Middle Cerebral Artery (MCA)
Infarction
The middle cerebral artery (MCA) is the most common artery involved in stroke. It supplies a large area of the lateral surface of the brain and part of the basal ganglia and the internal capsule via four segments (M1, M2, M3, and M4).
What is the most common type of stroke?
Most strokes (87%) are
ischemic strokes
. An ischemic stroke happens when blood flow through the artery that supplies oxygen-rich blood to the brain becomes blocked. Blood clots often cause the blockages that lead to ischemic strokes.
Which is more common thrombotic or embolic stroke?
There are 2 kinds of ischemic stroke: thrombotic stroke and embolic stroke. Together, the two types of ischemic stroke account for about 87% of all strokes. Thrombotic stroke, the most common type, happens when a blood clot (called a thrombus) blocks the blood flow to parts of the brain.
Which type of stroke is most often caused by a rupture of an atherosclerotic plaque in a cerebral artery resulting in occlusion of the artery?
Ischemic stroke
– (most common – 87% of cases) is caused by a blockage of an artery from a blood clot (thrombus) or from clogged blood vessels due to atherosclerosis (hardening of the arteries).
Can brain repair itself after stroke?
Fortunately, damaged brain cells are not beyond repair.
They can regenerate
— this process of creating new cells is called neurogenesis. The most rapid recovery usually occurs during the first three to four months after a stroke. However, recovery can continue well into the first and second year.
Which side of brain is worse for stroke?
The terms
Left Brain
Stroke and Right Brain Stroke refer to the side of the brain where the obstruction causing the stroke occurs. There is not a worse or better side to have a stroke on as both sides control many important functions, but a more severe stroke will result in amplified effects.
Is ischemia a stroke?
Ischemic stroke is
one of three types of stroke
. It’s 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.
Which artery causes stroke?
Carotid artery disease
occurs when fatty deposits (plaques) clog the blood vessels that deliver blood to your brain and head (carotid arteries). The blockage increases your risk of stroke, a medical emergency that occurs when the blood supply to the brain is interrupted or seriously reduced.
What is the most common cause of ischemic stroke?
Ischemic stroke occurs when a
blood clot blocks
or narrows an artery leading to the brain. A blood clot often forms in arteries damaged by the buildup of plaques (atherosclerosis). It can occur in the carotid artery of the neck as well as other arteries. This is the most common type of stroke.
What type of stroke is an embolic stroke?
An embolic stroke is
one of two types of ischemic strokes
. It occurs when a blood clot forms in another part of the body — often the heart or arteries in the upper chest and neck — and moves through the bloodstream to the brain.
Can hardening of the arteries cause a stroke?
Stroke is also known as a cerebral vascular accident. Most ischemic strokes are caused by
atherosclerosis
, which is also called hardening of the arteries.
Can plaque in arteries cause a stroke?
Plaques that rupture cause the formation of blood clots that can block blood flow or break off and travel to another part of the body. In either of these cases, if a clot blocks a blood vessel that feeds the heart, it causes a heart attack. If it blocks a blood vessel that
feeds the brain
, it causes a stroke.
Can you live 20 years after a stroke?
Study of long-term survival rates among the younger population – A recent Dutch study focusing specifically on 18 to 50 year olds found that among those who survived past one month mark,
the chances of death within twenty years were 27% for those suffered an ischemic stroke
, with TIA sufferers coming in second at 25%, …
What happens in the first 3 days after a stroke?
During the first few days after your stroke, you
might be very tired and need to recover from the initial event
. Meanwhile, your team will identify the type of stroke, where it occurred, the type and amount of damage, and the effects. They may perform more tests and blood work.
What fruit is good for stroke?

- Pomegranate (Antioxidants) …
- Tomatoes (Lycopene) …
- Nuts and Seeds (Vitamin E) …

Why are stroke victims so mean?
