Can a stroke be mistaken for Bell's palsy?
Bells Palsy and Stroke Symptom Similarities
Because of the urgent nature of a stroke, an accurate diagnosis is crucial. Both a stroke and Bell's Palsy can cause patients to have partial facial paralysis, which is why one is occasionally mistaken for the other. Either can render an entire side of your face immobile.
Bell's palsy is not caused by a stroke, but it can cause similar symptoms. If you have facial weakness or drooping, see your health care provider if you have facial weakness or drooping to find out the underlying cause and severity of the illness.
A diagnosis of Bell's palsy is made based on clinical presentation—acute facial nerve weakness or paralysis on one side of the face with onset in less than 72 hours—and by ruling out other possible causes of facial paralysis. There is no specific laboratory test to confirm diagnosis of the disorder.
A stroke occurs due to the blockage of a blood vessel in the brain. Motor neurons traveling from the cortex of either brain hemisphere stimulate facial muscles on the opposite side of the body. Thus, when a stroke impacts one hemisphere of the brain, it will cause facial weakness in the opposite side of the face.
A peripheral lesion, such as Bell's Palsy, interrupts the innervation after the motor commands from both hemispheres have joined, so that the forehead is paralyzed.
The early symptoms of Bell's palsy may include a slight fever, pain behind the ear and weakness on one side of the face. The symptoms may begin suddenly and progress rapidly over several hours and sometimes follow a period of stress or reduced immunity. The whole side of the face is affected.
These are the most common symptoms of Bell's palsy: Disordered movement of the muscles that control facial expressions, such as smiling, squinting, blinking, or closing the eyelid. Loss of feeling in the face. Headache.
There's no specific test for Bell's palsy. Your health care provider will look at your face and ask you to move your facial muscles by closing your eyes, lifting your brow, showing your teeth and frowning, among other movements.
Therefore, you should seek emergent medical care if you notice facial weakness or drooping. Although Bell's palsy can be alarming, it's rarely serious. Many people begin to improve in about 2 weeks, even without treatment. It is important to be seen as soon as possible.
- corticosteroid drugs, which reduce inflammation.
- antiviral or antibacterial medication, which may be prescribed if a virus or bacteria causes your Bell's palsy.
- over-the-counter pain medications, such as ibuprofen or acetaminophen, which can help relieve mild pain.
What helps Bell's palsy go away faster?
Facial exercises and physical therapy for Bell's palsy help to increase muscle strength and to regain facial coordination from this temporary facial paralysis. Most exercises should be done three or four times a day in short sessions, with up to 30 repetitions per exercise.
Bell palsy is thought to be due to swelling (inflammation) of the facial nerve in the area where it travels through the bones of the skull. This nerve controls movement of the muscles of the face. The cause is often not clear. A type of herpes infection called herpes simplex or herpes zoster might be involved.
Call 9-1-1 immediately if any of these signs of stroke appear: Numbness or weakness in the face, arm, or leg; Confusion or trouble speaking or understanding speech; Trouble seeing in one or both eyes; Trouble walking, dizziness, or problems with balance; severe headache with no known cause.
- Face – the face may have dropped on 1 side, the person may not be able to smile, or their mouth or eye may have drooped.
- Arms – the person may not be able to lift both arms and keep them there because of weakness or numbness in 1 arm.
A silent stroke may be the most difficult to pinpoint. This type of stroke doesn't always produce noticeable symptoms, such as facial drooping. However, doctors can diagnose a silent stroke from a brain scan. The symptoms of a silent stroke usually come on gradually and affect an individual's lifestyle over time.
"If you cannot wiggle your eyebrow or smile, more likely than not this is Bell's palsy, assuming you can still move your arm and leg without problem," he said. "But if you can move your eyebrow and you cannot smile, then that's more often than not a stroke."
One response to severe stress is that the body's immune system is weakened. The weaker the body's immune system, the less functional the body's systems are. A weakened immunity can lead to parts of the body not functioning correctly, such as with Bell's Palsy.
DON'T stop taking your medicines or change your dose because you feel better unless your health care provider tells you to. DON'T reduce your activity level. Rest doesn't help Bell's palsy. DON'T stop corticosteroids abruptly; they must be tapered.
Bell's palsy causes temporary paralysis, or palsy, of facial muscles. It occurs when a condition, such as a viral infection, causes inflammation and swelling of the seventh cranial nerve (the nerve that controls facial muscles). With Bell's palsy, your face droops on one side or, rarely, both sides.
How long does Bell's palsy last? In the majority of cases, facial paralysis from Bell's palsy is temporary. You're likely to notice gradual improvement after about two weeks. Within three months, most people have recovered full motion and function of their face.
What type of virus causes Bell's palsy?
Bell's palsy is caused by an inflammation of the facial nerve. This inflammation may be caused by a virus. There is some evidence that the virus is often herpes simplex virus (HSV), the same virus that causes cold sores and genital herpes.
For those who do not fully recover, they are often left with chronic disability. The most recent study shows that although the Scottish Study of 2007 influenced a change in management, shockingly 44% of people diagnosed with Bell's palsy still remain untreated.
Immediate action required: Call 999 if:
somebody's face droops on 1 side (the mouth or eye may have drooped) a person cannot lift up both arms and keep them there. a person has difficulty speaking (speech may be slurred or garbled)
Although no certain cause has been established, people newly diagnosed with Bell's palsy should understand that they are unwell. It is important to get plenty of rest even if they have no other symptoms and to maintain a healthy diet. If you are at work or school, it may be necessary to take some time to recover.
If you have any signs of Bell's palsy, you should see a doctor or nurse because treatment is effective but should be started within two to three days of onset.
Avoid stringy, chewy foods and those with pips, skins, shells, or husks, (e.g. raw tomatoes, lettuce, chewy meats, sweet corn, peas, baked beans).
Apply low heat, such as a gel pack or heating pad, to help relieve pain and swelling. Gently massage the area. Talk to your doctor if you have severe pain.
Intake of vitamin C-rich foods should be encouraged in the general population especially in those who already possess risk factors for Bell's palsy and in patients with Bell's palsy as well. Supplementation with vitamin C tablets should only be started if deficiency is found in serum levels.
Advice on facial nerve disorders
The patient with unilateral peripheral facial paralysis should rest the first days that are associated with significant anxiety and worry, and should not drive.
The 5 Musts-Do's When First Diagnosed with Bell's Palsy:
REST (If you have a new baby, this means calling in the family or a night nanny. You MUST sleep for the nerve to regenerate.
How long does it take for Bell's palsy to peak?
Symptoms typically peak in the first week and then gradually resolve over three weeks to three months. Bell's palsy is more common in patients with diabetes, and although it can affect persons of any age, incidence peaks in the 40s.

Difference in Symptoms
If the cause is Bell's palsy, watch for symptoms such as watering from the eye on the affected side of the face, changes in the ability to taste, sound sensitivity, and ringing ears. With a stroke, watch for trouble finding words, eyes gazing in one direction, trouble walking, and vision changes.
Symptoms of a TIA
Face – the face might drop on one side, the person may not be able to smile or their mouth may have dropped, and their eyelid may droop. Arms – the person may not be able to lift both arms and keep them there because of arm weakness or numbness in one arm.
Blurred vision or partial/complete vision loss may be signs that you are having a stroke. Sudden vision changes could also have other causes. If you have a sudden change in your vision, you should see a doctor and have it checked out.
Yes, you can have a stroke and not know it. A stroke's effects can be undetectable if the stroke is small or if the tissue damaged does not serve a critical function. Evidence of the stroke would show on a CT scan or an MRI of the brain, but it might not produce symptoms.
Blood tests for stroke. There is no blood test that can diagnose a stroke. However, in the hospital, your doctor or nurse may do a series of blood tests to learn the cause of your stroke symptoms: Complete blood count (CBC).
Pre-strokes or mini strokes are the common terms used to describe a transient ischemic attack (TIA). Unlike a full blown stroke, a TIA only lasts a few minutes and does not cause permanent damage. Nevertheless it is a warning sign that a possible stroke may be coming in the future.
How to tell the difference between Bell's palsy and stroke eyebrow?
"If you cannot wiggle your eyebrow or smile, more likely than not this is Bell's palsy, assuming you can still move your arm and leg without problem," he said. "But if you can move your eyebrow and you cannot smile, then that's more often than not a stroke."
Conditions that may mimic Bell's palsy include CNS neoplasms, stroke, HIV infection, multiple sclerosis, Guillain-Barré syndrome, Ramsay-Hunt syndrome, Melkersson-Rosenthal syndrome, Lyme disease, otitis media, cholesteatoma, sarcoidosis, trauma to the facial nerve, autoimmune diseases such as Sjogren's syndrome, and ...
Face drooping is one of the most common signs of a stroke. One side of the face may become numb or weak. This symptom may be more noticeable when the patient smiles.
Many people are aware of the obvious signs of a stroke such as an excess drooping of the face due to relaxed muscles, but the fact is, there can also be silent stroke symptoms. This means it is completely possible to have a stroke without even noticing.
The person is typically asked to raise their eyebrows, close their eyes and smile. If the person has Bell's palsy, their eyebrows will rise asymmetrically, they won't be able to close the affected eye and one side of the mouth will droop.
It occurs when a condition, such as a viral infection, causes inflammation and swelling of the seventh cranial nerve (the nerve that controls facial muscles). With Bell's palsy, your face droops on one side or, rarely, both sides. You may have a lopsided smile, or an eyelid that won't close.
With Bell's palsy, facial weakness can occur in a peripheral pattern in which the forehead mouth, eye, and forehead are affected. Bell's palsy can hinder a patient's ability to grimace or smile, open or close the eye, and lift or furrow their eyebrow.
Bell's palsy occurs when the seventh cranial nerve becomes swollen or compressed, resulting in facial weakness or paralysis. The exact cause of this nerve damage is unknown, but many medical researchers believe it's most likely triggered by a viral infection.
One response to severe stress is that the body's immune system is weakened. The weaker the body's immune system, the less functional the body's systems are. A weakened immunity can lead to parts of the body not functioning correctly, such as with Bell's Palsy.
Stroke-Related Headaches
Oftentimes, the area affected by the headache is directly related to where the stroke occurs. For example, a blocked carotid artery can cause a headache on the forehead, while a blockage towards the back of the brain can cause a headache towards the back of the head.
