Like adults, children can experience anxiety disorders; between 10 and 20 percent of all children will develop a full-fledged anxiety disorder prior to the age of 18, making anxiety the most common mental health issue in young people. Anxiety disorders in children are often more challenging to identify than their adult counterparts owing to the difficulty many parents face in discerning them from normal childhood fears. Likewise, anxiety in children is sometimes misdiagnosed as an attention deficit disorder or, due to the tendency of children to interpret their emotions physically (as stomach aches, head aches, etc.), anxiety disorders may initially be confused with physical ailments.
