Abstract: The patient in this case is a 52-year-old female who has been suffering from motion sickness since childhood, so she has never taken it seriously and considered it to be genetically related. 1 week ago, the patient presented to our hospital with severe motion sickness, nausea, vomiting, and vertigo that was evident for 1 week and did not completely improve. After completing relevant tests, motion sickness (motion sickness) and vestibular hypofunction were finally confirmed, and medication + rehabilitation treatment was given to stabilize the condition and improve the motion sickness symptoms. [Basic information] Female, 52 years old [Disease type] Motion sickness, vestibular hypofunction [Hospital] Shandong Provincial Third Hospital [Consultation date] May 2019 [Treatment plan] Medication (Ginkgo biloba extract tablets, betahistine mesylate tablets, powerful vertigo tablets) + rehabilitation training (vestibular function training exercises) [Treatment cycle] Outpatient treatment, outpatient follow-up after 1 week, telephone follow-up after half a month [Treatment effect]. Treatment effect】Stable condition and improvement of motion sickness I. Initial consultation The patient has been suffering from motion sickness since she was a child, and she is usually afraid to take a car, and usually rides a bicycle to and from work. 1 week ago, due to the hot weather, her child drove her to the shopping mall for a dinner party, and in just 20 minutes, the patient developed severe motion sickness, nausea, vomiting and vertigo, which lasted for 1 week and did not improve completely. dizzy, walking unsteadily, like a boat ride, with no previous history of specific diseases. On neurological examination, the closed-eye difficult-to-stand sign was positive, and the rest of the signs were not significantly positive. The patient was diagnosed with motion sickness in the outpatient clinic and further improvement of vestibular function examination was recommended to exclude organic lesions. The patient was examined in the outpatient clinic, including routine blood tests, liver function, renal function, lipids, blood glucose, and cardiac enzymes, and was found to have mild anemia and low sodium. No other significant abnormalities were found. The cranial magnetic resonance examination was improved, and no significant abnormalities were found in the cranial magnetic resonance examination to exclude cerebellar diseases. Vestibular function examination was completed to clarify the presence or absence of vestibular dysfunction, and vestibular function examination suggested mild to moderate vestibular semicircular canal hypofunction. After hospitalization, anti-dizziness medication was given, mainly including betahistine mesylate tablets and powerful vertigo tablets. The patient was advised to perform balance training and vestibular function training exercises. He also talked to the patient in detail about how to perform the operation, and the patient expressed his understanding and actively cooperated with the treatment, and was advised to follow up with the outpatient clinic in 1 week. （The clinical diagnosis of motion sickness is motion sickness, which is generally related to the vestibule, the body’s balance organ. The patient had motion sickness since childhood, and combined with the vestibular function test results, she was considered to have congenital vestibular hypoplasia and motion sickness caused by low vestibular function. The dizziness symptoms were significantly relieved on the second day and did not reappear on the third day. After 1 week of outpatient follow-up, the patient showed no significant abnormalities and no dizziness symptoms. Half a month later, the patient’s condition was stable and her dizziness symptoms had improved by telephone follow-up. IV. Precautions We are glad that the patient’s symptoms have improved after treatment, but since motion sickness is related to the balance organs of the human inner ear, if the vestibular function balance disorder is caused by congenital development, you should try to avoid the causes that induce dizziness in general, such as looking down at the cell phone, long hours of ambulatory work, staying up late, exertion, long hours of sitting in a car, etc. Avoid emotional anxiety, avoid being in a confined environment for a long time, develop good habits and ensure enough sleep. In daily life, pay attention to not eating too much before riding in a car, pay attention to opening windows for ventilation, or take motion sickness medication in advance, or reduce the occurrence of motion sickness by distraction. During the medication period, pay attention to the medication on time and pay attention to whether the symptoms of dizziness improve and whether there are other symptoms such as panic, chest tightness, palpitations, nausea, vomiting, etc. If necessary, go to the hospital for further consultation as early as possible. V. Personal insight Motion sickness is very common and seen in different age groups. Many people around us suffer from motion sickness, for example, the elderly and children may experience motion sickness, and normal people may also experience motion sickness under extreme exertion. If there are severe symptoms of motion sickness, for example, if the patient’s discomfort persists for 1 week without relief, he or she should go to the hospital as soon as possible to further improve the examination to clarify whether there is an organic lesion that requires further treatment, and the doctor should actively improve the cranial and vestibular function-related examination in the process of treating patients with severe motion sickness to avoid the possibility of missing the diagnosis.
