Who Is Affected by Bell's Palsy?
Bell's palsy is the most common type of facial paralysis.
It may be related to a virus such as
herpes simplex or
herpes zoster. It seems to be more likely to occur in
people who have
diabetes, and it may be more likely in pregnant women.
Bell's palsy affects:
- About 25 people out of 100,000.1 That
means about 75,000 Americans are affected each year.
- Equal numbers
of men and women.2
- People between the ages
of 15 and 40 years in most cases, although it can occur at any age.3
