  • Panic disorder typically develops in early adulthood (median age of onset is 24), but the age of onset extends throughout adulthood.
  • About one in three people with panic disorder develops agoraphobia, a condition in which the individual becomes afraid of being in any place or situation where escape might be difficult or help unavailable in the event of a panic attack.

Obsessive-Compulsive Disorder (OCD)

  • Approximately 2.2 million American adults age 18 and older, or about 1.0 percent of people in this age group in a given year, have OCD.
