It's characterized by drooping of the face, difficulty with facial expressions, and potentially other symptoms like drooling, dry eyes, and altered taste.
While the exact cause is often unknown, viral infections are suspected.
Most people recover within a few weeks or months, but some may experience lingering or incomplete recovery.
Symptoms:
- Drooping face: The most noticeable symptom, especially on the affected side of the face.
- Difficulty with facial expressions: Problems smiling, frowning, or making other facial movements.
- Drooling: Uncontrolled saliva flow.
- Dry eyes: Reduced tear production, potentially leading to eye irritation.
- Altered taste: Changes in taste perception, especially on the affected side of the tongue.
- Other potential symptoms: Headache, pain around the ear, sensitivity to sound, and numbness or tingling.
Causes:
- The exact cause of Bell's palsy is often unknown, but inflammation and swelling of the facial nerve are thought to be involved.
- Viral infections, particularly herpes viruses, are frequently implicated, though other potential causes include diabetes, high blood pressure, and pregnancy, according to the Mayo Clinic.
Diagnosis:
- Bell's palsy is usually diagnosed based on symptoms and ruling out other potential causes of facial paralysis.
- A physical exam and neurological assessment are typically sufficient to diagnose the condition.
Treatment:
- Treatment usually involves medications, such as corticosteroids, to reduce inflammation and improve recovery.
- Eye care, including artificial tears and sunglasses, may be necessary to protect the eye on the affected side.
- In some cases, physical therapy or other supportive therapies may be recommended.
Outlook:
- Most people with Bell's palsy recover within a few weeks or months, with full or near-full restoration of facial function.
- However, some individuals may experience lingering or incomplete recovery.
- In rare cases, facial paralysis may be permanent.
