The following is a list of symptoms that someone with SCA might experience:

1. Speech impairment: difficulty in speaking clearly and smoothly, especially when trying to pronounce consonants (dysarthria)
2. Difficulty hearing
2. Disease could affect the spine and cause the patient to slouch
3. Short and sponteneous spasms of movement
4. Inability to coordinate legs, especially when trying to walk (this comes hand in hand with inability to control other movements in the body such as hand movements)
6. Loss of balance, frequent falling
7. Uncoordinated eye movements (nystagmus is uncontrolled, rapid eye movements)
8. Clumsiness
9. Rapid weight loss, muscles shrink and lose strength
10. Could lead to paralysis
11. Constant shaking in hands
12. Dizziness
13. Problems swallowing food (often choking)

Furthermore, there might be "side effects" of having SCA, such as depression which is not directly linked to the disease itself, but will also have a big impact on a person.

Although this list will probably freak some people out, not all of these symptoms will appear at the same time. As I talked about in my previous post, SCA is a gradual disease and it might take several years after the onset of the disease for some symptoms to even show.

One good thing is that the cognitive sense of an SCA patient are normal because the area of the brain that controls mental abilities is not affected by SCA.
