The answer: Exercise.
Interestingly enough, not all exercise yields the same results.  Aerobic exercise is more effective than stretching and weight lifting. Most studies used walking, as this is the easiest and most acceible exercise for older adults.  It was  found that the cognitive improvement correlated to the distance walked and not to the speed.  So now you know, take a long peaceful walk, improve your mind and enjoy the view.

A very inspiring book.

It was assumed in the past that the brain is like a machine. It was supposed to have specialized centers with fixed locations. It was assumed that only in early infancy, in specific critical periods, the brain is plastic and can change. Therefore, until recently, conventional wisdom held that if   functionality was lost through brain damage the loss was irrevocable.  Most forms of neurological  disorder were considered incurable.

This book’s  premise is that our brain is more plastic then was previously thought. Given the right stimulus,  the brain behaves like a living organism. It  can be trained; it  can change  structure, compensate and adjust for a disability; it can even  recover  functions and develop new functions in adulthood.

Each chapter describes a different method that was used to successfully  overcome a neurological induced disability, from inborn learning disability, to stoke, to traumatic brain injury. This description is done through detailed case histories and interviews. The methods used range anywhere from complex machines to softwares programs and prescribed exercises.

Since neurology and psychiatry are closely intertwined, the book deals with some psychiatric disorders such as as OCD, sexual addiction, and depression.  I believe that the principles outlined in this book can and will be used in the future to treat  more psychiatric disorders.
