Vertigo 1. I need to clarify for patients with vertigo, what do you feel when you are “dizzy”? Is it spinning? Or dizziness? Or do you walk unsteadily but have no abnormalities when sitting or lying down? When you are dizzy, do you have clear consciousness, for example, you can feel any external sound or stimulus? 2. 3. I need to know if you had a cold or other discomfort before your dizziness. For example, insomnia? Depressed mood? Exertion? Noise exposure? Trauma? Special diet? Drug application? etc. 4. How many episodes of dizziness have you had since the first one? How long does each dizziness last? Can it be relieved without any treatment? Did you feel any progressive hearing loss during the period of dizziness? When was the last episode of dizziness? How long did it last? 5. What are you doing during each dizziness attack? For example, getting up? Turning over? Lifting heavy objects? Holding your breath? Squatting to upright position? 6. Do you have any past history of motion sickness? Do you have recurrent headache attacks during the day? Do you have any headache attacks that affect your life and work? Do you have any history of recurrent headaches in your family or relatives? Do you have any photophobia before your vertigo attack? Fear of sound? Do you have any flashing lights in front of your eyes? 7. Is it possible to feel panic in an open or crowded place during the day? Discomfort? Or even vertigo attacks? 8. I need your vestibular function related examination results (nystagmus view, vestibular muscle evoked potential, cochlea electrogram, ABR, glycerol test, etc., whatever you have), hearing examination results, and if you have imaging such as MRI of the head or cervical spine film, please let me know the results.
