MR-guided focused ultrasound is a new technique that involves focusing 1024 beams of ultrasound through the skull to a focal point in the brain, very much like using the sun and a magnifying glass to burn a hole in a sheet of paper.
Access to neurological care for Parkinson disease is currently limited by distance, disability, and the distribution of doctors.
The prevalence of obesity is about 20 % in Australia, 17 % in Japan, but only 3 – 4 % in China. Thus, Asia Pacific is a very heterogeneous region.
