Almost everyone has experienced dizziness at one time or another, but each person may have a different connotation when they use the word dizziness to describe it. What is the clinical definition of dizziness? The earliest elaboration is found in a 1972 article in Neurology, which divided dizziness into four categories: vertigo, disequilibrium, imbalance, pro-syncope, and lightheadedness. lightheadedness); in 2009 the Journal of vestibular research redefined vestibular symptoms as vertigo, dizziness, vestibular-visual symptoms and postural symptoms. At this point, the layman must have become dizzy. What are the symptoms of dizziness in layman’s terms? Dizziness 1.1 Rotation of visual objects: the patient feels that the external static objects are in motion; 1.2 Rotation of self: the patient feels that he/she is in motion; 1.3 Both self and external objects are in motion; Dizziness Broad sense: dizziness, pre-syncope (immediately losing consciousness to faint), weakness, fatigue, discomfort and other non-specific sensations; Narrow sense: spatial disorientation, inability to orient oneself; Balance disorder Unstable, unbalanced, swaying, floating or tilting sensations in sitting, standing or walking , floating or tipping sensations. More generally, what does the dizziness that patients often complain of look like? ”Doctor, I feel like the house is spinning”, “Doctor, I feel like the ceiling and the lights are spinning”, “Doctor, I feel like I’m spinning with the bed”, ” Doctor, I feel like I’m falling into an abyss”, “Doctor, I feel like I’m spinning on an axis in the middle of my body”, “Doctor, the words on the screen in front of me are running to the side”… … I often see patients in my office with complaints so bizarre that many doctors tell them it’s a psychological problem, but it turns out to be a vestibular lesion. Listen to these seemingly “neurotic” complaints: “Doctor, I think there is a scale in my head, it is unbalanced, one side is sinking and the other is light”, “Doctor, I think at some point there was a cloud of smoke in my head. I feel like I’m rippling in a stream” …… Are so many dizzy spells related to ENT? Yes, except for non-specific chronic dizziness, fatigue, discomfort and unconscious fainting that are not associated with ENT, all other symptoms may be due to peripheral vestibular lesions and are preferred to be examined and treated at ENT.
