Dizziness and vertigo are not the same thing. Dizziness is a feeling of lightheadedness, which can be experienced by patients with high blood pressure at the onset of the disease. People with low blood pressure may feel blackness in front of their eyes or gold stars after squatting for a long time or even fall down, which are called dizziness. The onset of vertigo is a feeling of spinning, accompanied by nausea, vomiting, cold sweat, facial pallor, etc. The symptoms of vertigo are intense during the attack, but the patient is clearly conscious. Clinically, vertigo is divided into central vertigo and peripheral vertigo. Central vertigo is caused by lesions of the brain nerve brain tissue, such as brain trauma, brain tumor, etc.; peripheral vertigo is caused by neck lesions (cervical vertigo) or ear, etc.
