Phobias

A phobia is a type of anxiety disorder, defined by a persistent and excessive fear of an object or situation. The phobia typically results in a rapid onset of fear and is present for more than six months. The affected person goes to great lengths to avoid the situation or object, to a degree greater than the actual danger posed. If the feared object or situation cannot be avoided, the affected person experiences significant distress. With blood or injury phobia, fainting may occur. Agoraphobia is often associated with panic attacks. Usually a person has phobias to a number of objects or situations.

Agoraphobia is often associated with panic attacks. Usually a person has phobias to a number of objects or situations. Phobias can be divided into specific phobias, social phobia, and agoraphobia. Types of specific phobias include those to certain animals, natural environment situations, blood or injury, and specific situations. The most common are fear of spiders, fear of snakes, and fear of heights. Occasionally they are triggered by a negative experience with the object or situation. Social phobia is when the situation is feared as the person is worried about others judging them. Agoraphobia is when fear of a situation occurs because it is felt that escape would not be possible. It is recommended that specific phobias be treated with exposure therapy where the person is introduced to the situation or object in question until the fear resolves. Medications are not useful in this type of phobia. Social phobia and agoraphobia are often treated with some combination of counselling and medication. Medications used include antidepressants, benzodiazepines, or beta-blockers. Specific phobias affect about 6–8% of people in the Western world and 2–4% of people in Asia, Africa, and Latin America in a given year. Social phobia affects about 7% of people in the United States and 0.5–2.5% of people in the rest of the world. Agoraphobia affects about 1.7% of people. Women are affected about twice as often as men. Typically onset is around the age of 10 to 17. Rates become lower as people get older. People with phobias are at a higher risk of suicide. Most phobias are classified into three categories and, according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-V), such phobias are considered sub-types of anxiety disorder. The categories are: 1. Specific phobias: Fear of particular objects or social situations that immediately results in anxiety and can sometimes lead to panic attacks. Specific phobia may be further subdivided into four categories: animal type, natural environment type, situational type, blood-injection-injury type. 2. Agoraphobia: a generalized fear of leaving home or a small familiar 'safe' area, and of possible panic attacks that might follow. It may also be caused by various specific phobias such as fear of open spaces, social embarrassment (social agoraphobia), fear of contamination (fear of germs, possibly complicated by obsessive-compulsive disorder) or PTSD (post traumatic stress disorder) related to a trauma that occurred out of doors. 3. Social phobia, also known as social anxiety disorder, is when the situation is feared as the person is worried about others judging them. Phobias vary in severity among individuals. Some individuals can simply avoid the subject of their fear and suffer relatively mild anxiety over that fear. Others suffer full-fledged panic attacks with all the associated disabling symptoms. Most individuals understand that they are suffering from an irrational fear, but are powerless to override their panic reaction. These individuals often report dizziness, loss of bladder or bowel control, tachypnea, feelings of pain, and shortness of breath.
