Tremor | Stereotactic Radiosurgery for Essential Tremor and Parkinsonian Tremor
Tremor research study
What is the primary objective of this study?
The purpose of this study is to determine the changes in quality of life and degree of tremor for patients with essential tremor or Parkinsonian tremor who are treated by stereotactic radiosurgery (SRS). This is a questionnaire-based study. Please see Detailed Description below for more information.
Who is eligible to participate?
Inclusion Criteria: - Must be certified by a neurologist as having essential tremor or Parkinsonian tremor that is insufficiently controlled by medication alone. - Preference to receive radiation treatment for tremor treatment, rather than surgical DBS implantation or surgical thalamotomy - At least 18 years old Exclusion Criteria: - Contraindications to cranial radiation (such as prior radiation to the thalamus) - Inability to have a MRI of the brain - Prior surgical thalamotomy treatment (but contralateral deep brain stimulator [DBS] is permitted) - Estimated life expectancy less than 1 year
Which medical condition, disease, disorder, syndrome, illness, or injury is researched?
Quality of Life
Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.
Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.
