Mind Over Matter: The Brain’s Way of Healing

The Brain's Way of HealingIn 2008 I wrote about neuroplasticity as presented in Norman Doidge’s book The Brain That Changes Itself. I urge you to click on the link and read what I wrote there before you continue. The science is fascinating. The brain is far more malleable than we once thought. Areas of the cortex devoted to a sensory input shrink when that input is lost. Neurons from other parts of the brain can be co-opted to take over lost functions. Learning a new skill actually changes the structure and function of the brain: the areas of the cortex devoted to that skill enlarge as the new skill is practiced and perfected.

This is exciting stuff, with potential therapeutic applications in chronic pain, brain damage, and chronic illness. When I reviewed that book, I said I thought Doidge was a bit overenthusiastic; and now he has written a follow-up book that is even more overenthusiastic. In The Brain’s Way of Healing: Stories of Remarkable Recoveries from the Frontiers of Neuroplasticity, he slips into unscientific speculations and relies on anecdotes about patients who have allegedly benefited from practical applications of brain plasticity science. The title is accurate: these are stories, not scientific studies. I continue to find the subject fascinating and to believe that neuroplasticity offers a lot of potential for human healing, but I don’t believe we have learned much about practical ways to accomplish that. Doidge’s book goes beyond the science. (more…)

Chronic Pain: A Disease in its Own Right

Melanie Thernstrom has written a superb book based on a historical, philosophical, and scientific review of pain: The Pain Chronicles: Cures, Myths, Mysteries, Prayers, Diaries, Brain Scans, Healing, and the Science of Suffering. Herself a victim of chronic pain, she brings a personal perspective to the subject and also includes informative vignettes of doctors and patients she encountered at the many pain clinics she visited in her investigations. She shows that medical treatment of pain is suboptimal because most doctors have not yet incorporated recent scientific discoveries into their thinking, discoveries indicating that chronic pain is a disease in its own right, a state of pathological pain sensitivity.

Chronic pain often outlives its original causes, worsens over time, and takes on a puzzling life of its own… there is increasing evidence that over time, untreated pain eventually rewrites the central nervous system, causing pathological changes to the brain and spinal cord, and that these in turn cause greater pain. Even more disturbingly, recent evidence suggests that prolonged pain actually damages parts of the brain, including those involved in cognition. (more…)
