I really do not have enough information to answer your inquiry, however, allow me to offer some hopefully illuminating information regarding strokes. There are three basic causes of stroke-hemorrhage, emboli, and ischemia. Hemorrhagic strokes may be caused by severe hypertension or by rupture of an aneurysm. The latter are with an individual from birth and may hemorrhage at any age, including in people in their twenties. They rupture without warning and are often fatal, taking life at times before the patient presents to hospital. Embolic strokes are sometimes associated with atrial fibrillation or heart valvular disease, and ischemic strokes are caused by a blockage in arterial circulation. The latter we believe is often caused by chronic hyperlipidemia as well as chronic elevations in blood glucose as well as chronic hypertension. For the vast majority of stroke victims, the presenting symptom of a stroke is...stroke.
