Fs obsessive-compulsive disorder (maech 08).pub
Obsessions are intrusive, irrational thoughts — unwanted ideas or impulses that
repeatedly come up in a person’s mind. Again and again, the person experiences
disturbing thoughts, such as “My hands must be contaminated; I must wash 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
Compulsions are repetitive rituals such as hand washing, counting, checking,
hoarding, or arranging. An individual repeats these actions, perhaps feeling momen-
tary 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
The National Institute of Mental Health estimates that more than 2% of the U.S.
population will suffer from OCD at some point in their lives.
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.
Response to treatment varies from person to person. Most people treated with
effective medications find their symptoms reduced by about 40 to 50%. That can
often be enough to change their lives, to transform them into functioning individuals.
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 peo-ple 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. OCD will not go away by itself, so it is important to seek treatment. OCD is a chronic disease. Fortunately, effective treatments are available that make life with OCD much easier to manage.
