Stroke is a serious threat that occurs due to decrease in blood supply to the brain. Blockage of blood supply or some problem in a blood vessel of the brain can lead to stroke. During a stroke, the brain is not able to get the required amount of oxygen and nutrients, which causes brain cells to die. Stroke requires an immediate medical intervention.
There are 3 main types of stroke:
•Ischemic strokes – Around 85% of strokes around the world are Ischemic strokes. It is caused due to blockage or narrowing of arteries connected to the brain
•Hemorrhagic strokes – It is caused by the bursting or leakage of blood from arteries in the brain. Hemorrhagic strokes can be caused by various conditions such as hypertension, blood thinning medication or weaknesses in the blood vessel walls
•Transient ischemic attacks (TIAs) –Also known as mini attack, TIAs are similar to ischemic stroked. In case of TIAs, the flow of blood to the brain is only temporarily disrupted
The symptoms of stroke are as follows:
• Sudden numbness or weakness on the face and one side of the body
• Confusion, trouble speaking and communicating
• Problem with eye sight
• Trouble walking, dizziness and loss of balance
• Severe headache
It is easy to remember the FAST acronym in order to recognize the onset of stroke.
• F – Face is dropping
• A – Arm is weak
• S – Speech is slurred
• T – Time lost is Brain lost
When a person shows symptoms related to the stroke, a neurologist has to confirm it. Along with this, the doctor also need to confirm its location and the extent of brain damage as treatment decision will based on these factors.
• Clot-busting drugs are used to treat Ischemic strokes
• For Hemorrhagic, surgery to repair or block blood vessel weaknesses is used
