Summary: Chronic Pain Harms The Brain
ScienceDaily (Feb. 6, 2008) -- People with
unrelenting pain don't only suffer from the non-stop
sensation of throbbing pain. They also have trouble
sleeping, are often depressed, anxious and even have
difficulty making simple decisions.
In a new study, investigators at Northwestern
University's Feinberg School of Medicine have
identified a clue that may explain how suffering long-
term pain could trigger these other pain-related
Researchers found that in a healthy brain all the
regions exist in a state of equilibrium. When one
region is active, the others quiet down. But in people
with chronic pain, a front region of the cortex mostly
associated with emotion "never shuts up," said Dante
Chialvo, lead author and associate research professor
of physiology at the Feinberg School. "The areas that
are affected fail to deactivate when they should."
They are stuck on full throttle, wearing out neurons
