Central vertigo (HiNTs+) & Dix-Hallpike/related examinations (theory) with pearls & pitfalls

We’ve got another surprise installed for you today… the first episode in the neuro-otology and vertigo series! (Again as an overlap with our ongoing clinical method series). This episode focuses on the HiNTs+ examination in distinguishing central from peripheral causes of an acute vestibular syndrome, in particular distinguishing a posterior circulation stroke (of the brainstem or the cerebellum and its connections) from vestibular neuritis. The episode then changes tack to discuss the Dix-Hallpike examination and then the horizontal head roll (log roll) tests to diagnose posterior canal and geotropic/ageotropic horizontal canal BPPV (benign paroxysmal positional vertigo), respectively, and it also discusses the Epley manoeuvre and barbeque roll (BBQ roll; Lampert roll) manoeuvre in the treatment of posterior canal and horizontal canal BPPV, respectively. As always, the episode is packed to the brim with helpful tips and tricks to help you perform these examinations and techniques optimally and efficiently, along with suggestions to help remember them! This episode is appropriate for medical students, junior doctors, physician and neurology trainees, neurologists, cardiologists/ general practitioners (family doctors)/emergency and intensive care physicians and their respective trainees, and any other health professional assessing patients presenting with dizziness (who may ultimately have a neurologic, cardiac or another cause for this presenting symptom).
