A stroke, or cerebrovascular accident (CVA), occurs when blood supply to part of the brain is disrupted, causing brain cells to die.
These risk factors include,high blood pressure
, diabetes, and smoking.
Small strokes may not cause any symptoms, but can still damage brain tissue. These strokes that do not cause symptoms are referred to as silent strokes.
five major signs of stroke:
1-Sudden numbness or weakness of the face, arm or leg, especially on one side of the body. The loss of voluntary movement and/or sensation may be complete or partial. There may an associated tingling sensation
in the affected area.
2-Sudden confusion or trouble speaking or understanding. Sometimes weakness in the muscles of the face can cause drooling.
3-Sudden trouble seeing in one or both eyes
4-Sudden trouble walking, dizziness
, loss of balance or coordination
5-Sudden, severe headache
with no known cause
what to do?
The first action should be to activate the emergency medical system in your area .The goal is to get the stroke victim to a hospital as quickly as possible to confirm the diagnosis.
While waiting for the ambulance, the following first aid suggestions may be helpful
1-The affected person should lie flat to promote an optimal blood flow to the brain.
, unresponsiveness, or nausea are present, the person should be placed in the rescue position on their side to prevent choking should vomiting occur.
3-Although aspirin plays a major role in stroke prevention ,once the symptoms of a stroke begin, it is generally recommended that additional aspirin not be taken until the patient receives medical attention. If stroke is of the bleeding type, aspirin could theoretically make matters worse. Moreover, patients with stroke may have swallowing difficulties
and may choke on the pill.
Ask the patient to do the following:
1-Smile: the face should move symmetrically
2-Raise both arms: looking for weakness on one side of the body
3-Speak a simple sentence
these are the basic thing to be done
