An estimated 45 million Americans experience chronic headaches. For at least half of these people, the problem is severe and sometimes disabling. Some suffering can be alleviated. Stress and depression are important headache triggers that can be diagnosed and treated adequately. Other headache pain is poorly understood and traditional treatment methods can be inadequate. This Sourcebook contains information about the most common types of headaches, their different causes, and tips for headache prevention. It provides helpful information about headache treatment, including facts about medications and the role of alternative medicine in alleviating headache pain. Individual chapters also focus on the special concerns of women and children with headaches. In addition, this book offers a glossary of headache-related terms and a list of resources for further help and information.
