Chronic pain could be relieved by electrical stimulation of the ventral tegmental area of the brain.
Electrical stimulation to treat chronic pain
Electrical stimulation could be the solution to treat chronic pain, according to the results of a study published in the medical journal Experimental Brain Research. A solution that would reduce the opiate painkillers orders that sometimes cause side effects, including addiction and overdose.
Researchers at the University of Texas at Arlington (United States) were tested in laboratory effectiveness of electrical stimulation on brain structure deep.
They used for the first time a wireless electric device that directly stimulates the ventral tegmental area of the brain. This area involved in positive reinforcement, rewardand addiction, unfolds with such research, as a promising analgesic target. The process also raises beneficial release of dopamine, which helps reduce the stress usuallyassociated with chronic pain.
Limiting the requirements of painkillers
Scientists have observed that this process allows to stop the perception of pain. Indeed, it blocks pain messages in the spinal cord.
"This is therapy part of the chronic pain solution at the forefront of current medicalresearch, it brings hope to in the near future, relieve chronic pain, non-invasively and without the side effects of drugs", the researchers conclude.
A solution for the future, when we know that the opiates cause more overdose thancocaine and heroin combined. Thus, analgesics were involved in over 16,000 deathsin 2010, in the United States only. Concerned, the increase in the number of the prescription of opioid painkillers, the increase in the consumption of painkillers to the long courses such as methadone, the combined use of painkillers with alcohol or other drugs.
