rTMS to Improve Cognition in Parkinson's (TMSCogReP)
Parkinson's Disease, Mild Cognitive Impairment
About this trial
This is an interventional treatment trial for Parkinson's Disease focused on measuring rTMS, Parkinson's disease, mild cognitive impairment, executive function, neuromodulation, functional connectivity
Eligibility Criteria
Inclusion Criteria:
- Veterans who seek services at Hines VA Hospital or Jesse Brown VA Medical Center
- Diagnosis of PD as determined by the UK Parkinson's Disease Society Brain Bank Diagnostic Criteria
- Meet criteria for having mild cognitive impairment
- Receiving stable (i.e., no changes in medication and medication dose) medication and who are expected to remain on stable medication for the duration of the RCT
- Speak and read English
- 50 years or older
Exclusion Criteria:
- Dementia
- Failure to demonstrate decision making capacity
- History of deep brain stimulation surgery
- Severe depression
- Resting head tremor
- Dyskinesia that will interfere with collecting imaging data
- Has congestive heart failure
- Implanted cardiac pacemaker or defibrillator
- Cochlear implant, nerve stimulator, or intracranial metal clips
- Implanted medical pump
- Increased intracranial pressure
- History of claustrophobia
- Metal in eyes/face, shrapnel/bullet remnants in brain
Participants at potential increased risk of seizure including those who have the following:
- history (or family history) of seizure or epilepsy
- history of stroke, head injury, or unexplained seizures
presence of other neurological disease that may be associated with an altered seizure threshold
- such as CVA, cerebral aneurysm, dementia, increased intracranial pressure
- Concurrent medication use such as tricyclic antidepressants, neuroleptic medications, any other drug known to lower seizure threshold
- Secondary conditions that may significantly alter electrolyte balance or lower seizure threshold
- No quantifiable motor threshold such that rTMS dosage cannot be accurately deter-mined
Sites / Locations
- Jesse Brown VA Medical Center, Chicago, IL
- Edward Hines Jr. VA Hospital, Hines, ILRecruiting
Arms of the Study
Arm 1
Arm 2
Experimental
Sham Comparator
active rTMS
sham rTMS
For active rTMS, a butterfly coil and MagVenture MagProX100 stimulator (MagVenture, Falun, Denmark) will be used. One rTMS session will consist of 40 trains of 5sec each at 110% of resting motor threshold and 15Hz will be provided at the left DLPFC.
For sham rTMS, the procedure will be carried out at the left DLPFC but a sham coil will be used. The MagVenture coil has an active side and a placebo side allowing a double-blind study to be conducted. The sham system looks, sounds and feels like active rTMS.
