First you need to know that a stroke is a rapid loss in brain function due to an alteration in blood supply. Then you have to know that the lack of blood flow may be due to a thromboembolic cause (something is blocking normal flow) or an hemorrhoagic cause (bleeding causes lack of blood distal to the tearing of the artery). Another classification is according to the site on which the alteration occurs; intracranial or extracranial.
With all this in mind, you have that haemorrhoagic strokes are caused mainly due to hypertension, rupture of an aneurysm, AVM or brain trauma. Thromboembolic strokes may be caused by atherosclerosis, arteritis or an embolus from outside the brain.
Intracranial causes are AVMs, atherosclerosis, aneurysms, arteritis or external compresion of a blood vessel (tumor). Extracranial causes are emboli from the carotid arteries, left atrium, left ventricle or the aorta.
