Found insideThis book is dedicated to David Robinson - one of the pioneers of contemporary ocular motor and vestibular neuroscience. Eight (44%) patients revealed a vertical component (upward) and 15 (83%) patients had a torsional component in the healthy-ear-down position. When the pathophysiological mechanism of the apogeotropic form is that of canalolithiasis, we can observe a transformation from an apogeotropic nystagmus into a geotropic one. Geotropic horizontal positional nystagmus with latency was observed, more prolongued on the left side, where we recorded 10 minute duration and showed more symptomatology and was more intense on the right side, where we recorded 7 minute duration (Video 1 & 2). VIDEO- Right ear HC-with the patient laying on her left side produces an “ageotropic ” nystagmus. In the right head-hanging posi-tion, the patient develops after a short delay an upbeating torsional nystagmus where the torsional component rotates toward the right ear. First let's talk about the prevalence of Horizontal Canal BPPV. 2021 Jul;17(3):443-454. doi: 10.3988/jcn.2021.17.3.443. Subjects were 18 patients with persistent direction-changing geotropic positional nystagmus, 16 females and 2 males, with a mean age of 55 years. Results: Eighteen patients (4 with posterior canal type, 2 with horizontal canal type with geotropic nystagmus, and 12 with apogeotropic nystagmus) fulfilled the above criteria for intractability among 495 BPPV . These results suggest that vertical and torsional components occur from the horizontal semicircular canal, and that horizontal canal ocular reflex is influenced by input from the otolithic organs. Salient features: wide treatment of all features of benign paroxysmal positional vertigo (BPPV) by internationally renowned specialists; analysis of pathogenesis and epidemiological data of BPPV; clinical and diagnostic approach to BPPV ... Benign Paroxysmal Positional Vertigo (BPPV) is the most common cause of vertigo, which is a symptom of the condition.Though not fully understood, BPPV is thought to arise due to the displacement of otoconia (small crystals of calcium carbonate) from the maculae of the inner ear into the fluid-filled semicircular canals.
