Treatment and management of obsessive-compulsive disorder — FAQ

This is a common misconception. OCD is a serious anxiety disorder, not a personality quirk. The 'O' (obsessions) are intrusive, distressing thoughts, not just worries about cleanliness. The 'C' (compulsions) are not voluntary choices but are performed to neutralise the intense anxiety from the obsessions. Telling someone to 'just stop' ignores the debilitating anxiety that drives the behaviour.

Not necessarily. The effectiveness of SSRIs provides strong support for the biological (serotonin hypothesis) explanation, but it doesn't rule out other factors. This is known as the 'treatment-aetiology fallacy' – assuming a treatment's success reveals the cause. Psychological therapies like CBT/ERP are also highly effective, suggesting cognitive and behavioural factors are equally crucial. OCD is best understood through a biopsychosocial model.

While ERP is intentionally challenging, it is considered a safe and highly effective treatment when conducted by a trained therapist. The process is collaborative and gradual, starting with less anxiety-provoking situations (a 'fear hierarchy'). The therapist supports the patient throughout, and the short-term distress is a necessary part of achieving long-term relief. The goal is to prove to the patient that they can manage the anxiety without rituals, which is ultimately empowering.
