Ans: Vertigo can be diagnosed by your GP who would ask you a few questions and carry out a few tests. Some of the tests include:Physical Examination - This includes looking inside your ear or checking your eyes to look for signs of uncontrolled movement. Your GP could also try to recreate your condition or check your balance by asking you to go quickly from sitting to lying position.Hearing Tests - A number of ear tests like audiometry tests, tuning fork tests can be performed if the patient complains of hearing loss or ringing in the ear. Videonystagmography - VNG or Videonystagmography is a procedure that looks into signs of nystagmus in the eye in a more detailed manner. Scans - A scan of the head may reveal the cause of vertigo such as a non-cancerous brain tumour (also called acoustic neuroma).
