Dizziness for three days, if the onset of the patient is related to mental tension and exertion, with heavy dizziness symptoms, accompanied by visual rotation, deafness and tinnitus, may be due to Meniere’s syndrome. Patients with Meniere’s syndrome are mainly treated symptomatically, they can take oral dizziness stop, pethidine, or if the effect is not good, they can also inject Benadryl intramuscularly. If the patient has a history of cold before the disease, and the dizziness is accompanied by visual rotation, without deafness or tinnitus, it may be caused by vestibular neuronitis, and the treatment of this disease is mainly symptomatic anti-dizziness treatment along with antiviral treatment. If the patient has mild symptoms of dizziness with balance and ataxia, without deafness, tinnitus and visual rotation, it may be a deficiency of blood supply to the vertebrobasilar system. In case of insufficient blood supply to the vertebrobasilar system, patients generally present with cerebellar and brainstem ischemia and hypoxia, and may present with dizziness, nausea, balance disorders and ataxia. Cranial CT examinations are usually normal, and cranial MRI may show ischemic foci. Patients usually occur in middle-aged and elderly people, and most of them have atherosclerosis, hyperlipidemia and diabetes mellitus, which are mainly treated by improving blood circulation and softening blood vessels. The patient’s blood lipids and blood glucose are also controlled.
