A hospital in Bristol is believed to be the first in the world to implant a device into a brain to reverse the symptoms of Parkinson’s disease. Southmead Hospital surgeons used a tiny deep brain stimulation (DBS) device to override abnormal brain-cell firing patterns caused by Parkinson’s. Tony Howells, the first person to receive the treatment as part of a trial, said the impact was “amazing”.
The new DBS system, the smallest ever created, involves a tiny battery system for the device implanted into the skull. It then delivers electrical impulses directly to targeted areas of the brain. To do so, electric probes are put through the skull and deep into the centre of the brain, into the subthalamic nuclei. It takes just three hours to carry out the new operation, about half the time it used to with the larger battery.https://www.bbc.com/news/uk-england-bristol-61215241
