The first hurdle to surmount is the writing. Robbins is a magazine journalist, and the book reads like every other pop psych book written by a magazine journalist. It's heavy on the personal stories and light on science. Way too much of the material is from interviews. There's about 50 pages of filler, mostly history. And, in the tradition of books about medical breakthroughs, it's packed with case histories of success.
More seriously, Robbins doesn't reveal a fact I know from other sources: he was commissioned by one of the players in the story. More about this below.
The history of neurofeedback begins with a UCLA researcher named Barry Sterman and his graduate student, Margaret Ayers. They developed a method for using biofeedback with EEG to help patients control their own brain waves. The technique showed promise and Ayers left to take it into clinical practice, causing the first of many wars in this field. She took with her the technician who had built the original machine, and started a company called Neuropathways. She did therapy and also sold hardware and software.
As usual there was a lot of resistance from medical and psychological experts to this new treatment. There weren't any good large-scale studies of its efficacy, so clinicians wouldn't touch it, and no grant money could be scared up to do such studies. Marginalized as she was, Ayers took on the defensive, messianic role of the radical truth-bringer oppressed by closed-minded conservatives. Robbins tells this story pretty well. You can see that there was merit in the therapy and that new ideas were treated unfairly, and you can also see that everyone involved was prickly enough to make things worse. However, Ayers had a lot of success helping patients who were in coma states, where no other treatment even seemed possible, and began to take clients with severely unhappy children who were violent or otherwise uncontrollable and had failed attempts at other help.
The narrative then moves on to a couple named Siegfried and Sue Othmer, and stays with them for the rest of the book. They brought their son to Ayers after the usual series of failures in other treatments for his severe neurological and psychiatric problems. The neurofeedback worked so well that they became enthusiastic converts to this new idea. In fact, they became so enamored of it that they bought equipment and trained themselves in its use. They and Ayers and Ayers' computer programmer planned a joint venture to spread the good news and get more trained practitioners and equipment distributed.
This relationship also broke down in a mess of broken verbal agreements, patents, lawsuits, and accusations of bad faith. The Othmers started their own venture, EEG Spectrum, and began training and selling equipment themselves.
The rest of the book is taken up with examples of neurofeedback's uses in epilepsy, ADD, injury, drug dependence, and personality disorders. Some of the case histories are fascinating. Unfortunately the practitioners and clients have a breathless enthusiasm for neurofeedback that breeds skepticism. In a chapter on ADD treatment, for example, Robbins and his interview subjects come perilously close to saying that drug therapy for psychiatric problems is the same thing as drug abuse, and that the "medical establishment" are drug dealers who don't want to lose their hapless victim-patients. There is about a 20 page attack on the idea of treating ADD patients with drugs, and many of the arguments are essentially religious. This is unnecessary and brings down the tone of the whole narrative, and should have been eliminated.
This points to the real problem with the book, which is that Robbins has given us a pop psych cheerleading exercise about the wonders of neurofeedback that lacks critical bite. He does take trouble to interview some opponents of the technique but they're straw men he sets up to knock down. And as above with the drug rant, there are a number of places where the tired old idea that "they" don't want you to know about the real thing that will cure you pops up. There's a bestselling book with a title like "The natural cures they won't tell you about" that plays on this unreasonable idea that physicians and psychologists want their patients to be sick and take expensive drugs and treatments. It's very unhelpful and also untrue, as you'll find out if you spend a little time around "them".
The problem with new treatments like this, and with their proponents like Ayers and the Othmers, is that they're crusaders and not scientists. At a certain point in her career Ayers walked away from research because she saw so much potential for immediate clinical use. Her patients benefited but medical science did not. And the Othmers are neither clinical professionals nor scientists; they're boosters. The fact that both of these parties make their living selling training and equipment for neurofeedback does not help things at all. Psychological therapies in the world of "alternative medicine" turn into cults too easily, and more so when charismatic leaders with a lot at stake take charge of them.
The really damning thing about A Symphony in the Brain is that it was commissioned by the Othmers and Robbins doesn't reveal this. I only know it because people closer to the story than I revealed it. He makes a pretense of having stumbled upon this and decided on his own to write the book, so I'm not sure how exactly it happened. In any case he's far too closely tied to them and their story. He does give Ayers a fair shake rather than taking their side, which is a good sign.
After finishing this book I thought about my own practitioner and the nature of this treatment. Like the Othmers and Ayers and Robbins, she's a true believer. Neurofeedback approaches the Solution to Everything, kook-style, for true believers. Considering the history of "cures" for ADD and personality disorders over the years (sugar-free diets, weird psychotherapies, cult-like schooling) I can't help feeling very skeptical. In my own case I have nothing to lose but $95 a session unless it turns me into a werewolf or a catatonic, so I'm going ahead with it. I really wish someone would do a proper study with a large patient population on neurofeedback, though. The war between conservatives and radicals is harmful to patients.
