Understanding Strokes: Causes, Symptoms, and Prevention
Oct 07, 2023 By Madison Evans

Strokes are a common, deadly disease. Your brain gets a stroke, or brain attack, when it lacks blood. Your brain controls your body. Suppose its blood flow stops suddenly, like a quick blackout. If you have a clot or a blood vessel that bursts, this can quickly change how you move, talk, and think.

Strokes are explained in this article. It's important to understand the signs of a stroke, its types, prevention, and causes. Learning about strokes is like knowing about a storm before it happens. It lets us immediately protect ourselves and the people we care about. Let's begin this learning trip by talking about strokes and how to put our health first.

Symptoms of Stroke

Some of the warning signs of a stroke are:

Inability to Move

Your face, arm, or leg may suddenly numb, weak, or paralyzed. Usually, this is localized to one side of the body. Experiment with bringing both arms up over your head simultaneously. Stroke symptoms include a drooping arm. In addition, you may notice that when you try to smile, one side of your lips drops.

Affected Vision

Impairment of vision affecting one or both eyes. One or both of your eyes may become abruptly cloudy or dark, or you may have temporary double vision.


If you suddenly get a severe headache, which leads to other symptoms like nausea, dizziness, or changes in your awareness, it might be a sign of a stroke.

Difficulty In Understanding and Expressing

You can get muddled thinking, slur your words, or need help following conversations.

Difficulty In Walking

If you try to do that, you might easily hurt yourself. Vertigo and poor coordination are two of the potential negative effects.

Types of Strokes

There are primarily three main types of strokes:

  • Ischemic Stroke
  • Hemorrhagic Stroke
  • Transient Ischemic Attack

Ischemic Stroke

Ischemic strokes occur when brain tissue dies from lack of oxygen. Although blood clots are the leading cause, other factors may contribute. Insufficient blood flow of oxygen and nutrients is ischemia. If this happens to parts of your brain, you'll lose the functions that those parts usually handle. Losing even a few brain cells can have catastrophic effects and cause death.

What Causes Ischemic Stroke?

These factors can cause an ischemic stroke:

  • Hardening of the arteries.
  • The embolism causes a clot to go to the brain and block an artery.
  • Clots develop in cerebral blood arteries
  • Damage to the brain's tiny blood vessels.
  • Heart disease causing brain clot

Symptoms of Ischemic Stroke

The following are some of the symptoms you might experience in ischemic stroke.

  • Difficulty articulating words clearly (dysarthria).
  • Disturbance of focus or diplopia.
  • Vertigo or dizziness.
  • Stiff neck.
  • Mood swings and abrupt personality shifts.
  • Disorientation or restlessness.
  • Amnesia.
  • Tension headaches are often severe and unexpected.
  • Having a loss of consciousness.
  • Coma.

Hemorrhagic Stroke

Headaches, fatigue, nausea, and vomiting are among the symptoms that may accompany a hemorrhagic stroke, caused by the continuous buildup of blood.

What are the factors that lead to a hemorrhagic stroke?

Hemorrhagic stroke can happen due to the following reasons:

  • High Blood Pressure
  • Ballooning and bursting of weakened blood vessels.
  • Abnormal blood vessel tangles that cause blood vessels to rupture.
  • Severe head injury causing blood vessel rupture.
  • Blood-Thinning Medications
  • Liver Disease

Symptoms of Hemorrhagic Stroke

A rupturing blood artery can cause hemorrhagic strokes with life-threatening symptoms like:

  • Becoming unconscious
  • Unable to move or feel
  • Confused and irritable
  • Shoulder and neck muscle ache
  • Nausea, vomiting
  • Light sensitivity
  • Seizure
  • Vision issues
  • Drooping eyelids
  • Larger pupil in one eye

TIA (transient ischemic attack)

Brain blood flow interruption causes TIA. Like an ischemic stroke, blood flow is blocked for a few minutes to hours. A transient clot or obstruction in a brain artery causes TIAs.

TIAs don't usually cause lasting damage, but they are very important signs of a problem with the brain's blood flow. People with TIAs need to see a doctor immediately so they don't turn into full-blown strokes. If you get the proper diagnosis care and change your lifestyle, you can significantly lower your chance of having another stroke.

What Causes TIA?

Some things that can make you more likely to have a TIA are:

  • Hypertension, or high blood pressure
  • Being fat
  • Consuming a lot of fats in the diet.
  • Drinking too much alcohol daily
  • Abnormal heartbeat
  • living with diabetes

Symptoms of TIA

Transient ischemic episodes often only last a few minutes. Most patients report improvement within an hour, while some may experience symptoms for up to 24 hours. TIA stroke symptoms might include the abrupt development of stroke warning signals such as:

  • Paralysis, numbness, or weakness
  • Problems communicating or comprehending people due to slurred speech
  • Experiencing partial or total blindness
  • Disorientation, imbalance, or inability to coordinate.


To prevent strokes effectively, focus on managing key risk factors:

Maintaining Weight

Stay at a healthy weight by following a program of healthy eating and regular exercise designed just for you with the help of your doctor. Stroke risk can be drastically lowered by losing even a small amount of weight. Losing weight can prevent a mini-stroke. But, for preventing strokes, one needs to incorporate a healthy diet in one’s routine.

Engaging in Regular Physical Activity

Do some moderate activity, like walking, for 30 minutes most days of the week. This benefit both weight control and general cardiovascular health maintenance.

Low to Moderate Alcohol Intake

Keep your alcohol consumption low. Drinking red wine in moderation may help your heart, but too much might have the opposite impact.

Reduce Your Blood Pressure

Keep your blood pressure healthy (below 120/80) with a diet low in sodium and abundant in fruits, vegetables, fish, and whole grains; moderate exercise; and any necessary medication.

Diabetes Management

Control your diabetes with your doctor-recommended regimen of close monitoring, a healthy diet, regular exercise, and, if necessary, medication or insulin.
