A stroke happens when a blood clot, ruptured artery, or blood vessel interrupts the flow of blood to an area in the brain. The resulting lack of oxygen and glucose (sugar) flowing to the brain causes the death of brain cells which damages the brain. This can often cause an impairment in speech, movement, and memory.
Ischemic stroke accounts for about 75% of all strokes. This occurs when a blood clot, cuts off the flow to a part of the brain. Blood clots can be formed anywhere in the body under the right conditions and travel to the brain over time if they don't dissolve.
A hemorrhagic stroke happens as a result of a blood vessel on the brain's surface rupturing and filling the space between the brain and skull with blood (subarachnoid haemorrhage) or as a result of a defective artery in the brain bursting and filling the surrounding area of the brain with blood (cerebral haemorrhage)
The end result with all of these conditions is that there is a lack of oxygen and glucose to the affected area of the brain which leads to the death of brain cells.
