Ischaemic strokes are the most common type of stroke. They happen when a blood clot blocks the flow of blood and oxygen to the brain. These blood clots typically form in areas where the arteries have been narrowed or blocked over time by fatty deposits known as plaques. The potential life-threatening condition is known to give early warning signs in your limbs. What to spot?
Ischemic stroke is one of three types of strokes and is also referred to as brain ischemia and cerebral ischemia.
This type of stroke is caused by a blockage in an artery that supplies blood to the brain.
The blockage reduces the blood flow and oxygen to the brain, leading to damage or death of brain cells.
If circulation isn’t restored quickly, brain damage can be permanent.
Approximately 87 percent of all strokes are ischemic stroke.

According to Healthline, early symptoms of an ischemic stroke include:
- Vision problems
- Weakness or paralysis in your limbs
- Dizziness
- Confusion
- Loss of coordination
- Drooping of face on one side.
One of the most common disabilities resulting from a stroke is paralysis or the inability of a muscles or group muscles to move.
The movement of the muscles is triggered by the messages sent from the brain which controls it.
The exchange of instructions between the brain and the muscles may get affected as a result of the stroke as a part of the brain stops its functions.
When the blood flow to the brain is interrupted, it causes a medical emergency known as stroke paralysis and this is a common stroke definition.
In most cases, stroke paralysis affects the opposite side where the brain is damaged due to stroke and any part of the body can be affected by it.
The immediate fallout for 90 percent of stroke-affected people is paralysis of some degree.
Nearly three-quarters of stroke survivors in the UK have leg weakness, and over three quarters have arm weakness, said the Stroke Association
The health site added: “If your muscles are weak, you could have difficulties with walking, moving your arms or holding things.
“Weakness on one side of the body is often referred to as hemiparesis (‘half-weakness’).
“Paralysis on one side of the body is called hemiplegia (‘half-paralysis’). If you have weakness or paralysis, you may need help with everyday activities.”
