(OCD)En Español (Spanish Version)More InDepth Information on This Condition
Obsessive-compulsive disorder (OCD) is an anxiety disorder. The person suffers from unwanted repetitive thoughts and behaviors. These obsessive thoughts and compulsive behaviors are very difficult to overcome. If severe and untreated, OCD can destroy the ability to function at work, school, or home.

The cause is unknown. OCD might be due to neurobiological, environmental, and psychological factors. An imbalance of serotonin (a brain chemical) may play a major role.
OCD is linked to other neurological disorders, including:
A risk factor is something that increases your chance of getting a disease or condition. Risk factors include:
- Obsessions—unwanted, repetitive, and intrusive ideas, impulses, or images
- Compulsions—repetitive behaviors or mental acts to reduce the distress associated with obsessions
People with OCD may know that their thoughts and behaviors do not make sense. And they would like to avoid or stop them. But they are often unable to block their obsessive thoughts or compulsions.
- Persistent fears that harm may come to self or a loved one
- Unreasonable concern with being contaminated
- Unacceptable religious, violent, or sexual thoughts
- Excessive need to do things correctly or perfectly
- Excessive checking of door locks, stoves, water faucets, light switches, etc.
- Repeatedly making lists, counting, arranging, or aligning things
- Collecting and hoarding useless objects
- Repeating routine actions a certain number of times until it feels just right
- Unnecessary rereading and rewriting
- Mentally repeating phrases
- Repeatedly washing hands
OCD is usually diagnosed through a psychiatric assessment. OCD is diagnosed when obsessions and/or compulsions either:
- Cause a person significant distress
- Interfere with a person’s ability to properly perform at work, school, or in relationships
Treatment reduces OCD thoughts and behaviors. But treatment does not completely eliminate them.
Selective serotonin reuptake inhibitors (SSRIs) reduce OCD symptoms by affecting the neurotransmitter serotonin. This function is independent of their antidepressant effects. SSRIs include:
- Fluoxetine (Prozac)
- Fluvoxamine (Luvox)
- Paroxetine (Paxil)
- Sertraline (Zoloft)
Please Note: On March 22, 2004, the Food and Drug Administration (FDA) issued a Public Health Advisory that cautions physicians, patients, families, and caregivers of patients with depression to closely monitor both adults and children receiving certain antidepressant medications. The FDA is concerned about the possibility of worsening depression and/or the emergence of suicidal thoughts, especially among children and adolescents at the beginning of treatment, or when there’s an increase or decrease in the dose. The medications of concern, mostly SSRIs (selective serotonin re-uptake inhibitors), are: Prozac (fluoxetine), Zoloft (sertraline), Paxil (paroxetine), Luvox (fluvoxamine), Celexa (citalopram), Lexapro (escitalopram), Wellbutrin (bupropion), Effexor (venlafaxine), Serzone (nefazodone), and Remeron (mirtazapine). Of these, only Prozac (fluoxetine) is approved for use in children and adolescents for the treatment of major depressive disorder. Prozac (fluoxetine), Zoloft (sertraline), and Luvox (fluvoxamine) are approved for use in children and adolescents for the treatment of obsessive compulsive disorder.

Another medication used is clomipramine (Anafranil). This is a tricyclic antidepressant drug that alters serotonin levels.
Behavior Therapy (Exposure and Response Prevention)
This helps you gradually confront the feared object or obsession without giving in to the compulsive ritual linked to it.
