Standardization and Optimization of TMS Protocols for the Treatment of Early and Mild-to-late Stage Parkinson's Disease With Depression or Cognitive Impairment

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.

Study Overview

• Status: Unknown
• Conditions: TMS Protocols in the Treatment of PD
• Intervention / Treatment: Device: repetitive transcranial magnetic stimulation(rTMS)

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Hamilton Depression Scale（HAMD）	The Hamilton Depression Rating Scale (HAMD) is a 24-item interviewer administered structure questionaire designed to assess symptoms of depression. Items are scored with a range of 0-4, though 11 of the items are scored between 0 and 2. A total score is then calculated of all items which can range from 0 to 74. A higher score is indicative of more depressive symptoms, and a lower score post-tx is indicative of better outcome.	3 months
Beck Depression Inventory（BDI）	The Beck Depression Inventory (BDI) is a 21-item self-report questionaire that measures depressive symptoms. Each item is scored on a scale of 0-3, and items are summated to yield a total score. A higher score is indicative of greater symptoms of depression. Total scores may range between 0 and 63. A score greater than or equal of 14 is suggestive of clinically significant symptoms.	3 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Mini-mental State Examination（MMSE）	The MMSE consists of 2 parts: language (time orientation (5 items), registration and attention) and performance (recall, response to written/verbal commands, sriting ability and reproduction of complex polygons); the total score can range from 0 to 30, with a higher score indicating better function. A positive change score indicates improvement from baseline.	3 months
Montreal Cognitive Assessment Scale（MoCA）	The MoCA explores 8 cognitive domains: visuospatial/executive (score range form 0 to 5), naming(0-3), attention (0-5), language (0-3), abstraction(0-2), delayed recall(0-5), and orientation(0-6). The MoCA score was not corrected according to education level as advised by Gagnon and colleagues (2013). Its normal value was≥26 as proposed. A lower score indicates more severe cognitive impairment.	3 months
Named test of the Aphasia Battery of Chinese	The Aphasia Battery of Chinese(ABC) was compiled by Surong Gao et al in 1988 in accordance with the basic principles of aphasia inspection.It is mainly based on the Western Aphasia Battery (WAB), which has been developed through exploration and modification in combination with Chese national conditions and clinical experience.The named test is one of the subtest of the ABC.A total score is then calculated of all items which can range from 0 to 82. A higher score is indicative of worse outcome.	3 months
Similarity test	The similarity test includes 13 items scored with a range of 0-2. In each item, participants are given two words or concepts and have to describe how they are similar. A lower score indicates more severe abstract verbal reasoning and semantic knowledge impairment.	3 months
Symbol Digit modalities test（SDMT）	The Symbol Digit modalities test（SDMT) consists of nine digit-symbol pairs followed by a list of digits. Under each digit the subject should write down the corresponding symbol as fast as possible. The number of correct symbols within the 90 sec is measured.	3 months
Verbal fluency test（VFT）	The verbal fluency test is a kind of psychological test in which participants have to produce as many words as possible from a category in a given time (usually 60 seconds). A 60-second limit for responses within each category was allowed. Higher scores represent better performance.	3 months
Logical memory test（LMT）	The Logical Memory, subtest of the WMS-R is a standardized assessment of narrative episodic memory. A short story is orally presented, and the examinee is asked to recall the story immediately.	3 months
Delayed memory test（DMT）	Approximately 5 and 30 min later of the Logical memory test, recall of the story is again elicited, which is called delayed memory test.	3 months
Digit span test（DST）	In digit span test, participants must recall a series of numbers in order. A lower score indicates more severe working memory, attention, encoding and auditory processing impairment.	3 months
Ten point clock test	The ten point clock test is a reliable test of cognitive function. A total score is then calculated of all items which can range from 0 to 10. A higher score is indicative of better outcome.	3 months
Uniform Parkinson's Disease Rating Scale Ⅲ（UPDRSⅢ）	The motor section of the Unified Parkinson Disease Rating Scale (UPDRSⅢ) is covers the motor evaluation of disability and includes ratings for tremor, slowness (bradykinesia), stiffness (rigidity), and balance; part IV covers a number of treatment complications including ratings of involuntary movements (dyskinesias), painful cramps (dystonia), and irregular medication responses (motor fluctuations). It consists of 27 items, each are scored with a range of 0-4, with total score ranges from 0 to108. A higher score is indicative of more severe motor symptoms.	3 months
Modified Hoehn & Yahr scale（H-Y）	The Hoehn&Yahr scale is a commonly used system for describing how the symptoms of Parkinson's disease progress. It was originally published in 1967 in the journal Neurology by Melvin Yahr and Margaret Hoehn and included stages 1 through 5. Since then, a modified Hoehn&Yahr scale was proposed with the addition of stages 1.5 and 2.5 to help describe the intermediate course of the disease. A higher score is indicative of more severe movement impairment.	3 months
Time up and go test（TUG test）	The Timed Up and Go Test is well known and widely used where the clinical goal is to get an accurate objective assessment of balance. It measures the time taken by an individual to stand up from a standard arm chair, walk a distance of 3 meters, turn, walk back to the chair, and sit down.	3 months
Activity of Daily Living Scale（ADL）	ADL was developed by Lawton and Brody in 1969.It consists of Physical self-maintenance Scale (PSMS) and Instrumental Activities of Daily Living Scale (IADL).It is mainly used to assess the daily life ability of the subjects. The total score below 14 points is indicative normal.More than 16 points is indicative functional decline.The highest score is 56.	3 months
Parkinson's Disease Questionnaire（PDQ-39）	The Parkinson's Disease Questionnaire is designed to address aspects of functioning and well-being for those affected by Parkinson's disease. Substantial evidence is available to suggest that the PDQ is reliable, valid, responsive, acceptable and feasible as the tool for the assessment of quality of life in Parkinson's disease patients. There are 39 questions in the long form Parkinson's Disease Questionnaire, with 8 discrete scales:mobility (10 items),activities of daily living (6 items),emotional well-being (6 items),stigma (4 items),social support (3 items),cognitions (4 items),communication (3 items),bodily discomfort (3 items) . Items are scored with a range of 0-4. A total score is then calculated of all items which can range from 0 to 156. A higher score is indicative of worse outcome.	3 months
Non-motor symptoms questionnaire(NMS-Q)	The non-motor symptoms (NMS) questionnaire can be given to people affected by Parkinson's in order to aid health and social care professionals to assess their non-motor symptoms.The non-motor symptoms questionnaire is a 30-point, patient-based questionnaire used to determine the non-motor symptoms experienced by the patient during the past month. The points should be totalled to give a score out of 30. A score of under 10 is mild, 10-20 moderate and over 20, severe.	3 months
Pittsburgh Sleep Quality Index (PSQI)	The Pittsburgh Sleep Quality Index (PSQI) is an effective instrument used to measure the quality and patterns of sleep in adults. It differentiates "poor" from "good" sleep quality by measuring seven areas (components): subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medications, and daytime dysfunction over the last month. A total score is then calculated of all items which can range from 0 to 21. A higher score is indicative of worse outcome.	3 months
Hamilton Anxiety Scale（HAMA）	The Hamilton Anxiety Rating Scale (HAMA) is a designed to assess symptoms of anxiety. Items are scored with a range of 0-4. A total score is then calculated of all items which can range from 0 to 54. A higher score is indicative of more anxiety symptoms, and a lower score post-tx is indicative of better outcome.	3 months
Beck Anxiety Inventory（BAI）	The Beck Anxiety Inventory (BAI) is a 21-item self-report questionaire that measures Anxiety symptoms. Each item is scored on a scale of 0-3, and items are summated to yield a total score. A higher score is indicative of greater symptoms of anxiety. Total scores may range between 0 and 63. A score greater than or equal of 8 is suggestive of clinically significant symptoms.	3 months
