Stroke A hemorrhagic stroke occurs when a blood vessel in part of the brain becomes weak and bursts open. This causes blood to leak into the brain. Some people have defects in the blood vessels of the brain that make this more likely.

What is stroke? A stroke is a brain attack. It can happen to anyone at any time. It occurs when blood flow to an area of brain is cut off. When this happens, brain cells are deprived of oxygen and begin to die. When brain cells die during a stroke, abilities controlled by that area of the brain such as memory and muscle control are lost.

Stroke A stroke occurs when the brain is deprived of the oxygen it needs due to an interruption of its blood supply. Without oxygen brain cells die. The oxygen deprived area of brain tissue is called an infarct.

Stroke In Cats - All About Feline Stroke The term ‘stroke’ refers to a sudden loss or reduction of the blood supply that is reaching the brain, and falls into one of two categories in both cats and people: Haemorrihagic Stroke, which is the term used for a stroke caused by bleeding within the brain.

- Stroke is when poor blood flow to the brain results in cell death. There are two main types of stroke: ischemic, due to lack of blood flow, and hemorrhagic, due to bleeding. They result in part of the brain not functioning properly. Signs and symptoms of a stroke may include an inability to move or feel on one side of the body, problems understanding or speaking, feeling like the world is spinning, or loss of vision to one side among others.

What Does a Mini Stroke Mean? A mini stroke occurs when there is a temporary period during which there is a lack of blood flow to an area of the brain. This is similar to a stroke, with the difference being that a mini stroke improves because blood flow is quickly restored before permanent brain injury can occur.

Stroke What is a stroke? A stroke is a life-threatening medical emergency that happens when the blood supply to part of the brain is cut off. The blood supply may be cut off by a blood clot or from a burst blood vessel. A person having a stroke may lose control over their movement, perception and speech. They may also lose consciousness.

Stroke Signs, Symptoms, Warning Signs, and Treatments 1 A hemorrhagic stroke describes brain tissue that is damaged because of bleeding, most often because of uncontrolled high blood pressure.  A stroke is a medical emergency. The patient or family needs to call 9-1-1 (activate EMS) to access emergency care.

Stroke: Symptoms Causes & Treatment What is a Stroke. A stroke is the rapidly developing loss of brain functions due to a disturbance in the blood vessels supplying blood to the brain. This can be due to ischemia (lack of blood supply) caused by thrombosis or embolism or due to a hemorrhage. A stroke occurs when the supply of blood to the brain is suddenly interrupted.

Stroke  In-Depth Report Paralysis or problems controlling movement (motor control) Paralysis is one of the most common disabilities resulting from stroke. The paralysis is usually on the side of the body opposite the side of the brain damaged by stroke, and may affect the face, an arm, a leg, or the entire side of the body.

Medical Definition of Stroke Definition of Stroke. Stroke: The sudden death of brain cells due to lack of oxygen, caused by blockage of blood flow or rupture of an artery to the brain. Sudden loss of speech, weakness, or paralysis of one side of the body can be symptoms. A suspected stroke can be confirmed by scanning the brain with special X-ray tests, such as CAT scans.

Stroke An ischemic stroke is typically caused by blockage of a blood vessel, though there are also less common causes. A hemorrhagic stroke is caused by either bleeding directly into the brain or into the space between the brain's membranes.

Medical Definition of Stroke volume home / medterms medical dictionary a-z list / stroke volume definition Medical Definition of Stroke volume Stroke volume: The amount of blood pumped by the left ventricle of the heart in one contraction. The stroke volume is not all the blood contained in the left ventricle; normally, only about two-thirds of the blood in the ventricle is expelled with each beat. Together with the heart rate, the stroke volume determines the output of blood by the heart per minute (cardiac output).

Heart Disease and Stroke Knowing the signs of a stroke is the first step in stroke prevention. A stroke, sometimes called a brain attack, occurs when blood flow to an area in the brain is cut off. The brain cells, deprived of the oxygen and glucose needed to survive, die.

What is stroke? Stroke by the Numbers. Each year nearly 800,000 people experience a new or recurrent stroke. A stroke happens every 40 seconds. Stroke is the fifth leading cause of death in the U.S. Every 4 minutes someone dies from stroke. Up to 80 percent of strokes can be prevented. Stroke is the leading cause of adult disability in the U.S.

Glossary Stroke (“ brain attack ”) is a disease of the blood vessels in and around the brain. It occurs when part of the brain does not receive enough blood to function normally and the cells die (infarction), or when a blood vessel ruptures (hemorrhagic stroke).

What Is Stroke? Stroke is a sudden impairment in brain function. One may suffer an inability to speak or speak clearly, walk, or move a limb because blood has stopped flowing to an area of the brain. Usually, this is caused by the blockage, or the rupture, of a blood vessel.

- Stroke is linear/reciprocating motion converted into rotary motion by a (4-bar) chain. Power stroke pushes piston away from TDC whence there can be utmost one of it per revolution, as in a 2-stroke engine ( or 4-stroke double acting). In the case of 4-stroke engine - one power stroke plus one for suction - requires 2 revolutions to a cycle - i.e. 1 power stroke in 2 revolutions. Rather elementary.
