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

他的失调也有所好转 这个是指...肢体障碍 是的。

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.

这些突变导致脑和脊髓的退行性改变，这会导致进行性协调障碍、平衡障碍等，称为共济失调。

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.

他们通常在大约20年后因呼吸或吞咽问题相关的病因去世。这种疾病被称为脊髓脑性共济失调1型，或简称SCA-1。
