Causes of Bell's Palsy
The exact cause of Bell's palsy is unknown. It is suspected that an irritated facial nerve becomes swollen. As the facial nerve passes through narrow openings in the skull, it is compressed and symptoms result.
Doctors believe a herpes virus may cause the nerve to become inflamed, and, in turn, cause Bell's palsy. Lyme Disease or other infections may also be a cause of facial weakness.
Paralysis of the facial nerve may also be caused by:
- Head or facial injuries
- Tumors
- Cancer or infection in the cerebrospinal fluid (CSF)
- Stroke
- Abscess
- HIV and AIDS
- Infection
- Autoimmune disease
- Drug therapy, such as chemotherapy
- Hereditary diseases
- Other conditions that cause paralysis of the facial nerve
