Dizziness, nausea and unsteady walking may be cerebellar lesions, such as cerebellar atrophy patients can appear. It is mostly seen in middle-aged and old people, and the disease starts insidiously and progresses gradually after the onset of the disease, and there is no effective treatment method at present. There are many clinical reasons for this disease: for example, chronic cerebral blood supply insufficiency can occur. If patients drink a lot of alcohol for a long time, it is also easy to cause chronic cerebral hypoxia, and its may also occur. In addition, it can also be caused by abnormal blood pressure. For example, it may occur when the blood pressure increases or decreases, mainly due to high blood pressure causing vasospasm and resulting in cerebral ischemia and hypoxia. If the blood pressure is too low, it may cause hypoperfusion of the brain, which also tends to cause ischemia and hypoxia of the brain, and thus may cause the above symptoms. It may also be due to vascular diseases of the brain, such as cerebellar and brainstem hemorrhage and infarction may also be present in patients, and cranial MRI may be examined to clarify the diagnosis if necessary.
