This disorder may eventually lead to phobias that cause people to completely avoid certain situations.
Panic disorder — a type of anxiety disorder — is a serious condition characterized by a sudden, unexpected fear that something bad will happen, even when there’s no apparent danger.
For people with panic disorder, these "panic attacks" are recurrent and can happen at any time, often causing them to live with constant worry or dread that more attacks will occur.
