Anxiety, however, is excessive or inappropriate arousal characterized by feelings of apprehension, uncertainty, and fear. The word is derived from the Latin, angere , which means to choke or strangle. It is often not attributable to a real or appropriate threat and can paralyze the individual into inaction or withdrawal. Anxiety can also be a symptom of other psychologic or medical problems, such as depression, substance abuse, or thyroid disease.
Anxiety disorders are the most common psychiatric condition in the United States.
Nevertheless, only about a quarter of those who experience this problem seek help. Anxiety disorders are usually caused by a combination of psychological, physical, and genetic conditions, and treatment is, in general, very effective. All rights reserved.
