Benign Paroxysmal Positional Vertigo (BPPV) is one of the main causes of positional vertigo, but its mechanisms remain somewhat mysterious. Between pathophysiology, differential diagnoses, and therapeutic innovations, numerous scientific advances now allow us to refine our understanding and improve patient care. Through this conference, we will explore recent discoveries, new therapeutic approaches, open questions, and patient empowerment perspectives.

We invite you to attend our conference to better understand and treat BPPV with updated data and enriching exchanges!

This event is conducted in collaboration with the REHAZENTER and the VERTIGO CLINIC of CHEM.

Program
- WELCOME ADDRESS
Dr José Pereira (Rehazenter) and Dr Alexandre Bisdorff (CHEM)

- THE PATHOPHYSIOLOGY OF BPPV
Dr Marc Hippert, ENT, Vertigo Clinic CHEM

Apart from head trauma and vestibular neuritis, the cause of BPPV remains obscure. What is the state of knowledge on pathophysiology, and what are the gaps in our understanding?

- HOW MANY VARIANTS EXIST?
Dr Gaelle Ngonga, neurologist, Vertigo Clinic CHEM

The most common variants are canalithiasis of the posterior semicircular canal, followed by canalithiasis of the lateral canal, but there are more. Which variants are currently well identified or still theoretical?

- WHAT ARE THE PERIPHERAL AND CENTRAL DIFFERENTIAL DIAGNOSES?
Dr Alexandre Bisdorff, neurologist, Vertigo Clinic CHEM

BPPV is certainly the most common cause of positional vertigo, but not the only one.

Recognizing other differential diagnoses or at least questioning in cases of persistence after multiple maneuvers is important.

- NEW DEVELOPMENTS IN LIBERATORY MANEUVERS
Arnould Vincent and Khosroo Pishvaie, physiotherapists at Rehazenter

The Semont and Epley maneuvers are well established, but there is a multitude of other maneuvers for other canals and rarer BPPV variants. Recently, new methods or complements to existing methods have been proposed.

- POST-MANEUVER RESTRICTIONS, USEFUL OR NOT?
Clara Dimata, physiotherapist, Belval

Theoretical reasons recommend post-maneuver movement restrictions to reduce the risk that free otoliths maneuvered towards the utricle do not fall back into one of the semicircular canals. But, have studies confirmed the hypothesis and its usefulness?

- RESIDUAL VERTIGO POST-MANEUVER
Dr Jacques Majerus, ENT, Vertigo Clinic CHEM

About 2/3 of patients retain vestibular symptoms post-maneuvers from a day to a few weeks. This phenomenon relates to cases where the release of the semicircular canals has succeeded. What are the supposed or established explanations for this phenomenon?

- CAN RELAPSES BE PREVENTED?
Christelle Franconnet, physiotherapist in Bettembourg

BPPV is a recurrent form of vertigo, with a 50% risk of relapse within 10 years. Are there behavioral or medical risk factors for relapses? Have strategies been identified to prevent relapses?

- WHAT IS THE ROLE OF SELF-MANEUVERS?
Elodie Reyter, physiotherapist at Esch-sur-Alzette

Since the risk of relapse is high and some patients experience multiple relapses, learning to self-treat may be an option. What are the arguments for or against?
