[Position nystagmus (author's transl)].

Detailed research about the positioning nystagmus show important and characteristic qualities. Now and then, nystagmus qualities permit a differential diagnosis of the diseased organ (peripheral versus central). In general, the peripheral paroxysmal benign nystagmus is proceeded by a short latency, showing mainly a rotatory component towards the inferiorly positioned labyrinth. A paroxysmal pattern is typical as compared to the central position nystagmus.
