subarachnoid haenorrhage

A friend of mine had a subarachnoid haenorrhage several years ago and has since been cleared of any further follow ups. No more surgery or MRI's.

She has recently been snorkeling on the GBR and loved it but has been told by another person that she will never be able to scuba dive.

Is there any Doc that knows different or any medical evidance against this?

Cheers

G,day Gina,
Usually such a query has been addressed by one of the doctors who frequent the site by now.
I am no doctor, but in my instructing days, whenever a contentious medical problem presented, my starting point was often Dr John Parker's excellent book, The Sports Diving Medical.
(Available from DAN Asia Pacific.)
John is/was an instructor, but also a diving doctor.

On subarachnoid haemorrhage, he offers the following information:
(quote:)

Such a bleed reflects a structural change in cereral circulation, usually an aneurism, rarely an A-V malformation. This needs to be determined and assessed.
Convulsions may occur.
Consider the risk of recurrent bleed being aggravated while diving.
Consider the risks of convulsions while diving.
This risk may be reduced by delaying diving for three years.

If the aneurism has been surgically clipped, and there is no other structural abnormality of the cerebral circulation or neurological deficit and there had been no convulsions, I would recommend diving after three years.
( end quote)
Note that this is Parker's opinion only, and other doctors may disagree, but it is a more positive starting point than many would have expected for such an injury.

good luck to your friend.
Regards,
Stan
