How is vertigo diagnosed?
The diagnosis of vertigo is made based on the description of what the person is feeling. What is causing the vertigo can be divided into two major categories, peripheral vertigo and central vertigo. Further tests may be needed. For example, a cranial CT scan or cranial MRI may be ordered if a stroke or brain tumor is suspected. A brain stem auditory evoked response test (BAER) may be used to check for a tumor.
Peripheral vertigo, which is much more common, includes benign positional vertigo, labyrinthitis and Ménière's disease. Positional vertigo is diagnosed when moving the head causes the vertigo and returning the head to a neutral position relieves symptoms. Labyrinthitis and Ménière's attacks usually come on abruptly and last for a few hours to a couple of days. There may be intense nausea and vomiting and variable hearing loss. Central vertigo is a more serious problem in the cerebellum (back part of the brain) or brain stem.
