Neurovascular Disease 

Any damage to the neurovascular system can result in significant impact to a patient’s functional status. 

Subarachnoid haemorrhages are bleeds into the subarachnoid space, the anatomical space between the arachnoid mater and pia mater. They will classically present with a severe headache, sudden onset, typically in the occipital region (often termed “thunderclap” headaches). The mainstay of treatment is to definitively treat the bleeding region and reduce potential complications.

Brain arteriovenous malformations (bAVMs) on the other hand are defects in the vascular system of the brain that are typically asymptomatic and subclinical. However, of those presenting symptomatically, half will present with haemorrhage, therefore intervention is required when identified to prevent further morbidity.
