Treatment can
bring significant relief to 70 to 90 percent of people with
panic disorder, and early treatment can help keep the disease
from progressing to the later stages where agoraphobia develops.
Before undergoing
any treatment for panic disorder, a person should undergo
a thorough medical examination to rule out other possible
causes of the distressing symptoms. This is necessary
because a number of other conditions, such as excessive
levels of thyroid hormone, certain types of epilepsy,
or cardiac arrhythmias, which are disturbances in the
rhythm of the heartbeat, can cause symptoms resembling
those of panic disorder.
Several effective
treatments have been developed for panic disorder and
agoraphobia. In 1991, a conference held at the National
Institutes of Health (NIH) under the sponsorship of the
National Institute of Mental Health and the Office of
Medical Applications of Research, surveyed the available
information on panic disorder and its treatment. The conferees
concluded that a form of psychotherapy called cognitive-behavioral
therapy and medications are both effective for panic disorder.
A treatment should be selected according to the individual
needs and preferences of the patient, the panel said,
and any treatment that fails to produce an effect within
6 to 8 weeks should be reassessed.
Cognitive-Behavioral
Therapy. This is a combination of cognitive therapy,
which can modify or eliminate thought patterns contributing
to the patient's symptoms, and behavioral therapy, which
aims to help the patient to change his or her behavior.
Typically the
patient undergoing cognitive-behavioral therapy meets
with a therapist for 1 to 3 hours a week. In the cognitive
portion of the therapy, the therapist usually conducts
a careful search for the thoughts and feelings that accompany
the panic attacks. These mental events are discussed in
terms of the "cognitive model" of panic attacks.
The cognitive
model states that individuals with panic disorder often
have distortions in their thinking, of which they may
be unaware, and these may give rise to a cycle of fear.
The cycle is believed to operate this way: First the individual
feels a potentially worrisome sensation such as an increasing
heart rate, tightened chest muscles, or a queasy stomach.
This sensation may be triggered by some worry, an unpleasant
mental image, a minor illness, or even exercise. The person
with panic disorder responds to the sensation by becoming
anxious. The initial anxiety triggers still more unpleasant
sensations, which in turn heighten anxiety, giving rise
to catastrophic thoughts. The person thinks "I am having
a heart attack" or "I am going insane," or some similar
thought. As the vicious cycle continues, a panic attack
results. The whole cycle might take only a few seconds,
and the individual may not be aware of the initial sensations
or thoughts.
Proponents
of this theory point out that, with the help of a skilled
therapist, people with panic disorder often can learn
to recognize the earliest thoughts and feelings in this
sequence and modify their responses to them. Patients
are taught that typical thoughts such as "That terrible
feeling is getting worse!" or "I'm going to have a panic
attack" or "I'm going to have a heart attack" can be replaced
with substitutes such as "It's only uneasiness—it will
pass" that help to reduce anxiety and ward off a panic
attack. Specific procedures for accomplishing this are
taught. By modifying thought patterns in this way, the
patient gains more control over the problem.
In cognitive
therapy, discussions between the patient and the therapist
are not usually focused on the patient's past, as is the
case with some forms of psychotherapy. Instead, conversations
focus on the difficulties and successes the patient is
having at the present time, and on skills the patient
needs to learn.
The behavioral
portion of cognitive-behavioral therapy may involve systematic
training in relaxation techniques. By learning to relax,
the patient may acquire the ability to reduce generalized
anxiety and stress that often sets the stage for panic
attacks.
Breathing exercises
are often included in the behavioral therapy. The patient
learns to control his or her breathing and avoid hyperventilation—a
pattern of rapid, shallow breathing that can trigger or
exacerbate some people's panic attacks.
Another important
aspect of behavioral therapy is exposure to internal sensations
called interoceptive exposure. During interoceptive exposure
the therapist will do an individual assessment of internal
sensations associated with panic. Depending on the assessment,
the therapist may then encourage the patient to bring
on some of the sensations of a panic attack by, for example,
exercising to increase heart rate, breathing rapidly to
trigger lightheadedness and respiratory symptoms, or spinning
around to trigger dizziness. Exercises to produce feelings
of unreality may also be used. Then the therapist teaches
the patient to cope effectively with these sensations
and to replace alarmist thoughts such as "I am going to
die," with more appropriate ones, such as "It's just a
little dizziness—I can handle it."
Another important
aspect of behavioral therapy is "in vivo" or real-life
exposure. The therapist and the patient determine whether
the patient has been avoiding particular places and situations,
and which patterns of avoidance are causing the patient
problems. They agree to work on the avoidance behaviors
that are most seriously interfering with the patient's
life. For example, fear of driving may be of paramount
importance for one patient, while inability to go to the
grocery store may be most handicapping for another.
Some therapists
will go to an agoraphobic patient's home to conduct the
initial sessions. Often therapists take their patients
on excursions to shopping malls and other places the patients
have been avoiding. Or they may accompany their patients
who are trying to overcome fear of driving a car.
The patient
approaches a feared situation gradually, attempting to
stay in spite of rising levels of anxiety. In this way
the patient sees that as frightening as the feelings are,
they are not dangerous, and they do pass. On each attempt,
the patient faces as much fear as he or she can stand.
Patients find that with this step-by-step approach, aided
by encouragement and skilled advice from the therapist,
they can gradually master their fears and enter situations
that had seemed unapproachable.
Many therapists
assign the patient "homework" to do between sessions.
Sometimes patients spend only a few sessions in one-on-one
contact with a therapist and continue to work on their
own with the aid of a printed manual.
Often the patient
will join a therapy group with others striving to overcome
panic disorder or phobias, meeting with them weekly to
discuss progress, exchange encouragement, and receive
guidance from the therapist.
Cognitive-behavioral
therapy generally requires at least 8 to 12 weeks. Some
people may need a longer time in treatment to learn and
implement the skills. This kind of therapy, which is reported
to have a low relapse rate, is effective in eliminating
panic attacks or reducing their frequency. It also reduces
anticipatory anxiety and the avoidance of feared situations.
Treatment
with Medications. In this treatment approach, which
is also called pharmacotherapy, a prescription medication
is used both to prevent panic attacks or reduce their
frequency and severity, and to decrease the associated
anticipatory anxiety. When patients find that their panic
attacks are less frequent and severe, they are increasingly
able to venture into situations that had been off-limits
to them. In this way, they benefit from exposure to previously
feared situations as well as from the medication.
The selective
serotonin reuptake inhibitors (SSRIs) are now the first
line of medication treatment for panic disorder. Other
commonly used medications are the tricyclic antidepressants,
the high-potency benzodiazepines, and the monoamine oxidase
inhibitors (MAOIs). Determination of which drug to use
is based on considerations of safety, efficacy, and the
personal needs and preferences of the patient.
Scientists
supported by NIMH are seeking ways to improve drug treatment
for panic disorder. Studies are underway to determine
the optimal duration of treatment with medications, who
they are most likely to help, and how to moderate problems
associated with withdrawal.
What
to Do if a Family Member Has an Anxiety Disorder
- Don’t make
assumptions about what the affected person needs; ask
them.
- Be predictable;
don’t surprise them.
- Let the
person with the disorder set the pace for recovery.
- Find something
positive in every experience. If the affected person
is only able to go partway to a particular goal, such
as a movie theater or party, consider that an achievement
rather than a failure.
- Don’t enable
avoidance: negotiate with the person with panic disorder
to take one step forward when he or she wants to avoid
something.
- Don’t sacrifice
your own life and build resentments.
- Don’t panic
when the person with the disorder panics.
- Remember
that it’s all right to be anxious yourself; it’s natural
for you to be concerned and even worried about the person
with the disorder.
- Be patient
and accepting, but don’t settle for the affected person
being permanently disabled.
- Say: "You
can do it no matter how you feel. I am proud of you.
Tell me what you need now. Breathe slow and low. Stay
in the present. It’s not the place what’s bothering
you, it’s the thought. I know that what you are feeling
is painful, but it’s not dangerous. You are courageous."
Don’t say:
"Relax. Calm down. Don’t be anxious. Let’s see if you
can do this (i.e., setting up a test for the affected
person). You can fight this. What should we do next? Don’t
be ridiculous. You have to stay. Don’t be a coward.

Combination
Treatments. Many believe that a combination of medication
and cognitive-behavioral therapy represents the best alternative
for the treatment of panic disorder. The combined approach
is said to offer rapid relief, high effectiveness, and
a low relapse rate. However, there is a need for more
research studies to determine whether this is in fact
the case.
Comparing medications
and psychological treatments, and determining how well
they work in combination, is the goal of several NIMH-supported
studies. The largest of these is a 5-year clinical trial
that will include 480 patients and involve four centers
at the State University of New York at Albany, Cornell
University, Hillside Hospital/Columbia University, and
Yale University. This study is designed to determine how
treatment with imipramine compares with a cognitive-behavioral
approach, and whether combining the two yields benefits
over either method alone.
Psychodynamic
Treatment. This is a form of "talk therapy" in which
the therapist and the patient, working together, seek
to uncover emotional conflicts that may underlie the patient's
problems.
Although psychodynamic
approaches may help to relieve the stress that contributes
to panic attacks, they do not seem to stop the attacks
directly. In fact, there is no scientific evidence that
this form of therapy by itself is effective in helping
people to overcome panic disorder or agoraphobia. However,
if a patient's panic disorder occurs along with some broader
and pre-existing emotional disturbance, psychodynamic
treatment may be a helpful addition to the overall treatment
program.
