Anxiety disorder is a blanket term covering several different forms
of abnormal, pathological anxiety, fears, phobias and nervous conditions
that may come on suddenly or gradually over a period of several
years, and may impair or prevent the pursuing of normal daily routines.
Anxiety and fear are ever-present emotions in all people. The
terms anxiety and fear have specific scientific meanings, but common
usage has made them interchangeable. For example, a phobia is a
kind of anxiety that is also defined in the Diagnostic and Statistical
Manual of Mental Disorders, 4th edition (DSM-IV-TR) as a "persistent
or irrational fear." Fear is defined as an emotional and physiological
response to a recognized external threat (eg, a runaway car or an
impending crash in an airplane).
Anxiety is an unpleasant emotional state, the sources of which
are less readily identified. It is frequently accompanied by physiological
symptoms that may lead to fatigue or even exhaustion. Because fear
of recognized threats causes similar unpleasant mental and physical
changes, patients use the terms fear and anxiety interchangeably.
Thus, there is little need to strive to differentiate anxiety from
fear. However, distinguishing among different anxiety disorders
is important, since accurate diagnosis is more likely to result
in effective treatment and a better prognosis.
A good assessment is essential for the initial diagnosis of an
anxiety disorder, preferably using a standardized interview or questionnaire
procedure alongside expert evaluation and the views of the persons
themselves. There should be a medical examination in order to identify
possible medical conditions that can cause the symptoms of anxiety.
A family history of anxiety disorders is suggestive of the possibility
of an anxiety disorder.
Panic disorder
In panic disorder, a person suffers brief attacks of intense terror
and apprehension that cause trembling and shaking, dizziness, and
difficulty breathing. One who is often plagued by sudden bouts of
intense anxiety might be said to be afflicted by this disorder.
The American Psychiatric Association (2000) defines a panic attack
as fear or discomfort that arises abruptly and peaks in 10 minutes
or less.
Although panic attacks sometimes seem to occur out of nowhere,
they generally happen after frightening experiences, prolonged stress,
or even exercise. Many people who have panic attacks (especially
their first one) think they are having a heart attack and often
end up at the doctor or ER. Even if the tests all come back normal
the person will still worry, with the physical manifestations of
anxiety only reinforcing their fear that something is wrong with
their body. Extreme awareness of every little thing that happens
or changes with their body can make for a stressful time.
Normal changes in heartbeat, such as when climbing a flight of
stairs will be noticed by a panic sufferer and lead them to think
something is wrong with their heart or they are about to have another
panic attack. Some begin to worry excessively and even quit jobs
or refuse to leave home to avoid future attacks. Panic disorder
can be diagnosed when several apparently spontaneous attacks lead
to a persistent concern about future attacks.
Phobias
This category involves a strong, irrational fear and avoidance of
an object or situation. The person knows the fear is irrational,
yet the anxiety remains. Phobic disorders differ from generalized
anxiety disorders and panic disorders because there is a specific
stimulus or situation that elicits a strong fear response. A person
suffering from a phobia of spiders might feel so frightened by a
spider that he or she would try to jump out of a speeding car to
get away from one.
People with phobias have especially powerful imaginations, so
they vividly anticipate terrifying consequences from encountering
such feared objects as knives, bridges, blood, enclosed places,
certain animals or situations. These individuals generally recognize
that their fears are excessive and unreasonable but are generally
unable to control their anxiety.
Social anxiety disorder
Social anxiety disorder is also known as social phobia. Individuals
with this disorder experience intense fear of being negatively evaluated
by others or of being publicly embarrassed because of impulsive
acts. Almost everyone experiences "stage fright" when
speaking or performing in front of a group. But people with social
phobias become so anxious that performance is out of the question.
In fact, their fear of public scrutiny and potential humiliation
becomes so pervasive that normal life can become impossible (den
Boer 2000; Margolis & Swartz, 2001). Another social phobia is
love-shyness, which most adversely affects certain men. Those afflicted
find themselves unable to initiate intimate adult relationships
(Gilmartin 1987).
Obsessive-compulsive disorder
Obsessive compulsive disorder is a type of anxiety disorder primarily
characterized by obsessions and/or compulsions. Obsessions are distressing,
repetitive, intrusive thoughts or images that the individual often
realizes are senseless. Compulsions are repetitive behaviours that
the person feels forced or compelled into doing, in order to relieve
anxiety. The OCD thought pattern may be likened to superstitions:
if X is done, Y won't happen--in spite of how unlikely it may be
that doing X will actually prevent Y, if Y is even a real threat
to begin with. A common example of this behaviour would be obsessing
that one's door is unlocked, which may lead to compulsive constant
checking and rechecking of doors. Often the process seems much less
logical. For example, the compulsion of walking in a certain pattern
may be employed to alleviate the obsession that something bad is
about to happen.
Post-traumatic stress disorder
Post-traumatic stress disorder is an anxiety disorder which results
from a traumatic experience, such as being involved in battle. The
sufferer may experience flashbacks and other symptoms.
Treatment
Anxiety disorders are often debilitating chronic conditions, which
can be present from an early age or begin suddenly after a triggering
event. They are prone to flare up at times of high stress.
Many of these disorders can also be treated (with or without adjuctive
pharmaceutical therapy) with the aid of a good counselor and behavioural
therapies such as cognitive therapy.
Mainstream treatment for anxiety consists of the prescription of
anxiolytic agents and/or referral to a cognitive-behavioural therapist.
There are indications that a combination of the two can be more
effective than either one alone.
A number of drugs are used to treat these disorders. These include
benzodiazepines and antidepressants of most of the main classes
(SSRI, TCAs, MAOIs), and possibly Quetiapine.
