Stroke: What You Need to Know
Posted May 22, 2023 by Dr. Madihah Hepburn, Medical Director, Neurocritical Care.
Strokes are very common, with one occurring every 40 seconds United States. A stroke is a medical emergency requiring immediate attention – the longer symptoms are left untreated, the more damage a stroke can cause. Since fast care is necessary, knowing the signs and symptoms is essential so you can help someone get the care they need right away.
BE FAST and dial 911: Recognize the SUDDEN symptoms of a stroke.
- Balance: Did the person suddenly lose balance?
- Eye: Has the person lost vision in one or both eyes?
- Face: Does the person’s face look uneven or drooping?
- Arm: Is one arm hanging down?
- Speech: Is the person having difficulty speaking?
- Time: Call 911 now!
About Strokes
A stroke is an abrupt interruption of blood flow to the brain that causes loss of neurological function. The interruption of blood flow can be caused by a blockage or bleeding in the brain.
A stroke is usually categorized as one of two types
- Ischemic. About 80 percent of all strokes are ischemic, which means there is a blockage or lack of blood supply to an area of the brain, resulting in some cells dying. This happens when blood vessels in the brain become narrow or clogged, cutting off blood flow to the brain cells.
- Hemorrhagic. This type of stroke occurs when there is a tear in the wall of an artery in the brain. Leaking or rupturing occurs, producing bleeding into or around the brain.
The effects of a stroke, including the severity of those effects, depend on where in the brain it has occurred and the extent of the damage.
Since brain cells require a constant supply of oxygen to stay healthy and function properly, blood needs to be supplied continuously to the brain through two main arterial systems:
- The carotid arteries come up through each side of the neck to the front of the brain.
- The basilar and vertebral arteries begin at the base of the skull and run up along the spine, joining the brain through the back of the neck.
Blockage of blood flow to the brain for even a short period of time can be disastrous and cause permanent brain damage or even death. Therefore, quick medical attention is critical to the patient’s future.
Stroke Treatment
Again, time is critical when treating a person suffering from a stroke. The sooner a person arrives at the emergency department (ED), the sooner treatment can begin to better their chances for recovery. When a patient arrives, the care team must act quickly. Using innovative technology, the patient receives advanced CT stroke imaging and other tests to locate any medical issues found in the brain, blood vessels and blood flow.
Medical management, including clot-busting drug therapies, is usually the first course of action, as long as arrival to the ED is within four and half hours of symptom onset. Minimally-invasive techniques, such as cerebral angiography, are then used to remove any clots that may be causing the stroke. Medical advancements in treating stroke have saved lives and restored stroke patients’ quality of life. Before these innovations, lives could have been lost or patients may have been severely disabled.

According to the CDC, someone in the US has a stroke every 40 seconds. Those patients who receive emergency care greatly increase their rate of survival and shorten recovery time.

When a patient comes in and is diagnosed with a stroke, medications can be administered intravenously to break up and restore blood flow back to the brain. However, this…
In May, we celebrate Stroke Awareness Month. Stroke is the fifth leading cause of death, and the leading cause of adult disability. A stroke occurs when part of the brain does not get blood flow. A blood clot can block a blood vessel or artery, or a blood vessel can break. When this occurs, brain cells die quickly. When the cells die, the body loses control of the abilities that area of the brain once controlled.
