People get older.
Do you know this vestibular disorder that hits older people? Until today almost no one ever heard of it.
We are talking about #Presbyvestibulopathy (PVP). Sometimes it's also called #Presbyvertigo.
In this article - I already shared it with you in April on Facebook... aren't we early ? - I summarize it for you in easy language. On September 26 the scientific article was published in Journal of Vestibular Research.
Amongst the authors: Floris Wuyts and Margaret Sharpe!
When can we speak of PVP?
1. First of all when it's a chronic vestibular disorder, presenting at least 2 of these 4 symptoms:
* Postural imbalance or insteadiness (which can be rather when standing still, or rather dynamic: for example when standing up or throwing a ball)
* Gait disturbance
* Chronic dizziness
* Reccurent falls
2. When there's a mild hypofunction in between normal vestibular function and the level of vestibular loss associated with BVP or Bilateral Vestibulopathy.
3. PVP is age related:
We are talking about people aged 60+. At 60+ we encounter some sensory & functional losses. So PVP typically occurs along with other age-related deficits of vision, proprioception, and/or cortical, cerebellar and extrapyramidal function.
And, as this is a 60+ disorder, we see a degradation of the vestibular end-organ structure, with
* Decline of vestibular hair cell populations (starting at 50+)
* A degeneration of the sacculus / utriculus otoconia
* A decline of vestibular nerve fibre
4. There's no other vestibular disorder to be diagnosed
Take a look at this very interesting differential diagnosis table for PVP (source www.jvr-web.org) and its distinction with other disorders! The full info and diagnostic criteria was first to be found in this Consensus document of the Classification Committee of the Bárány Society with Wuyts as one of the Subcommittee members. Since September 26 it is published in Journal of Vestibular Research.
We hope that this article was useful for you! Take it with you if you need to go to the hospital with an older family member who suffers from gait disturbance, postural imbalance, chronic dizziness and/or recurrent falls.
