OCD may cause:
Obsessions—unwanted, repetitive, and intrusive ideas, impulses, or images; common obsessions include:
- Persistent fears that harm may come to self or a loved one
- Unreasonable concern with being contaminated
- Unreasonable concerns about safety
- Unacceptable religious, violent, or sexual thoughts
- Excessive need to do things correctly or perfectly
- Persistent worries about a tragic event
Compulsions—repetitive behaviors or mental acts to reduce the distress associated with obsessions; common compulsions include:
- Excessive checking of door locks, stoves, water faucets, and light switches
- Repeatedly making lists, counting, arranging, or aligning things
- Collecting and hoarding useless objects
- Repeating routine actions a certain number of times until it feels right
- Unnecessary rereading and rewriting
- Mentally repeating phrases
- Repeatedly washing hands
Conditions associated with OCD include:
- Other anxiety disorders
- Organic brain syndrome
- Tourette syndrome
- Attention deficit disorder
If you have OCD, you may know that your thoughts and compulsions do not make sense, but you are unable to stop them.
Treatment reduces OCD thoughts and compulsions, but does not completely eliminate them. Common treatment approaches include a combination of medication and therapy.
Selective serotonin reuptake inhibitors (SSRIs) reduce OCD symptoms by affecting serotonin levels. Tricyclic antidepressants can also help treat symptoms.
Your doctor may try using other psychiatric medications to help control your condition.
Behavioral therapy addresses the actions associated with OCD. Cognitive-behavioral therapy (CBT) addresses both the thought processes and the actions associated with OCD.
Treatment of OCD is tailored to meet your particular needs.
Examples of therapies used to treat OCD include:
- Exposure and response prevention—involves gradually confronting the problem object or obsession without giving into the compulsive ritual linked to it
- Aversion therapy—involves using a painful stimulus to prevent OCD behavior
- Thought switching—involves learning to replace negative thoughts with positive thoughts
- Flooding—involves being exposed to an object that causes OCD behavior
- Implosion therapy—involves being repeatedly exposed to an object that causes fear
- Thought stopping—involves learning how to stop negative thoughts
Electroconvulsive therapy (ECT) has had some success for those with OCD that is difficult to treat. However, the treatment is not for everyone. Be sure to discuss the benefits and harms of ECT treatment with your doctor.
