How to check for stroke?

Then, they'll do a quick check to look for signs of stroke. There are different ways to do this. Often, first responders use the Cincinnati Prehospital Stroke Scale (CPSS), where they ask you to: 1 Smile so they can see if your face looks crooked or droops on one side 2 Hold both arms out straight for 10 seconds to see if one arm drifts downward or doesn't move at all 3 Say a simple phrase, like "The sky is blue," to check if you slur your words or have trouble understanding what they're saying

Why does a stroke happen?

A stroke comes on when your brain doesn't get the blood and oxygen it needs. That could be due to a clot, known as an ischemic stroke. Or it can happen with a burst blood vessel, as with a hemorrhagic stroke. No matter which one it is, it's not long before brain cells start to die.

How many brain cells do you lose in a stroke?

No matter which one it is, it's not long before brain cells start to die. Once a stroke begins, you lose almost 2 million brain cells every minute. That's what leads to the first symptoms you have, which can seem like some part of your brain quickly went offline.

First, the longer someone suffers a stroke, the higher the chances of disability or death. “Every minute someone is having a stroke, 1.9 million brain cells are lost,” said Colleen Boyle, stroke program coordinator at Abington-Jefferson Health.

What causes brain death?

Regardless of what kind of stroke someone is suffering, the cause is a lack of blood flow to the brain, which deprives cells of oxygen. This ultimately causes brain death. 2. There are three types of stroke.

What are the three types of strokes?

The three kinds of strokes include a transient ischemic attack (TIA), ischemic stroke and hemorrhagic stroke . “When a person has a TIA, there is a short period of interruption in blood flow to the brain and the person experiences symptoms,” Boyle explained.

How long does it take for tPA to work after a stroke?

When administered quickly after stroke onset (within three hours, as approved by the FDA), tPA helps to restore blood flow to brain regions affected by a stroke, thereby limiting the risk of damage and functional impairment.

How does a stroke affect the brain?

A stroke occurs when the blood supply to brain tissue is blocked by a blood clot (ischemic stroke), or when a blood vessel in the brain ruptures (hemorrhagic stroke), causing brain cells to die and leading to functional impairments. Stroke is a leading cause of death and disability both globally and in the U.S., where approximately 800,000 people experience a stroke each year 1.

What was the role of NINDS in the development of TPA?

NINDS played a major role in the development of tPA, from funding early studies that provided a rationale for its use, to leading pivotal clinical trials that supported the treatment’s FDA approval in 1996.

When did thrombolytic therapy start?

Beginning in the 1950s , investigators first began to develop clot-dissolving, or thrombolytic, interventions for heart attacks and stroke. Early agents included the bacterial enzyme streptokinase and urokinase, an enzyme produced in the kidneys.

What is the TPA program?

The implementation of rapid treatment protocols transformed acute stroke care in the U.S., even beyond contributing to the success of tPA. Hundreds of hospitals developed organized stroke teams and resources to become primary stroke centers for tPA treatment. On the heels of tPA’s approval, NINDS launched a public awareness and education campaign to help people recognize the signs and symptoms of stroke and understand the importance of getting to the hospital quickly. This successful Know Stroke campaign 30 has reached millions through a variety of media and community programs, including programs for Spanish-speaking and minority communities.

How does tPA work?

Known by the generic name alteplase and marketed as Activase® (Genentech), tPA is given to patients through an IV in the arm, and it works by dissolving blood clots that block blood flow to the brain. When administered quickly after stroke onset (within three hours, as approved by the FDA), tPA helps to restore blood flow to brain regions affected ...

Does TPA cause bleeding?

Treatment with tPA was associated with a greater risk of bleeding in the brain , especially in patients with severe strokes. However, tPA treatment in such patients was still more likely than placebo to result in better outcomes, and mortality did not increase overall in tPA-treated patients.

Treatment

Causes

Criticism

  • \"Individually, the studies were too small to be convincing,\" said Greg Albers, MD, professor of neurology and neurological sciences and director of the Stanford Stroke Center, who was not involved in the study. \"Most of the studies showed a trend but weren't statistically significant.\"
See more on news.stanford.edu

Results

  • But when Lansberg and colleagues combined data from all four of the major tPA stroke trials to date, they saw a much clearer picture. Among a total of 1,622 patients who arrived at the hospital between three and 4.5 hours after their symptoms started, treatment with tPA improved the odds of a favorable outcome by 31 percent.

Prognosis

  • \"A favorable outcome means that patients are either completely back to normal or they have minimal symptoms, like some numbness or a slight facial droop,\" Lansberg said. \"But they can do everything in their normal life that they were able to do before the stroke happened.\"
See more on news.stanford.edu

Research

  • The study, funded by grants from the National Institutes of Health, found no change in the death rate among patients treated with tPA during the three- to 4.5-hour window. In other words, treatment improved outcomes without negatively affecting mortality. Lansberg collaborated with Vincent Thijs, MD, PhD, professor of neurology at the University Ho...

Benefits

  • \"Although this is not as good as treatment at an earlier time, it is still a highly significant benefit for patients treated in this group,\" Lansberg said.

Epidemiology

  • Albers estimates that roughly 15 percent of patients at Stanford come in during the three- to 4.5-hour time window. \"It varies by location,\" he said, \"because if you live in a remote area, you're less likely to get to the hospital in time. But with 750,000 strokes happening every year in the United States, it's quite a large number of patients who could potentially benefit.\"
