A high intraluminal pressure will lead to extensive alteration in endothelium and smooth muscle function in intracerebral arteries.
The increased stress on the endothelium can increase permeability over the blood-brain barrier and local or multifocal brain oedema.

In most cases it is impossible to pinpoint an exact cause. However, there are a number of risk factors that have been linked to high blood pressure.
