Am I a candidate for Focused Ultrasound?

  • Should I try medications first?

    The first line of treatment for Essential Tremor is medications. If you have a confirmed diagnosis of essential tremor and prescribed medications (such as propranolol or primidone) have not provided satisfactory tremor improvement, you may be a candidate for Focused Ultrasound.

  • If I have tremor in both hands, do I need two treatments, one for each hand?

    The Focused Ultrasound treatment is FDA approved for unilateral treatment – treating one side, usually the dominant hand.

Risks and Side Effects

  • What side effects can I expect during the treatment?

Insightec-sponsored clinical studies have shown that the most common side effects are imbalance/gait disturbance, numbness/tingling and headache/head pain. Additional infrequent events include dizziness, taste disturbance, slurred speech, fatigue and vomiting. For more on safety information, click the link below.

During and After Treatment

  • Why do I have to be awake during the treatment?

    Your feedback is necessary as you will be asked to do tasks such as drawing spirals. This is so the physician can evaluate the improvement of your tremor and identify any potential side effects that you may be experiencing during the treatment.

  • How long do I have to stay for the treatment during and after?

    The average treatment time is 2.5 hours. The treatment is usually performed on an outpatient basis; however the treating physician will decide when you can return home.

  • Will my tremor return?

    There is the possibility that your hand tremor may return months or even years after the Focused Ultrasound treatment, or that the tremor may not improve at all. And while the treatment may improve your tremor, it’s important to understand that it does not treat the underlying disease nor prevent its progression.

  • How soon can I return to work after the treatment?

    That depends on the type of work that you do and how you feel. Please consult with your physician.
