La description
Inclusion Criteria:
- Confirmed clinical diagnosis of ET
- Isolated tremor syndrome, at least 3 years duration
- Subjective complaint of tremor assessed and validated by physician
- Must be willing to comply with the study protocol
- English Proficiency
- At least 18 years of age
- At most 90 years of age
Exclusion Criteria:
- Severe microvascular disease or structural brain lesions equivalent to Fazekas scale of 3 or higher in the periventicular or deep white matter.
- Subjects on blood thinning medications (e.g. Eliquis)
- Recent stroke (within the last 6 months)
- Implanted electrodes (e.g. DBS) in brain
- History of aneurysm
- History of cranial trauma resulting in fracture or traumatic brain injury
- Subjects who are unable to cooperate with the testing.
- Subjects who lack capacity to consent
- Subjects with severe cardiac disease, increased intracranial pressure, or using a transcutaneous electrical nerve stimulation (TENS) unit.
Severe cardiac disease will be defined as any of the following:
i) History of myocardial infarction within the past 6 months ii) Diagnosis of congestive heart failure with NYHA Class III or IV symptoms iii) History of unstable angina, life-threatening arrhythmias, or use of an implantable cardioverter-defibrillator (ICD) iv) Uncontrolled hypertension (SBP >180 mmHg or DBP >110 mmHg) despite medication v) Any condition judged by the study physician to place the subject at increased risk from study participation
- Subjects with implanted medical devices
- Subjects with a history of seizure disorder.
- Subjects with contraindications to enter MRI environment
- Subjects with a history of substance abuse.
- Subjects who are currently pregnant. This will be verified by a urine test prior to beginning the study.
