Cerebellar atrophy is difficult to cure. There are many causes of cerebellar atrophy, such as degenerative diseases of the nervous system. For example, olivopontocerebellar atrophy, which is caused by a disease with an unknown pathogenesis leading to the death of cerebellar cells and resulting in atrophy, currently lacks effective treatment methods and is incurable. Some cases are due to hereditary diseases, such as spinocerebellar ataxia, where patients also suffer from cerebellar atrophy, making it very difficult to cure. In addition, some patients who have been chronically drinking alcohol can also develop cerebellar atrophy due to alcohol poisoning. Although clinical symptoms can be significantly improved by discontinuing alcohol use and administering large amounts of vitamin B1 and B12, the atrophy in the cerebellum cannot be reversed as seen on imaging studies.
