But you may experience anxiety that is persistent, seemingly uncontrollable, and overwhelming. If it’s an excessive, irrational dread of everyday situations, it can be disabling. When anxiety interferes with daily activities, you may have an anxiety disorder.
The term "anxiety disorder" refers to generalized anxiety disorder (GAD) , obsessive-compulsive disorder (OCD) , panic disorder , posttraumatic stress disorder (PTSD) , social anxiety disorder (also called social phobia) , and specific phobias .
Anxiety disorders are the most common psychiatric illnesses affecting children and adults. An estimated 40 million American adults suffer from anxiety disorders. Only about one-third of those suffering from an anxiety disorder receive treatment , even though the disorders are highly treatable.
