In clinical practice, if a patient suddenly becomes dizzy and cannot stand to collapse, the following possibilities need to be considered: First, if the patient is dizzy and cannot stand, and accompanied by visual rotation, accompanied by tinnitus, ear swelling and other discomfort symptoms, otogenic diseases, such as Meniere’s disease causing the above discomfort, need to be considered. If this is the case, it is recommended that the patient can take betahistine orally, two tablets once, three times a day, as well as intravenous injection of small doses of hormone therapy, and the above discomfort will be relieved; second, it is also necessary to consider acute cerebrovascular accidents, such as infarction or bleeding of the cerebellum and brainstem caused by the above discomfort. If this is the latter case, you must go to the hospital to see a neurologist and perform a cranial CT and MRI examination to further clarify the diagnosis.
