30 The Acute Vestibular Syndrome in MS Due to Middle Cerebellar Peduncle/Root Entry Zone LesionThis is a 13 year-old girl with relatively abrupt onset vertigo and oscillopsia. On exam, there was primarily right-beating nystagmus in primary gaze with a slight upward (upbeat) component, giving the nystagmus an oblique appearance. The upward component and lack of a clear torsional component acut...Jerk Nystagmus; Vestibular Nystagmus; Vestibulo-ocular Reflex; Head Impulse Testing; Gaze-evoked Nystagmus
31 The Apogeotropic Variant of Horizontal Canal BPPV𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: This is a patient with the apogeotropic (nystagmus beating towards the sky) variant of right horizontal canal (HC) benign paroxysmal positional vertigo (BPPV). In a patient with geotropic (nystagmus beating towards the gr...BPPV Horizontal; BPPV Diagnosis; Jerk Nystagmus; Vestibular Nystagmus
32 The Geotropic Variant of Horizontal Canal BPPV𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: This is a patient with the geotropic (nystagmus beating towards the ground) variant of left horizontal canal (HC) benign paroxysmal positional vertigo (BPPV). In a patient with geotropic (nystagmus beating towards the gro...BPPV Horizontal; BPPV Diagnosis; Jerk Nystagmus; Vestibular Nystagmus
33 Unidirectional Nystagmus in Lateral Medullary SyndromeThis is a 70-yo-man who presented with acute vertigo. Examination demonstrated very mild spontaneous torsional nystagmus (towards the right ear) in primary (not seen well in this video), with robust downbeat-torsional (towards right ear) nystagmus in right gaze and (less robust) almost pure torsiona...Medula; Rotary Nystagmus; Jerk Nystagmus; Acute Vestibula; Vestibular Nystagmus; Abnormal Saccades
34 Upbeat and Downbeat Nystagmus Due to Anti-VGCC AntibodiesSeen here are two patients who presented with imbalance and vertical oscillopsia, the first with upbeat nystagmus, and the second with downbeat nystagmus. Both patients were found to have voltage-gated calcium channel antibodies in serum without evidence of systemic malignancy. The UBN patient had m...Jerk Nystagmus; Upbeat Nystagmus; Gaze Evoked Nystagmus; Downbeat Nystagmus
35 Vestibular Neuritis with + Head Impulse Test and Unidirectional NystagmusVestibular neuritis is the most common cause of the acute vestibular syndrome, which is characterized by continuous vertigo and spontaneous nystagmus lasting days. It may be mimicked by central causes, including stroke, but in the hands of subspecialists, the HINTS+ (Head Impulse, Nystagmus, Test o...Jerk Nystagmus; Acute Vestibular; Vestibular Nystagmus
36 Vestibular Neuritis with + Head Impulse Test and Unidirectional Nystagmus (Figure 1)Vestibular neuritis is the most common cause of the acute vestibular syndrome, which is characterized by continuous vertigo and spontaneous nystagmus lasting days.
