Brief Summary
The purpose of this study is to evaluate the blood brain barrier in the striatum of patients that have other types of movement disorders compared to patients with Parkinson's Disease that are receiving similar treatment, to determine if a there is a disruption of the blood brain barrier in patients with Parkinson's Disease.

Outcome Measures
Primary Outcomes (1)
Degree of contrast enhancement
Pre-contrast images will be used as mask images and will be digitally substracted from post-contrast images to obtain the "difference" images. From the "difference images", two neuroradiologists blinded to the clinical status of the patient will assess the degree enhancement in the striatum (none,mild, moderate, marked).
one year
Secondary Outcomes (1)
Permeability of blood brain barrier in the striatum
one year
Study Arms (2)
Parkinson's disease group
* patients diagnosed with Parkinson's disease by a movement disorder specialist from the deep brain stimulation program at The Ottawa Hospital, Civic Campus * to undergo pre-operative MRI with contrast
Control group
* patients diagnosed with either essential tremor or cervical dystonia by a movement disorder specialist from the deep brain stimulation program at The Ottawa Hospital, Civic Campus * to undergo pre-operative MRI with contrast
Eligibility Criteria
Patients having movement disorders undergoing deep brain stimulation (DBS) of the internal segment of the globus pallidus for treatment of motor symptoms refractory to medical therapy at the Ottawa Hospital, Civic Campus, will be recruited to participate in this pilot study. The cohort will include 10 PD patients and 10 control subjects. The PD subjects will have received a diagnosis of PD using established clinical criteria following clinical assessment at the Movement Disorders Clinic of The Ottawa Hospital. The 10 control subjects will consist of those undergoing DBS and assessed in the same clinic with a clinical diagnosis of either essential tremor or cervical dystonia.
You may qualify if:
- Disease burden is dominated by motor symptoms such as rigidity, bradykinesia, akinesia, and tremor;
- Medications have been optimized by a movement disorder neurologist;
- Adequate social support to assist with preoperative recovery and problems during subsequent programming;
- No major mood disorder and any mood disorders are medically optimized;
- No major cognitive impairment;
- No underlying medical conditions that would preclude surgery;
- Adequate response to levodopa, as assessed by UPDRS-3 on and off levodopa. All participants has at least a 30% improvement;
- eGRF\>30
You may not qualify if:
- Disease burden is not dominated by motor symptoms such as rigidity, bradykinesia, akinesia, and tremor;
- Medications have not bee optimized by a movement disorder neurologist;
- There is not adequate social support to assist with pre-operative recovery or problems during subsequent programming;
- Presence of major mood disorders or any mood disorders not medically optimized;
- Presence of major cognitive impairment;
- Presence of underlying medical conditions that would preclude surgery;
- Inadequate response to levodopa;
- eGFR\<30
