The dissociation between caloric testing and the video head impulse test (vHIT represents a well-recognized but often underutilized phenomenon in clinical vestibulology.
Although both tests assess horizontal semicircular canal function, they probe the vestibulo-ocular reflex under profoundly different stimulation paradigms, allowing selective dysfunction to emerge.
A classical paradigm, reinterpreted through a modern clinical framework.

Scientific focus of the webinar:

• Physiological mechanisms underlying caloric–vHIT dissociation
• Frequency-domain selectivity in vestibular dysfunction
• Reduced caloric responses with preserved vHIT gain in Ménière’s disease
• Central sensory modulation patterns in vestibular migraine
• Diagnostic and phenotypic value in early-stage and borderline cases
• Integrated interpretation for refined clinical stratification
• Implications for future personalized approaches in vestibular medicine

This seminar will provide a clinically rigorous and physiologically grounded framework for interpreting classical vestibular tests within a modern diagnostic paradigm
