According to recent studies, women are more than twice as likely as men to develop posttraumatic stress disorder. Lifetime prevalence in the United States is about 7 percent, but in high-risk groups, such as combat veterans and victims of violent crimes like rape or assault, it may be as high as 25–30 percent.
Diagnosis of posttraumatic stress disorder is based on the clinical history of the patient and the occurrence of a traumatic event.
This disorder is characterized by frequent, recurring panic attacks - sudden, unexpected feelings of intense fear and discomfort.
Anxiety levels sometimes spin out of control, causing psychological and physical symptoms that interfere with normal function.
