Publication Date:October 4, 2024

Recognizing the contrasts between Bell’s palsy and strokes is crucial according to Dr. Burak Sercan. Facial weakness can arise from either condition causing anxiety and misunderstanding. In this post we examine Bell’s palsy along with strokes and the ways to distinguish between them. Frequently asked inquiries will be addressed here to explain these essential health issues.

What is Bell’s Palsy?

This illness describes Bell’s palsy as a sudden loss of strength or paralysis in only one side of the face. Facial nerve (cranial nerve VII) is affected and manages the muscles that animate facial expressions. The onset is typically rapid, occurring within hours or days, and may be accompanied by other symptoms such as:

Facial Droop: A nod to droopiness on one side of the face may disrupt smiling and can also prevent eye closing.

Loss of Taste: Taste can change especially in the front part of the tongue.

Increased Sensitivity to Sound: In the troubled ear tones could feel elevated in intensity.

Tearing or Drooling: A handful of patients could deal with an abundance of tears or have trouble handling their spit.

Specialists consider Bell’s palsy linked to viral illnesses that provoke facial nerve swelling; however its exact origin remains unclear.

Bell’s Palsy Causes

The leading causes of Bell’s palsy involve viral illnesses. Several viruses have been implicated in its development, including:

  • Herpes Simplex Virus (HSV): The main source for cold sores is this infection.
  • Varicella-Zoster Virus: The organism that leads to chickenpox and shingles.
  • Epstein-Barr Virus: Recognized as the cause of infectious mononucleosis.
  • Cytomegalovirus: Part of the herpes virus group that can affect everyone regardless of age.
  • Influenza Virus: Bell’s palsy can develop as a consequence of the flu virus.

While anyone can develop Bell’s palsy, certain factors may increase the risk, including:

  • Family History: A person’s genetic background might be significant.
  • Pregnancy: Third trimester pregnant women face a greater risk.
  • Upper Respiratory Infections: Viral illnesses may cause swelling of the facial nerve.

What is a Stroke?

A stroke arises when there is an obstruction or reduction of blood to a brain area. Death of brain cells may take place due to this event and lead to enduring consequences for the body.

There are two main types of strokes:

Ischemic Stroke: Approximately 87% of strokes belong to this type. When a blood vessel is blocked by a clot it cuts off the brain’s blood supply. Ischemic strokes can be further classified into:

  • Thrombotic Stroke: A clot arises in a blood vessel delivering blood to the brain.
  • Embolic Stroke: A blood clot creates itself outside the brain and relocates to a brain artery.

Hemorrhagic Stroke: When a damaged blood vessel breaks apart it results in brain bleeding. Ordinary contributors are high blood pressure and aneurysms.

Consequences and measure of a stroke change with the brain region damaged and the length of interrupted blood supply.

Most Common Stroke Causes

Numerous elements raise the probability of suffering a stroke. These might be: 

High Blood Pressure: This is the main reason behind a majority of stroke occurrences because it harms blood vessels and raises the likelihood of blood clots.

Heart Disease: Problems like atrial fibrillation can generate clots that migrate to the brain causing strokes. 

Diabetes: Damage to blood vessels raises the chance of stroke.

High Cholesterol: May cause plaque to accumulate in the arteries which narrows them and raises the chance of clots.

Smoking: Boosts the chances of harm by destroying blood vessels and cutting down oxygen in the blood.

Obesity: Related to increased risks of diabetes and cardiovascular problems.

Physical Inactivity: Being inactive can cause obesity and heighten risk factors.

Family History: A genetic factor can raise the chance of developing risks.

Conclusion

It is essential to discern between Bell’s palsy and strokes for effective and swift treatment. Though both ailments exhibit facial weakness their origins and effects vary greatly. Should you feel sudden facial weakness promptly seek medical advice to find out the cause and secure the required support.

According to Dr. Burak Sercan rapid intervention plays a key role in enhancing recovery after both Bell’s palsy and strokes. Learning about these conditions helps us guarantee quick and efficient medical attention for improved health and wellbeing.

FAQ

How can you tell the difference between Bell’s palsy and a stroke?

You may see similar symptoms in Bell’s palsy and stroke such as facial weakness. However, several key differences can help differentiate between the two:

Onset: In Bell’s palsy symptoms arise quickly; however stroke signs may appear slowly or abruptly.

Forehead Movement: Due to the muscle involvement in Bell’s palsy the forehead cannot raise the affected eyebrow. The forehead is generally exempt from stroke effects which enables the ability to elevate the eyebrow.

Other Symptoms: Neurological symptoms often accompany strokes including talking difficulties and loss of balance.

How to tell the difference between forehead wrinkle Bell’s palsy and stroke?

To distinguish between forehead wrinkle issues related to Bell’s palsy and stroke, observe the following:

Facial Symmetry: The whole side of the face is impacted by Bell’s palsy along with the forehead. Forehead muscles may continue to work with stroke cases permitting the patient to raise their brows and form wrinkles on their forehead.

Response to Commands: Request the person to lift both eyebrows. People with Bell’s palsy have trouble moving the impacted side. Meanwhile stroke patients can demonstrate limited movement on the affected side.

Is Bell’s palsy forehead sparing?

Bell’s palsy includes the forehead in its symptoms. A distinction of Bell’s palsy is that people can’t raise their eyebrow on the affected side which creates a flat forehead. Strokes often leave the forehead unharmed.

What should you avoid if you have Bell’s palsy?

  • If you have Bell’s palsy, consider the following recommendations to aid recovery:
  • Avoid Stress: When symptoms worsen from stress it is vital to look for relaxation strategies.
  • Limit Facial Strain: Avoid activities that exhaust your facial muscles and focus on reducing strain on them.
  • Avoid Cold Exposure: Keep the sensitive side of your face warm to avoid pain.
  • Avoid Rubbing the Eyes: Due to the difficulty of closing the eye on the affected side rubbing it should be avoided to prevent irritation or harm.

What should you avoid if you have a stroke?

  • After experiencing a stroke, certain precautions can help prevent future incidents:
  • Avoid Smoking: The chance of having another stroke is higher for smokers.
  • Limit Alcohol Intake: Alcohol abuse can boost blood pressure levels and lead to hazards.
  • Avoid High-Sodium Foods: Cutting back on sodium helps regulate blood pressure.
  • Limit Physical Inactivity: Participate in consistent exercise that healthcare experts recommend.

Should you go to the ER for Bell’s palsy?

Though Bell’s palsy does not generally jeopardize a person’s life a consultation with a medical professional is necessary if symptoms occur abruptly. A consultation can identify if serious ailments like a stroke are a possibility. Look for immediate medical help if facial paralysis happens on top of symptoms related to a stroke like difficulty speaking or leg weakness.
