Bell’s palsy causes an unexpected weakness in facial muscles, in rare cases it can affect both sides. The patient’s history and neurologic exam will decide if the facial shortcoming is central or peripheral. If it is central and MRI is required to test for infectious and inflammatory diseases, if it is peripheral no tests will be suggested immediately. The median age is 40 years old for Bell’s palsy but can happen at any age, 3 years old has been the lowest. The number of cases for Bell’s palsy is 20 per 100,000 population per year and increases with age. The causes of Bell’s palsy are unknown but threats include diabetes, and a recent upper respiratory tract infection. Corticosteroids and antivirals are used to treat Bell’s palsy, no …show more content…
It can happen any age youngest reported has been 3, middle age is 40, and highest age is people over 70. Progress is slow and recovery times vary. With treatment or without treatment most people begin to recover within 2 weeks after initial start of indicators. Most people recover completely within 3-6 months however, symptoms may last longer. Herpes simplex virus type 1 (HSV-1) has been strongly implied as a cause of Bell’s palsy.

Bell’s palsy causes pain and stress to the body. The individual or family would have to pay for ER visit, eye drops, eye patch, and treatment meds. Being sensitive to sound and light can keep the patient possibly out of work. Also, loss of movement in the face patients will lose their ability to taste, chew, and drink.

Bell’s Palsy is usually triggered by inflammation and oedema in the facial nerve canal resulting in demyelination of the facial nerve usually due to HSV-1. HSV is the etiologic agent in this virus, once a cold sore is on the lips the virus moves up the axons of the sensory nerves and exist in in the geniculate ganglion which is located in facial canal of the head. In times of stress, the virus reboots and triggers destruction to the myelin. Moreover HSV, other possible etiologies for Bell’s palsy is herpes zoster, Lyme disease, syphilis, Epstein-Barr viral infection, cytomegalovirus, HIV, inflammation alone, upper

In the event that shortcoming is central an MRI (not routinely indicated) is required to test the patient for infectious and inflammatory diseases. On the off chance that facial shortcoming is peripheral no tests will be immediately indicated. Unless other cranial-nerve deficits obtain, or no recovery 3-6 weeks after the start of the symptoms. Facial retraining such as mime therapy may improve stiffness and lip movement also can lessen the threat of motor synkinesis. Corticosteroids and acyclovir are prescribed to patient to help facial-muscle strength. One study determined 3 months or later corticosteroids was better than acyclovir after treatment. But with both was superior combination in restoring facial-muscle
