The idea of a disorder called bipolar is largely based on people having faulty brains.
Brain scans of people starting to display extremes of mood hardly ever show faulty brains. They in fact seem to be reacting to what has happened to them.
When traumatized, drinking a lot of alcohol or taking street drugs brain chemistry changes. This change is temporary. Some people take a lot longer than others to naturally get over disturbing experiences. When given good support, good nutrition and reassurance that their reactions are what has always happened to people under pressure, then their brain chemistry gradually returns to be much the same as anyone else.
Text books about the brain tend to be too complex and go out of date. I have attended talks by experts and, even as a qualified chemist, struggled to keep up. What is needed is to have the facts interpreted and explained by a lay person with an extraordinary enthusiasm for sharing knowledge that up to now has only been available to a few doctors and pharmaceutical businesses.
Attending a talk by Robert Whitaker I met Catherine Clark who is one of those people with the energy and enthusiasm to share in a way we can all understand… See Catherine Clark’s > Story of the Brain
