Anxiety disorders, such as post-traumatic stress disorder or panic attacks, are illnesses that fill people's lives with overwhelming worry and fear. Regardless of the type, the anxiety that a person feels is generally chronic, unremitting, and can grow progressively worse. Some people are so tormented by panic attacks, obsessive thoughts, flashbacks of traumatic events, and other symptoms of their anxiety disorders that they can even become housebound. Several conditions are related to extreme anxiety; fortunately, treatments for the condition can be effective at any age. If you think you may have an anxiety disorder, don't hesitate to discuss it with your healthcare provider.
