Cerebellar atrophy is not Alzheimer’s disease, cerebellar atrophy refers to atrophy of the cerebellum. The main function of the cerebellum is to manage the coordination and balance of the human body, and people with cerebellar atrophy walk less steadily and move in an uncoordinated manner, which is mainly a phenomenon in this regard, while memory and intelligence are normal in all aspects. Alzheimer’s disease mainly refers to cerebral atrophy, and patients will show a decline in memory and attention, a decline in calculation, inference and judgment, and a decline in the patient’s daily life ability. Some patients experience psychiatric symptoms, such as hallucinations, as well as anxiety, depression, and sleep disorders. Therefore, cerebellar atrophy and Alzheimer’s disease are two completely different concepts, cerebellar atrophy must go to the neurology department of a regular hospital.
