Chronic pain could disturb the balance of the brain and
lead to other health problems, a new study says.
A chronic pain patient suffers from pain 24 hours a day, seven days a week,
every minute of the life, the study said.
This could trigger other health problems like disturbed sleep, depression,
anxiety and difficulty in making simple decisions.
That
permanent perception of pain makes a particular area of the brain
continuously active. This continuous dysfunction could hurt the brain,
said the study that appeared in the Feb 6 issue of The Journal of
Neuroscience.
Researchers led by Dante Chialvo used functional
magnetic resonance imaging 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 where one region was active, the other regions calmed down,
reported health portal Health Day.
But in people with chronic
pain, the front region of the brain associated with emotion "never
shuts up", Chialvo at Northwestern University's Feinberg School of
Medicine in Chicago said. This region remains highly active that could
cause permanent damage.
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.
