Headache ICHD3

Headache ICHD-3 Guide puts the International Classification of Headache Disorders (ICHD-3) in your pocket — every category, laid out for fast reference and built around a diagnostic criteria checker you can work through at the bedside. THE LIVE CRITERIA CHECKER Pick a diagnosis, tick the features your patient has, and the app works out in real time whether the ICHD-3 criteria are met. It handles the tricky group rules for you ("at least 2 of 4", "at least 3 of 6"), shows how many criteria are satisfied, and tells you exactly which ones are still outstanding. A verdict bar turns green the moment a diagnosis is complete. COMPLETE ICHD-3 COVERAGE • All 14 ICHD-3 categories — primary headaches, secondary headaches and the cranial neuralgias • The primary headaches in full: migraine (with and without aura, chronic, hemiplegic, status migrainosus and more), tension-type headache, the trigeminal autonomic cephalalgias (cluster, paroxysmal hemicrania, SUNCT/SUNA, hemicrania continua) and the other primary headache disorders • The high-yield secondary red flags: subarachnoid haemorrhage, giant cell arteritis, RCVS, idiopathic intracranial hypertension, low-CSF-pressure headache, medication-overuse headache and more • The cranial neuralgias: trigeminal, glossopharyngeal and occipital neuralgia CLINICAL NOTES FOR EVERY DISORDER Each entry carries concise, scannable clinical notes — epidemiology, provoking factors, red-flag pointers and management cues — distilled for rapid recall. BUILT FOR THE WARD • Beautiful light and dark themes • Adjustable text size • Fast search by name, code or symptom • Colour-coded so primary, secondary and neuralgia disorders are instantly distinguishable • Fully offline — everything is on your device, no account and no internet needed A ONE-TIME PURCHASE No subscriptions.

FOR CLINICIANS AND TRAINEES Designed for neurologists, acute and general physicians, GPs, emergency clinicians, and anyone preparing for postgraduate exams (including the MRCP SCE in Neurology) who wants the ICHD-3 criteria at their fingertips. — Educational and training use only. This app reproduces ICHD-3 diagnostic criteria as a study and decision-support aid. It is not a substitute for clinical judgement and must not be used as the sole basis for diagnosis or treatment.
