title: [Idiopathic and zoster vestibular neuritis. Course and prognosis].
abstract: 112 cases of vestibular neuritis were studied. 77% were relatively pure lesions, whilst in 23% of cases there were more extensive lesions with abnormalities of the saccadic oculomotor system and BERA abnormalities. Spontaneous nystagmus disappeared in 2 to 3 months in general. In 54% of cases there was complete recovery of absolute reflex activity within normal limits on the affected side. There was restoration of normal difference of reflectivity in 22%. In 13% there was normal absolute reflex activity, normal hypovalence and normal directional preponderance. Age appeared to influence the course of directional preponderance and the extent of lesions on the course of hypovalence. Early mobilisation of the patient is of primordial importance.
