Headache with Aura Harrison22E

Presentation · PPTX

12-slide focused presentation on Headache with Aura:

#	Slide	Highlights
1	Title	Dark navy + violet theme, real MRI backdrop
2	What is Migraine Aura?	8 defining features, ICHD-3 criteria, why only 20–25% of patients
3	Types of Aura	Visual, Sensory, Language, Motor (FHM) — full detail for each
4	Brainstem Aura & Retinal Migraine	Formerly "basilar migraine"; 9 brainstem symptoms; retinal migraine DDx
5	4 Phases of Migraine	Prodrome → Aura (highlighted) → Headache → Postdrome with timings
6	Cortical Spreading Depression	CSD mechanism, 3–5 mm/min wave, FHM gene mutations + brain diagram
7	Real Human Brain Scan — Premonitory	Full-slide PET scan (Fig 441-2A): hypothalamic activation before pain
8	Real Human Brain Scan — Acute Attack	Full-slide MRI (Fig 441-2C): pontine activation lateralised to pain side
9	Aura vs. TIA / Stroke / Seizure	Comparison table across 9 features — key clinical differentiator
10	Acephalgic Migraine & Special Situations	Aura without headache, persistent aura, stroke risk in aura patients
11	Treatment	Acute (triptans, gepants, ditans) + Preventive (CGRP mAbs, CCBs for FHM) + OCP warning
12	Key Takeaways	8 points + 3-scan patient brain montage

If you meant something else by "erroa" (errors, era, etc.) just let me know and I'll rebuild it!
