Last reviewed 03/2023
Positional nystagmus occurs with certain positions of the head and is often accompanied by true rotatory vertigo.
Positional nystagmus associated with a peripheral pathology is usually short-lived and fatiguable unlike that associated with a central pathology which may change in direction and does not fatigue.
Positional nystagmus is seen in:
- benign paroxysmal positional nystagmus
- central - malignant - positional nystagmus
