Dysdiadochokinesia, for example, is the inability to perform rapid, alternating movements. Dysmetria is the inability to control the range of motion.

Finally, dysarthria is the inability to correctly enunciate words. Words and phrases tend to be slurred together or improperly constructed and used. Besides ataxia, there are other signs of cerebellar damage and injury. For instance, nystagmus is a condition where the individual loses eye control. Their eyes rapidly oscillate in a horizontal, vertical, or rotary direction. Another indication of cerebellar damage and injury is hypotonia, where muscle tone is lost. Scanning speech, unlike some of the other forms of cerebellar damage and injury, causes the individual to speak very slowly. There is also a high probability that the individual will hesitate at the
