What OCD is

According to NIMH, OCD is a common, long-lasting disorder in which a person has uncontrollable, recurring thoughts (obsessions), engages in repetitive behaviors (compulsions), or both. Obsessions are repeated thoughts, urges, or mental images that cause anxiety. Compulsions are repetitive behaviors a person feels the urge to do in response to an obsessive thought.

Common obsessions and compulsions

ObsessionsCompulsions
Fear of germs or contaminationExcessive cleaning or handwashing
Unwanted forbidden or taboo thoughtsMental rituals, praying, or neutralizing thoughts
Fear of harming yourself or othersRepeatedly checking (locks, stove, safety)
Need for symmetry or perfect orderOrdering or arranging things “just right”
Doubts and need for certaintyRepeatedly seeking reassurance

How OCD is treated

NIMH notes that OCD is typically treated with psychotherapy, medication, or both. The main psychotherapy is a type of cognitive behavioral therapy called exposure and response prevention (ERP): gradually facing triggers while resisting the compulsion, so the anxiety learns to fade on its own. The International OCD Foundation describes ERP as the most effective form of therapy for OCD. Medication (usually serotonin reuptake inhibitors) is prescribed by a doctor or psychiatrist.

Finding the right therapist

Because ERP is a specialized skill, ask any therapist — online or in person — whether they have specific experience treating OCD with ERP. Online sessions can work well for ERP, since you can practice exposures in the real environments where your triggers happen, like your own home.
