How To Predict A Stroke: Early Warning Symptoms

Given that 90% of strokes is preventable, it is essential to recognize the warning signs and seek for immediate medical help, in order to limit the damage and save the life of the person affected. Continue reading to learn how to predict a stroke by identifying some of the most common early warning symptoms.

 

October 29 has been declared World Stroke Day. The stroke (also known as ischemia/cerebral hemorrhage) has, unluckily, become a common disease, affecting more than 15 million people all over the world and causing 6.7 million deaths, which represents 12% of worldwide deaths.

I have decided to deal with this topic, as 3 of my wife’s grandparents died of a stroke. Since then, my wife has always wondered if immediate and proper medical help could have saved their lives.

Over the last years more and more people have been affected by stroke, and the onset of this disease is linked to the lowering of the age at which it manifests itself. While the average age at which people are affected by stroke was 69-71, nowadays even people around 50 suffer from it, not to mention some cases of young people and, unluckily, children. Stroke is, then, a disease affecting not only the elderly.

What is a stroke?

 

A stroke is a medical condition in which poor blood flow to the brain results in cell death. There are two main types of stroke: ischemic, due to lack of blood flow, and hemorrhagic, due to bleeding. They result in part of the brain not functioning properly.

 

There exists another form of stroke, called transient ischemic attack (TIA): a brief episode of neurological dysfunction caused by loss of blood flow (ischemia) in the brain, without tissue death (infarction). TIAs have the same underlying mechanism as ischemic strokes. Both are caused by a disruption in blood flow to the brain, or cerebral blood flow (CBF).

40% of people suffering from TIA, are likely to suffer from a stroke in the future.

It is of vital importance to seek for medical help in the first few hours following the stroke, in order to restore the oxygenation to the affected areas and prevent neuron death, which may result in serious disability and, in some cases, even death.

Among the types of stroke, the ischemic attack is the most common.

Since it is referred to as a brain attack, stroke, just like a heart attack, needs immediate medical care, in order to minimize the damage and reduce the risk of disability and even death. Being able to recognize the early symptoms is essential, not only in order to promote the chance of recovery, but also to save your own life and the life of a beloved person.

 

Stroke: early warning symptoms

 

Stroke symptoms are related to the brain area or areas affected and mainly include:

• sudden numbness, weakness, pins and needles of the face, arm, leg, on one side of the body;
• mental confusion;
• difficulty speaking and understanding;
• vision issues (one or both eyes);
• difficulty walking;
• dizziness, loss of balance and co-ordination;
• sudden severe headache, with nausea, vomiting and loss of consciousness.
• drooping of the mouth & face dropping;
• partial or total loss of sensibility in one arm/leg on the same side of the body.

In 1998 a group of UK physicians developed the FAST protocol, designed to be an integral part of a training package for ambulance staff. This protocol was created to speed up the administration of intravenous tissue plasminogen activator to patients within 3 hours of acute stroke symptom onset. F.A.S.T. is an acronym that stands for:

Facial drooping,

Arm weakness,

Speech difficulties and

Time to call emergency services.

We all should use F.A.S.T. to remember and identify the early warning signs of a stroke.

 

What to do?

 

Stroke is a medical emergency, be it TIA, ischemia or hemorrhage.

On the onset of the first symptoms, you have to ask the affected person to:

• raise the arms, in order to understand whether one side is weaker than the other and tends to drop;
• try to smile, to see if one side of the mouth drops;
• repeat a simple phrase, to check if the speech is strange.

As soon as you have realized it might be a stroke, you must take the person affected to the hospital or call an ambulance right away.

From the onset of the very first symptoms, you have 60 minutes to provide with medical assistance and save the life of the person. In fact, within 60 minutes you must arrive at the hospital, where within 3-4 hours, the patient is being given drug therapy (thrombolytics), that, in case of a stroke, breaks up the clot and promotes the chance of recovery by 30 %. In a few cases, within 6 hours surgery is needed to break up the clot (aggressive embolectomy).

What NOT to do?

 

If you think it is a stroke, YOU MUST NOT:

• waste time.
• lie in bed, waiting for the symptoms to disappear spontaneously.
• call your general practitioner – you MUST call 911 instead or go to the hospital right away.

 

Risk factors:

 

The main 3 risk factors that may cause the onset of a stroke are:

1. high blood pressure,
2. diabetes,
3. hypercholesterolemia, also called high cholesterol.

 

Other factors are:

• smoking (either active or passive);
• alcohol;
• obesity;
• previous TIA;
• atrial fibrillation (an abnormal heart rhythm characterized by rapid and irregular beating of the atria);
• family history;
• sedentary life style;
• age (the incidence of cerebrovascular events doubles by every decade after 55 years of age);
• stress;
• cardiopathy;
• migraine;
• taking the pill.

The best prevention when it comes to a stroke, is to have an active life style, to get rid of bad habits (like smoking and drinking alcohol), opt for a well-balanced diet (less salt, alcohol, fatty foods and red meat, and more omega-3-rich foods, magnesium, potassium, antioxidants, vitamin C, E, B6, B12 and folates) and manage stress properly, since nowadays it seems impossible to avoid it as a whole.

Actually, a healthy life style helps to reduce the stroke risk by 80%. Whereas a 30-minute walk a day (at a speedy pace) helps reduce those blood inflammation factors responsible for causing a stroke (C-reactive protein and interleukin 6) and reduce the stroke risk by 50%.

 

Knowing how to predict a stroke by identifying its early warning symptoms can be lifesaving. It is extremely important to be well-informed and everybody should know about the first signs of ischemia/hemorrhage, in order to take prompt action and save their own life or the life of a beloved person.
