I60: Subarachnoid haemorrhage

Subarachnoid haemorrhage refers to a group of conditions characterized by bleeding within the subarachnoid space, the area located between the brain and the tissues that cover it. This medical situation often arises due to a ruptured aneurysm, an abnormal bulge in a blood vessel’s wall. When the delicate vessels of the brain break open, blood spills into the space surrounding the brain, causing sudden and severe symptoms. These can include a sudden, intense headache often described as 'the worst headache of your life,' nausea, vomiting, light sensitivity, and even a loss of consciousness. Progression of subarachnoid haemorrhage can lead to serious complications such as permanent brain damage and hydrocephalus (accumulation of cerebrospinal fluid leading to a pressure increase in the brain), and can affect various systems like the neurological and cardiovascular system. It’s not a disease that can be transmitted from person to person.
