Parkinson’s disease and Essential Tremor can be treated.
Resofus Alomar is pioneering a new kind of treatment, which can destroy the tiny piece of brain tissue causing the tremor without even opening up the skull. The surgery is done using ultrasounds – simple sound waves, but concentrated so much that they can heat up cells until they die. To do this the sound waves are focussed to a single point, just like using a magnifying glass to concentrate light beams on a point they can burn. This concentrated point can be less than a millimeter in diameter, and the surgeons can position it with extreme accuracy using an MRI scanner to guide the beam.
The focussed ultrasound technique is already being used to treat conditions such as uterine fibroids, adenomyosis, facet joints and osteoid osteoma, but getting the ultrasound to pass through the skull is more difficult.
