Hello, everyone. Today's topic is cerebellar atrophy. Cerebellar atrophy is mainly a manifestation of smaller cerebellar volume or deeper cerebellar cortical sulcus found on imaging. There are many reasons for cerebellar atrophy: 1. It is caused by some primary diseases, such as some congenital or hereditary diseases, mainly including multiple sclerosis, multiple system atrophy, spinocerebellar ataxia, hereditary cerebellar ataxia and other congenital or hereditary diseases. In addition, there are some acquired diseases, such as cerebellar vascular diseases, such as cerebellar hemorrhage, cerebellar atrophy after cerebellar infarction repair. 2. Idiopathic inflammation. For example, some demyelinating changes in the cerebellum caused by brainstem encephalitis, multiple sclerosis and other diseases will eventually lead to some useless cerebellar atrophy when recovering. 3. Cerebellar atrophy caused by drugs, which is common in antiepileptic drugs such as phenytoin, can lead to irreversible cerebellar atrophy when taken for a long time, Therefore, the causes of atrophy are complex and diverse.
