It might sound strange, but multiple studies now document the morphologic changes in the brain as a result of chronic pain. The brain gets smaller! The morphological changes involve a decrease in cortical grey matter and white matter volume. Rapid synaptic remodeling also occurs in the somatosensory cortex. Other studies associated with chronic pain patients found decreases in the thalamic size. In a McGill University study of chronic low back pain subjects the brain changes were reversible with treatment. “These data indicate that functional and structural brain abnormalities-specifically in the left DLPFC-are reversible, suggesting that treating chronic pain can restore normal brain function in humans.”
