The reasons for getting up early in the morning and experiencing dizziness and lightheadedness are mainly considered in the following aspects: First, if middle-aged and elderly people have a history of cerebral arteriosclerosis and cerebral stenosis, and the symptoms of dizziness and lightheadedness persist, it is considered that they may be caused by cerebral vasospasm and insufficient blood supply to the brain. If the patient is accompanied by unsteady walking, tilting the body to one side or clumsy speech, it is considered that it may be caused by cerebral infarction or transient ischemic attack or cerebral hemorrhage. Secondly, if there are transient episodes of dizziness during the change of head position early in the morning, it is considered to be caused by otolithiasis. Thirdly, if the dizziness is accompanied by cold sweat, panic and shortness of breath, and these symptoms are accompanied by tinnitus and stuffiness in the ears, it is considered to be caused by Meniere’s disease. If there is no tinnitus or stuffiness in the ears, it may be caused by vestibular neuron inflammation. Most patients with vestibular neuron inflammation have a history of upper respiratory tract infections within 2 weeks prior to the onset of the disease.
