Beyond F.A.S.T. – Other Symptoms You Should Know
- Arm/Face/Leg: Sudden numbness or weakness of the leg, arm or face. Most likely on one side of the body, with abrupt onset. Sudden trouble walking.
- Awareness: Sudden confusion or trouble understanding
- Eyes: Sudden trouble seeing in one or both eyes.
- Coordination: Sudden trouble walking, dizziness, loss of balance or coordination.
- Headache: Sudden severe headache with no known cause.
- Stomach: Possibly throwing up or the urge to be sick.
- Body: Sudden overall fatigue.
What Is a Stroke?
A stroke indicates a lack of blood flow to the brain.
A stroke, sometimes referred to as a 1) cerebrovascular accident (CVA), 2) cerebrovascular insult (CVI), or 3) colloquially brain attack is the loss of brain function due to a disturbance in the blood supply to the brain. This disturbance is due to either ischemia (lack of blood flow) or hemorrhage. As a result, the affected area of the brain cannot function normally, which might result in an inability to move one or more limbs on one side of the body, failure to understand or formulate speech, or a vision impairment of one side of the visual field.

Types of Strokes
Stroke symptoms may differ, depending upon the type of stroke, where it occurs in the brain, and how severe it is. A less severe stroke may be more difficult to recognize.
- Ischemic stroke … when a vessel supplying blood to the brain becomes blocked. It can happen for a variety of reasons. For example, fatty deposits in arteries (atherosclerosis) can cause blood clots to form. Sometimes a blood clot forms in the heart from an irregular heartbeat called atrial fibrillation. It then travels to a place where it blocks an artery supplying the brain.
- Hemorrhagic stroke … when a weakened blood vessel ruptures and bleeds into the brain. This can also happen for a variety of reasons.
- Transient Ischemic Attack (T.I.A.) … a “mini stroke” from a temporary blockage. Although a TIA doesn’t cause permanent brain damage, it may cause stroke warning signs, which may last minutes or even hours. Think of this as a warning sign you shouldn’t ignore.
A silent stroke is a stroke that does not have any outward symptoms, and the patients are typically unaware they have suffered a stroke.
- Despite not causing identifiable symptoms, a silent stroke still damages the brain, and places the patient at increased risk for both transient ischemic attack and major stroke in the future.
Conversely, those who have suffered a major stroke are also at risk of having silent strokes.
In a broad study in 1998, more than 11 million people were estimated to have experienced a stroke in the United States.
Approximately 770,000 of these strokes were symptomatic and 11 million were first-ever silent MRI infarcts or hemorrhages.
- Silent strokes typically cause lesions which are detected via the use of neuroimaging such as MRI. Silent strokes are estimated to occur at five times the rate of symptomatic strokes.
- The risk of silent stroke increases with age, but may also affect younger adults and children, especially those with acute anemia.

What to Do for a Stroke Victim
‘Call 911’ without delay when you observe any of these symptoms.
Don’t drive the patient yourself – Paramedic attention is required right away. They can begin treatment in the ambulance on the way to the hospital.
The victim himself may not be able to call 911. He may not be able to lift his arm or speak clearly. Or he may just act confused or unaware. That’s why it’s so important to understand the major signs of stroke.
IMPRESSIVE!! A powerful story about how our brains define us and connect us to the world and to one another told in:
Stroke of insight: Jill Bolte Taylor on TED.com
Meet – neuroanatomist – Jill Bolte Taylor!!! – She had an opportunity few brain scientists would wish for: One morning, she realized she was having a massive stroke. And as it happened she studied and remembered every moment. Now take a moment and listen to her story as she tells about how she felt and remembers her brain functions slip away one by one: speech, movement.
Listen to her ultimate experience she still is very emotional under – An impression that all has to do with different functioning of the neural pathways. Producing impression one will remember for ever. Keep in mind that these impressions can also manifest while you are practizing meditation. It is possible!! An experience there are no words for. Now told by a neuroanatomist! Enjoy.
