The
progression of my checking rituals increased my anxiety, rather than alleviating
it. This is because the rituals only produce short-term anxiety relief.
My obsessions and compulsions usually started with a somewhat reasonable
worry. Many people with OCD have obsessions that are completely out of
character for the person to have, such as thoughts of harming a parent
or child. The compulsion is meant to relieve the distress that accompanies
an obsession. Often it is a ritual unrelated to the obsession, such as
tapping, counting, saying certain words or praying.
Treatment
of OCD
OCD
is most effectively treated with a combination of behavior therapy and
medications. Studies have shown that a combination of behavior therapy
and medication therapy produce better results than either treatment used
alone. Although more difficult and time consuming, behavior therapy has
demonstrated more lasting results. Relapse is frequent when medication
is withdrawn.
Medication
Therapy
The
medications most commonly used in treating OCD are antidepressants. The
five drugs proven to be useful in OCD treatment are fluvoxamine (Luvox),
fluoxetine (Prozac), sertraline (Zoloft), paroxetine (Paxil), and clomipramine
(Anafranil). Venlafaxine (Effexor) may be effective, but more study is
needed.
Anafranil
is an older medication, a tricyclic antidepressant. It is a serotonin
reuptake inhibitor (SRI), but it is not selective for serotonin; as a
result it has effects on other chemical messengers besides serotonin and
has a wider variety of side effects. The fact that Anafranil was effective
in treating the symptoms of OCD while other tricyclic antidepressants
were not was one of the first important clues to the role of serotonin
in this disease. Luvox, Prozac, Zoloft, and Paxil are selective serotonin
reuptake inhibitors (SSRI's). These medications are not chemically related,
but they all work by inhibiting the reuptake of serotonin. Serotonin is
one of the neurotransmitter chemicals that nerve cells in the brain use
to communicate with each other. These neurotransmitters are active when
they are present in the synaptic cleft between nerve cells. Transmission
is ended when the chemicals are taken back up into the transmitting cell.
The SRI's and SSRI's slow the reuptake of serotonin, making it more available
to the receiving cell and prolonging its effect on the brain.
Sometimes
a patient will not respond to the first medication, and will have to try
two or more of the SSRI's before finding one that works for him. Side
effects are common with all of these medications. Rarely, patients taking
any antidepressant can become manic or psychotic, or have seizures. The
SSRI's seem to have less frequent side effects than Anafranil. The nurse
should observe for signs of impaired clotting, such as bruising or nosebleeds,
because serotonin is involved in platelet function.
Seizure
rates are lower and the risk of overdose is lower with the SSRI's than
with Anafranil. They have few anticholinergic side effects and they do
not appear to alter cardiac conduction. Side effects of SSRI's include
weight gain, restlessness, impulsiveness, sleepiness, insomnia, a heightened
sense of energy, headaches, and impaired clotting.
Gastrointestinal
side effects include nausea, abdominal pain, loss of appetite, heartburn,
and diarrhea. Self-injurious behavior and suicidal thoughts have been
reported with fluoxetine. The SSRI's are processed by the liver, and therefore
can interact with other medications metabolized in the liver. This can
cause an elevation of both drugs and increased side effects. This interaction
seems to be more likely to occur with fluoxetine and least likely with
sertraline.
Anafranil
may cause more pronounced side effects including anticholinergic symptoms
such as dry mouth, constipation, excessive sweating and urinary retention.
Other side effects include fatigue, drowsiness, increased appetite, weight
gain, tachycardia, dizziness, tremors, seizures, mania, agitation, memory
problems, difficulty concentrating, sedation, and hypotension. Increased
incidence of seizures at doses above 250 mg/day has been reported. Encourage
patients to tell their doctors about side effects: adjusting the dosage,
or changing the time of day that the medication is taken may relieve many
of them.
Although
not required, electrocardiograms are often done before beginning treatment
with Anafranil, when the target dose is reached, and periodically during
treatment. Anafranil can affect electrical conduction through the heart.
Yearly liver function tests may be done. Anafranil should be discontinued
slowly; abrupt withdrawal can cause nausea, vomiting, hyperthermia, headache,
sleep problems, and malaise. Combining alcohol with Anafranil may trigger
aggressive behavior.
The
SSRI's and SRI's often produce sexual side effects in both men and women.
These include lowered sexual drive, delayed ability to have an orgasm,
and complete inability to have an erection or orgasm. Some patients have
increased interest in sexual activity. Spontaneous orgasms while yawning
have been reported. Notify your patient of these side effects, and encourage
him to discuss them with his doctor if he experiences them. Some patients
have been able to reduce sexual side effects and enjoy sexual activity
on the weekends by stopping the medication on Fridays and Saturdays. This
is not as effective with Prozac because it is longer acting. Patients
should not adjust their medications without their doctor's approval and
supervision.
High
dosages of medication are usually needed to obtain anti-obsessional effects.
Recommended dosages are: Luvox - up to 300 mg/day; Prozac - 40-80 mg/day;
Zoloft - up to 200 mg/day; Paxil - 40-60 mg/day; and Anafranil - up to
250 mg/day. Some patients are very sensitive to even the lowest dosages.
Starting
with the lowest dose possible, even breaking pills in half, and gradually
increasing the dosage, may be effective. Prozac comes in a liquid form
which allows patients to start very low (1-2 mg/day). A very small number
of patients who have not had a reduction in OCD symptoms at large dosages,
have had good results with extremely low doses.
It
is best to avoid anti-obsessional medications during pregnancy and breast-feeding.
Long-term effects on the fetus or infant are not known at this time. Risk
to the fetus would be highest during the first trimester, so medication
should at least be avoided during this time.
Anafranil
should be avoided in elderly patients because it can interfere with thinking
and cause or worsen confusion in the elderly. Tachycardia, dry mouth,
constipation, urinary retention, and memory problems are other side effects
that can make it a poor choice for the elderly. Prozac, Zoloft, Luvox,
and Paxil can be used at greatly reduced dosages. With all of the anti-obsessional
medications, elderly patients are more likely than others are to experience
agitation, restlessness, nervousness, confusion, and changes in heart
rhythm and rate. Special caution should be used when giving these medications
to patients with heart disease. They may need close monitoring and frequent
cardiograms. Patients with liver disease need closer monitoring of dosage.
Some patients with liver disease will not be able to take these medications.
Dosage adjustment may be needed if other medications metabolized in the
liver are being taken.
Anti-obsessional
medications take up to 12 weeks to begin working. During the first few
weeks, patients may have many side effects, but no relief of OCD symptoms.
Even psychiatrists may be tempted to give up on the medication too soon,
since it usually takes only four to six weeks for depressed patients to
improve. When these medications are stopped, they should be withdrawn
gradually.
Improvement
following adequate OCD drug treatment is frequently only partial, and
from 20 to 30% of cases may be refractory to treatment. Two or more SRI's
may be combined to get the best results. If this is done, the Anafranil
dose should be kept low because the blood level of Anafranil can be greatly
increased by adding another medication. Studies have been conducted using
neuroleptic medications (haloperidol and risperidone) in combination with
an SRI. This may be particularly effective in patients with OCD accompanied
by tics, Tourette's disorder, body dysmorphic disorder, or trichotillomania
(compulsive pulling out of one's own hair). The SRI's and the neuroleptics
can compete for metabolism in specific hepatic pathways, so the rate of
metabolism can be influenced. This can result in a net increase in the
doses of both medications. Oculogyric crisis (eyes fixed upward and involuntary
tonic movements) has been reported in two children treated with paroxetine
and a neuroleptic. The addition of a neuroleptic may cause additional
side effects, such as cognitive dulling, fatigue, weight gain, akathisia,
and tardive dyskinesia. Quinidine-like cardiac effects can occur with
the combination of SRI's and neuroleptics. An electrocardiogram should
be performed, especially in patients over 40 years old, when a cardiac
history is present, or when pimozide is combined with a tricyclic antidepressant,
such as Anafranil.
Monoamine
oxidase inhibitors (MAOI's), such as tranylcypromine (Parnate) and phenelzine
(Nardil), are occasionally used to treat OCD. MAOI's may be effective
in OCD patients with comorbid panic, anxiety, or depressive disorders.
Certain
foods and medications can cause serious side effects, and even fatal reactions,
if they are taken with MAOI's. Foods high in tyramine are to be avoided.
These include wine, beer, alcohol, soda, orange juice, coffee, tea, aged
cheese, sour cream, yogurt, pickled products, smoked herring, brains,
liver, avocados, tomatoes, raisins, bananas, figs, broad beans, eggplant,
peanut butter, meat tenderizers, vanilla, cocoa, chocolate, and caffeine.
Instruct the patient not to take any medications, including over the counter
medicine, amino acids (such as tyrosine, tryptophan, D-L phenylalanine,
and phenylalanine), or other supplements, without consulting the doctor.
Side
effects of MAOI's include dizziness, drowsiness, anorexia, orthostatic
hypotension, hypertension, and dysrhythmia. Less common side effects include
anemia, confusion, headache, anxiety, tremors, CNS stimulation, weakness,
hyperreflexia, mania, insomnia, fatigue, weight gain, constipation, dry
mouth, nausea, vomiting, diarrhea, urinary frequency, change in libido,
rash, flushing, increased perspiration, hypertensive crisis, and blurred
vision. Instruct the patient to report immediately: headache, palpitation,
dysrhythmia, or prodromal signs of hypertensive crisis.
MAOI's
are contraindicated in the elderly and in those with hypertension, CHF,
severe hepatic disease, pheochromocytoma, severe renal disease, and severe
cardiac disease. They should not be given to patients who may not be compliant
with food and medication restrictions. Hepatic studies and other lab work
may be done on a routine basis.
Combined
with SSRI's, SRI's, or buspirone, MAOI's are particularly dangerous, and
can even be fatal. One must be stopped for at least two weeks before starting
the other. Adverse reactions have been reported up to four weeks after
discontinuing MAOI's. Prozac is longer lasting, so the interval is five
weeks. Hypertensive crisis or serotonergic syndrome can result from combining
these medications with an MAOI, or from inadequate time between trials.
Serotonergic
syndrome, or serotonin syndrome, is characterized by fever, muscular rigidity,
vital sign fluctuations, agitation, delirium, or coma. All of these symptoms
need not be present. If your patient is on a MAOI, make certain he understands
the side effects, special diet restrictions, and the importance of not
taking unprescribed medications. Serotonin syndrome can also occur, usually
more mildly, when anti-obsessive medications are added to L-tryptophan,
lithium, fenfluramine, or buspirone.
Alcohol
can have a greater effect on individuals taking anti-obsessional medications.
It is not known if alcohol can counteract some of the therapeutic effects
of these medications.
Behavior
Therapy
Completion
of a course of behavior therapy appears to work as well as medication
for the treatment of OCD. Research is finding that, over time, behavior
therapy can change a person's brain chemistry. Patients tend to stay in
remission long-term, requiring only occasional refresher sessions.
The
complication is that behavior therapy requires great motivation and cooperation
on the patient's part. When used together, medication and behavior therapies
complement each other. Medication alters the level of serotonin relatively
quickly, while behavior therapy helps modify behavior by teaching the
patient how to resist compulsions and obsessions. Exposure and response
prevention are the principal behavioral techniques for treating OCD. Thought
stopping, desensitization, flooding, implosion therapy, and aversive conditioning
have also been used.
The
purpose of exposure is to decrease the anxiety and discomfort
associated with obsessions through habituation. This may be done by desensitization
with brief imaginal exposure or prolonged exposure to the real-life ritual-evoking
stimuli. For example, the person may be exposed to garbage or other contaminated
objects without relieving the anxiety by washing his hands. As the person
realizes that the feared consequences will not occur, the anxiety decreases.
This is called habituation. The purpose of response prevention
is to decrease the frequency of rituals. Patients are faced with feared
stimuli without practicing rituals, such as hand washing or excessive
checking. At first, the patient may be allowed to delay performing a ritual,
working gradually towards resisting the compulsion.
Relaxation
is usually not used during exposure and response prevention exercises
because it interferes with progress. It is important not to let coping
tactics lead to avoidance. However, some patients do find applied relaxation
techniques to be helpful. I find practicing relaxation techniques to be
helpful between behavior therapy exercises.
A
graded hierarchy of anxiety producing activities and situations is constructed.
The Yale-Brown Obsessive-Compulsive Scale can help with identification.
Exposure usually begins with the least anxiety-provoking situation. Some
therapists focus on the most anxiety producing situations first to achieve
more rapid progress. Which one is employed will depend on the therapist's
and the patient's ability or willingness to tolerate anxiety. One or two
obsessions and rituals should be worked with at a time to avoid overwhelming
the patient. The patient is assigned homework exercises. He or she may
need assistance with these assignments from family members or therapist
home visits. Participant modeling may be incorporated in exposure and
response prevention. The patient is asked to copy the therapist. I observe
my family and friends to help me determine "normal" behavior. When I am
not sure if my behavior is appropriate, I ask one of my support people.
Family
members should be asked to participate in the therapy. Role-playing under
the supervision of the therapist can help them understand homework assignments.
Keeping a diary serves as a reminder of progress. It also helps the therapist
identify areas of resistance.
In
some cases, patients experience OCD symptoms only in particular situations.
Exposure and response prevention may need to be carried out in special
settings. Home visits or field trips may be required by the therapist.
For best results, the therapist needs to be well trained in behavior therapy,
the patient must be highly motivated and faithful in fulfilling homework
assignments, and the patient's family needs to be cooperative.
Treatment
for primary obsessional slowness may involve prompting, pacing, and reminders
of the passage of time. Repeated exposure to disorder can also be used.
Patients with obsessions and few compulsions are more difficult to treat
with behavior therapy. OCD patients whose obsessive thoughts focus on
real-life problems may benefit from therapy used for chronic worriers.
The patient is instructed to refocus on the present moment when worrying
occurs. Worrying is postponed until a prescribed 30 minute worry period
each day. During this time the patient engages in formal problem solving.
Exposure in the form of writing out or saying the obsession aloud may
be helpful.
Behavior
therapy for hoarding involves encouraging the patient to gradually discard
items. The therapist will help the patient determine the order in which
things can be thrown out. Hoarders need guidelines for what to save and
discard. The therapist may need to visit the patient's home to get a clear
picture of the problem.
Cognitive
Therapy
Cognitive
therapy involves attempts to change distorted thinking and beliefs. There
is little controlled research evidence that cognitive therapy is effective
in the absence of behavior therapy. Most OCD patients have already spent
a large amount of time trying to correct their faulty thinking. They usually
are aware that their thinking is obsessive and abnormal. With this disclaimer,
it is my opinion that cognitive therapy is helpful, and it may be gaining
more acceptance. It helped me with my recovery.
Cognitive
therapy works best if the patient is intellectually able to understand
abstract thinking. The therapist helps the patient identify inaccurate
thoughts, and replace them with healthier ones. OCD patients tend to overestimate
risks. Cognitive therapy can attempt to challenge the patient's overestimation
of the probability of the feared catastrophe.
We
also tend to overestimate consequences. These false beliefs are also challenged.
Even a low probability of catastrophe can cause great anxiety in the OCD
patient, so the therapist may also concentrate on what makes the consequences
of feared events so unacceptable to the patient.
We
often have a poor tolerance of uncertainty. Knowing that a particular
negative event might happen is enough to cause anxiety. The therapist
may point out that routine behaviors that the patient regularly engages
in are more dangerous than the risk associated with the obsessional fear.
Many OCD patients participate in quite risky behavior unrelated to their
obsessions.
OCD
patients tend to have an inflated sense of responsibility. "If something
bad happens, it will be my fault." The therapist can help the patient
adapt a more realistic sense of his own responsibility.
Anxiety
and depression frequently interfere with the patient's ability to concentrate
on the therapist's instruction. Many patients do not know what beliefs
or appraisals are behind their obsessive thoughts and compulsive behaviors.
Cognitive therapy can be used to assist in behavior therapy. If the person
with OCD is reluctant to try behavior therapy, cognitive approaches can
be used to explore and address fears about the therapy.
Cognitive-Behavioral
Therapy
The
UCLA School of Medicine has been studying OCD for over 10 years. They
have developed a self-directed cognitive-behavioral therapy to supplement
exposure and response prevention.
Dr.
Jeffrey Schwartz has written a book, Brain Lock, that details this
therapy, which he calls the Four-Step Self-Treatment Method.
