7.And he's made modest improvement in his ataxia, which is loss of -- Loss of body movement. Yes.

他运动失调也有所好转 这个是指...肢体运动障碍 是。

8.These mutations result in degenerative changes in the cerebellum and often in the spinal cord which causes progressive problems with coordination and balance known as ataxia.

这些突变导致小脑和脊髓退改变，这会导致运动协调障碍、平衡障碍等，称为共济失调。

9.They typically die around 20 years later, of causes related to breathing or swallowing problems. The disorder is known as spino-cerebellar ataxia type 1, or SCA-1.
