What is a subarachnoid Haemorrhage?
A Subarachnoid Haemorrhage is an uncommon type of stroke caused by bleeding on the surface of the brain. It’s a very serious condition and can be fatal.
Symptoms of a Subarachnoid Haemorrhage
There are usually no warning signs but a subarachnoid haemorrhage sometimes happens during physical exercise or straining, such as coughing, going to the toilet or lifting something heavy.
The main symptoms are:
- A sudden agonising headache – which is often described as being similar to a sudden hit on the head, resulting in blinding pain
- A stiff neck
- Feeling and being sick
- Sensitivity to light
- Blurred or double vision
- Stroke-like symptoms
A subarachnoid haemorrhage can cause both short and long-term complications.
Serious short-term complications can include further bleeding at the site of any aneurysm and brain damage caused by a reduction in blood supply to the brain.
Long-term complications include:
- Problems with memory, planning and concentration
- Changes in mood
