Chronic Pain Damages Brain

Karen Lee Richards Health Guide
  • Scientists at Northwestern University’s Feinberg School of Medicine have discovered a clue that may help explain why chronic pain patients also often suffer with sleep disorders, depression, difficulty making decisions, etc.

    In a healthy brain, the various regions of the brain all exist in a state of equilibrium – when one region is activated, the others become quiet. Researchers found, however, that in chronic pain patients, some areas don’t deactivate when they should. Particularly affected seemed to be a front region of the cortex that is mostly associated with emotion.

    In essence, regions of the brain get stuck on full throttle, constantly firing neurons. Since neurons cannot sustain such high activity for so long, they eventually alter their connections with other neurons or wear out and die, causing permanent damage.

    Needless to say, more research needs to be done to better understand the effects of chronic pain on the brain and to find ways to prevent the damage and dysfunction.
