Anxiety Disorders: What You Need to Know. Most people experience feelings of anxiety before an important event such as a big exam, business presentation or first date. Anxiety disorders, however, are illnesses that cause people to feel frightened, distressed and uneasy for no apparent reason.
Specific anxiety disorders include generalized anxiety disorder (GAD), panic disorder, separation anxiety disorder, and social anxiety disorder (social phobia). National prevalence data indicate that nearly 40 million people in the United States (18%) experience an anxiety disorder in any given year.
