Sinister Headache Type

Meningitis/Subarachnoid Haemorrhage/Cranial Arteritis. The main question is how can we recognise a sinister headache type! The major red flag is age. Three-quarters of migraine sufferers have had their first migraine by the age of 30 and it is increasingly less likely that the first attack be much above 30. Abrupt onset with vomiting is another warning. The patient should seek expert medical opinion.
