The treatment of neurologic disease took a major step forward this past week with the publication of a clinical trial that used ultrasound waves to treat Essential Tremor. Essential tremor affects about 10 million people in the USA and can be extremely disabling. For patients that fail medical therapy invasive surgical options are considered, including deep brain stimulation (DBS). DBS surgeries involve drilling a hole in the skull and implanting an electrode into structures deep in the brain to turn off the unwanted signals that cause the tremor.
A study of 15 patients lead by Dr. Jeff Elias (University of Virginia) was published in the New England Journal of Medicine this week and describes how researchers used ultrasound waves to effectively treat Essential tremor non-invasively – no cutting or drilling:
