Cranial mononeuropathy is a disorder that is evidenced by your cranial nerve VII not functioning like it should. Cranial nerve VII is your facial nerve. Cranial mononeuropathy is a disorder in which you are unable to control your facial muscles on the side that is affected.
There are several different conditions that may result in facial paralysis. These include a brain tumor, Lyme disease or a stroke. However, if no specific cause for your facial paralysis can be discovered, your disorder is probably cranial mononeuropathy.
About 40,000 people are affected by cranial mononeuropathy each year in the United States. Although cranial mononeuropathy can occur at any age, it is rare when it affects anyone under the age of 15 or over the age of 60.
One of the causes of cranial mononeuropathy is when your cranial nerve VII becomes swollen and inflamed due to an infection that is usually caused by a virus. The leading cause of cranial mononeuropathy is the herpes simplex virus. Genital herpes and cold sores are also caused by this same virus. There are also other viruses that have been connected with cranial mononeuropathy. These include the viruses that cause mononucleosis, shingles and chicken pox.
