Some people who wake up suddenly feeling spinning in the sky often consider the possibility of acute vestibular syndrome, mostly caused by dislocation of the otolith in the inner ear, also known as positional vertigo, which belongs to the most common kind. There is also a part of it due to cerebrovascular disease. Some people have unstable walking and even unfavorable speech, so they should be highly alert to cerebrovascular disease, such as brain stem and cerebellar infarction, brain stem and cerebellar hemorrhage, which can be accompanied by nausea and vomiting. Some people wake up from sleep with spinning in the sky, accompanied by tinnitus, which may be Meniere’s disease. Ménière’s disease is caused by fluid accumulation in the labyrinth of the inner ear, which affects balance. Others are due to inflammation, such as inflammation of the vestibular nerve, which governs balance, and can cause the spinning dizziness. Whether it is positional vertigo, inflammation of the vestibular nerve, or Meniere’s disease, it is important to visit a hospital. Especially if it is caused by cerebrovascular disease, it is important to seek medical treatment in time to avoid more serious consequences. If it is positional vertigo, it can be treated by repositioning. If it is caused by Ménière’s disease, symptomatic treatment can be given, and vestibular neuritis can also be controlled by anti-inflammatory treatment.
