clips (above the shoulder line) or any medical pumps. 8. History of migraine or frequent or severe headaches. 9. Current hearing loss. 10. The presence of cochlear implants 11. Current drug abuse or alcoholism. 12. Pregnancy or not using a reliable method of birth control. 13. Participation in current clinical study or clinical study within 30 days prior to this study. Patients will be to randomized to an active rTMS arm or to a sham stimulation arm. Each patient will be given 12 stimulation sessions, over a period of 4 weeks, and then a maintenance phase consisting of 8 stimulation sessions for the first 4 weeks and additional 4 stimulation sessions during the following 4 weeks. Active treatment with the H-coil will include stimulation over the motor cortex (1 Hz stimulation 110% of the motor threshold for 15 minutes) and over the prefrontal cortex (10Hz stimulation 100% of the motor threshold, 2 seconds each train, 20 seconds between trains, for 15 minutes). The control arm group will receive sham stimulations in identical treatment and maintenance schedules. Patients from the sham group who will complete the study will be given the opportunity to receive 12 sessions of real r-TMS treatment over 4 weeks as the treatment group. The following outcome measures will be taken prior to the treatment (screening visit), and at day 1, 10, 30, 60 and 90. Evaluation will be while subjects are both at on and off. Motor: 1. Unified Parkinson's Disease Rating Scale (UPDRS ) 2. Clinical Global Impression of Severity (CGIS) 3. Pegboard test. 4. Tapping test 5. Up & Go test 6. Abnormal Involuntary Movement Scale (AIMS) Mood and affect 1\. Beck Depression Inventory (BDI) Cognition 1. Mini mental State examination (MMSE) 2. Digit forward and backward tests. 3. Word fluency. 4. Frontal Assessment Battery (FAB) Side effects will be closely monitored by the researchers and will be promptly reported to the IRB.
Interventions
Active treatment with the H-coil will include stimulation over the motor cortex (1 Hz stimulation 110% of the motor threshold for 15 minutes) and over the prefrontal cortex (10Hz stimulation 100% of the motor threshold, 2 seconds each train, 20 seconds between trains, for 15 minutes).
