THE BRAIN'S WAY OF HEALING

Doidge (Psychiatry/Univ. of Toronto; The Brain that Changes Itself: Stories of Personal Triumph from the Frontiers of Brain Science, 2007) reports on continuing advances in our understanding of the human brain and its unique way of healing.

The author's first book chronicled revolutionary new insights into how the brain can be helped to restructure itself in response to injury. Here, Doidge interviews a second generation of “scientists, doctors and patients,” whom he calls “neuroplasticians.” He recounts his discussion with an American physician specializing in the treatment of chronic pain who pioneered a new method using mental imagery, after he suffered a serious injury. Doidge visited with a controversial 77-year-old sufferer of Parkinson's disease who claims to have been able to reverse his symptoms (and slow the underlying process of deterioration) by focused exercise. One of the most fascinating characters is an Israeli medical practitioner who developed a unique healing method for patients suffering muscular injuries, based on insights from the practice of jujitsu. Doidge uses these and other clinical accounts to illustrate what he claims are three fundamental processes that can be tapped to unleash the brain's healing capacity: the necessity of countering the brain's adaptation to a lost function by “learned nonuse”; the importance of isolating damaged neurons from healthy ones; and the significance of recognizing that “the organic living brain is quite the opposite of an engineered machine with hardwired circuits that can perform only a limited number of actions that it has been designed to do.” Doidge’s takeaway message is that mental activity correlates with neuronal activity, but we still do not know where thought takes place. “This mystery of the mind remains unsolved,” he writes.

A lively, anecdotal account of potential new directions that may point the way to major therapeutic breakthroughs.
