    I was going to post this on an individual thread, however seeing that there have been a lot of posts concerning pain meds. recently, I am making a seperate post.


    Chronic Pain Harms Brain's Wiring

    FRIDAY, Feb. 8 -- Chronic pain can disrupt brain function and cause problems such as disturbed sleep, depression, anxiety and difficulty making simple decisions, a U.S. study finds.

    Researchers at Northwestern University's Feinberg School of Medicine in Chicago used functional MRI to scan brain activity in people with chronic low back pain while they tracked a moving bar on a computer screen. They did the same thing with a control group of people with no pain.

    In those with no pain, the brain regions displayed a state of equilibrium. When one region was active, the other regions calmed down. But in people with chronic pain, the front region of the cortex mostly associated with emotion "never shuts up," study author Dante Chialvo, an associate research professor of physiology, said in a prepared statement.

    This region remains highly active, which wears out neurons and alters their connections to each other. This constant firing of neurons could cause permanent damage.

    "We know when neurons fire too much they may change their connections with other neurons or even die, because they can't sustain high activity for so long," Chialvo said.

    "If you are a chronic pain patient, you have pain 24 hours a day, seven days a week, every minute of your life. That permanent perception of pain in your brain makes these areas in your brain continuously active. This continuous dysfunction in the equilibrium of the brain can change the wiring forever and could hurt the brain," Chialvo explained.

    These changes "may make it harder for you to make a decision or be in a good mood to get up in the morning. It could be that pain produces depression and the other reported abnormalities, because it disturbs the balance of the brain as a whole," he said.

    The study was published in the Feb. 6 issue of The Journal of Neuroscience.

    Chialvo said the findings show that, along with finding new ways to treat pain, it's also important to develop methods to evaluate and prevent disruption of brain function caused by chronic pain.

    this needs to be sent to the site that is taking letters re: the possibility of several pain meds being discontinued....if that made sense - I realize that I just wrote that in sort of a backwards manner, but my brain is not working well enough to make it clearer rt now (there is another thread around here somewhere talking about the pain meds discontinuation issue)

    I am walking or should I say laying down proof of this. My neurophyic (sp) diagonoised me with organic brain sydrome due the being in the state of chronic pain that has not yet been controlled and major deppression caused by the chronic pain. I rated very poor, to poor to below average in my test and I had one of these test in 2003 and it showed some signs but not near this bad. My pain has gotten alot worse as I was in a car accident and I have progressive FMS and at the 10 level with that.
