OCD-Related Disorders

14 cases on OCD-spectrum pharmacotherapy — dosing philosophy, augmentation, body dysmorphic disorder, hoarding disorder, trichotillomania, and emerging treatment approaches — choose a case below to open its full multi-voice debate.

PsychiatryOCD-Related Disorders
SSRI Dosing in OCD: Why the Depression Target Dose Falls Short

A sertraline dose that would count as an adequate depression trial left his obsessions and compulsions essentially untouched — because OCD's own dose-response curve runs well past that ceiling.

Case 0001
PsychiatryOCD-Related Disorders
Clomipramine vs. SSRI as First-Line Therapy for OCD

Clomipramine's own meta-analytic numbers edge out the SSRIs for OCD specifically — the disagreement is whether that edge is worth its cardiac and anticholinergic price for a first medication trial.

Case 0002
PsychiatryOCD-Related Disorders
Augmentation Strategy in SSRI-Resistant OCD

Two adequate SSRI trials have failed him, and the three real next-step options — antipsychotic augmentation, adding clomipramine, or switching class again — have no guideline-ranked order to choose between.

Case 0003
PsychiatryOCD-Related Disorders
How Long an SSRI Trial in OCD Must Run Before Calling It a Failure

Six weeks of fluoxetine and no clear improvement looked like a failed trial to the covering resident — but OCD's own antiobsessional response window runs nearly twice that long.

Case 0004
PsychiatryOCD-Related Disorders
Deep Brain Stimulation for Severe, Treatment-Refractory OCD

Five adequate medication trials and three years out of work later, the real question isn't whether deep brain stimulation works — it's whether pharmacotherapy is actually exhausted enough to justify neurosurgery.

Case 0005
PsychiatryOCD-Related Disorders
Ketamine for Treatment-Resistant OCD

She has heard ketamine works fast for depression and wants to know why it isn't being offered for her OCD — the honest answer is that its OCD evidence is real but far thinner, and the benefit fades in days rather than weeks.

Case 0006
PsychiatryOCD-Related Disorders
Pediatric OCD Dosing Against the SSRI Black-Box Warning

Both teenagers carry the identical FDA black-box warning on the identical drug class — but the OCD patient's own diagnosis requires reaching a meaningfully higher dose to get there, sharpening a risk conversation the depression patient's case leaves comparatively familiar.

Case 0007
PsychiatryOCD-Related Disorders
SSRI Dosing in Body Dysmorphic Disorder

OCD's own high-dose SSRI philosophy is well established — the real question here is whether body dysmorphic disorder, a related but genuinely distinct diagnosis, actually needs the same ceiling or an even higher one.

Case 0008
PsychiatryOCD-Related Disorders
Distinguishing Body Dysmorphic Disorder from a Legitimate Cosmetic Concern

A plastic surgeon paused a rhinoplasty consultation over a feeling that something didn't add up — the real stakes of telling BDD apart from an ordinary cosmetic concern before, not after, an elective procedure.

Case 0009
PsychiatryOCD-Related Disorders
Pharmacotherapy for Hoarding Disorder: Does OCD's Evidence Actually Extrapolate?

Hoarding disorder shares OCD's DSM-5 chapter, but its own SSRI trials show a genuinely weaker and less consistent response — raising a real question about whether medication is worth trying at all, and for how long.

Case 0010
PsychiatryOCD-Related Disorders
N-Acetylcysteine for Trichotillomania

SSRIs have a genuinely disappointing track record in trichotillomania — N-acetylcysteine offers a distinct glutamate-based mechanism with real but mixed trial support, not a settled answer.

Case 0011
PsychiatryOCD-Related Disorders
SSRI Efficacy in Excoriation (Skin-Picking) Disorder

Excoriation disorder shares OCD's DSM-5 chapter and its first-line drug class, but not, it turns out, anything close to OCD's SSRI response rate — a genuine gap between shared classification and shared pharmacology.

Case 0012
PsychiatryOCD-Related Disorders
Memantine Augmentation in Treatment-Resistant OCD

Antipsychotic augmentation already failed her — memantine's distinct glutamatergic mechanism has real trial support in treatment-resistant OCD, but sits far behind antipsychotic augmentation in how often it's actually reached for.

Case 0013
PsychiatryOCD-Related Disorders
Psilocybin Research for OCD: A Much Earlier Stage Than Its Depression Trajectory

He read about psilocybin's Phase 3 depression trials and wants to know when the same option might reach his OCD — the honest answer is that OCD's psilocybin research sits at a genuinely much earlier, thinner stage.
