Obsessive Compulsive
Disorder
OCD is one of the better-known
mental illnesses. Cases of excessive hand-washing or hoarding are
the best known, but OCD can manifest itself in less-obvious ways.
In my case, it is a two-line prayer that I can't stop repeating in my head.
I'm now on Welbutrin, which helps me keep it under control most of the
time. The NAMI (National Alliance
for the Mentally Ill)
fact sheet on OCD is below.
-
A woman visits her dermatologist,
complaining of extremely dry skin and seldom feeling clean. She showers
for two hours every day.
-
A lawyer insists on making coffee
several times each day. His colleagues do not realize that he lives in
fear that the coffee will be poisoned, and he feels compelled to pour most
of it down the drain. The lawyer is so obsessed with these thoughts that
he spends 12 hours a day at work -- four of them worrying about contaminated
coffee.
-
A man cannot bear to throw anything
away. Junk mail, old newspapers, empty milk cartons all "could contain
something valuable that might be useful someday." If he throws things away,
"something terrible will happen." He hoards so much clutter that he can
no longer walk through his house. Insisting that nothing be thrown away,
he moves to another house where he continues to hoard.
These people suffer obsessive-compulsive
disorder (OCD). The National Institute of Mental Health estimates that
more than 2 percent of the U.S. population, or nearly one out of every
40 people, will suffer from OCD at some point in their lives. The disorder
is two to three times more common than schizophrenia and bipolar disorder.
What is Obsessive-compulsive disorder?
Obsessions are intrusive, irrational
thoughts -- unwanted ideas or impulses that repeatedly well up in a person's
mind. Again and again, the person experiences disturbing thoughts, such
as "My hands must be contaminated; I must was them"; "I may have left the
gas stove on"; "I am going to injure my child." On one level, the sufferer
knows these obsessive thoughts are irrational. But on another level, he
or she fears these thoughts might be true. Trying to avoid such thoughts
creates great anxiety.
Compulsions are repetitive rituals
such as handwashing, counting, checking, hoarding, or arranging. An individual
repeats these actions, perhaps feeling momentary relief, but without feeling
satisfaction or a sense of completion. People with OCD feel they must perform
these compulsive rituals or something bad will happen.
Most people at one time or another
experience obsessive thoughts or compulsive behaviors. Obsessive-compulsive
disorder occurs when an individual experiences obsessions and compulsions
for more than an hour each day, in a way that interferes with his or her
life.
OCD is often described as "a disease
of doubt." Sufferers experience "pathological doubt" because they are unable
to distinguish between what is possible, what is probable, and what is
unlikely to happen.
Who gets OCD?
People from all walks of life
can get OCD. It strikes people of all social and ethnic groups and both
males and females. Symptoms typically begin during the teenage years or
young adulthood.
What causes OCD?
A large body of scientific evidence
suggests that OCD results from a chemical imbalance in the brain. For years,
mental health professionals incorrectly assumed OCD resulted from pad parenting
or personality defects. This theory has been disproven over the last 20
years. OCD symptoms are not relieved by psychoanalysis or other forms of
"talk therapy," but there is evidence that behavior therapy can be effective,
alone or in combination with medication. People with OCD can often say
"why" they have obsessive thoughts or why they behave compulsively. But
the thoughts and the behavior continue.
People whose brains are injured
sometimes develop OCD, which suggests it is a physical condition. If a
placebo is given to people who are depressed or who experience panic attacks,
40 percent will say they feel better. If a placebo is given to people who
experience obsessive-compulsive disorder, only about two percent say they
feel better. This also suggests a physical condition.
Clinical researchers have implicated
certain brain regions in OCD. They have discovered a strong link between
OCD and a brain chemical called serotonin. Serotonin is a neurotransmitter
that helps nerve cells communicate.
Scientists have also observed
that people with OCD have increased metabolism in the basal ganglia and
the frontal lobes of the brain. This, scientists believe, causes repetitive
movements, rigid thinking, and lack of spontaneity. People with OCD often
have high levels of the hormone vasopressin.
In layperson's terms, something
in the brain is stuck, like a broken record. Judith Rapoport, M.D., describes
it in her book, The Boy Who Couldn't Stop Washing, as "grooming behaviors
gone wild."
How do people with OCD typically
react to their disorder?
People with OCD generally attempt
to hide their problem rather than seek help. Often they are remarkably
successful in concealing their obsessive-compulsive symptoms from friends
and co-workers. An unfortunate consequence of this secrecy is that people
with OCD generally do not receive professional help until years after the
onset of their disease. By that time, the obsessive-compulsive rituals
may be deeply ingrained and very difficult to change.
How long does OCD last?
OCD will not go away by itself,
so it is important to seek treatment. Although symptoms may become less
severe from time to time, OCD is a chronic disease. Fortunately, effective
treatments are available that make life with OCD much easier to manage.
Is age a factor in OCD?
OCD usually starts at an early
age, often before adolescence. It may be mistaken at first for autism,
pervasive developmental disorder, or Tourette's syndrome, a disorder that
may include obsessive doubting and compulsive touching as symptoms.
Like depression, OCD tends to
worsen as the person grows older, if left untreated. Scientists hope, however,
that when the OCD is treated while the person is still young, the symptoms
will not get worse with time.
What are other examples of behaviors
typical of people who suffer from OCD?
People who do the following may
have OCD:
-
repeatedly check things, perhaps
dozens of times, before feeling secure enough to go to sleep or leave the
house. Is the stove off? Is the door locked? Is the alarm set?
-
fear they will harm others. Example:
A man's car hits a pothole on a city street and he fears it was actually
a body.
-
feel dirty and contaminated. Example:
A woman is fearful of touching her baby because she might contaminate the
child.
-
constantly arrange and order things.
Example: A child can't go to sleep unless he lines up all his shoes correctly.
-
are excessively concerned with
body imperfections -- insist on numerous plastic surgeries, or spend many,
many hours a day body-building.
-
are ruled by numbers, believing
that certain numbers represent good and others represent evil.
-
are excessively concerned with
sin or blasphemy.
Is OCD commonly recognized by professionals?
Not nearly commonly enough. OCD
is often misdiagnosed, and it is often underdiagnosed. Many people have
dual disorders of OCD and schizophrenia, or OCD and bipolar disorder, but
the OCD component is not diagnosed or treated. Researchers believe OCD,
anxiety disorders, Tourette's, and eating disorders such as anorexia and
bulimia can be triggered by some of the same chemical malfunctioning of
the brain.
Is heredity a factor in OCD?
Yes. Heredity appears to be a
strong factor. If you have OCD, there's a 25-percent chance that one of
your immediate family members will have it. It definitely seems to run
in families.
Can OCD be effectively treated?
Yes, with medication and behavior
therapy. Both affect brain chemistry, which in turn affects behavior. Medication
can regulate serotonin, reducing obsessive thoughts and compulsive behaviors.
Anafranil (clomipramine):
A tricyclic antidepressant, Anafranil has been shown to be effective in
treating obsessions and compulsions. The most commonly reported side effects
of this medication are dry mouth, constipation, nausea, increased appetite,
weight gain, sleepiness, fatigue, tremor, dizziness, nervousness, sweating,
visual changes, and sexual dysfunction. There is also a risk of seizures,
thought to be dose-related. People with a history of seizures should not
take this medication. Anafranil should also not be taken at the same time
as a monoamine oxidase inhibitor (MAOI).
Many of the antidepressant medications
known as selective serotonin reuptake inhibitors (SSRIs) have also proven
effective in treating the symptoms associated with OCD. The SSRIs most
commonly prescribed for OCD are Luvox (fluvoxamine), Paxil (paroxetine),
Prozac (fluoxetine), and Zoloft (sertraline).
Luvox (fluvoxamine): Common
side effects of this medication include dry mouth, constipation, nausea,
sleepiness, insomnia, nervousness, dizziness, headache, agitation, weakness,
and delayed ejaculation.
Paxil (paroxetine): Side
effects most associated with this medication include dry mouth, constipation,
nausea, decreased appetite, sleepiness, insomnia, tremor, dizziness, nervousness,
weakness, sweating, and sexual dysfunction.
Prozac (fluoxetine): Dry
mouth, nausea, diarrhea, sleepiness, insomnia, tremor, nervousness, headache,
weakness, sweating, rash, and sexual dysfunction are among the more common
side effects associated with this drug.
Zoloft (sertraline): Among
the side effects most commonly reported while taking Zoloft are dry mouth,
nausea, diarrhea, constipation, sleepiness, insomnia, tremor, dizziness,
agitation, sweating, and sexual dysfunction.
SSRIs should never be taken at
the same time as MAOIs.
How long should an individual take
medication before judging its effectiveness?
Some physicians make the mistake
of prescribing a medication for only three or four weeks. That really isn't
long enough. Medication should be tried consistently for 10 to 12 weeks
before its effectiveness can be judged.
What is behavior therapy, and can
it effectively relieve symptoms of OCD?
Behavior therapy is not traditional
psychotherapy. It is "exposure and response prevention," and it is effective
for many people with OCD. Consumers are deliberately exposed to a feared
object or idea, either directly or by imagination, and are then discouraged
or prevented from carrying out the usual compulsive response. For example,
a compulsive hand-washer may be urged to touch an object he or she believes
is contaminated and denied the opportunity to wash for several hours. When
the treatment works well, the consumer gradually experiences less anxiety
from the obsessive thoughts and becomes able to refrain from the compulsive
actions for extended periods of time.
Several studies suggest that medication
and behavior therapy are equally effective in alleviating symptoms of OCD.
About half of the consumers with this disorder improve substantially with
behavior therapy; the rest improve moderately.
Will OCD symptoms go away completely
with medication and behavior therapy?
Response to treatment varies from
person to person. Most people treated with effective medications find their
symptoms reduced by about 40 percent to 50 percent. That can often be enough
to change their lives, to transform them into functioning individuals.
A few consumers find that neither
treatment produces significant change, and a small number of people are
fortunate to go into total remission when treated with effective medication
and/or behavior therapy.
