PHOBIAS
About Your
DiagnosisIn simple terms, a phobia is
a fear of some behavior or some event. This fear is often accompanied by
physical signs such as rapid heart rate, shortness of breath, feeling of a lump
in the throat, tightness in the chest, and diarrhea. Individuals will often go
to great lengths to avoid the stimulus that causes their fear or phobia, if that
is possible. It is only when such fears become so intense that they interfere
with social and occupational functioning that the attention of a psychiatrist is
sought. In social phobia, there is a significant and long-lasting fear of one or
more social situations in which individuals might be exposed to unfamiliar
people or to possible scrutiny by
others.Living With Your
DiagnosisIndividuals with a social
phobia have a fear that they will act in a humiliating or embarrassing way. Such
activities as writing a check in public, eating in a restaurant, and using a
public restroom facility are examples of behavior that individuals with social
phobia will try to avoid. If, however, these situations cannot be avoided,
exposure to them almost always creates significant anxiety, which may even lead
to a panic attack. Individuals with social phobia realize that the fear they are
experiencing is unreasonable and excessive, but they are still unable to control
it. Their only relief comes from avoiding the specific activity that they fear.
An individuals’ occupation may enhance exposure to the phobic event, such
as individuals who work in a bank, or who are accountants or secretaries, where
writing in full view of others may be part of the job. In that case, there can
be a significant impairment in their occupational functioning. The most common
phobias are the specific phobias. Individuals with specific phobias have a
marked, long-lasting fear which is excessive or unreasonable that is caused by
the presence of a specific object or situation. The most common objects r
situations that provoke specific phobias are fear of flying, fear of heights
(acrophobia), fear of spiders (arachniphobia), fear of strangers (xenophobia),
or fear of receiving an injection, fear of seeing blood, and fear of being in
small spaces (claustrophobia). Exposure to one of these events or situations
causes significant anxiety that can escalate into a full-blown panic attack.
Therefore individuals try to avoid whatever might be causing the fear or
phobia. In some situations, this is fairly easy. For those individuals who fear
snakes, being a city dweller will greatly minimize their exposure to snakes.
Therefore, avoidance of them will be easy. Other situations obviously are hard
to avoid. Individuals who have a fear of closed in places often cannot ride an
elevator, and cannot have certain procedures done that involve closed in areas,
such as a magnetic resonance imaging (MRI) scan. These individuals will have
more trouble avoiding phobic situations than those who have a specific fear of
animals or blood. Phobias are among the most common of all psychiatric
disorders. The specific phobias are more common in women than in men, although
there are some differences in terms of types of phobia in each group. The
incidence of social phobias in males
andfemales is about the same. Most phobias
begin in the middle-to-late teenage years, but often phobias of animals, blood,
storms, and water begin in early childhood. Phobias of height tend to begin in
the teens, whereas situational phobias such as claustrophobia begin in the late
teens to middle 20s. If the occurrence rates of specific phobias in males and
females are compared, we find that women are much more likely than men to have a
fear of (1) spiders, bugs, mice, and snakes; (2) public transportation, such as
buses and planes; (3) elevators; (4)water (being in a swimming pool or lake);
(5) storms; and (6) closed places. Males and females are equally fearful of
heights. Men and women are equally affected by a fear of speaking to strangers
or meeting new people, and by a fear of eating in front of others. Women are
only slightly more likely to have a fear of public speaking. There is no
specific factor that may cause a phobia, although there probably is a genetic
component because these disorders tend to run in families. Some phobias begin
after a traumatic event, but many patients cannot recall the specific onset of
their phobia. The onset of the phobia or fear can be sudden or gradual.
TreatmentIn
the treatment of phobia, the main goal is to decrease fear to a level that no
longer causes significant distress, and to minimize the need to avoid the object
or situation the patient fears, so that the ability to function is no longer
impaired. Treatment also serves to improve some of the skills that phobic
avoidance may have prevented the individual from obtaining or developing
adequately, such as driving or social skills. Typically, an effective treatment
for social phobia lasts several months, although the treatment of some specific
social phobias, such as public speaking, may take less time. Specific phobias
can be treated relatively quickly. In fact, the vast majority of individuals
with phobias of animals, blood, or injections are able to overcome their phobias
in one session of behavioral treatment. Phobias can be effectively treated by
using medications, behavioral techniques, or both. There is a marked difference
in the response of social phobia and specific phobias to medication. Medication
has generally been ineffective for the specific phobias. If medications are
used, they are generally used to treat the consequences of the phobia, such as
panic disorder, in which case the antidepressant imipramine and the serotonin
drugs Paxil and Prozac are used. Therefore, medications that are effective for
panic disorder may prove to be effective for situational phobias as well. In
contrast to the specific phobias, the social phobias have been treated
successfully with medication. The monoamine oxidase (MAO) inhibitor
antidepressants, such as phenelzine (Nardil), are very effective for many
patients with social phobias. The benzodiazepines such as clonazepam (Klonopin)
and alprazolam (Xanax) have also shown some beneficial effects, as have the
beta-blockers such as Atenolol and Inderal, which are used extensively for
performance anxiety. Often, Inderal or Atenolol will be given to individuals who
are stage performers just before their activity. These drugs decrease
significantly some of the signs of anxiety, especially tachycardia or a sense of
the heart pounding. In contrast to drug therapy, numerous studies have shown
that exposure-based treatments are effective for treating patients with specific
phobias, including fear of blood, injections, dentists, animals, enclosed
places, flying, heights, and choking. Also, the way in which individuals are
exposed to these specific fears may make a difference in how well they respond
to treatment. Exposure seems to work best when sessions are spaced close
together, and prolonged exposure seems to be more effective than exposure for a
short duration. During exposure to the object that is feared, patients should be
discouraged from engaging in avoidance techniques such as distraction or
thinking of something else, or overuse of different safety techniques such as
being accompanied by someone during exposure. Gradual exposure to the feared
object is the most common behavioral treatment for phobias and is very effective
for the specific phobias. For instance, an individual with a fear of driving may
initially spend some time washing a car, staying in the garage with a car, and
then gradually advance to sitting in the car in the garage, sitting in the car
in the driveway,backing the car out of the
driveway, and so on. This gradual exposure to the feared event can offer the
individual ways of dealing with the anxiety that comes from being near the
feared object. Biofeedback often is helpful in helping the individual control
his heart rate and breathing when exposed
tothe object.
In summary, there are three basic
types of phobias: (1) agoraphobia, (2) social phobias, and (3) specific phobias.
Agoraphobia is a fear of wide open spaces and the fear of being trapped without
being able to return home. Social phobias are fears of performing certain
activities in public or areas where the activity may be witnessed; for example,
writing checks in public or eating in public. Specific phobias are fears of
specific objects or situations, such as a fear of flying, fear of driving, fear
of animals, fear of snakes, fear of strangers, fear of heights, and fear of
closed places. It seems that the social phobias respond very well to medication,
in particular to such drugs as the MAO inhibitor, Nardil. In contrast, the
specific phobias respond much better to behavioral techniques, such as gradual
exposure to the object and rating the anxiety produced by that, and then using
biofeedback, hypnosis, or some other technique to diminish the anxiety. There
are side effects that can result from the medications used to treat phobias. In
particular, patients who are taking the MAO inhibitor, Nardil, must follow
certain dietary restrictions as well as avoid certain medications. Such patients
cannot eat aged cheeses or fava beans and cannot drink red wine, especially
Chianti wine. Also, patients should avoid the use of medications such as
Demerol, any epinephrine-containing compounds, and cocaine while taking the MAO
inhibitor. Patients must also avoid using any other antidepressants such as
imipramine, Elavil, or Prozac within 2 weeks of being on the MAO inhibitor. If
these dietary and medication restrictions are not followed, the MAO inhibitor
may cause a severe hypertensive crisis. There-fore, patients who already have
high blood pressure should not take this medication. Of course, the
benzodiazepines such as Klonopin and Ativan can decrease respirations, so they
should not be used in patients who have serious lung disease. They also tend to
produce sedation, which may impair driving or activity that requires delicate
machinery. The benzodiazepines have the additional problem of being potentially
addictive. The tricyclic antidepressants such as imipramine can cause blurred
vision, dry mouth, possible constipation, rapid heartbeat, and in some cases
oversedation. The
DOsIf you do have a phobic disorder,
it is very important to report this condition to your physician. Many
individuals, especially some males, are embarrassed to admit their fear to
certain objects. Specific phobias, however, can be successfully treated, often
in a single session. Because phobias are anxiety disorders, it is important to
avoid undo stress. It is also important to minimize the use of stimulants,
including caffeine and sugar in your diet. Getting plenty of exercise often
provides an outlet for the anxiety associated with phobias, as well as relieving
some of the consequences of phobias. If you do have a phobia of specific objects
that can be successfully avoided without significant impairment of your
functioning, such as snakes, then you should do
so.The
DON’TsYou should not take any
medications without consulting with your physician. Many over-thecounter (OTC)
medications have some stimulant properties and can increase the anxiety
associated with phobias. Such OTC drugs as Valerian Root may interact with
antidepressants. When to Call Your
DoctorYou should call your physician
if you notice phobic attacks occurring more often, if you have physical
complications from increased anxiety, or if you become depressed and suicidal
because of a phobic
condition.Websites:http://www.cts.com/~health
