Jeff''s family and friends described him as "good-looking," "fun-loving," "quick-witted," and "talented." He was kind, friendly, ambitious and always succeeded at every task he undertook. No one was surprised when Jeff was selected to represent his school in an international exchange program. But when Jeff returned to Ridgemont High a year later, everyone was shocked at his change in behavior. Why was Jeff so angry and out of control? Could it have something to do with his health? Many medical conditions have serious psychological components and effects. Sometimes, a medical condition in the body can lead to medical disorders of the mind. These are called mental disorders due to a medical condition. Adolescents are among those who suffer from medical conditions, and they are not immune to the accompanying psychological issues that may be involved. But mental disorders caused by medical conditions bring additional challenges to adolescents. Everyday care, management, regulating medication, and the emotional ramifications of medical conditions can be difficult for anyone. Attempting to balance these challenges while maintaining schoolwork, jobs, and extra-curricular activities can add to the stress for young people. In this book, you will learn about some medical disorders, the psychological complications that can result, and the treatments available to fight them. Along the way, you will explore the advances in drug treatment for psychological disorders, how such drugs work, and the risks and side effects associated with these treatments. Numerous case studies and stories of young people like Jeff who are coping with mental disorders caused by medical conditions illustrate the realities of these illnesses, while a chapter on alternative treatment adds information about additional treatment options.
