Bell's Palsy and a Stroke

When you suddenly notice a crooked smile, there are some conditions that you should be concerned about. These conditions may indicate a sudden change in the facial muscles, signaling a change in the course of the disease. In particular, a crooked smile can be dangerous as it is associated with serious conditions such as paralysis or stroke. Therefore, when the first symptoms occur, contact your surgeon directly.

What is Bell's Palsy?

Bell's Palsy is a neurological condition characterized by a sudden and temporary weakening or paralysis of the facial nerve (facial nerve). This condition causes muscle weakness, usually on one side of the face, which starts suddenly and occurs for no apparent reason. For this reason, the causes of the disease are not known for certain, but it is thought to be associated with viral infections (especially the herpes simplex virus). The disease affects the seventh cranial nerve, which is responsible for the movement of the muscles in the face, resulting in symptoms such as loss of facial expression on the affected side, difficulty closing the eyelid, drooping of the corner of the mouth and changes in the sense of taste.

What is a Stroke?

Stroke treatment, also known as paralysis, which is often confused with Bell's palsy, is a serious medical condition that occurs when brain cells die as a result of interrupted or reduced blood flow to the brain. This condition causes the brain cells to require oxygen and nutrients, which leads to a blockage of blood flow and the rapid death of the cells. There are two main types of this condition. The first is ischemic and the second is hemorrhagic. Ischemic stroke occurs when blood vessels to the brain are blocked by clots or other substances and accounts for 80% of stroke disorders. Hemorrhagic stroke occurs when a blood vessel in the brain ruptures, causing bleeding in the brain tissue. As a result, symptoms such as severe headache, sudden numbness or weakness in the face, arms or legs, especially on one side of the body, difficulty speaking and understanding, loss of vision, dizziness and loss of balance occur.

Symptoms of Bell's Palsy

Bell's Palsy has certain symptoms.These symptoms vary from person to person and not every symptom appears with the same severity in every patient.To examine the symptoms of Bell's Palsy in detail;

Weakness or paralysis of the facial muscles:

• Sudden and severe muscle weakness or paralysis on one side of the face.
• Incomplete closure of the eyelids.
• Sagging corners of the mouth, asymmetrical appearance of a smile or other facial expressions.
• Difficulty raising the eyebrows on the affected side of the face.

Eye Problems:

• Difficulty closing the eyelids.
• Dryness in the eye or excessive lacrimation.
• Risk of corneal damage due to the eye not closing.

Mouth and Taste Problems:

• Leakage of food and drink from the mouth due to a sagging corner of the mouth.

Pain and Discomfort:

• Pain or discomfort in the face, ear or jaw area.
• Pain behind or around the ear.

Other Symptoms:

• Headache
• Hypersensitivity to sounds (hyperacusis).
• Drooling
• Some patients have difficulty speaking or difficulty chewing food.

Symptoms of Stroke

Stroke, which is often confused with Bell's Palsy, has certain differences in terms of symptoms. These differences give precise and clear information about whether the condition is a stroke or bell's palsy. At this point, if it is necessary to examine the symptoms of paralysis in detail, they are as follows;

Suddenly Developing Symptoms

Facial Asymmetry

• Sudden numbness or weakness on one side of the face.
• One side of the mouth or eye droops when trying to smile.

Weakness in the arms and legs:

• Sudden weakness or numbness in an arm or leg, usually on one side of the body.
• One arm falls down when trying to raise the arms.

Speech Difficulty:

• Sudden difficulty in speaking, unintelligible or strange speech.
• Language problems that make it difficult to speak or understand others.

Other Common Symptoms

Vision Problems:

• Sudden loss of vision or blurred vision in one or both eyes.
• Double vision

Dizziness and Loss of Coordination:

• Sudden dizziness, loss of balance or coordination.
• Inability to maintain balance when walking or a tendency to fall.

Severe Headache:

• A sudden and severe headache of unknown origin is often described as “the worst headache I have ever had”.
• Headache may be accompanied by nausea or vomiting.

Less Common Symptoms

Loss of consciousness or fainting:

• Sudden loss of consciousness or fainting.
• Loss of the ability to be alert and react to the environment.

Swallowing Difficulty:

• Sudden difficulty swallowing (dysphagia).

How Do Doctors Diagnose Bell’s Palsy vs. Stroke?

Doctors often have to compare Bell's palsy and stroke due to their similarities, but they know that these two conditions have fundamentally different pathologies. Bell's palsy is a peripheral nerve palsy caused by sudden and usually temporary loss of function of the facial nerve (nervus facialis) and is often associated with viral infections or inflammation. A stroke, on the other hand, refers to damage to the central nervous system caused by a disruption or reduction in blood flow to a part of the brain.

Clinically, muscle weakness on one side of the face may be observed in both conditions; however, in a stroke, weakness and neurological symptoms typically appear in the lower part of the face as well as other parts of the body. Doctors carefully evaluate these differences between Bell's palsy and stroke when making a diagnosis. This is because the treatment approaches are completely different, and timely and accurate intervention is of vital importance. Additionally, examination findings such as the involvement of the forehead muscles in Bell's palsy and the preservation of these muscles in stroke are used as distinguishing features. Ultimately, doctors differentiate between the two conditions based on clinical findings, imaging methods, and the patient's overall condition, and determine the appropriate treatment plan.

How to Tell the Difference Between Bell's Palsy and Stroke?

Although Bell's Palsy and stroke are both neurological conditions characterized by sudden facial muscle weakness or paralysis, it is possible to identify their differences through their distinctive features and symptoms. For example, Bell's Palsy is a condition characterized by sudden and temporary weakness or paralysis of muscles, usually on only one side of the face, usually reaching maximum severity within 48 hours. Because of this, the facial nerves (the nerve that controls the facial muscles) become inflamed or swollen. A stroke, on the other hand, is caused by a sudden interruption or reduction in blood flow to a specific area of the brain and can present with a wider range of symptoms, such as sudden weakness in the face, arm or leg on one side of the body, slurred speech, loss of vision, loss of balance or severe headache. They are therefore two very different diseases.

At the same time, the symptoms of stroke usually appear more rapidly and widespread, while Bell's Palsy manifests itself more slowly. As a result, while stroke is diagnosed immediately, Bell's palsy manifests itself in the later stages, so the diagnosis of the disease is possible in the later stages.

Similarities Between Bell's Palsy and Stroke

Bell palsy and stroke have similar aspects in themselves. For this reason, they are quite confused. If we take a look at the similarities of these two diseases, they are as follows;

• In both cases, sudden weakness or paralysis of the facial muscles may occur. This causes marked changes in the patient's facial expression.
• Both Bell's palsy and stroke can affect one side of the face, making it appear asymmetrical.
• In both cases, patients may have difficulty speaking and swallowing. This happens because the muscles of the tongue and mouth are affected.
• In Bell's palsy and stroke, the eyelid on the affected side may not close completely. This can cause dry eyes and irritation.
• Bell's palsy and stroke involve nerve damage. In Bell's palsy the facial nerve (cranial nerve VII) is affected, while in stroke the nerve pathways and blood vessels in the brain are affected.
• Treatment and rehabilitation are important in both cases. Physical therapy and other rehabilitation methods can help restore muscle function and facial symmetry after both conditions.

Bell's Palsy and Stroke Common Risk Factors

Although Bell's Palsy and stroke both have different causes, they share some common risk factors. These common risk factors can trigger both diseases to a large extent. Therefore, by examining the data in the table below, you can learn about the common risks of Bell's palsy and stroke and pay attention to these risks.

How to Diagnosis Bell's Palsy vs a Stroke

It is possible to diagnose the difference between Bell's palsy and stroke by carefully assessing the symptoms of both conditions and performing the necessary medical tests. First of all, the patient's medical history should be evaluated. For this, factors that may be the cause of Bell's palsy and stroke should be taken into consideration. In addition, the patient will undergo a physical and neurological examination and the accuracy of the symptoms will be examined. At the same time, imaging tests (MRI or CT scan) are used to detect damage to the brain. Thus, the course of the disease is examined and the patient is diagnosed with bell's palsy or stroke.

Treatment Methods for Bell's Palsy and Stroke

Bell's palsy and stroke have their own treatment methods. These treatment methods aim to completely eliminate the disease or reduce the effects of the disease. If we need to consider these treatment methods separately;

Bell's Palsy and Treatment Methods of Stroke

Bell's Palsy Treatment Methods:

1. Corticosteroids: It is one of the most commonly used treatment methods for Bell's Palsy. Corticosteroids such as prednisone minimize nerve damage by reducing inflammation and accelerate the healing process. Accordingly, the patient shows a rapid recovery.
2. Antiviral Drugs: Because Bell's palsy can be associated with viral infections, antiviral drugs (e.g. acyclovir) may be used in some cases. However, the evidence on whether these medicines are effective is limited.
3. Physical Therapy: Physical therapy, another method of treatment for Bell's palsy, is recommended to strengthen facial muscles and increase mobility. Exercises in this direction can help the facial muscles regain their normal function.
4. Eye Care: People with Bell's palsy may find it difficult to close their eyes completely. This can lead to dry eyes and infections. Eye drops, artificial tears and an eye patch for night-time use may be recommended.
5. Pain Management: Painkillers and anti-inflammatory drugs can be used for patients who experience pain in the face or ear.

Stroke Treatment Methods:

1. Thrombolytic Therapy: Thrombolytic drugs (clot-dissolving drugs) administered within the first few hours after the onset of stroke symptoms can reduce brain damage by restoring blood flow. The most common example of these drugs is tissue plasminogen activator (tPA).
2. Antiplatelet and Anticoagulant Drugs: Blood aspirin or other antiplatelet drugs and anticoagulants (blood thinners) can be used to prevent clots in the brain in stroke.
3. Blood Pressure Control: Since high blood pressure increases the risk of stroke, it is important to keep it under control. Medications such as ACE inhibitors, beta blockers and calcium channel blockers can be used for this.
4. Cholesterol Lowering Drugs: Medicines such as statins can reduce the risk of stroke by lowering cholesterol levels.
5. Surgical Intervention: Severe narrowing or blockages in large arteries may require surgical procedures such as carotid endarterectomy or stent placement.
6. Rehabilitation: After stroke, rehabilitation services such as physical, occupational and speech therapy can help patients regain motor function, speech ability and activities of daily living.
7. Lifestyle Changes: Healthy lifestyle changes such as diet, exercise and smoking cessation can reduce the risk of stroke and support the recovery process.
