Brain implant for addiction approved for four patients in the US

A brain implant for treating addiction is being trialled in the US. The ‘deep brain stimulation’ (DBS) technique is already used in conditions such as epilepsy, obsessive compulsive disorder and Parkinson’s disease, and has been implanted in over 180,000 people worldwide. The procedure involves inserting a 1mm electrode into the area of the brain that regulates self-control. This is the first such trial for addiction and the patients will be closely monitored over the next two years.
