Hi @afirefly Is this book relatively new with up to date information? I believe in neuroplasticity. It engages the brain to develop new pathways for tasks it once did. In other words, you teach your brain to do a task using a different pathway of nerves it used before. Pretty interesting concept. I must say it involves discipline, time, and patience. In some cases it took as long as a year to achieve change. I am using neuroplasticity to correct my diplopia caused by the nerves of my eye muscles. The movements of the eyes do not synchronize with each other thus resulting in 2 images, the diplopia. At 3 months I have seen positive changes but my eyes have not completely aligned yet. I also have neuropathy and balance issues. I have noticed yesterday after a month, the exercises for balance are becoming easier. I will advance to another exercise for balance improvement. Thanks, Toni
