• Bell's Palsy Diagnosis and Tests

Diagnosis and Tests

Bell's Palsy is diagnosed by a physician on basis of clinical symptoms.

  • History taking: Detailed history of symptoms is very important to rule out other similar conditions.
  • Examination: It is conducted by a qualified physician to ascertain extent of paralysis and other symptoms.
  • Tests: There are no particular laboratory tests to determine Bell's Palsy, though specific tests like CT Scan or MRI may be required to rule out other conditions like Stroke.
  • Electromyography (EMG): This test can confirm the presence of nerve damage and determine the severity and the extent of nerve involvement.
  • Differential Diagnosis: It is worthwhile to remember that Bell's Palsy is diagnosed by elimination of other reasonable possibilities like Stroke, Meningitis or any tumors.
