Vertigo is usually caused by the following: 1) dizziness attacks caused by cerebral ischemia, especially ischemia in the basal ganglia region of the brain; 2) dizziness caused by insufficient blood supply to the brain due to blood vessel entrapment in the neck; 3) dizziness may be caused by vestibular dysfunction and lymphatic circulation disorder in the inner ear caused by otoliths. Vertigo is an episodic disease that sometimes attacks and gets better quickly. If the sudden attack gets better, it may be a transient ischemic attack that causes a transient local circulatory disorder in the basal ganglia region of the brain. It is possible that the vascular compression of the cervical spine, after the vascular compression of the cervical blood vessels, leads to impaired cerebral circulation, as well as the dysfunction of the inner ear. Regardless of how long the vertigo attack has been, it is recommended to go to the hospital in time to seek treatment, to understand the cause of vertigo and to see if there are other complications in combination, in order to get timely treatment and handling. Sudden vertigo for a few seconds is the same as vertigo for a long time, and should be treated equally.
