Neonatal hemorrhagic stroke
Most people think of stroke as a disease of old age. But newborns have as high a risk of stroke as the elderly. Stroke in the first 28 days of life is much more common than parents realize. Yet stroke in this fragile age group remains largely unrecognized and thus untreated.
A stroke is a sudden stoppage or decrease in the flow of blood in the brain, severe enough that it causes damage to the brain. There are two types of stroke: ischemic and hemorrhagic:
Ischemic stroke is when the blood flow to the brain is diminished, usually because of a clot, called a thrombus, in one of the blood vessels in the brain. There are two types of ischemic stroke that occur in children, especially newborns: sinovenous thrombosis, where there is a clot in one of the veins in the brain, and arterial ischemic stroke, where the clot is in an artery in the brain.
Hemorrhagic stroke is when a blood vessel in or near the brain ruptures, causing bleeding in the brain.
