There are very many causes of vertigo, and common ear diseases, neurological diseases and cervical spondylosis can lead to vertigo symptoms. Due to different causes and different treatments, if patients have recurrent episodes of vertigo, they should seek medical attention for corresponding treatment in time. I. Ear diseases 1. Otoliths: the otoliths in the inner ear are dislodged into the semicircular canal with the change of body position, stimulating the vestibular semicircular canal and causing vertigo, which is the most common cause of vertigo; 2. Meniere’s disease: vertigo attacks are caused by water accumulation in the membrane vagus, usually accompanied by tinnitus, deafness and a sense of ear stuffiness. 2. Neurological diseases 1. Vestibular neuronitis: sudden vertigo disease caused by the involvement of vestibular neurons, manifested as vertigo with spontaneous nystagmus, which can be accompanied by nausea and vomiting in severe cases; 2. Cerebrovascular disease: refers to various diseases of blood vessels in the brain, including cerebral atherosclerosis, cerebral arteritis, cerebral artery injury, cerebral aneurysm, and cerebral vascular malformation, stenosis, occlusion, thrombosis, etc., which can cause vertigo in patients; 3. Auditory neuroma: a tumor originating from the auditory nerve sheath, which is benign and manifests as tinnitus, vertigo, deafness, facial muscle twitching, ataxia, dysphagia, headache, edema, etc. Cervical spondylosis 1. compression of vertebral artery: the vertebral artery is compressed by bone spur and becomes narrowed or occluded, which leads to vertigo, such as vertebral artery type cervical spondylosis; 2. stimulation of cervical sympathetic nerve: stimulation of sympathetic nerve often involves vertebral artery, which leads to abnormal diastolic function of vertebral artery and easily causes vertigo when vertebral artery spasms, such as sympathetic nerve type cervical spondylosis. Other system diseases can sometimes cause vertigo, such as ophthalmogenic vertigo caused by glaucoma, high or low blood pressure, electrolyte disorders, neurosis, etc. can cause atypical vertigo.
