What OCD is

OCD has two parts. Obsessions are unwanted thoughts, images, or urges that keep coming back and cause real distress. Compulsions are the things you do, or do in your head, to get rid of that distress or to prevent something terrible from happening. The relief does not last, so the cycle repeats. Diagnostically, the cycle has to take up a lot of time (about an hour a day or more) or get in the way of your life.

It is more common than most people think. In a national survey, about 2.3% of US adults had OCD at some point in their lives, and about 1.2% in the past year (Ruscio et al., 2010). It usually starts in adolescence or early adulthood, and it can begin after a major life change such as pregnancy or childbirth.

It is not about being neat

The popular picture of OCD is handwashing and tidy desks, but it is often much more then being “neat.” Other examples I see often:

• Contamination: fear of germs, illness, or feeling dirty, with washing or avoiding to match

• Harm and checking: fear of causing an accident, leaving the stove on, or hurting someone, followed by checking again and again

• Unacceptable thoughts: violent, sexual, or blasphemous thoughts that horrify you, sometimes called taboo thoughts

• Relationship and identity doubts: needing certainty about whether you truly love your partner, or about your sexuality or morality

• Symmetry and “just right” feelings: repeating or arranging until it feels correct

• Mental rituals: reviewing conversations, praying or counting in a set way, silently cancelling a bad thought with a good one

Many compulsions are invisible. Reassurance-seeking, mental reviewing, and avoidance can go on for years without anyone, including you, calling it OCD.

The thoughts are not a warning

People with OCD are often tormented by thoughts that are the opposite of who they are. A gentle person has images of hurting someone. A devoted parent fears harming their child. A person with strong values is flooded with thoughts that disgust them. Having these thoughts does not mean you want to act on them. In OCD the thoughts are unwanted and frightening, and the response is to try to protect against them. That is a very different thing from an urge to cause harm. These thoughts are a recognized symptom and they respond to treatment.

Why it gets missed

Shame keeps people quiet, especially when the thoughts feel taboo. Rituals can be hidden, and mental ones can be invisible. In high-achieving people, checking and over-preparing get praised as conscientiousness. OCD is also often mistaken for generalized anxiety, depression, or perfectionism. A person can spend years in treatment for the wrong thing.

How we evaluate OCD

I ask specifically about obsessions and compulsions, including the mental ones and the avoidance, because people rarely volunteer them. I use a structured interview and the Y-BOCS, a standard rating of how severe symptoms are, so we have a baseline to measure progress against. I also look at what travels with OCD or looks like it: depression, GAD, tics, ADHD, autism, eating disorders, and substance use. In adolescents, a sudden, dramatic onset deserves a medical look as well.

As with anxiety, the details matter. Worry in GAD is usually about real-life problems and plays out as thinking. OCD tends to involve thoughts that feel irrational even to you, paired with rituals that you feel driven to perform.

Treatment

The American Psychiatric Association’s practice guideline recommends cognitive behavioral therapy with exposure and response prevention (ERP), and SSRI medication, as first-line treatments (Koran et al., 2007).

ERP. This is the treatment with the strongest track record. You work, step by step and at a pace you agree to, on facing the things that trigger your obsessions without performing the compulsion, until the fear fades on its own. In a landmark randomized trial, ERP outperformed both clomipramine and placebo, and adding clomipramine did not improve on ERP alone (Foa et al., 2005). ERP is a specialized skill, and a therapist trained in it makes a real difference. I will help you find one and coordinate with them.

Medication. SSRIs help many people with OCD, but the approach differs from depression: doses are often higher, and it can take eight to twelve weeks to judge whether a medication is working. Clomipramine is another option. If you have a partial response, adding a low dose of a second medication, such as aripiprazole or risperidone, can help. Benzodiazepines do not treat OCD. For people who do not improve after adequate trials, transcranial magnetic stimulation (TMS) has FDA clearance for OCD, and we can discuss whether it fits.

Family. Loved ones often get drawn into rituals without realizing it, answering the same reassurance question for the fifth time or changing routines to avoid a trigger. That is natural and kind, but it keeps OCD going. I am glad to include family members when it helps.

Most people improve a great deal with treatment. A realistic goal is that OCD stops running your day, and the thoughts lose their grip, even if they do not vanish.
