What does spinocerebellar ataxia mean?

Spinocerebellar ataxia depends on the understanding of neurogenetic diseases. Neurogenetic diseases are a large class of diseases, which involve single-gene diseases, polygenic diseases, chromatic diseases, etc. However, in the five-year textbooks of neuroscience, because they involve too many aspects, they are specifically single-gene diseases. SCA is one of the few diseases selected. It is an autosomal dominant genetic disease with familial characteristics. In a typical familial disease, one can see the phenomenon of early onset from generation to generation, that is, the next generation of this generation has an earlier onset age. The characteristics of this type of patient are that they will show an unstable walking for no reason, call it ataxia, unstable speech, and sound like a big tongue, and this situation will gradually increase, and both symmetrical limbs will be affected. Even speech is affected, and on careful physical examination it can be judged that he has no obvious acquired organic disorder, such as trauma, which can be ruled out; the cause is indeed caused by periodic cellular mutations brought about by heredity, probably these diseases, and the family history is more certain.
