The Medical Minute: When it comes to a stroke, 'time is brain'

HERSHEY, Pa. — Staff at Penn State Health Milton S. Hershey Medical Center know the drill and that every second counts.

For them, it starts like this: an Emergency Medical Services provider calls into the hospital to let them know they’re arriving with someone having a “brain attack.”

“It’s an activation. An alert,” said Cesar Velasco, stroke program coordinator at the medical center. “The estimated time of arrival from EMS gives us time to be prepared.”

Emergency doctors and nurses get ready, and, at a comprehensive stroke center like Milton S. Hershey Medical Center, so does the neurology team. When the patient arrives, neurosurgeons and neurologists jump in to examine the patient and interview family members and the emergency response team.

“The assessment is quick, because ‘time is brain,’” Velasco said. “We know that every hour your brain is losing valuable neurons that help it function normally. So, the sooner we can treat them, the better the outcomes.”

At Milton S. Hershey Medical Center, doctors can help a patient suffering a stroke in various ways. They provide acute interventions that include intravenous medication that dissolve clots and endovascular thrombectomy, which is a surgical procedure to remove a clot causing disruption of blood flow to the brain. These treatments are time sensitive and can only be delivered to patients who meet acute treatment criteria. 

But none of it can happen without that first 911 call.

Health care experts like Velasco need friends, family and bystanders to spring into action as quickly as they do. An understanding of the warning signs that precede a stroke can make all the difference when, as it does for 795,000 people every year in the U.S., someone has a stroke.

See below for the details about the two major types of stroke and how to recognize when someone might need help. Read them, save them and share them with others.

How can I detect a stroke?

Different people can have different feelings, called 'symptoms,'  when they have a stroke. It depend on what part of the brain is affected. The key to detecting a stroke is knowing the most commons signs of stroke. One way to remember is to remember the acronym "BE FAST":

  • B is for Balance — Does the person seem unsteady when trying to stand or walk?
  • E is for Eye — Has the person lost vision in one or both eyes?
  • F is for Face — Does the person's face droop or look uneven when smiling?
  • A is for Arms — Is one arm hanging down?
  • S is for Speech — Is the person's speech slurred? Does the person have trouble speaking or seem confused?
  • T is for Time — Call 911 now!

What causes a stroke?

A stroke happens when blood flow to the brain is blocked or a blood vessel breaks. A part of the brain stops working because it does not get the blood supply that it needs. These are two types of stroke:

  • Ischemic Stroke — An area that blood cannot get to. Blood flow is blocked. (Pronounced is-key-mick)
  • Hemorrhagic Stroke — An area with bleeding. A broken blood vessel leaks blood into the brain. (Pronounced hem-or-raj-ick)
