Vertigo-associated disorders

The primary symptom is a sensation that you or the room is moving or spinning. With central vertigo, there are usually other symptoms associated with the condition that is causing the vertigo. Associated symptoms include the following:

• Double vision
• Difficulty swallowing
• Facial paralysis
• Slurred speech
• Weakness of the limbs

Nystagmus (involuntary eye movements) and hearing loss may be present in both central and peripheral vertigo. Other signs such as other eye movement abnormalities, lack of coordination, weakness, or sensory loss suggest a central cause.

Tests to determine the cause of vertigo may include the following:

• Head CT
• MRI scan of head and MRA scan of blood vessels of the brain
• Caloric stimulation (tests eye reflexes)
• Electronystagmography
• EEG, evoked auditory potential studies
• Lumbar puncture
• Blood tests
