Although only a small percentage of people suffer from panic disorders, 30 percent to 40 percent of the population will suffer one or more panic attacks in a lifetime. The difference between the occasional attack and suffering from a panic disorder is the frequency and intensity. For people suffering from a panic disorder, the attacks may happen frequently, and the victims tend to "catastrophize" the symptoms.
