A stroke is a dangerous cerebral event that can lead to lasting, devastating effects or even death. It is the result of interrupted blood flow to the brain; without blood and oxygen, the brain begins to die. There are three main types of stroke: Transient ischemic attack (TIA) or “mini stroke,” ischemic stroke, and hemorrhagic stroke.
TIA can be thought of as a warning sign for a future stroke attack. It is the result of temporarily blocked blood flow with symptoms only lasting for a short period. Ischemic and hemorrhagic strokes, however, have lasting effects.
It is estimated that 87% of strokes that occur are ischemic. They are the result of a clot-preventing proper blood flow to a section of the brain. Depending on the origin of the clot, an ischemic stroke can be either embolic or thrombotic. Embolic strokes are the result of a blood clot breaking off from a different location and traveling to the brain. Once in the brain, the clot lodges in a small enough blood vessel, blocking blood flow. Thrombotic strokes occur when the blood clot originated in the brain, eventually accumulating to block blood flow altogether. Both types of ischemic stroke require treatment to get rid of the blood clot to prevent further damage.
There are two types of hemorrhagic strokes: intracerebral and subarachnoid. Intracerebral hemorrhages are the most common type of hemorrhagic stroke. They happen when a blood vessel in the brain bursts and leaks blood into the surrounding tissue. The blood that was leaked puts pressure on the surrounding blood cells and damages them. Subarachnoid hemorrhages occur when there is bleeding in the area between the brain itself and the thin tissue that covers it (called the subarachnoid space). Hemorrhagic strokes can be caused by high blood pressure, aneurysms or arteriovenous malformation, which has to do with an abnormal connection between veins and arteries.
All types of stroke can lead to life-threatening situations and severe complications. If you or a loved one have suffered from a recent ischemic stroke, call CBC Health today to see if cord blood treatment could be right for you (855) 426-4623. Request more information here.
