Summary

The goal of this study is to determine whether transcranial magnetic stimulation (TMS) is an effective treatment in Parkinson's disease patients with depression or cognitive impairment. The study consists of seven total visits to all. Compensation will be provided for each visit.

Detailed description

Transcranial magnetic stimulation(TMS) is a valuable non-invasive brain stimulation tool for interventional neurophysiology applications, which generate local current and modulates brain activity in a specific, cortico-subcortical network. Repetitive TMS (rTMS) is developed as it is safe and well-tolerated. The left dorsolateral prefrontal cortex (DLPFC) high-frequency rTMS treatment has been proved effective for depression by many clinical studies,as well as the low-frequency rTMS over the right DLPFC. In Europe, guidelines on the therapeutic use of rTMS was published in 2014, in which they pointed out that high-frequency rTMS over left DLPFC could be used as therapeutic method for dPD, with a B-level recommendation. Among several small and pilot studies of rTMS in PD patients, rTMS over either the motor cortex or DLPFC has been reported to show beneficial effects on cognitive impairment with no serious adverse events.However, the relative effectiveness of rTMS over left or right prefrontal, or both regions on both depression and cognitive impairment symptoms, has yet to be established in PD patients. The investigators propose to conduct a ten-center, blinded, sham-controlled, randomized, parallel-group study of fixed-dose, high-frequency and/or low-frequency rTMS in 252 PD patients who are experiencing depressive symptoms or cognitive impairment. Subjects will be randomized to receive rTMS over right and left DLPFC, both or neither active/sham rTMS. Subjects will receive rTMS for 45 minutes treatment over a 2-week period, all subjects will undergo a comprehensive assessment of mood, cognition, motor and quality of life before and after the last rTMS treatment, and after 2,4 and 12 weeks post-treatment. This study directly addresses the expansion of rTMS as an alternative treatment for depression and cognitive impairment in the PD population.

Interventions

Type	Name	Description
DEVICE	repetitive transcranial magnetic stimulation(rTMS)	Each patient will be given 5 treatment sessions per week for 2 weeks (a total of 10 sessions).In each rTMS conditioning session,1200 pulses of stimuli at an intensity of 100% rest motor threshold (RMT) will give over the left and rigt DLPFC.Each session is 45 minutes long and will be consisted of 10Hz stimulation trains (active) over the left DLPFC and 1Hz over the right DLPFC，Interval of 5 minutes each side.During rTMS blocks, the coil will be oriented tangential to the surface. For sham control rTMS blocks, the coil will be oriented 90◦ away from the scalp so that no pulses perturbed underlying neural tissue.
