Panic disorder, as a condition, most often begins in late adolescence and early adulthood. According to the National Institute of Mental Health (NIMH), the condition affects close to 2.4 million adult Americans, which translates to 1.1 percent of the entire population.
Panic disorder strikes without reason or warning, and the affected person expresses disproportionate fear response for non-threatening situations. The rate of this disorder in women is twice as in men.
The reason why victims need help for panic disorder is because over time, these people develop a constant and spiraling fear of going through another attack. This can potentially affect their quality of life and daily functioning.
