Cerebellar Ataxia - Neuropathy - Vestibular Areflexia Syndrome

CANVAS Syndrome


Presentation

  • Cerebellar ataxia, neuropathy, and vestibular areflexia syndrome: a slowly progressive disorder with stereotypical presentation . Journal of Neurology , 263 (2), 245-249.[moh-it.pure.elsevier.com]
  • Thirteen patients presented with gait imbalance, 8 of whom noted this to be worse in the dark. Two patients reported dizziness on presentation, while only one patient gave an account of intrinsic falls.[docplayer.net]
  • An impaired or saccadic vVOR suggests that there is failure of both the pursuit and (bilateral) vestibular systems, and CANVAS should be considered, especially when neuropathy is present.[collections.lib.utah.edu]

Oscillopsia
  • Van Stavern, MD, Associate Professor, Ophthalmology & Visual Sciences and Neurology, Washington University School of Medicine Description A 67 year old woman presented with 1 year of progressive numbness, gait instability, and oscillopsia when walking[collections.lib.utah.edu]
  • Clinical presentation DusanPavlovic.com  60yr mean age, equal sex distribution  11yr after onset  instability  dyasthesia  oscillopsia  dizziness  intrinsic falls March 30th 2015 5.[slideshare.net]
  • Actually this is the prevalence of oscillopsia alone, which is a piece of BVL, but might have other causes, so it may overestimate the prevalence. There must be less CANVAS patients than BVL. We have 329 BVL patients in our practice database.[dizziness-and-balance.com]
  • A minority of patients also have movement-induced oscillopsia, in particular while walking. The diagnosis of BVP is based on a bilaterally reduced or absent function of the vestibulo-ocular reflex (VOR).[readbyqxmd.com]
Positive Romberg Sign
  • All patients showed gait and limb ataxia, positive Romberg sign, cerebellar dysarthria, gaze-evoked nystagmus, absent deep tendon reflexes, and impaired vibratory sensation.[moh-it.pure.elsevier.com]
  • It should be noted that the finding of a positive Romberg sign may reflect functional impairment of either or both vestibular and proprioceptive function, a point which is particularly relevant to a condition which comprises defects in both of these systems[docplayer.net]

Workup

  • The symptoms described by you could be due to neuropathy. labs for neuropathy workup I suspect it is the methotrexate.[christopherglaze.club]
  • Symptoms can be precipitated by hyperventilation, and workup includes an MRI, as certain heavily T2 weighted sequences can show a blood vessel compressing the 8 th cranial nerve in the CPA (cerebellopontine angle) or the IAC (internal auditory canal).[ohns.ucsf.edu]
  • Purkinje cells) Clinical Features Epidemiology Female: 80% (US study); 15% (European study) White: 98% Age of onset: Mean 60's; Range 39 to 83 Tobacco smoking: 95% Onset Painful paresthesias & dysesthesias Asymmetric; Distal or Proximal No tumor at initial workup[neuromuscular.wustl.edu]

Treatment

  • There are very minimal treatment options for this rare disorder because it is not found in many patients. The treatment is symptomatic and you will need assistive devices because you have 3 impediments to balance.[hearingaidsfortlauderdale.com]

Etiology

  • We measured horizontal and vertical semicircular canal function using the video-head-impulse test (vHIT) and hypothesized that specific vHIT-patterns may be linked to certain etiologies.[readbyqxmd.com]

  • CANVAS (cerebellar ataxia with neuropathy and vestibular areflexia syndrome) is a rare neurological syndrome of unknown etiology. The main clinical features include bilateral vestibulopathy, cerebellar ataxia and sensory neuropathy.[eurekamag.com]
  • Dermatologists need to know when a diabetic peripheral neuropathy powerpoint presentation patient should be referred to a neurologist and should consider this option in those presenting with syndromes of unclear etiology.[marymoyle.club]
  • The exact etiology of neurologic injury related to PNB remains unclear in many instances. Another much quoted series followed 24 patients for six and a half years.[christopherglaze.club]
