Brain stroke happens when there is a blockage in the blood circulation in the brain or when a blood vessel in the brain breaks and leaks. The burst or blockage prevents blood and oxygen reaching the brain tissue. Without oxygen the tissues and cells in the brain are damaged and die in no time leading to many symptoms
A stroke occurs when a blockage or bleed of the blood vessels either interrupts or reduces the supply of blood to the brain. When this happens, the brain does not receive enough oxygen or nutrients, and brain cells start to die.
Types of Brain Stroke
Brain stroke is mainly two types.
Ischemic stroke: It is the most common type and contributes to 80% of brain strokes.
Hemorrhagic stroke: It contributes to 20% of brain strokes.
What are the Symptoms of a Brain Stroke?
Sudden numbness or weakness in the face, arm or leg, especially on one side of the body.
Difficulty understanding speech
Sudden trouble seeing in one or both eyes
Sudden trouble walking, dizziness
Loss of balance or lack of coordination
Sudden severe headache with vomiting or unconsciousness
How are Brain Strokes Treated?
Treating a stroke depends on many different factors. The most important factor in determining treatment is what kind of stroke a person has.
Ischemic: If this happens fast enough, it’s sometimes possible to prevent permanent damage or at least limit a stroke’s severity. .
Hemorrhagic: Reducing blood pressure is often the top priority because this will reduce the amount of bleeding and keep it from getting worse. Another treatment option is to improve clotting so the bleeding will stop.
How are Strokes Diagnosed?
A healthcare provider can diagnose a stroke using a combination of a neurological examination, diagnostic imaging and other tests. During a neurological examination, a provider will have you do certain tasks or answer questions. As you perform these tasks or answer these questions, the provider will look for telltale signs that show a problem with how part of your brain works.
