Walking crookedly to one side may be a balance disorder, mostly seen in lesions of the cerebellum. Patients may present with cerebellar atrophy, for example, and they may also experience memory loss, inattention, and possibly intention tremor. In general, patients have a chronic onset, mostly in the elderly, and most are considered to be a degenerative disease for which there is no specific treatment. Early applications of olanzapine and piracetam may slow down the progression of the patient’s disease. It may also be caused by cerebrovascular disease, such as cerebellar infarction or cerebellar hemorrhage, and can occur in patients with cerebellar infarction. Cerebellar infarction, which usually starts in the quiet state or during sleep, is a hypointense lesion on cranial CT. Cerebellar hemorrhage usually starts during activity and is seen as a high-density lesion on cranial CT. Most patients have a previous history of hyperlipidemia, hypertension, and diabetes mellitus and should be hospitalized promptly after onset for comprehensive treatment. It may also be a posterior circulation transient ischemic attack. Most of the general symptoms in this patient last from 10-15 minutes and rarely exceed 1 hour, and the cranial CT examination is normal. It may also progress to cerebral infarction if it occurs repeatedly. Treatment should be given clinically, mainly oral aspirin anti-platelet aggregation therapy. Drugs to improve blood circulation can also be applied. Clinically, Danshen, Panax notoginseng and Ginkgo biloba drops are usually applied, etc.
