| At 6 years of age, she has cerebellar signs, which include gait ataxia, peripheral ataxia with dysdiadochokinesia, dysmetria, and titubation. |
| The dorsal vermis and underlying fastigial nucleus are important in controlling saccadic amplitude and lesions here cause saccadic dysmetria. |
| No dysmetria was noted on the finger-to-nose test, but heel or toe gait was impaired. |
| After 2 weeks, the animal showed severe dysmetria of the extremities without obvious myoclonia. |
| An intention tremor was present with dysmetria and dysdiadochokinesia, especially on the left. |
| On examination at 4 years of age, she has a broad-based gait with tremors, head titubation, dysmetria, and dysdiadochokinesia. |
