Cambridge trial tests brain implants for addiction treatment

Researchers in the UK are starting a trial for a new treatment aimed at helping people with severe addiction to alcohol and opioids. They will implant electrodes in patients' brains to see if it helps reduce cravings and improve self-control. This method, called deep brain stimulation (DBS), is being tested at Addenbrooke's Hospital in Cambridge and King's College Hospital in London. The study is called the Brain Pacemaker Addiction Control to End Relapse, or Brain-PACER. Scientists hope to help those whose addictions are so severe that traditional treatments do not work. Prof. Valerie Voon from the University of Cambridge said the goal is to see if this technique can change lives for these individuals. DBS involves placing a thin electrode in the brain and a pacemaker device under the skin. These electrodes send electrical signals that can help normalize brain activity. While DBS is commonly used to treat various neurological conditions, this is the first large study focused on its effects on addiction. Experts believe that DBS is safe and can be adjusted as needed, making it a promising option for those struggling with chronic addiction. Dr. David Okai from King's College London said they hope this treatment will improve the quality of life for patients who have not found success with other therapies.
