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

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.

Unlike DBS, which requires a highly invasive procedure in which electrodes are implanted deep in the brain to deliver electrical pulses, using ultrasound sends mechanical pulses into the brain.

But no one had managed to create an approach capable of delivering them precisely enough to make a meaningful impact until now.

A study published in Nature Communications introduces a breakthrough system that can hit brain regions 30 times smaller than previous deep-brain ultrasound devices could.

This could be a gamechanger

1. Awesome. But will our anti-science government embrace it or ban it?

I was reading that red light therapy (NIR) was also therapeutic. They sell caps on Alibaba at 850 and 960 nm. According to this study-"808 nm light exhibited the deepest penetration into the brain, reaching depths of 40–50 mm" This was done on cadaver brains. Other parts point to higher wavelengths.
