A dysfunction of the vestibular system is commonly characterized by a combination of phenomena involving perceptual, ocular motor, postural, and autonomic manifestations: vertigo/dizziness, nystagmus, ataxia, and nausea. These 4 manifestations correlate with different aspects of vestibular function and emanate from different sites within the central nervous system. The diagnosis of vestibular s...

Background and Purpose: There have been few reports of strokes producing isolated or predominant ocular motor nerve palsies as a clinical manifestation. Methods: We studied seven patients with brain stem stroke who had ocular motor palsies as the only or the predominant neurological manifestation, and we correlated their clinical features with radiological findings. Results: Five patients had s...

If one is to understand the pathophysiology of ocular oscillations it is imperative to distinguish between those involving only the slow system and those that are purely saccadic. Oscillations containing both saccades and slow phases require identification of the causative phase (i.e., that which takes the eyes away from their intended direction) and the corrective phase. Modem methods of recor...
