Excess Weight Is Not The Verdict – Part 1 of 3
Excess Weight Is Not The Verdict. For the foremost time, researchers have shown that implanting electrodes in the brain’s “feeding center” can be safely done – in a bid to happen a new treatment option for severely obese people who fail to shed pounds even after weight-loss surgery. In a preliminary study with three patients, researchers in June 2013 found that they could safely use the therapy, known as chasmic brain stimulation (DBS). Over almost three years, none of the patients had any serious side effects, and two even lost some weight – but it was temporary. “The essential thing we needed to do was to see if this is safe,” said lead researcher Dr Donald Whiting, vice chairman of neurosurgery at Allegheny General Hospital in Pittsburgh.
And “We’re at the point now where it looks be partial to it is”. The study, reported in the Journal of Neurosurgery and at a meeting this week of the International Neuromodulation Society in Berlin, Germany, was not meant to test effectiveness. So the big remaining call in is, can deep brain stimulation actually promote lasting weight loss?
“Nobody should get the idea that this has been shown to be effective. This is not something you can go ask your doctor about”. Right now, deep capacity stimulation is sometimes used for tough-to-treat cases of Parkinson’s disease, a movement disorder that causes tremors, stiff muscles, and balance and coordination problems. A surgeon implants electrodes into explicit movement-related areas of the brain, then attaches those electrodes to a neurostimulator placed under the skin near the collarbone.
The neurostimulator continually sends tiny electrical pulses to the brain, which in turn interferes with the eccentric activity that causes tremors and other symptoms. What does that have to do with obesity? In theory deep brain stimulation might be able to “override” brain signaling involved in eating, metabolism or feelings of fullness.
