Sturge-Weber syndrome (SWS) is a rare, non-inherited neurocutaneous disorder caused by a random gene mutation. It is characterized by a facial "port-wine" birthmark, glaucoma, and abnormal blood vessels on the brain's surface (leptomeningeal angiomas). Key symptoms include seizures, developmental delays, and stroke-like episodes, with treatment focusing on managing symptoms through anti-seizure medication, glaucoma eye drops, and laser therapy.
