My mom has a shrunken cerebellum shown by the MRI scanning. she has a gait but walks almost fine when stressing her legs. She has had the unbalanced issue slightly from 5 years ago and has become more unbalanced now. She has no other symptoms like slurred speech, rapid eye movements or hand tremors. She says she feels a little weak in her right hand though. My questions are, how much worse will they get. My mom thinks it's due to vitamin E deficiency but the doctor thinks it's SCA. If it's SCA, I have a 50% chance of getting it and I don't know if it's the nerves, but my legs feel a little weird and tingly. I might be experiencing anxiety but I don't know.
What are the initial symptoms?
What should I look out for since it's heridatary?
