Will OCD Ever Go Away?

OCD doesn’t usually go away the way a cold does, but it can loosen its grip so much that it stops running your life. The question underneath is often whether you’ll ever be free of it. In my practice, many people get there, and long-term research shows many people improve, though OCD often lasts for years.

The short answer

  • Over 40 years: In a 40-year follow-up of people hospitalized for OCD, 83% had improved and 48% had recovered, though only 20% had recovered completely (Skoog & Skoog, 1999).
  • Long courses are common: In the same 40-year study, 48% of people had OCD for more than 30 years (Skoog & Skoog, 1999).
  • Childhood OCD: OCD that began in childhood or adolescence persisted in 41% of young people at follow-up, and a longer illness before assessment predicted persistence (Micali, 2010).
  • After treatment stops: Twelve weeks after treatment ended, 12% of people who had responded to ERP relapsed, compared with 45% of those who had responded to clomipramine alone (Simpson, 2004).
  • ERP has the largest trial base: A meta-analysis of 37 randomized trials found large effects for CBT including ERP compared with waitlist and placebo (Öst, 2015).

What happens to OCD without treatment?

Without treatment, OCD often lasts a long time, though many people improve over the decades. The 40-year study above followed people whose OCD was severe enough to need a hospital stay, and most improved, though only one in five recovered completely. In young people, a longer illness before assessment predicted that OCD would persist.

In my practice, waiting it out mostly means the rituals get more practice, and practised rituals feel more automatic. If OCD is affecting your work or school, whether OCD counts as a disability covers accommodations.

What does recovery from OCD actually look like?

Recovery looks like no longer needing to answer the intrusive thought, rather than never having one. Everyone has intrusive thoughts, people with OCD and people without. The thought can show up, and instead of an hour of checking or reassurance, you let it be there. As I put it in session: “Realistic improvement is just like: yeah, you know what, I don’t really like that thought, but I’m not going to run away from it. Nor am I going to do a bunch of things to make sure that thought doesn’t come back.”

When OCD runs your lifeWhen it has loosened its grip
An intrusive thoughtFeels like an emergency that needs an answerStill shows up, and doesn’t need an answer
RitualsCan take hours out of a dayRare, and you can catch them
AvoidanceYour world shrinks around the triggersYou go where you want to go
A flareFeels like starting overA cue to use the skills

For the harder version of this question, see whether you can 100% recover from OCD.

Does ERP make OCD go away for good?

ERP doesn’t promise that OCD never returns, but it teaches skills you keep, and in one trial its gains held better than medication alone after treatment stopped. Exposure and Response Prevention (ERP) works by helping you face the trigger while dropping the compulsion, so you learn that what OCD predicted doesn’t happen, or that you can carry the uncertainty without the ritual. That’s called expectancy violation.

I won’t promise a cure, and you should be cautious of anyone who does. OCD can flare in stressful periods, and the same tools that got you better are the ones you use on a flare. That is what relapse prevention is for. Some people also use medication for OCD, for a period or longer term. The client stories, all composites, show what this work looks like.

Frequently asked questions

Can OCD go away on its own?

Long-term studies show many people improve over time, but long courses are common: in a 40-year follow-up, 48% had OCD for more than 30 years (Skoog & Skoog, 1999). Waiting also gives the rituals more practice.

Does OCD come back after treatment?

It can flare, especially during stressful periods. In one trial, 12 weeks after treatment ended, 12% of people who had responded to ERP relapsed, compared with 45% after clomipramine alone (Simpson, 2004). A flare is a cue to use the skills again.

Will I still have intrusive thoughts after treatment?

Intrusive thoughts are common across countries and cultures (Pascual-Vera, 2019), so treatment doesn’t aim to remove them. It aims to change what you do when one shows up.

Where can you go deeper?

If you're experiencing these symptoms, evidence-based treatment can help. We treat OCD, and only OCD, with Exposure and Response Prevention (ERP).

How we researched this page

This page draws on a 40-year follow-up by Skoog and Skoog (1999), a follow-up of 142 children and adolescents by Micali and colleagues (2010), a trial of relapse after stopping treatment (Simpson et al., 2004), a meta-analysis of 37 randomized trials (Öst et al., 2015) and a cross-cultural study of intrusive thoughts (Pascual-Vera et al., 2019), alongside what I see in my practice. Skoog’s patients had OCD severe enough to be hospitalized, Micali’s came from one pediatric clinic, and Simpson measured relapse only 12 weeks after treatment ended, so none of these figures can tell you how OCD will go for you. The picture of recovery in the table is clinical observation.

A note on my perspective

I run a private clinic that treats OCD with ERP, and I'm paid when people book with us. Read what I write with that in mind. Public and lower-cost routes exist too, and the Ontario OCD treatment guide lays them out next to ours.
