A stroke is a medical emergency that occurs when the blood supply to part of the brain suddenly stops. If the brain does not receive oxygen and nutrients from the blood, the brain cells die. Signs of stroke include weakness, confusion, trouble seeing in one or both eyes, sudden trouble with walking, dizziness, loss of balance and sudden severe headache with no known cause.

Top Stroke Facts

Stroke is a major cause of serious long-term disability.

Stroke occurs in two forms. One is ischemic (blockage of a blood vessel supplying the brain), and the other is hemorrhagic (bleeding into or around the brain).

Ischemic strokes are caused by a thrombus or embolus that blocks blood flow to the brain.

Hemorrhagic strokes are caused by uncontrolled high blood pressure or head injury.

According to the CDC, every year, more than 795,000 people have a stroke in U.S, which kills on an average, one person every 4 minutes.

Around 87% of strokes in the US are ischemic strokes.

After coronary heart disease, stroke is Australia’s second biggest killer.

Stroke often results in disability that cuts off the patient’s ability to carry out daily activities.

The common treatments for ischemic stroke are Tissue Plasminogen Activator (tPA) and endovascular procedures.

The common treatments for hemorrhagic stroke are endovascular procedures and surgical treatment.
