“…In human patients with acute vestibular syndrome, the underlying causes are typically divided into isolated or recurrent conditions. Relapse of vestibular neuritis is rare (1.9%) but benign paroxysmal positional vertigo, Ménière's disease and vestibular migraine will often recur with an approximate prevalence of 30-50%, 45-79% and up to 81% respectively [31][32][33]. It seems likely that dogs diagnosed with IVS may in fact have more than one underlying cause for these signs, therefore explaining the different presentations (mostly related to acute or chronic onset, progression or not of clinical signs and concurrent facial nerve deficits or not), MRI findings (enhancement or not of cranial nerves VII and/or VIII), outcome and recurrence of clinical signs.…”

Background: Vestibular dysfunction is relatively common in dogs, with a prevalence of 0.08% reported in primary veterinary care in the UK. There are several studies investigating how to differentiate between peripheral and central vestibular disease but only limited information regarding the possible underlying causes for peripheral vestibular dysfunction in dogs. This study therefore aimed to describe the clinical signs, magnetic resonance imaging findings (MRI), underlying causes and outcome in a large population of dogs diagnosed with peripheral vestibular disease. Results: One hundred eighty-eight patients were included in the study with a median age of 6.9 years (range 3 months to 14.6 years). Neurological abnormalities included head tilt (n = 185), ataxia (n = 123), facial paralysis (n = 103), nystagmus (n = 97), positional strabismus (n = 93) and Horner syndrome (n = 7). The most prevalent diagnosis was idiopathic vestibular disease (n = 128), followed by otitis media and/or interna (n = 49), hypothyroidism (n = 7), suspected congenital vestibular disease (n = 2), neoplasia (n = 1) and cholesteatoma (n = 1). Long-term follow-up revealed persistence of head tilt (n = 50), facial paresis (n = 41) and ataxia (n = 6) in some cases. Recurrence of clinical signs was observed in 26 dogs. Increasing age was associated with a mild increased chance of diagnosis of idiopathic vestibular syndrome rather than otitis media and/or interna (P = 0.022, OR = 0.866; CI 0.765-0.980). History of previous vestibular episodes (P = 0.017, OR = 3.533; CI 1.251-9.981) was associated with an increased likelihood of resolution of the clinical signs whilst contrast enhancement of cranial nerves VII and/or VIII on MRI (P = 0.018, OR = 0.432; CI 0.251-0.868) was associated with a decreased chance of resolution of the clinical signs. Conclusions: Idiopathic vestibular disease is the most common cause of peripheral vestibular dysfunction in dogs and it is associated with advanced age. Incomplete recovery from peripheral vestibular disease is common, especially in dogs presenting with cranial nerve enhancement on MRI but less so if there is previous history of vestibular episodes.

“…10 Pollak and Michael have reported that the incidence of bilateral posterior canal BPPV is 6.9 per cent of all cases of posterior canal BPPV. 11 However, Imai et al have reported that bilateral posterior canal BPPV accounted for 1.4 per cent of cases, 4 and Hotta et al reported a 2.2 per cent incidence. 3 The incidence of true and pseudo bilateral posterior canal BPPV in this study was 3.1 per cent and 12.6 per cent, respectively.…”

Objective To outline the clinical picture of bilateral posterior canal benign paroxysmal positional vertigo. Methods A total of 573 patients with posterior canal benign paroxysmal positional vertigo were classified as having unilateral, or true or pseudo bilateral, posterior canal benign paroxysmal positional vertigo, and were treated with the Epley manoeuvre. Statistical significance was set at p < 0.05. Results Of the patients, 483 had unilateral and 90 (15.7 per cent) had bilateral presentation. Of the latter, 72 patients had pseudo bilateral posterior canal benign paroxysmal positional vertigo. Comparisons of site of involvement, male to female ratio and the incidence of associated problems in unilateral, and true and pseudo bilateral posterior canal benign paroxysmal positional vertigo did not reveal any statistically significant differences (p = 0.828, p = 0.200, p = 0.142). Comparisons of the number of manoeuvres required to provide symptom relief and the rate of recurrence were significant (p < 0.05). Conclusion Identification of true and pseudo bilateral posterior canal benign paroxysmal positional vertigo is important given the differences in aetiology and treatment outcome. Treatment of patients with true bilateral posterior canal benign paroxysmal positional vertigo requires several therapeutic manoeuvre attempts, and patients should be warned about recurrence.

“…Recurrence of clinical signs in dogs with IVS is reported in approximately one‐quarter of cases (Orlandi et al, 2020). In human patients, relapse is also commonly seen with vestibular neuritis, benign paroxysmal positional vertigo, Ménière's disease and vestibular migraine (Fushiki et al, 2009; Maione, 2006; Pollak & Michael, 2019). No recurrence was observed in any of the cases in this study.…”

Suspected idiopathic vestibular syndrome in the horse: Eight cases (2014–2021)

SummaryA descriptive case series of the presentation, diagnosis, treatment and outcome of eight horses presenting to a UK equine veterinary hospital with suspected idiopathic peripheral vestibular syndrome over a 7‐year period (2014–2021). Idiopathic vestibular syndrome in the horse causes unilateral clinical signs including; ataxia, nystagmus, strabismus and a head tilt. Diagnosis is aided by neurological examination, endoscopy of the upper airway and cross‐sectional imaging (i.e. magnetic resonance imaging and computed tomography). This case series indicates that horses with this condition can make a full recovery with return to ridden exercise. Treatment with anti‐inflammatory medication did not appear to influence outcome.
