Maybe, the description of the book doesn't exactly get into what the details of the repair processes are - only vaguely referencing that the brain can be repaired.
I've read "Mind Power Into The 21st Century," by John Kehoe (and a couple of his other books.) and while very simple, it offers up several different techniques to reprogram your own brain to be better at whatever it is you desire to be better at. More positive thinking, improving some other skill etc w/ references to various studies done that prove these techniques work & examples of successful people applying them, ie olympic athletes using visualization as a training method as the brain cannot determine the difference between real and imagined and thus closing your eyes and visualizing doing something is just as good as actually doing it in terms of getting better at being able to actually do it. John gets a bit metaphysical, which I like, with his teachings about everything being energy.. and that thoughts are things, and therefor thoughts are also energy that can be manipulated to vibrate on a better frequency and then serve you better, make you happier, attract better things in your life etc etc. I'm sure Eckhart Tolle would agree, as would Einstein and a number of others. Doesn't really matter which source you learn these things from, as they're all essentially the same universal truths.
Reprogramming the brain is basically the key to CBT (Congnitive Behavioural Therapy) as laid out in the book "Feeling Good," by Dr. David Burns. I certainly learned a lot reading this book and applying the techniques. It's been proven to be equally or more so effective at treating depression as antidepressant drugs are, as you use your own thoughts & words and written exercises to essentially re-write and re-wire the programming of your brain in order to change it from depressed to much more optimistic and self serving. Long term practice of any of these things has been proven to get re-wire brains and get them functioning much better.
