Phobias arise from a combination of external and internal predispositions.
Heredity, genetics, and brain chemistry combined with life-experiences play a major role in the development of anxiety disorders like panic disorders and phobia.
Amygdala secretes hormones that control fear and aggression
When the fear or aggression response is initiated, amygdala releases hormones releases hormones in the body, to create an alert state as flight and fight responses.
Animal phobias- fear of snakes, spiders, rodents, and dogs.
Natural environment phobias- fear of heights, storms, water, and dark.
Situational phobia- fear of enclosed spaces (claustrophobia), fear of elevators, flying, driving, tunnels or bridges
Blood- injection-injury phobia
Earlier agoraphobia was thought to involve a fear of public places and open spaces, now it’s believed that agoraphobia develops as a complication of panic attacks or panic disorder.
People with agoraphobia become anxious and develop fear during the situations, where escape would be difficult or embarrassing, or even help would not be immediately available.
