People with obsessive-compulsive disorder (OCD) have recurrent, unwanted thoughts, impulses or fears. They may worry that they're unclean, that they've left an appliance on, or that they will forget, lose or misplace something.
To combat these obsessions, people with OCD create rituals. The person may begin washing each time he or she feels unclean, repeatedly check that the appliance is turned off, rearrange items in a precise way or compulsively count the items.
Unfortunately, these rituals provide only temporary relief, driving the person to perform them over and over. In the most severe cases, the rituals become so consuming that the person has no time for a normal life. Each minute is spent satisfying the compulsion.
Most people with OCD know their thoughts and actions are inappropriate, but they can't stop the behaviors. This may cause shame and anxiety. Often, they attempt to ignore or suppress those troubling behaviors by substituting other thoughts or actions, according to the American Psychiatric Association.
Causes
Although no one knows for sure what causes this disorder, it may have a neurobiological cause. Researchers have determined that several parts of the brain are associated with fear and anxiety, according to the National Institute of Mental Health. OCD sometimes runs in families.
Treatments
Serotonin reuptake inhibitors (SRIs), including selective serotonin reuptake inhibitors (SSRIs), have been effective in treating this disorder in some people. If one drug isn't effective, another may work better.
Some people with OCD benefit from a therapy called exposure and response prevention, in which the person is exposed to whatever triggers the obsessive fears and is taught coping techniques to help avoid performing the rituals.
With proper treatment and family support, people with OCD can usually manage their symptoms.
