Are subarachnoid haemorrhages hereditary?

I know the actual haemorrhage isn't hereditary but my mother died of a subarachnoid haemorrhage and I was wondering if I am more likely to have one? She had high blood pressure and was a smoker and I have my b.p checked regularly and it's usually normal and I don't smoke.

Welcome to the ehealthforum. I am glad to help you out.

Mostly subarachnoid hemorrhage occurs due to rupture of an intracranial aneurysm and studies have indicated that smoking, hypertension, and alcohol misuse are important risk factors for subarachnoid haemorrhage due to aneurysms.

Genetic factors may also have a role and since your mother had it, you are advised to have an MRA scan to check for possible aneurysms.

It is very difficult to precisely confirm a diagnosis without examination and investigations, and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care.
