Gaze evoked nystagmus will increase to the right when you gaze right, and increase to the left when you gaze left.Īll nystagmus can cause dizziness and vertigo, but distinguishing between central and peripheral (vestibular) causes of nystagmus is essential to your treatment. However, central nystagmus can also be gaze-evoked. Central nystagmus will present at rest as down beating, up beating, or pendular nystagmus. These central disorders are usually due to brain stem or cerebellar degeneration or dysfunction. Nystagmus doesn’t only occur due to vestibular disorders, it can also be caused by a central nervous system dysfunction.

Right beating horizontal nystagmus, increasing with right gaze Left Vestibular Neuritis(superior branch) Left beating horizontal nystagmus, increasing with left gaze Right Vestibular Neuritis (superior branch) If you catch these symptoms within the first 24 hours, a prescription for a steroid from your physician will help your long term outcomes. This effect is called Alexander’s Law nystagmus will continue to beat in the same direction, regardless of gaze, but it will increase when your gaze is in the direction of your nystagmus. However, the nystagmus will increase, or become faster, when you look in the direction of the nystagmus. This will present as a horizontal nystagmus that beats away from the affected ear (toward the unaffected year), and will not change direction with the direction of gaze. Acutely, a superior nerve vestibular neuritis (the most common form) will cause spontaneous nystagmus for 12-36 hours.

In some cases, you will need to turn your head or move your eyes, so be sure to listen and keep your eyes open through the duration of your testing unless directed otherwise. We use your nystagmus’ direction to determine the affected ear, canal, and/or nerve that is causing your symptoms. Your healthcare provider, like a physical therapist or physician, will examine your eyes to observe the nystagmus. The nystagmus is the cause of your true spinning vertigo symptoms, which is different from other kinds of dizziness. These include, but are not limited to: Benign Paroxysmal Positional Vertigo (BPPV) Benign Paroxysmal Positional Vertigo (BPPV), Vestibular Neuritis, and Ménière’s Disease. Nystagmus can move in almost any direction, its direction is completely dependent on the diagnosis. Nystagmus is described by the direction it moves toward during the fast phase. The fast phase is the direction the eye is moving, and the slow phase is a resetting saccade to place the eye back in the middle. There are two phases of nystagmus, the fast phase and the slow phase. It is an involuntary, uncontrolled, repetitive eye movement. Nystagmus is a word we use in vestibular rehabilitation very frequently.
