## What is Differential DX Assistant?

IMPORTANT MEDICAL DISCLAIMER: This app provides educational information only. It does not provide medical advice, diagnosis, or treatment, and it is not a diagnostic device. Always seek the advice of a doctor, physician, licensed mental health professional, or other qualified health provider in addition to using this app, and before making any medical decisions. Do not rely on this app to make any medical, diagnostic, or treatment decision. Never disregard professional medical advice or delay seeking it because of information in this app. In an emergency, call 911 or contact the 988 Suicide & Crisis Lifeline.

A structured study companion for building differential diagnosis skills — without the guesswork of loose notes or scattered flashcards.

Designed for residents, psychiatry and psychology trainees, and social work and counseling students, this app turns symptom review into a guided clinical reasoning exercise. Select from roughly 67 presenting symptoms, rate severity as mild, moderate, or severe, and add clinical context like duration, onset, and functional impairment.

From there, explore ranked differential considerations across 33 disorders, informed by DSM-5-TR criteria, with a clear breakdown of how well each case matches diagnostic criteria. Every disorder displays ICD-10-CM codes alongside legacy DSM codes, so you can practice thinking the way real clinical documentation works.

NARROW THE DIFFERENTIAL
When several diagnoses remain in contention, a guided decision tree asks one targeted question at a time — each encoding a published DSM-5-TR exclusion criterion, required course, or hallmark feature. Considerations are ruled out or move up as you answer, with a teaching note explaining why each question matters, and ruled-out disorders stay listed with the reason recorded.

CHILDHOOD & ADOLESCENT COVERAGE
ADHD, Autism Spectrum Disorder, Oppositional Defiant Disorder, Conduct Disorder, Disruptive Mood Dysregulation Disorder, Separation Anxiety Disorder, Selective Mutism, Reactive Attachment Disorder, Tourette's Disorder, Language Disorder, and Intellectual Disability — with the age-of-onset, course, and severity questions that separate them.

EVERY SOURCE IS CITED
All clinical content is cited to public, authoritative sources — the DSM-5-TR (American Psychiatric Association), ICD-10-CM (CDC/NCHS), CMS official coding guidelines, WHO ICD-11, the National Institute of Mental Health, NIDA, NIAAA, MedlinePlus, and NCBI Bookshelf. A built-in Sources & References screen links directly to each one, and every disorder screen lists the specific sources behind its content.

Sharpen your skills with 9 practice case vignettes spanning beginner, intermediate, and advanced difficulty. Commit to a diagnosis, then review teaching points that reinforce key distinguishing features — ideal for exam prep, supervision discussions, or independent study.

Save your case sessions for later review, and export text summaries through the iOS share sheet for study groups, journals, or supervision notes.

Privacy is built in from the ground up: everything runs 100% on-device, with no account, no network requirement, and no analytics tracking your activity. Your practice cases stay yours.

This is a study aid for building clinical reasoning skills — not a diagnostic device, and not a reproduction of the DSM manual. Diagnostic criteria are paraphrased in summary form for educational purposes; consult the DSM-5-TR for authoritative wording, specifiers, and exclusion rules. DSM-5 and DSM-5-TR are trademarks of the American Psychiatric Association. This is an independent educational product and is not affiliated with or endorsed by the American Psychiatric Association.

Whether you're prepping for boards, working through case conceptualization, or building diagnostic confidence early in your career, this app gives you a private, structured space to practice.


## Version history (last 2 releases)

### 1.2.0 — 2026-09-05

NARROW THE DIFFERENTIAL
When more than one diagnosis remains in contention, a new guided decision tree asks one targeted question at a time. Each question encodes a published DSM-5-TR exclusion criterion, required course, or hallmark feature — history of mania, Criterion A trauma exposure, psychosis independent of mood episodes, age of onset, and more. The question order adapts to your case, so you are only asked what is relevant.

As you answer, considerations are ruled out or move up the list, and every question includes a teaching note explaining why it matters clinically. Nothing disappears silently: ruled-out disorders stay in a separate section with the reason recorded, and you can undo any answer or skip with "Not sure."

CHILDHOOD & ADOLESCENT DISORDERS
Eight new disorders join ADHD, Autism Spectrum Disorder, and Oppositional Defiant Disorder:
• Conduct Disorder
• Disruptive Mood Dysregulation Disorder
• Separation Anxiety Disorder
• Selective Mutism
• Reactive Attachment Disorder
• Tourette's Disorder
• Language Disorder
• Intellectual Disability

Each includes ICD-10-CM codes and the discriminating questions that separate them — ODD versus Conduct Disorder severity, DMDD versus episodic bipolar mood, selective mutism versus autism, and attachment disorder versus autism.

Also in this release: 33 disorders and roughly 67 symptoms total, refinement notes on each result card, and exported case summaries now include your differentiating questions and any ruled-out considerations for supervision.

### 1.1.0 — 2026-08-28
