A stroke happens when the patient’s brain stops working due to a shortage of blood supply. It is a medical emergency that affects not just the patient but also their family. From the first symptoms, there is only a three to five-hour window to restore normal brain function using anti-clot medication.
After that, brain damage becomes permanent. Neurology specialists in St. George deal with the treatment of the central nervous system, and so if you suspect that your loved one is having a stroke, you know what department to find.
Someone might be having a stroke if their face droops, they have speech difficulties and their arms grow weak. The following are types of stroke:
This stroke happens when a vessel supplying blood to the brain becomes clogged. The brain cells begin to die minutes later due to lack of nutrients and oxygen. An Ischemic thrombotic stroke happens if the affected blood vessel is inside the brain.
This is an Ischemic stroke that is caused by a blood clot that gets to the brain through the bloodstream without necessarily having formed there. Heart surgery or disease often causes embolic strokes. They occur without any warning signs resulting in high and severe casualties.
A hemorrhagic stroke occurs when a blood vessel supplying to the brain ruptures. When this happens, brains cells become starved of nutrients and oxygen. Additionally, pressure builds in the surrounding tissue causing irritation and swelling.
Similar to ischemic stroke, bleeding can be from blood vessels in the brain or the space between the brain and the subarachnoid space.
A stroke victim can get recurrent strokes within five years of the first one. The risks continue to increase with time and with them, the risk of severe disability or death. Therefore, care is necessary for a loved one with a prior stroke incident.
