Which type of nystagmus is more associated with a vertical component?

Explanation:
Vertical components in nystagmus point to central, pathological processes rather than benign horizontal types. Central dysfunction in the brainstem or cerebellum can produce vertical eye movements in nystagmus, such as upbeat or downbeat forms, which are hallmark examples of pathological nystagmus. In contrast, end-point and horizontal gaze-evoked nystagmus are typically horizontal and linked to peripheral or non-central mechanisms. So when a vertical component is present, it best fits pathological nystagmus.
