5 Warning Signs of Stroke

What is the FAST test for a stroke?

Pre-strokes or mini strokes are the common terms used to describe a transient ischemic attack (TIA). Unlike a full blown stroke, a TIA only lasts a few minutes and does not cause permanent damage. Nevertheless it is a warning sign that a possible stroke may be coming in the future.
Drinking enough water regularly prevents dehydration. This may play a role in keeping the blood less viscous, which in turn prevents a stroke.
The warning signs of stroke include: Weakness or numbness of the face, arm or leg, usually on one side of the body. Trouble speaking or understanding. Problems with vision, such as dimness or loss of vision in one or both eyes.
Background and Purpose— Although stroke is strongly associated with hypertension, some individuals with normal blood pressure (BP) experience a stroke.
- Warning signs of an ischemic stroke may be evident as early as seven days before an attack and require urgent treatment to prevent serious damage to the brain, according to a study of stroke patients published in the March 8, 2005 issue of Neurology, the scientific journal of the American Academy of Neurology.
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.
A silent stroke refers to a stroke that doesn't cause any noticeable symptoms. Most strokes are caused by a clot that blocks a blood vessel in the brain. The blockage prevents blood and oxygen from reaching that area, causing nearby brain cells to die.
The three main types of stroke are:
When people use the term "ministroke," what they're really often referring to is a transient ischemic attack (TIA). A TIA is a brief interruption of blood flow to part of the brain, spinal cord or retina, which may cause temporary stroke-like symptoms but does not damage brain cells or cause permanent disability.
Ischemic stroke, also called dry stroke, occurs when a blood vessel in the brain is blocked. Dr. Colorado notes that dry strokes make up about 70 percent of strokes they see. “The blood supply doesn't get to the brain and brain cells die from that,” he says. The blockage prevents proper blood flow.
An ischaemic stroke is caused by a blockage cutting off the blood supply to the brain. This is the most common type of stroke. A haemorrhagic stroke is caused by a bleeding in or around the brain. A transient ischaemic attack or TIA is also known as a mini-stroke.
A Level 1 stroke alert is a patient with LKN 0-8 hours prior, and results in the Vascular Neurology team responding immediately to the emergency department. A Level 2 stroke alert is a patient LKN 8-24 hours prior.
Stress can cause the heart to work harder, increase blood pressure, and increase sugar and fat levels in the blood. These things, in turn, can increase the risk of clots forming and travelling to the heart or brain, causing a heart attack or stroke.
Some people have strokes without realizing it. They're called silent strokes, and they either have no easy-to-recognize symptoms, or you don't remember them. But they do cause permanent damage in your brain. If you've had more than one silent stroke, you may have thinking and memory problems.
Signs of Stroke in Men and Women
Strokes are usually diagnosed by doing physical tests and studying images of the brain produced during a scan.
High blood pressure can cause the arteries that supply blood and oxygen to the brain to burst or be blocked, causing a stroke. Brain cells die during a stroke because they do not get enough oxygen.
