“Brain attack”Trigger – Dorsal ponsProdrome - HypothalmusAura – Cerebral cortexPeripheral sensitisation – Cranial vasculatureCentral sensitisation – ThalamusNausea/vomiting- Area Postrema Autonomic symptoms – Parasympathetic

systemNeck pain – Sensitisation of C2/C3

Why me?Blame your parentsChemical imbalanceYour brain is differentSymptoms between attacks
