Why OCD Becomes Difficult to Treat | Dr. Pavan Sonar Mumbai

OCD is highly treatable — Exposure and Response Prevention (ERP) therapy and SSRI medications have robust evidence for producing significant improvement in most patients. Yet a substantial proportion of people with OCD in Mumbai — perhaps 40–60% — do not achieve adequate improvement with first-line treatments, or relapse after initial improvement. Understanding why OCD becomes difficult to treat is the first step to finding more effective approaches. Dr. Pavan Sonar, an OCD specialist and psychiatrist in Mumbai, explains the factors that complicate OCD treatment and what can be done about them.

Factor 1: Delayed Diagnosis and Long Duration of Untreated OCD

The longer OCD is untreated, the more entrenched compulsive patterns become — neurologically and behaviourally. Early treatment produces faster and more complete recovery. In Mumbai, where OCD is frequently misdiagnosed (as anxiety, depression, or personality issues) or dismissed as “just habits,” patients may present for specialist treatment after 10–20 years of established OCD patterns. These long-standing patterns require more intensive ERP work and longer treatment courses than early-presenting OCD.

Factor 2: ERP Avoidance — The Most Common Reason for Treatment Failure

ERP therapy is effective only when conducted properly and consistently. The most common reason for ERP failure is insufficient exposure — patients, understandably frightened of the anxiety ERP intentionally produces, avoid fully engaging with exposures or engage superficially without genuine response prevention. ERP requires both adequate exposure intensity and full prevention of the associated compulsion. Partial engagement produces partial results. Accessing an experienced ERP therapist — who can calibrate exposures accurately and maintain therapeutic momentum — is crucial.

Factor 3: Comorbid Conditions Maintaining OCD

Co-occurring conditions significantly complicate OCD treatment: severe depression reduces motivation for ERP; ADHD impairs the sustained attention and commitment ERP requires; OCPD (Obsessive-Compulsive Personality Disorder) represents a fundamentally different treatment challenge that is not adequately addressed by standard OCD protocols; and bipolar disorder requires mood stabilisation before effective OCD treatment is possible. Accurate diagnosis of all co-occurring conditions — and treatment that addresses them appropriately — is essential for treatment-resistant OCD.

Factor 4: Inadequate Medication Dosing

OCD requires higher SSRI doses than depression — doses that many non-specialist prescribers do not reach. A patient prescribed the standard antidepressant dose of sertraline or fluoxetine for OCD may be significantly under-treated. Dr. Sonar carefully titrates SSRI dosing to therapeutic levels for OCD — typically higher than depression treatment — while monitoring tolerability. For non-responders, augmentation with low-dose antipsychotics (risperidone, aripiprazole) has strong evidence in treatment-resistant OCD.

Advanced Options for Treatment-Resistant OCD in Mumbai

For truly treatment-resistant OCD — after multiple adequate SSRI trials and intensive ERP with qualified therapists — advanced options include: SSRI augmentation with antipsychotics; intensive daily ERP programmes; and in the most severe cases, referral for TMS (Transcranial Magnetic Stimulation) or Deep Brain Stimulation (DBS) through specialist centres. Dr. Sonar coordinates referrals for appropriate cases.

Frequently Asked Questions

I’ve tried treatment before and it didn’t work. Should I try again?

Yes. Previous treatment failure often reflects inadequate dosing, insufficient ERP intensity, unaddressed comorbidities, or inexperienced therapists rather than a fundamental inability to improve. A thorough specialist reassessment can identify what was missing and guide a more effective second approach. Do not give up — treatment-resistant OCD can still improve significantly with the right approach.
