What is the purpose of a Thalamotomy?

Thalamotomy is a surgical procedure used to treat tremor. It involves destroying a tiny area in a part of the brain called the thalamus. The area which has been destroyed is called a ‘lesion’.

What is Thalamotomy and for which disorder is it used as treatment?

Thalamotomy is rarely done today. It may be used to treat severe tremor on one side of the body (most often in an arm or leg) that does not respond to medicines. It does not help with slow movement (bradykinesia), speech problems, or walking difficulties.

Why would Deep brain stimulation DBS be a preferred treatment method compared to Thalamotomy in a Parkinson’s patient?

Conclusions: Thus, the flexibility of DBS for tremor control and complication avoidance makes it superior to thalamotomy for tremor control at the expense of equipment cost and continual management.

What does a thalamic stimulator do?

A thalamic stimulator is a medical device that can suppress tremors, such as those caused by Parkinson’s disease or essential tremor. It was approved for use by the Food and Drug Administration (FDA) on August 4, 1997.

How is a thalamotomy performed?

Thalamotomy can be performed without incisions using ultrasound waves. The ultrasound waves are focused to the thalamus, thus cause thalamotomy through an intact skull. This procedure uses MRI guidance to localize the thalamus.

What is deep brain stimulation for Parkinson’s?

Deep brain stimulation (DBS) delivers electrical impulses to a targeted area of the brain that is responsible for the movement symptoms (also called motor symptoms) caused by Parkinson’s disease. The electrical impulses disrupt the abnormal activity that occurs in the brain’s circuitry, which is causing the symptoms.

Who is a good candidate for deep brain stimulation?

Criteria for Deep Brain Stimulation Surgery An ideal candidate for DBS surgery is under 70 years old and is in good health. Patients who fluctuate between “on” and “off” medication states are usually good surgical candidates, as are those who have troublesome dyskinesias.

What are the disadvantages of deep brain stimulation?

Side effects associated with deep brain stimulation may include:

  • Seizure.
  • Infection.
  • Headache.
  • Confusion.
  • Difficulty concentrating.
  • Stroke.
  • Hardware complications, such as an eroded lead wire.
  • Temporary pain and swelling at the implantation site.

What is medial to the thalamus?

The medial surface of the thalamus constitutes the upper part of the lateral wall of the third ventricle, and is connected to the corresponding surface of the opposite thalamus by a flattened gray band, the interthalamic adhesion.

What is stereotactic thalamotomy?

Stereotactic thalamotomy works by destroying part of the thalamus to block the abnormal brain activity from reaching the muscles and causing tremor.

Is brain stimulation good for Parkinson’s disease?

For example, deep brain stimulation of subthalamic nucleus is effective for all major movement symptoms of Parkinson’s disease, such as tremor, slowness of movement (bradykinesia), stiffness (rigidity), and problems with walking and balance.
