Stroke Symptoms, Signs, Causes, And Treatments

Below, you’ll find must-know information about stroke.

A stroke is a medical emergency that occurs when the blood supply to a part of the brain is interrupted or reduced, causing brain cells to die. Strokes can be caused by either a blockage or a burst blood vessel in the brain.

A stroke is also known as a cerebrovascular accident (CVA). It is a critical medical situation that arises when there is an interruption in the flow of blood to the brain.

The occurrence can arise from either the bursting of a blood vessel or the formation of a blood clot, resulting in a grave outcome of injuring brain cells that can have far-reaching implications.

Various factors can amplify the chances of a stroke. Among them, high blood pressure, which has the potential to inflict harm to blood vessels and make them susceptible to blockage or rupturing, is one of the most prevalent.

Additional factors that could increase the likelihood of a stroke are smoking, obesity, elevated cholesterol levels, diabetes, and having a family history of strokes.

Strokes can be classified into two main types: ischemic and hemorrhagic. Ischemic strokes emerge when a blood clot impedes blood flow in an artery located in the brain, whereas hemorrhagic strokes take place when a blood vessel in the brain breaks and causes bleeding in the neighboring tissue.

Both types of strokes have the potential to inflict substantial harm to the brain, with the stroke’s intensity being reliant on the area and scale of the affected region.

The grave nature of strokes cannot be overstated, with potentially long-lasting consequences that include paralysis, impaired language comprehension and speaking, memory loss, and cognitive damage. In severe instances, strokes may even culminate in death.

Recognizing the symptoms may aid in preventing the aggravation of the situation, while timely treatment can remarkably ameliorate the prognosis and reduce the possibility of long-standing incapacity.

Hence, it’s best to know the symptoms of a stroke. Below are stroke symptoms worth knowing about.

8. Numbness Or Paralysis

Numbness or paralysis is a result of a blood flow interruption to a certain brain area during a stroke. This can be due to a blood clot obstructing an artery (ischemic stroke) or a blood vessel bursting and resulting in bleeding into the brain tissue (hemorrhagic stroke).

This disruption can result in the damage or death of brain cells in that specific region, causing the loss of function, such as numbness or paralysis, in the corresponding part of the body.

7. Confusion

Confusion is a common symptom of stroke caused by a blood clot. The interruption of blood flow can prevent affected brain cells from receiving sufficient oxygen and nutrients, leading to their malfunction.

As a result, cognitive impairments, such as confusion, may arise. The severity of this particular symptom is determined by the location and extent of the brain damage caused by the stroke.

6. Trouble Seeing

The onset of a stroke can also result in difficulty seeing. In some cases, both eyes could be affected. This happens when the nerve controlling eye movement is deprived of blood flow and sustains damage.

This damage can cause the eyes to not work in tandem, leading to difficulty in focusing, blurred vision, and double vision (diplopia).

5. Trouble Speaking

Trouble speaking is another possible symptom of a stroke. This is caused by the damage to the regions of the brain that control language and speech, such as Broca’s area or Wernicke’s area.

This can happen when there is an interruption in the blood circulation to the brain caused by a blood clot or a ruptured blood vessel.

4. Trouble Walking

Trouble walking or maintaining balance is a frequent manifestation of stroke. When a stroke damages or kills brain cells, communication between different parts of the brain and the body can be disrupted.

This can cause difficulty in performing tasks that were once simple, such as walking short distances or standing upright.

3. Difficulty In Swallowing

When you experience difficulty swallowing, which is medically referred to as dysphagia, it could be a result of the muscles used in swallowing being affected by damage to the brain.

During a stroke, brain cells can be damaged or die. This could lead to dysphagia and the severity of it depends on the extent and location of the brain damage.
