Diagnostic tests are unable to find the cause of symptoms in at least half of all medical patients, most of whom are ill because of hidden stresses. Dr. David Clarke has done pioneering work with over 7,000 of these patients, often sent to him as a last resort.  In plain language he describes the major types of stress and explains steps for treatment with a range of effective techniques. Case histories that read like medical mysteries illustrate the concepts and make them easy to apply. This significant book offers real solutions to put a stop to the stress illness epidemic.
