In-brain electrodes are the latest weapon against opioid addiction
Researchers at the West Virginia University Rockefeller Neuroscience Institute (RNI) and West Virginia University Medicine are conducting the first clinical trial in the US that uses deep brain stimulation to treat opioid addiction. The procedure is meant for those who have exhausted all other forms of treatment but still suffer from opioid use disorder. The first patient, a 33-year-old man, has a decade-long history of opioid and benzo abuse, overdoses and relapses.
How electrifying the brain wards off Parkinson's disease
Implanting electrodes in the brain and zapping it helps patients with Parkinson's and other disorders, but doctors have never been sure why, exactly. Now, researchers from UC San Francisco think that the therapy (called deep-brain stimulation, or DBS) works by altering neural timings, in much the same way a defibrillator resets heart rhythms. In a healthy brain, neuron firing is controlled by low frequency rhythms that sync up movement, memory and other functions. But the UC team found that the synchronization is too strong in Parkinson's patients, making it harder for them to move voluntarily.
Brain pacemakers show promise in Alzheimer's trials, might open new treatment possibilities
Deep-brain electrical stimulation has been around for a while -- rousing folks from comas and helping researchers find new ways to treat OCD, depression and maybe even obesity. Now doctors are testing the so-called "brain pacemakers," on Alzheimer's patients and the results are promising, but not conclusive. After a year of treatment, six patients showed higher glucose consumption in PET scans of the learning and memory areas of the brain -- a change that is associated with increased neuron activity. Glucose metabolism typically decrease as a result of the disease. Researchers are seeking more patients for the trial, and are optimistic that the technique could one day be used to stave off some of Alzheimer's debilitating symptoms.
European Parkinson's patients receive first Libra DBS implants to help alleviate symptoms
St. Jude Medical's announced that patients from Austria, Germany, and Greece are among the first to be implanted with Libra Deep Brain Stimulation (DBS) devices to alleviate the symptoms of advanced Parkinson's Disease. Specifically, it's able to reduce akinesia, rigidity, tremor, and motor complications associated with taking levodopa.The company's touting Libra and LibraXP as having the longest-lasting battery of any DBS in their class, meaning potentially less surgical procedures needed for for when they gotta be replaced. No word on when they'll be expanding use of the device, but we're sure it's coming.[Via Medgadget]
Deep-brain electrical stimulation brings man out of vegetative state
A 38-year-old man who had been in a near-coma for six years was recently awakened via the use of a pacemaker and two electrodes which were deeply implanted in his brain. The electrical device, manufactured by a company called Medtronic, was used to send impulses to the area of the brain regulating consciousness, and researchers believe that the stimulation may be enhancing brain circuits that are still capable of functioning. The man, the first of 12 to undergo the procedure, has gone from a vegetative state to being able to play cards, speak with family members, and take trips outside. While this isn't exactly a new technology -- as doctors have been experimenting with deep-brain stimulation in the treatment of Parkinson's, epilepsy, and brain injuries for some time -- it is a clear sign that there's hope for patients whom the medical community has been, heretofore, unable to treat.
