Who is most likely to be diagnosed with a specific phobia?

Some people do well without treatment because the situation or object they fear is easy to avoid. Bats and caves are examples. If situations or objects (such as thunderstorms) are commonly encountered, treatment is often needed.

Exposure therapy, a type of psychotherapy, is the treatment of choice. Exposure therapy involves exposing people gradually and repeatedly—in their imagination or sometimes in reality—to whatever triggers their fear. People are also taught relaxation and/or breathing techniques to use before and during exposure. Exposure therapy is repeated until people become very comfortable with the anxiety-provoking situation. A therapist can help ensure that the therapy is carried out correctly, although people can do it on their own.

Exposure therapy helps more than 90% of people who do it faithfully. It is almost always the only treatment needed for specific phobias. Even people with a phobia of blood or needles respond well to exposure therapy. For example, such people might begin the exposure by just visiting a doctor's office (or perhaps just walking by the office). The next day (or week), they might sit in an exam room with no intention of getting any blood drawn. The next step might be allowing a needle to be brought close to their skin. Exposure may increase quickly or slowly, but eventually people should allow blood to be drawn.

Drug therapy is not very useful in helping people overcome specific phobias. One exception is the use of benzodiazepines (antianxiety drugs) for some specific phobias. For example, people with flying phobias may use a benzodiazepine prior to boarding the plane. The benzodiazepine alone does not generally eliminate the phobia, but it does allow the person to fly.

The term "phobia" refers to a group of anxiety symptoms brought on by certain objects or situations.

A specific phobia, formerly called a simple phobia, is a lasting and unreasonable fear caused by the presence or thought of a specific object or situation that usually poses little or no actual danger. Exposure to the object or situation brings about an immediate reaction, causing the person to endure intense anxiety (nervousness) or to avoid the object or situation entirely. The distress associated with the phobia and/or the need to avoid the object or situation can significantly interfere with the person's ability to function. Adults with a specific phobia recognize that the fear is excessive or unreasonable, yet are unable to overcome it.

There are different types of specific phobias, based on the object or situation feared, including:

  • Animal phobias: Examples include the fear of dogs, snakes, insects, or mice. Animal phobias are the most common specific phobias.
  • Situational phobias: These involve a fear of specific situations, such as flying, riding in a car or on public transportation, driving, going over bridges or in tunnels, or of being in a closed-in place, like an elevator.
  • Natural environment phobias: Examples include the fear of storms, heights, or water.
  • Blood-injection-injury phobias: These involve a fear of being injured, of seeing blood or of invasive medical procedures, such as blood tests or injections
  • Other phobias: These include a fear of falling down, a fear of loud sounds, and a fear of costumed characters, such as clowns.

A person can have more than one specific phobia.

Symptoms of specific phobias may include:

  • Excessive or irrational fear of a specific object or situation
  • Avoiding the object or situation or enduring it with great distress
  • Physical symptoms of anxiety or a panic attack, such as a pounding heart, nausea or diarrhea, sweating, trembling or shaking, numbness or tingling, problems with breathing (shortness of breath), feeling dizzy or lightheaded, feeling like you are choking
  • Anticipatory anxiety, which involves becoming nervous ahead of time about being in certain situations or coming into contact with the object of your phobia; for example, a person with a fear of dogs may become anxious about going for a walk because they may see a dog along the way.

Children with a specific phobia may express their anxiety by crying, clinging to a parent, or throwing a tantrum.

The National Institute of Mental Health estimates that about 5%-12% of Americans have phobias. Specific phobias affect an estimated 6.3 million adult Americans.

Phobias usually first appear in adolescence and adulthood, but can occur in people of all ages. They are slightly more common in women than in men. Specific phobias in children are common and usually disappear over time. Specific phobias in adults generally start suddenly and are more lasting than childhood phobias. Only about 20% of specific phobias in adults go away on their own (without treatment).

The exact cause of specific phobias is not known, but most appear to be associated with a traumatic experience or a learned reaction. For example, a person who has a frightening or threatening experience with an animal, such as an attack or being bitten, can develop a specific phobia. Witnessing a traumatic event in which others experience harm or extreme fear can also cause a specific phobia, as can receiving information or repeated warnings about potentially dangerous situations or animals.

Fear can be learned from others, as well. A child whose parents react with fear and anxiety to certain objects or situations is likely to also respond to those objects with fear.

If symptoms of a specific phobia are present, the doctor will begin an evaluation by performing a medical and psychiatric history and may perform a brief physical exam. Although there are no lab tests to specifically diagnose specific phobias, the doctor may use various tests to make sure that a physical illness isn't the cause of the symptoms.

If no physical illness is found, you may be referred to a psychiatrist, psychologist, or other mental health professional who is specially trained to diagnose and treat mental illnesses. Psychiatrists and psychologists use clinical interviews and assessment tools to evaluate a person for a specific phobia.

The doctor bases their diagnosis of specific phobias on reported symptoms, including any problems with functioning caused by the symptoms. A specific phobia is diagnosed if the person's fear and anxiety are particularly distressing or if they interfere with their daily routine, including school, work, social activities, and relationships.

Treatment for specific phobias may include one or a combination of:

  • Cognitive behavioral therapy: Psychotherapy is the cornerstone of treatment for specific phobias. Treatment usually involves a type of cognitive behavioral therapy, called systematic desensitization or exposure and response prevention (ERP) therapy, in which patients are gradually exposed to what frightens them until their fear begins to fade.
  • Medication: For situational phobias that produce intense, temporary anxiety (for example, a fear of flying), short-acting sedative-hypnotics (benzodiazepines) such as alprazolam (Xanax) or lorazepam (Ativan) may be prescribed on an occasional, as-needed basis to help reduce anticipatory anxiety. Unless a phobia is accompanied by other conditions such as depression or panic disorder, long-term or daily medicines are generally not used. Occasionally, serotonergic antidepressants such as escitalopram oxalate (Lexapro),  fluoxetine (Prozac), and  paroxetine (Paxil) may have potential value for some patients. More recently, common blood pressure drugs called beta-blockers have been used to treat anxiety related to specific phobias.
  • Relaxation techniques, such as deep breathing, may also help reduce anxiety symptoms.

For most people, specific phobias can be successfully treated with therapy, medication, or a combination of both.

Although many specific phobias cannot be prevented, early intervention and treatment following a traumatic experience, such as an animal attack, may prevent the person from developing a severe anxiety disorder.

A phobia is an uncontrollable, irrational, and lasting fear of a certain object, situation, or activity. This fear can be so overwhelming that a person may go to great lengths to avoid the source of this fear. One response can be a panic attack. This is a sudden, intense fear that lasts for several minutes. It happens when there is no real danger.

Who is affected by phobias?

About 19 million Americans have one or more phobias that range from mild to severe. Phobias can happen in early childhood. But they are often first seen between ages 15 and 20. They affect both men and women equally. But men are more likely to seek treatment for phobias.

What causes phobias?

Research suggests that both genetic and environmental factors contribute to the start of phobias. Certain phobias have been linked to a very bad first encounter with the feared object or situation. Mental health experts don’t know if this first encounter is necessary or if phobias can simply occur in people who are likely to have them.

What are the main types of phobias?

Specific phobia

What is specific phobia?

Specific phobia is an extreme fear of an object or situation that typically isn't harmful.

Examples may include a fear of:

  • Flying (fearing the plane will crash)
  • Dogs (fearing the dog will bite or attack)
  • Closed-in places (fear of being trapped)
  • Tunnels (fearing a collapse)
  • Heights (fear of falling)

What are the characteristics of specific phobia?

People with specific phobia know that their fear is extreme. But they can't overcome it. The problem is diagnosed only when the specific fear interferes with daily activities of school, work, or home life.

There is no known cause, although they seem to run in families. They are also found slightly more often in women. If the object of the fear is easy to avoid, people with phobias may not seek treatment. Sometimes, however, they may make important career or personal decisions to avoid a situation that includes the source of the phobia.

Treatment for specific phobia

When phobias interfere with a person's life, treatment can help. For specific phobias, cognitive-behavioral therapy (CBT) with exposure treatment is advised. In exposure therapy, people are gradually exposed to what frightens them until the fear starts to fade. Relaxation and breathing exercises also help to ease symptoms.

Social phobia

What is social phobia?

Social phobia is an anxiety disorder in which a person has significant anxiety and discomfort related to a fear of being embarrassed, humiliated, or scorned by others in social or performance situations. Even when they manage to confront this fear, people with social phobia usually:

  • Feel very anxious before the event or outing
  • Feel intensely uncomfortable throughout the event or outing
  • Have lingering unpleasant feelings after the event or outing

Social phobia often happens with the following:

  • Public speaking
  • Meeting people
  • Dealing with authority figures
  • Eating in public
  • Using public restrooms

What are the characteristics of social phobia?

Although this disorder is often thought of as shyness, they are not the same. Shy people can be very uneasy around others, but they don't have the extreme anxiety in anticipating a social situation. Also, they don't necessarily avoid circumstances that make them feel self-conscious. In contrast, people with social phobia are not necessarily shy at all, but can be completely at ease with some people most of the time.

Most people with social phobia will try to avoid situations that cause distress.

Diagnosing social phobia

Social phobia is diagnosed when the fear or avoidance significantly interferes with normal, routines, or is excessively upsetting.

Social phobia disrupts normal life, interfering with career or social relationships. It often runs in families and may be happen along with depression or alcoholism. Social phobia often starts in early adolescence or even younger. 

Treatment for social phobia

People with social phobia often find relief when treated with cognitive-behavioral therapy, medicine, or a mix of both.

Agoraphobia

What is agoraphobia?

Agoraphobia involves the fear of having a panic attack in a place or situation from which escape may be hard or embarrassing.

The anxiety of agoraphobia is so severe that panic attacks are not unusual. People with agoraphobia often try to avoid the location or cause of their fear. Agoraphobia involves fear of situations like the following:

  • Being alone outside his or her home
  • Being at home alone
  • Being in a crowd
  • Traveling in a vehicle
  • Being in an elevator or on a bridge

People with agoraphobia typically avoid crowded places like streets, crowded stores, churches, and theaters.

What are the characteristics of agoraphobia?

Most people with agoraphobia get it after first suffering a series of panic attacks. The attacks happen randomly and without warning, and make it impossible for a person to predict what will trigger the reaction. This unpredictability of the panic causes the person to anticipate future panic attacks and, eventually, fear any situation in which an attack may happen. As a result, they avoid going into any place or situation where previous panic attacks have happened.

People with the disorder often become so disabled that they literally feel they cannot leave their homes. Others who have agoraphobia, do go into potentially "phobic" situations, but only with great distress, or when accompanied by a trusted friend or family member.

People with agoraphobia may also have depression, fatigue, tension, alcohol or drug abuse problems, and obsessive disorders, making treatment crucial.
