Presbyvestibulopathy (PVP)

Article Summary

Dizziness is complicated and often has many different causes. Presbyvestibulopathy is one type of vestibular disorder that occurs with aging and may be a cause of such symptoms for many individuals. Studies demonstrate that age-related breakdown of cells in the vestibular system can cause dizziness, imbalance, and other symptoms of PVP.

Presbyvestibulopathy (PVP)

Case presentation

JS is a 75-year-old male presenting with progressive imbalance. He first noticed symptoms five years ago and has had three falls while walking on uneven surfaces without significant injury. He previously led an active lifestyle as a college athlete, and he walked and hiked regularly throughout adulthood. However, these activities have become rarer in the last decade, and in the last few years his wife reports that he rarely leaves the house. He says that he has become apprehensive about using the stairs and walking without the lights on. He can drive during the day but is uncomfortable doing so at night. He has a history of hypertension that he takes medications for but has no other medical problems. He appears dejected and asks, “What is happening to me?”

What is presbyvestibulopathy (PVP)?

Dizziness is complicated and often has many different causes. Presbyvestibulopathy is one type of vestibular disorder that occurs with aging and may be a cause of such symptoms for many individuals.

Presbyvestibulopathy (PVP), also known as presbyvertigo, is the age-related functional decline of the vestibular organs in the inner ear, known as the semicircular canals, utricle, and saccule. It is thought to be due to accumulated insults (infection, inflammation, poor cardiovascular health, medications, and/or trauma) and genetic predisposition over the course of a person’s life. Consequences of untreated PVP include limited mobility, increasing fall-risk, social isolation, and significantly decreased quality of life (Agrawal et al, 2018).

How common is presbyvestibulopathy?

By 2050, the worldwide population of individuals aged 60 years and older will exceed two billion. In the US, nearly 20% of individuals aged 65 years and older report dizziness or balance problems in the past year (Lin, 2012), while 85% of individuals aged 80 years and older experience balance dysfunction (Agrawal et al, 2009). Such problems have been shown to significantly decrease quality of life, impacting speech, emotion, cognition, and memory. In addition, many patients associate fear and anxiety with their imbalance, leading to limited mobility and social isolation (Harun, 2016). The resulting aggregate economic burden is $227 billion among individuals aged 60 years and older (Agrawal et al, 2018).

Why does presbyvestibulopathy occur in aging individuals?

Studies demonstrate that age-related breakdown of cells in the vestibular system can cause dizziness, imbalance, and other symptoms of PVP.

The sensory cells of the inner ear, called hair cells, slowly degenerate with age, as do the neurons that transmit information from the hair cells to the brain, including vestibular nerve fibers, ganglion cells, and cerebellar nuclei. This degeneration is similar to what happens in the cochlea (the hearing organ) in presbycusis, or age-related hearing loss.

These findings are supported by vestibular testing in people, which shows a decline in function, mostly in the semicircular canals, then the saccule, and minimally affecting the utricle (Zalewski, 2015). Vestibular tests might even underestimate this decline since they use mild stimuli, which may not adequately detect vestibular dysfunction because of the brain’s ability to adapt and compensate, which can hide vestibular decline (Paige, 1992).

Balance is a complex brain function that requires the integration of input from multiple sensory systems such as vision, proprioception (spatial sensors in our feet and spine), and the vestibular organs of the inner ear. When there is a deficiency in the functioning of the inner ear, your eyes and muscles compensate. The older one becomes, however, the more likely there is to be decline in all three of these systems, reducing the brain’s ability to compensate for vestibular loss. Reduced sensation, vision acuity, and muscle strength all contribute to the brain’s diminished ability to integrate signals from these different systems. Many of these sensory and mechanical losses progress slowly and may not be consciously recognized by the patient. Fear of falling is a result of this multisensory decline, which in turn contributes to anxiety, causing the patient to avoid situations they feel could cause them to fall, which in turn results in a positive feedback loop (i.e. more fear of falling).

How is presbyvestibulopathy diagnosed?

Dizziness in the geriatric population often involves many factors, requiring careful consideration of the patient’s medical history. Often, your physician will start their evaluation by ruling out other common causes of dizziness, such as medication side-effects. Medications that lower blood pressure or affect the nervous system are the most common offenders. In such cases, your physician may ask you to consider alternatives to medications that may cause or make dizziness worse.

Why is presbyvestibulopathy underdiagnosed and undertreated?

Age-related hearing loss, or presbycusis, is often diagnosed with a quantitative hearing test, known as pure-tone audiometry. This is a relatively simple diagnostic test that can be performed quickly and interpreted by a trained healthcare professional.

Unlike pure-tone audiometry, vestibular testing is indirect, time-consuming, and difficult to perform accurately. There is no single quantifiable measurement of balance. Assessment of the vestibular system is accomplished through indirect testing of reflexes. These reflexes include the vestibulocular (VOR) and vestibular spinal reflexes. Standard tests that evaluate the VOR include videonystagmography (VNG), rotational vestibular testing, ocular vestibular evoked myogenic potentials (oVEMPs), and video head impulse testing (vHIT). Similarly, the vestibular spinal reflex is evaluated using computerized dynamic platform posturography (CDP) and cervical vestibular evoked myogenic potentials (cVEMPs). Unlike audiograms, vestibular testing results do not provide a single quantifiable measurement of vestibular function. These tests also require a lot of specialized equipment and a trained professional to perform, which limits access for many people. For example, in Europe, more than 60% of vestibular physical therapists report no vestibular function testing equipment at their workplace (Meldrum et al 2020).

How is presbyvestibulopathy treated?

Vestibular rehabilitation (VR) with a physical therapist is the primary treatment approach. The goal of VR is to retrain the brain to recognize and process signals from the vestibular system and coordinate them with information from vision and muscles, while also addressing psychological problems such as anxiety and panic (Dunlap et al, 2019). Once diagnosed, it can take many months for patients to see improvement.

It may be necessary to take fall precautions, especially if dizziness is affecting your gait. Precautions include wearing appropriate shoes, removing hazards from the home, and using assistive mobility devices. Check out these articles on fall prevention and safety-proofing your home.

Your physician may also refer you to an ophthalmologist (eye doctor) if you are having issues with your sight, or a geriatrician or psychiatrist for help with mood or anxiety problems.

At this time, there are no pharmacological drugs or surgical procedures that have been shown to help patients with PVP.

On the distant horizon, there are studies to develop a vestibular implant that would replace lost vestibular hair cells (Johns Hopkins University, NCT02725463).
