Can cause:
- Equilibrium
- Nystagmus (Rapid, repetitive eye movement)
1.Horizontal nystagmus (involve side to side eye movement)
- Vertical nystagmus
(Cause up and down movement)
- Rotary nystagmus
(circular eye movement)
-
Can cause:
- Truncal ataxia
- Dysmetria (inability to control the distance, speed, and range of motion necessary to perform smoothly coordinated movements).
- Dysdiadochokinesia (Difficulty to make movements exhibiting a rapid change of motion).
- Dysarthria ( Difficulty in speech due to weakness of speech muscles).
