Readers, have you ever experienced or know what vertigo is? For example, sudden feeling of spinning, shaking, walking unsteadiness in the peripheral world or yourself without any aura, and sometimes vertigo when you get up, lie down, or turn over. So do you know how painful their vertigo is? The examples of vertigo that we often encounter in our daily life are motion sickness and seasickness, and people who do not experience vertigo can imagine the pain of patients when they see the symptoms of motion sickness. Here I will introduce which diseases the above vertigo belongs to and their respective clinical symptoms: 1. Rotational vertigo: It is mostly caused by the dysfunction of vestibular nervous system and cerebellum, mainly by the feeling of tilting, feeling oneself swaying or rotating scenery. According to its etiology, it can be divided into two categories: peripheral vertigo and central vertigo. (1) Peripheral vertigo: It is the vertigo caused by the lesion of the vagus or vestibular nerve in the inner ear. It is common in Meniere’s disease, vaginitis, drug-related vertigo and vestibular neuritis. (2) Central vertigo: vertigo caused by lesions of the brainstem, cerebellum, brain and spinal cord. It is common in vertebrobasilar artery insufficiency of blood supply, intracranial tumor, intracranial infection, multiple sclerosis, vertigo epilepsy and traumatic vertigo, etc. 2.Postural vertigo: It is the vertigo that occurs when the patient changes his position or moves his head. The symptoms often last for 10-20 seconds. And if the patient keeps one position unchanged, vertigo will not occur. It is a disease characterized by paroxysmal vertigo episodes, which are generally thought to be caused by the compression of the intracranial segment of the vestibular nerve by microvessels, triggering the demyelination of nerve fibers. The diagnosis of this disease should exclude other typical vertigo disorders such as Meniere’s disease, benign paroxysmal positional vertigo, migrainous vertigo, vestibular neuronitis and hemicranial fissure syndrome. This shows that although vertigo is the same, the sensation of vertigo is different and the location of the disease is also different. Therefore, it is very important to tell the doctor accurately about the condition in order to correctly diagnose and treat the disease. For example, we should tell the doctor the specific symptoms of vertigo (whether there is rotation, self or peripheral rotation, and the direction of rotation), the frequency and duration of the attacks, whether there are any triggering factors (whether it is caused by a certain action, what you are doing when the vertigo attacks), whether there are any auditory symptoms (hearing loss in any ear, tinnitus, dullness in the ear), and whether there are other accompanying symptoms (such as vision changes, vocal disorders, difficulty in swallowing, changes in consciousness, etc.). (e.g., difficulty in swallowing, change in consciousness, headache), any underlying physical diseases (e.g., hypertension, hyperglycemia, heart disease), any past headache or motion sickness, any family history of vertigo or headache, etc.
