Whether cerebellar atrophy is hereditary depends on the cause of the atrophy. In neurology, there is a disease called spinocerebellar ataxia, which is caused by genetic mutations and results in significant ataxic symptoms. The imaging studies show cerebellar atrophy. This disease can be inherited, so it is important to conduct prenatal counseling to promote eugenics. Cerebellar atrophy caused by other reasons is not hereditary. For example, if the atrophy is due to neurodegenerative disease such as multiple system atrophy, there is no clear genetic tendency. If the atrophy is caused by a cerebellar infarction, it is also not hereditary.
