The Obsessive Disorder

Worries, doubts, superstitious beliefs all are common in everyday life. However, when they become so excessive such as hours of hand washing or make no sense at all such as driving around and around the block to check that an accident didn't occur then a diagnosis of OCD is made. In OCD, it is as though the brain gets stuck on a particular thought or urge and just can't let go. People with OCD often say the symptoms feel like a case of mental hiccups that won't go away. OCD is a medical brain disorder that causes problems in information processing. It is not your fault or the result of a "weak" or unstable personality.

What are the symptoms of Obsessive-Compulsive Disorder?
Obsessions
Obsessions are thoughts, images, or impulses that occur over and over again and feel out of your control. The person does not want to have these ideas, finds them disturbing and intrusive, and usually recognises that they don't really make sense. People with OCD may worry excessively about dirt and germs and be obsessed with the idea that they are contaminated or may contaminate others. Or they may have obsessive fears of having inadvertently harmed someone else (perhaps while pulling the car out of the driveway), even though they usually know this is not realistic. Obsessions are accompanied by uncomfortable feelings, such as fear, disgust, doubt, or a sensation that things have to be done in a way that is "just so."

Compulsions
People with OCD typically try to make their obsessions go away by performing compulsions. Compulsions are acts the person performs over and over again, often according to certain "rules." People with an obsession about contamination may wash constantly to the point that their hands become raw and inflamed. A person may repeatedly check that she has turned off the stove or iron because of an obsessive fear of burning the house down. She may have to count certain objects over and over because of an obsession about losing them. Unlike compulsive drinking or gambling, OCD compulsions do not give the person pleasure. Rather, the rituals are performed to obtain relief from the discomfort caused by the obsessions.

Other features of Obsessive-Compulsive Disorder
*OCD symptoms cause distress, take up a lot of time (more than an hour a day), or significantly interfere with the person's work, social life, or relationships.
*Most individuals with OCD recognize at some point that their obsessions are coming from within their own minds and are not just excessive worries about real problems, and that the compulsions they perform are excessive or unreasonable. When someone with OCD does not recognise that their beliefs and actions are unreasonable, this is called OCD with poor insight.
*OCD symptoms tend to wax and wane over time. Some may be little more than background noise; others may produce extremely severe distress.

When does Obsessive-Compulsive Disorder begin?
OCD can start at any time from preschool age to adulthood (usually by age 40).

One third to one half of adults with OCD report that it started during childhood. Unfortunately, OCD often goes unrecognised.

Earlier diagnosis and proper treatment, including finding the right medications, can help people avoid the suffering associated with OCD and lessen the risk of developing other problems, such as depression or marital and work problems.

Is Obsessive-Compulsive Disorder Inherited?
No specific genes for OCD have yet been identified, but research suggests that genes do play a role in the development of the disorder in some cases. Childhood-onset OCD tends to run in families (sometimes in association with tic disorders). When a parent has OCD, there is a slightly increased risk that a child will develop OCD, although the risk is still low. When OCD runs in families, it is the general nature of OCD that seems to be inherited, not specific symptoms.

What causes Obsessive-Compulsive Disorder?
There is no single, proven cause of OCD. Research suggests that OCD involves problems in communication between the front part of the brain (the orbital cortex) and deeper structures (the basal ganglia).

These brain structures use the chemical messenger serotonin. It is believed that insufficient levels of serotonin are prominently involved in OCD. Drugs that increase the brain concentration of serotonin often help improve OCD symptoms.
