A concise, accessible introduction to anxiety covering everything from its causes to its symptoms, available treatment options, and prevention. While anxiety is commonly associated with modern stresses and problems, few realize that disorders of this kind have existed since the beginning of time. What defines "anxiety" as a mental health condition? Who gets it and why? This book looks at this highly treatable condition that is responsible for many lost days of school and work and contributes to rising health care costs. Mental health practitioner Rudy Nydegger addresses the full spectrum of anxiety conditions, examining how they are treated and considering the advantages and disadvantages of each therapy method. From myths and misconceptions to the various scientific theories surrounding anxiety, the author dissects the various disorders stemming from this psychological issue, including obsessive-compulsive behaviors, post-traumatic stress, and phobias; examines the physical responses of our organs to stress—from our skin, to our heart, and to our immune system; and analyzes the epidemiology of those affected. The work concludes with tips for dealing with and preventing anxiety disorders.
