The reason they call it a stroke is because it happens so suddenly. It happens over seconds to minutes.
Depending on the amount of damage the stroke has done to the brain, a stroke can be called a mini-stroke (or TIA transient ischemic attack) causing only few temporary symptoms, or a stroke can cause permanent paralysis to any part of the body, or it can even kill the person instantly.
Signs of a Stroke?
The National Stroke Foundation recommends the F.A.S.T. test as an easy way to remember the most common signs of stroke. Using the F.A.S.T. test involves asking these simple questions:
Face Check – their face. Has their mouth drooped?
Arm Check – Can they lift both arms?
Speech Check – Is their speech slurred? Do they understand you?
Time Is Critical – If you see any of these signs call the ambulance straight away.
Other symptoms that may occur early include problems with memory, thinking, attention, or learning. People may be unable to recognize parts of the body and may be unaware of the stroke’s effects. The peripheral field of vision may be reduced, and hearing may be partially lost. Difficulty swallowing, dizziness, and vertigo may develop.
