Subarachnoid haemorrhage
In terms of the Erlangen Community Stroke Registry:Sub means under, arachnoidea is a part of the soft cerebral membrane surrounding the brain. In some people the vessels, which supply the brain with blood, form sack-like bulges (aneurysms; the disposition is mostly congenital) when passing through the cerebral membrane. If these bulges burst, blood streams between the brain surface and the soft cerebral membrane. In 40 percent of cases, the blood also enters into the brain tissue. Vascular defects can be caused by increasing the head internal pressure, for example during sex, lifting heavy objects, by strong pressing at defecation or vomiting. Subarachnoid haemorrhages are responsible for about five percent of all strokes and occur mainly in younger people. The main symptom is a fulminant, utterly severe, unbearable headache and neck pain.
