Full Answer

A stroke is called subacute when it has been one week to a month since its onset, according to HealthTap. Within its first week a stroke is called acute, and after a month, chronic. Other possible stroke symptoms include sudden severe unexplainable headaches and walking imbalance.

There are two types of stroke: ischemic and hemorrhagic, says the Cleveland Clinic. Ischemic stroke occurs when blood flow to brain cells is blocked by clots that have formed in blood vessels in the brain or elsewhere, having then travelled to the brain. Excessive plaque from cholesterol and fatty deposits can also clog the blood vessels of the brain, causing ischemic stroke. Of all strokes, about 80 percent are ischemic.

Hemorrhagic stroke happens with the rupture or breaking of a brain blood vessel, with blood then seeping into tissue and damaging cells. Hemorrhagic stroke is most commonly caused by brain aneurysms and high blood pressure. Controllable risk factors for stroke include atrial fibrillation, diabetes, obesity and smoking, states the Cleveland Clinic.
