Bell's Palsyenparentshttps://kidshealth.org/EN/images/headers/P-bellsPalsy-enHD-AR1.jpgBell's palsy is a temporary weakness or paralysis of the muscles on one side of the face. Though it can be alarming, it typically goes away in a matter of weeks.bell's palsy, bells palsy, facial paralysis, nerve problems, facial nerves, muscles problems, facial weakness, nerve problems, muscle weakness, half the face is frozen, one side of the face is frozen, one-sided paralysis, one side of face is weak, frozen face08/14/200711/20/201709/02/2019Rupal Christine Gupta, MD03/14/2015932e0ce4-56f5-4cfa-b9bd-bfc968703219https://kidshealth.org/ws/RadyChildrens/en/parents/bells-palsy.html/<p>Bell's palsy is a sudden weakness or paralysis on one side of the face that makes it hard for a person to move the mouth, nose, or eyelid. It also can make that side of the face droop or look stiff.</p> <p>Bell's palsy happens when a facial nerve is not working as it should, often after a virus.</p> <h3>What Causes Bell's Palsy?</h3> <p><span>There is </span>a&nbsp;facial nerve on each side&nbsp;of the&nbsp;face.<span>&nbsp;</span>When they are working properly, they carry many messages from the brain to the face. These messages may tell an eyelid to close, one side of the mouth to smile or frown, or salivary glands to make spit.</p> <p>But if a nerve swells and is compressed, as happens with Bell's palsy, these messages don't get sent correctly. The result is weakness or temporary paralysis of the muscles on one side of the face.</p> <p>Bell's palsy is most often connected with a viral infection such as HSV-1 (the virus that causes <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/cold-sores.html/">cold sores</a>), Epstein-Barr (the virus that causes <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/mono.html/">mononucleosis</a>), or <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/flu.html/">influenza</a> (the flu). It also can happen&nbsp;with ear infections, bad colds, <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/lyme.html/">Lyme disease</a>, and trauma to the head or face.</p> <p>In a few people, the immune system's response to a viral infection leads to swelling of the facial&nbsp;nerve. Because it's swollen, the nerve gets compressed as it passes through a small hole at the base of the skull and stops sending the correct messages from the brain to the face &mdash; messages that, among other things, tell one eyelid to blink and the front of the tongue to taste things.</p> <h3>Signs and Symptoms</h3> <p>Often the virus or infection that causes Bell's palsy is so mild that some kids don't ever feel sick. Usually the virus or infection has passed before the symptoms of Bell's palsy begin.</p> <p>Bell's palsy tends to happen quickly. Some kids may feel pain behind or in front of their ears for a few hours or even days before the facial weakness sets in.</p> <p>Because Bell's palsy only happens to one facial nerve at a time, it only affects one side of the face. Some kids have only slight weakness; others might not be able to move that side of their face at all. This may make one half of the child's face (especially the mouth) seem to droop or sag.</p> <p>Other symptoms can include:</p> <ul> <li>a feeling as though one side of the face is "twisting" or "tugging" (this is caused by the healthy side making facial expressions &mdash; the muscles pull on the weak side)</li> <li>headache</li> <li>trouble tasting at the front of the tongue</li> <li>trouble producing saliva</li> <li>sounds seeming louder than usual in one ear</li> <li>difficulty fully shutting one eye, causing watering</li> <li>twitching in the eye</li> <li>a dry or irritated eye</li> </ul> <p>Bell's palsy affects only the facial muscles, so if other parts of the body are stiff or paralyzed, talk with your doctor right away, as it may be a sign of a different condition.</p> <h3>Diagnosis and Treatment</h3> <p>There isn't a specific test for Bell's palsy. To make sure the paralysis is Bell's palsy and not another condition, your doctor will ask how long it took for the symptoms to develop and where the weakness or paralysis is.</p> <p>People who have strokes usually have weakness only in the lower half of their face and may have it in their arms and legs as well. The problems caused by tumors usually take longer to develop (the symptoms start more slowly and get more serious over a longer period of time) than Bell's palsy does.</p> <p>The doctor will ask if your child is having weakness or paralysis in other parts of the body, or is having other problems, like double vision or trouble swallowing. The doctor will also want to know about any head injuries.</p> <p>If you live in an area of the country where Lyme disease is common, your doctor may do a blood test to check for that infection.</p> <p>If the facial paralysis lasts more than a few months, the doctor is&nbsp;likely to recommend further tests &mdash; such as X-rays, <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/ct-head.html/">computed tomography (CT) scans</a>, and <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/mri.html/">magnetic resonance imaging (MRI)</a> &mdash; to rule out other problems. The doctor&nbsp;also might recommend that your child have an electromyography (EMG), which tests the nerves' signals and how well the muscles are responding to them.</p> <p>Usually,&nbsp;the virus or infection that leads to Bell's palsy has passed, so there's no specific treatment used&nbsp;for the condition. It goes away once the swelling of the nerve goes down and the nerve recovers from any damage. The nerve has to renew itself and that can only happen with time.</p> <p>In some cases, doctors recommend medicines to help reduce the swelling or prescribe an eye patch or eye drops if the eye is dry. You also can ask about facial exercises, relaxation techniques, and massage that may help some people with Bell's palsy.</p> <p>Most people recover fully within 1 to 3 months, whether or not the condition is treated, although some will have permanent weakness in their face afterward. It is very unusual for anyone to get&nbsp;Bell's palsy twice.</p> <p>Making sure your child eats well&nbsp;and gets&nbsp;plenty of sleep are important to healing. Activities and sports participation don't have to be limited as long as your child can close the eye (to protect it). If the eye can't be closed, talk with the doctor about using protective glasses or a patch to prevent eye damage.</p> <h3>Helping Kids Cope</h3> <p>Bell's palsy can be tough for kids because it affects their appearance so dramatically. Reassure your child that his or her face will soon return to normal.</p> <p>If your child&nbsp;is being teased, consider talking with teachers, school counselors, and coaches &mdash; you might even want to speak to the&nbsp;class, if your child is comfortable with that. You also can practice responses with your child in case people ask what's wrong, stare, or say unkind things. Most people will be understanding if you explain that it's a temporary medical problem that isn't contagious.</p> <p>With a little patience, and some extra doses of love and support from you, your child will be feeling better very soon.</p>
Brain and Nervous SystemThe brain controls everything we do, and is often likened to the central computer within a vast, complicated communication network, working at lightning speed.https://kidshealth.org/ws/RadyChildrens/en/parents/brain-nervous-system.html/1e2a5004-5865-4069-97fd-5488c31075b9
Cold SoresCold sores are small and painful blisters that appear around the mouth, face, or nose. They're very common and, while uncomfortable, usually go away on their own.https://kidshealth.org/ws/RadyChildrens/en/parents/cold-sores.html/0540751d-619e-48a1-9bac-db333d33b641
Immune SystemThe immune system, composed of special cells, proteins, tissues, and organs that protect against germs and microorganisms, is the body's defense against disease.https://kidshealth.org/ws/RadyChildrens/en/parents/immune.html/d5495b69-ecfe-4b16-a87f-a9f5664e71d6
Lyme DiseaseLyme disease can affect the skin, joints, nervous system, and other organ systems. If Lyme disease is diagnosed quickly and treated with antibiotics, most people feel better quickly.https://kidshealth.org/ws/RadyChildrens/en/parents/lyme.html/d17f5ce5-05a0-4d44-92e2-490eccd510ec
Mononucleosis (Mono)Mononucleosis - or "mono" - is an infection that causes flu-like symptoms. It usually goes away on its own in a few weeks with the help of plenty of fluids and rest.https://kidshealth.org/ws/RadyChildrens/en/parents/mono.html/8abe3795-0878-4611-9ea5-a905d0933c3c
StrokesThis "brain attack" happens when blood flow to the brain stops, even for a second. Often, kids who have a stroke can learn to use their arms and legs and speak again through brain retraining.https://kidshealth.org/ws/RadyChildrens/en/parents/strokes.html/5539d27a-a31c-459d-9bfc-94b934761cda
The Flu (Influenza)Flu symptoms tend to come on quickly and are worse than the sneezing and stuffiness of a cold. The flu is very contagious. Find out what to do in this article for parents. https://kidshealth.org/ws/RadyChildrens/en/parents/flu.html/dfdd8061-bafc-4f1f-97dd-884d29a5f6e3
