Ultrasound ‘helmet’ could treat Parkinson’s non-invasively, study shows

Device might replace deep brain stimulation and could also help with Tourette syndrome, Alzheimer’s and depression

An ultrasound “helmet” offers potential new ways for treating neurological conditions without surgery or other invasive procedures, a study has shown.

The device can target brain regions 1,000 times smaller than ultrasound can, and could replace existing approaches such as deep brain stimulation (DBS) in treating Parkinson’s disease. It also holds potential for conditions such as depression, Tourette syndrome, chronic pain, Alzheimer’s and addiction.
