The fear of falling (FOF) is a natural fear and is typical of most humans and mammals, in varying degrees of extremity.
Other causes include childhood sexual abuse, claustrophobia, agoraphobia, cross phobias (where patients exhibit a number of phobic disorders), panic disorders, anxiety disorders and what I call phobia by association. Phobia by association happens when a patient learns to fear something without any direct experience.
