Epidemiology, diagnosis, and assessment on non-traumatic subarachnoid haemorrhage
Keyword(s):
Non-traumatic subarachnoid haemorrhage (ntSAH) is a neurological emergency. Clinical presentation is usually with severe headache, with or without abnormal neurological signs on clinical examination. NtSAH affects both males and females from 30 to 70 years, and the incidence increases with age. The incidence varies widely around the world. The gender distribution also varies in different countries, although overall the incidence is higher in women than in men. The commonest cause is rupture of an intracranial aneurysm, accounting for around 80% of cases. Diagnosis is usually by finding blood in the classical subarachnoid distribution on a cranial computed tomography scan. A number of grading systems are used to classify ntSAH.
