Dizzy patients feel lightheaded at the onset of dizziness. Dizziness is usually not part of vertigo, and its causes are often anemia, poor sleep, stress, lack of blood supply to the brain, cervical spondylosis, physical weakness, cardiovascular disease, hyperlipidemia, high myopia, etc. It can involve multiple disciplines and is often accompanied by other symptoms. The onset of vertigo patients feel that the sky is spinning, and they can also feel the surrounding scenery swinging from side to side or floating up and down, called vertigo, which is an illusion of motion of themselves or surrounding objects caused by the illusion of spatial orientation. If you feel that you are spinning in space (called subjective vertigo) or that things around you are spinning around you (called objective vertigo), it is often accompanied by a loss of balance. It is a manifestation of a lesion of the vestibular balance system, and damage to the vestibular balance system must be present. Vertigo is subdivided into peripheral vestibular vertigo and central vestibular vertigo. The peripheral vestibular vertigo includes benign episodic positional vertigo (the first cause of vertigo), Meniere’s disease, vestibular neuronitis, etc. Central vertigo refers to vertigo caused by lesions in the central part of the vestibular system, including lesions that violate the central part of the vestibular system for various reasons such as vascular disease, inflammation, tumors, trauma, etc.
