Vestibular hypofunction means partial or complete permanent damage to the peripheral vestibular system, or inner ear, which can result from trauma, infection, or lack of adequate blood flow in the inner ear.

This permanent damage can range from 1% to 100%. Vestibular hypofunction that equals a 100% loss is referred to as a “complete vestibular loss” in one or both ears.

The cardiovascular risk factors of high blood pressure, high cholesterol, and diabetes increase the risk of vestibular hypofunction.

Vestibular hypofunction can be a result of certain ototoxic medications that can damage the inner ear.
If a person had a previous bacterial or viral infection in their inner ear, which is called vestibular neuritis or vestibular labyrinthitis, they may or may not have sustained permanent damage causing a vestibular hypofunction.

The resulting vestibular hypofunction from any of the causes listed above may be present, but not noticeable, when a person is younger.

Symptoms of a vestibular hypofunction may present as a dizziness, motion-activated vertigo, balance problems, blurry vision with quick head turns, or unexplained falls later in life.

The symptoms that show up later in life may be due to normal changes to vision with aging, onset of visual pathology, peripheral neuropathy, presbyastasis, or vestibular decompensation after a period of immobility, or relative inactivity, such as in the hospital, during an episode of depression or illness, or after surgery.

Vestibular rehabilitation is shown to be effective for resolving complaints related to vestibular hypofunction.
