Cerebellar atrophy is a type of brain atrophy. Microcephaly is characterized by the inability to walk in a straight line, ataxia with positive closed eyes and a drunkard’s gait, and speech symptoms such as gibberish and explosive speech. After the development of microcephaly, the treatment plan for patients is the same as that for cerebral atrophy. If patients have clinical symptoms, they can be rehabilitated with acupuncture and physiotherapy, massage, and can take oral aspirin and statin drugs. Also if accompanied by dementia and other manifestations, oral donepezil and meperidine can be taken to prevent further aggravation of symptoms. At the same time, patients themselves should control blood pressure, blood sugar, blood lipids and other underlying diseases, improve poor lifestyle, do not smoke and drink, exercise appropriately, strengthen care, and at the same time prevent the occurrence of various complications.
