Vertigo
Diagnosis
To rule out the serious conditions such as cardiovascular
disease, stroke, hemorrhage or tumor, it is important to diagnosis the cause
of vertigo. For the correct diagnosis, the patient must describe in much detail
about their dizziness and how it occurs. The health specialist will ask about
other symptoms and medical problems.
Diagnosis test performed for vertigo may include :
Physical examination of ears and eyes including measuring blood
pressure and heart rate.
Neurological examination also known as Electronystagmography
(ENG) is used to evaluate the vestibular system. It involves testing
hearing in both ears (audiometry tests), testing eye movements, and evaluating
responses to changes in posture and position. During an ENG, the patient sits
in a reclining chair while electrodes are placed on his face and forehead to
track and measure eye movement. Then, the patient is passed through a series
of movements to detect abnormal responses and determine where the problem seems
to be.
Blood tests may include a complete blood count
(CBC) and kidney and thyroid panels to rule out systemic diseases.
Imaging Tests may also perform to brain abnormalities
such as tumors or strokes. Computed tomography (CT scan) produces x-ray images
of the brain and magnetic resonance imaging (MRI scan) uses a magnetic field
to produce detailed images of brain tissue and arteries in the neck and brain.
