Phobias
A phobia is a type of anxiety disorder, which is usually defined by an intense fear of something that, in reality, poses little or no actual danger. It is normal and even helpful to experience fear in dangerous situations, but with phobias the threat is greatly exaggerated or nonexistent.
Common phobias and fears include closed-in places, heights, highway driving, flying insects, snakes, and needles
If you have a phobia, you probably realize that your fear is unreasonable, yet you still can’t control your feelings.
Understanding your phobia is the first step to overcoming it. It’s important to know that phobias are common. It also helps to know that phobias are highly treatable. You can overcome your anxiety and fear, no matter how out of control it feels.

About Phobias
A phobia is a type of anxiety disorder, which is usually defined by an intense fear of something that, in reality, poses little or no actual danger. It is normal and even helpful to experience fear in dangerous situations. Fear is an adaptive human response. It serves a protective purpose, but with phobias the threat is greatly exaggerated or nonexistent.
For example, it is only natural to be afraid of a snarling Doberman, but it is irrational to be terrified of a friendly poodle on a leash, as you might be if you have a dog phobia.
Common phobias and fears include closed-in places, heights, highway driving, flying insects, snakes, and needles. However, we can develop phobias of virtually anything. Most phobias develop in childhood, but they can also develop in adults. Phobias are categorized into Specific Phobias and Social Phobias.
– Specific phobias are phobias to specific objects or environments, such as arachnophobia (spider phobia) or acrophobia (phobia of heights)
– Social phobias are phobias within social situations, such as public speaking and crowded areas. Some phobias, such as xenophobia, overlap with many other phobias.
If you have a phobia, you probably realize that your fear is unreasonable, yet you still can’t control your feelings. Just thinking about the feared object or situation may make you anxious. When you’re actually exposed to the thing you fear, the terror is automatic and overwhelming. The experience is so nerve-wracking that you may go to great lengths to avoid it—inconveniencing yourself or even changing your lifestyle.
Understanding your phobia is the first step to overcoming it. It’s important to know that phobias are common. (Having a phobia doesn’t mean you’re crazy!) It also helps to know that phobias are highly treatable. You can overcome your anxiety and fear, no matter how out of control it feels.

Most childhood fears are natural and tend to develop at specific ages. For example, many young children are afraid of the dark and may need a nightlight to sleep. That doesn’t mean they have a phobia. In most cases, they will grow out of this fear as they get older.
If your child’s fear is not interfering with his or her daily life or causing him or her a great deal of distress, then there’s little cause for undue concern. However, if the fear is interfering with your child’s social activities, school performance, or sleep, you may want to see a qualified child therapist.
According to the Child Anxiety Network, the following fears are normal:
– 0-2 years – Loud noises, strangers, separation from parents, large objects.
– 3-6 years – Imaginary things: monsters, the dark, sleeping alone, strange noises.
– 7-16 years – More realistic fears: injury, school performance, death
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. Most phobias are classified into two categories and, according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-V), such phobias are considered to be sub-types of anxiety disorder.
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 five categories: animal type, natural environment type, situational type, blood-injection-injury type, and other
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.
There are four general types of phobias and fears:
The symptoms of a phobia can range from mild feelings of apprehension and anxiety to a full-blown panic attack. Typically, the closer you are to the thing you’re afraid of, the greater your fear will be. Your fear will also be higher if getting away is difficult.
Specific phobias are defined in relation to objects or situations whereas social phobias emphasize social fear and the evaluations that might accompany them.
Specific Phobias
A specific phobia is a marked and persistent fear of an object or situation which brings about an excessive or unreasonable fear when in the presence of, or anticipating, a specific object; the specific phobias may also include concerns with losing control, panicking, and fainting which is the direct result of an encounter with the phobia.
The DSM breaks specific phobias into five subtypes: animal, natural environment, blood-injection-injury, situational, and other.
In children, phobias involving animals, natural environment (darkness), and blood-injection-injury usually develop between the ages of 7 and 9, and these are reflective of normal development. Additionally, specific phobias are most prevalent in children between ages 10 and 13.
Social Phobias
Unlike specific phobias, social phobias include fear of public situations and scrutiny which leads to embarrassment or humiliation in the diagnostic criteria.
Rachman proposed three pathways to acquiring fear conditioning:
classical conditioning, vicarious acquisition and informational/instructional acquisition:
Much of the progress in understanding the acquisition of fear responses in phobias can be attributed to classical conditioning (Pavlovian model). When an aversive stimulus and a neural one are paired together, for instance when an electric shock is given in a specific room, the subject can start to fear not only the shock but the room as well. In behavioural terms, this is described as a conditioned stimulus (CS) (the room) that is paired with an aversive unconditioned stimulus (UCS) (the shock), which leads to a conditioned response (CR) (fear for the room) (CS+UCS=CR).
This direct conditioning model, though very influential in the theory of fear acquisition, is not the only way to acquire a phobia.

Regions of the brain associated with phobias
Beneath the lateral fissure in the cerebral cortex, the insula, or insular cortex, of the brain has been identified as part of the limbic system, along with cingulated gyrus, hippocampus, corpus callosum, and other nearby cortices. This system has been found to play a role in emotion processing and the insula, in particular, may contribute through its role in maintaining autonomic functions. Studies by Critchley et al. indicate the insula as being involved in the experience of emotion by detecting and interpreting threatening stimuli. Similar studies involved in monitoring the activity of the insula show a correlation between increased insular activation and anxiety.
In the frontal lobes, other cortices involved with phobia and fear are the anterior cingulate cortex and the medial prefrontal cortex. In the processing of emotional stimuli, studies on phobic reactions to facial expressions have indicated these areas to be involved in processing and responding to negative stimuli. The ventromedial prefrontal cortex has been said to influence the amygdala by monitoring its reaction to emotional stimuli or even fearful memories. Most specifically, the medial prefrontal cortex is active during extinction of fear and is responsible for long term extinction. Stimulation of this area decreases conditioned fear responses and so its role may be in inhibiting the amygdala and its reaction to fearful stimuli.
For the areas in the brain involved in emotion—most specifically fear— the processing and response to emotional stimuli can be significantly altered when one of these regions becomes lesioned or damaged. Damage to the cortical areas involved in the limbic system such as the cingulate cortex or frontal lobes have resulted in extreme changes in emotion.
Other types of damage include Klüver–Bucy syndrome and Urbach–Wiethe disease. In Klüver–Bucy syndrome, a temporal lobectomy, or removal of the temporal lobes results in changes involving fear and aggression. Specifically, the removal of these lobes results in decreased fear, confirming its role in fear recognition and response. Bilateral damage to the medial temporal lobes, which is known as Urbach–Wiethe disease exhibits similar symptoms of decreased fear and aggression, but also an inability to recognize emotional expressions, especially angry or fearful faces.
Although phobias are common, they don’t always cause considerable distress or significantly disrupt your life. For example, if you have a snake phobia, it may cause no problems in your everyday activities if you live in a city where you are not likely to run into one. On the other hand, if you have a severe phobia of crowded spaces, living in a big city would pose a problem.

If your phobia doesn’t really impact your life that much, it’s probably nothing to be concerned about. But if avoidance of the object, activity, or situation that triggers your phobia interferes with your normal functioning, or keeps you from doing things you would otherwise enjoy, it’s time to seek help.
Consider treatment for your phobia if:
– It causes intense and disabling fear, anxiety, and panic
– You recognize that your fear is excessive and unreasonable
– You avoid certain situations and places because of your phobia
– Your avoidance interferes with your normal routine or causes significant distress
– You’ve had the phobia for at least six months
There are various methods used to treat phobias. These methods include: systematic desensitization; progressive relaxation; virtual reality; modeling; medications; hypnotherapy and Therapy.
Cognitive behavioral therapy (CBT) can be beneficial. Cognitive behavioral therapy allows the patient to challenge dysfunctional thoughts or beliefs by being mindful of their own feelings with the aim that the patient will realize their fear is irrational. CBT may be conducted in a group setting. Gradual desensitisation treatment and CBT are often successful, provided the patient is willing to endure some discomfort. In one clinical trial, 90% of patients were observed to no longer have a phobic reaction after successful CBT treatment.
Hypnotherapy can be used alone and in conjunction with systematic desensitization to treatment phobias. Hypnotherapy can help people with phobias, resolve their issue, by uncovering the underlying cause of the phobia.
The cause of phobias may be from a past event that the patient does not remember.
When a traumatic event has occurred and the person who experienced it does not remember the event, the term is called repression.
Repression is a mechanism our mind uses to keep the memory of the trauma out of our conscious mind until we are ready to deal with it. Hypnotherapy may also eliminate the conditioned responses that occur during different situations: the phobic object is within eyesight of the patient, the patient is placed in a phobic situation, or the patient is attempting to complete a phobic task.
Patients are first placed into a hypnotic trance (i.e. an extremely relaxed state). The unconscious can be retrieved during the hypnotic trance. This state always for patients to be open to suggestion, which helps bring about a desired change. Addressing old memories consciously helps individuals understand the event and see the event in a way which is no longer threatening.
When it comes to treating phobias, self-help strategies and therapy can both be effective. What’s best for you depends on a number of factors, including the severity of your phobia, your insurance coverage, and the amount of support you need.
As a general rule, self-help is always worth a try. The more you can do for yourself, the more in control you’ll feel—which goes a long way when it comes to phobias and fears. However, if your phobia is so severe that it triggers panic attacks or uncontrollable anxiety, you may want to get additional support.
The good news is that therapy for phobias has a great track record. Not only does it work extremely well, but you tend to see results very quickly—sometimes in as a little as one to four sessions. Support doesn’t have to come in the guise of a professional therapist. Just having someone to hold your hand or stand by your side as you face your fears can be extraordinarily helpful.

While it’s natural to feel scared or anxious as you face your phobia, you should never feel overwhelmed by these feelings. If you start to feel overwhelmed, immediately back off. You may need to spend more time learning to control feelings of anxiety (see the relaxation techniques below), or you may feel more comfortable working with a therapist.
Medications can help regulate the apprehension and fear that comes from thinking about or being exposed to a particular fearful object or situation.
Antidepressant medications such as SSRIs or MAOIs may be helpful in some cases of phobia.
SSRIs (antidepressants) act with serotonin, a neurotransmitter in the brain.
Since serotonin impacts mood, patients may be prescribed an antidepressant. Another type of medication used for treating patients with phobias are sedatives.
Benzodiazepines are sedatives, which can help patients relax by reducing the amount of anxiety they feel. Benzodiazepines may be useful in acute treatment of severe symptoms, but the risk-benefit ratio is against their long-term use in phobic disorders. Though once believed to be highly addictive, these prescriptions have been recently shown as addictive if used with negative behaviors (i.e. alcohol abuse). Despite this recent positive finding, benzodiazepines should be used with caution.
Beta blockers are another medication that can be used as a treatment for phobias. Beta blockers stop the stimulating effects of adrenaline in a person’s body. These effects include: sweating, increased heart rate, elevated blood pressure, tremors, and the feeling of a pounding heart. By taking beta blockers before a phobic event, these symptoms are decreased, causing the event to be less frightening.
