If there is a blood clot or plaque that blocks a blood vessel in the brain or a blood vessel in the brain breaks or ruptures, then it causes a Stroke.
Ischemic – Obstruction within a blood vessel supplying blood to the brain.
Hemorrhagic Stroke – When a weakened blood vessel ruptures.
Transient Ischemic Attack – Caused by a temporary clot. Often called a “mini stroke”.
• There are two types of hemorrhagic strokes
– Intracerebal (blood vessel inside the brain bursts and leaks blood into surrounding brain)
– Subarachnoid (caused by a burst aneurysm )
• The spilled blood flows into or around the brain
• Creates swelling and pressure, thereby damaging cells and tissue in the brain
• High blood pressure and aging blood vessels are the most common causes of this type of stroke
Though a stroke is identified as something that happens to older people and the elderly, it can happen to children and when it does, it is called a pediatric stroke. It usually occurs as a side effect when the child is sick with some other illness.
Sickle cell disease (SCD) is the most common cause of childhood stroke. Usually stroke occurs in 17 to 24 percent of children with SCD, most often between the ages of 3 and 10.
