DIZZINESS DIAGNOSIS |
|
|
During the initial medical examination,
an individual with dizziness should provide a detailed description
of the type of dizziness experienced, when it occurs, and how often
each episode lasts. A diary of symptoms may help track this
information. Report any symptoms that accompany the dizziness, such
as a ringing in the ear or nausea, any recent injury or infection,
and any medication taken.
Blood pressure, pulse, respiration, and body temperature are
checked, and the ear, nose, and throat are scrutinized. The sense of
balance is assessed by moving the individual's head to various
positions or by tilt-table testing. In tilt-table testing, the
person lies on a table that can be shifted into different positions
and reports any dizziness that occurs.
Further tests may be indicated by the initial examination. Hearing
tests help assess ear damage. X rays, magnetic resonance imaging
(MRI) can pinpoint evidence of nerve damage, tumor, or other
structural problems. If a vestibular disorder is suspected, a
technique called electronystagmography (ENG) may be used. ENG
measures the electrical impulses generated by eye movements. Blood
tests can determine diabetes, high cholesterol, and other diseases.
In some cases, a heart evaluation may be useful. Despite thorough
testing, an underlying cause cannot always be determined. |
