Since the procedure is done in an MRI scanner, there is a weight limit, generally in the range of 350 lbs. Patients will need to undergo a CT scan to determine if they are candidates for treatment. The severity of your tremor and your overall health will be evaluated as part of the evaluation process. Your doctors will also want to be sure you have tried at least two medications and found that they do not help you and/or have undesirable side effects. You must have a confirmed diagnosis of essential tremor or tremor dominant Parkinson’s disease to be referred for an MR-guided focused ultrasound. Within days you should be able to return to normal activities. The physician will let you know when you can go home. The procedure will last approximately between 3-4 hours.Īfter the procedure, you'll be transferred to a recovery room for a short monitoring period. At the end of the procedure, a final MRI scan will be done to assess the treatment. It is common to experience a noticeable reduction in tremor during the procedure itself.
The treating neurosurgeon will then apply higher energy to create the permanent lesion. The team will continue to fine-tune the therapy and identify any side effects. Tasks may include drawing spirals on a board or performing tasks with your hands. After each application of energy, called a sonication, you will be asked to perform specific tasks to evaluate your tremor improvement. The treating neurosurgeon will first apply light doses of ultrasound energy and real-time images of the ultrasound delivery will be taken.
#Focused ultrasound for essential tremor series
A series of MRI images will be taken for planning the treatment according to your specific anatomy. You will then lie down in the MRI scanner equipped with the focused ultrasound machine. You will also be given a “stop sonication” button to indicate to the physician that you want to stop the treatment for any reason. You may be given additional medication to keep you comfortable. Your heart rate, blood pressure, and blood oxygen levels will be monitored throughout the procedure. Cool water will circulate in the helmet around the top of your head to minimize potential heating near the scalp. Local anesthesia will be applied to numb areas of your scalp, and a frame will be secured to your head so that your head doesn’t move during the treatment.

Often prescribed are anti-seizure medications, beta-blockers, Botox, or tranquilizers. Instead, the medications prescribed are indicated for other disorders, but the effects of taking them can sometimes reduce tremor. There are no specific medications for an essential tremor.
If physical or occupational therapy has not helped, medications can be prescribed. Physical therapists can provide specific muscle exercises that can help with control, coordination and muscle strength.Īn occupational therapist can help you work through your essential tremor in everyday activities with the use of weights and teaching the use of heavier and wider grip tools for specific daily activities. Physical therapy and occupational therapy are one way an essential tremor can be improved.
However, if the essential tremor is getting so that everyday activities are becoming difficult, your doctor might suggest physical or occupational therapy, medications, or surgery depending on the severity of the tremor. Essential tremors can be mild enough that no treatment is necessary.
