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.

Further study details as provided by Austin Kirschner, Vanderbilt University:

Primary Outcome Measures:
  • Quality of Life [ Time Frame: 1 year ]
    The tremor-related quality of life for each patient will be assessed by self-assessment questionnaire at 3 month intervals for 1 year after treatment by stereotactic radiation.

Secondary Outcome Measures:
  • Severity of Tremor [ Time Frame: 1 year ]
    The severity of tremor will be assessed by objective measure (Fahn-Tolosa-Marin tremor rating scale) at 3 month intervals for 1 year following the stereotactic radiation treatment.

  • Neuropsychological Assessment [ Time Frame: Baseline and 6 months post-treatment ]
    All patients will undergo a neuropsychological assessment (1-2 hr examination) at baseline and at 6 months post-treatment. This will assess any unanticipated changes in neuropsychological brain function.

Estimated Enrollment: 30
Study Start Date: November 2012
Estimated Study Completion Date: November 2018
Estimated Primary Completion Date: November 2017 (Final data collection date for primary outcome measure)
  Show Detailed Description


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
This trial enrolls persons with essential tremor or Parkinsonian tremor that is inadequately controlled by medications.

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
