Vertigo

Reference: North Central London Dizziness Pathway 2019

Data gathering

  • Red flags
    • acute onset hearing loss + vertigo -> contact ENT on call
    • CN symptoms, limb weakness, cerebellar signs, severe headache -> urgent HASU review
  •  History
    • Menieres – ear fullness, tinnitus
    • BPPV – head movement triggers vertigo
    • Vestibular neuronitis – prodromal viral URTI, continuous spinning, vomiting
    • Vestibular migraine – recurrent episodes of vertigo, nausea, photophobia, phonophobia, often normal examination
    •  
  • Dysequilibrium (unsteadiness)
    • multisensory imbalance – elderly patient, vision, proprioception

  • Examine
    • ENT exam
    • CN exam
    • Cerebellar exam
    • L/S BP
    • Dix-Hallpike
    • Head impulse test (negative in central causes)

 

Clinical management

  • Investigations
      • Bloods – FBC, U+Es, TFTs, HbA1c
      • Bedside BM
      • Audiometry
  • Treatment
    • BPPV
      • Epley manoeuvre, Brandt-Daroff exercises, refer if not settled after 4 weeks
    • Vestibular neuronitis
      • Prochlorperazine (max 3 days), refer if not settled after 4 weeks
    • Vestibular migraine
      • Only treat if known vestibular migraine – prochlorperazine 5mg TDS, refer if symptoms persist more than 6 weeks
    • Multisensory imbalance
      • Refer to falls clinic

 

Notes

  • Cerebellar examination
    • DANISH
      • Dysdiadochokinesia
      • Ataxia (gait and posture)
      • Nystagmus
      • Intention tremor
      • Slurred, staccato speech
      • Hypotonia/Heel-shin test
  • Dix-Hallpike test for BPPV
    • Patient in a sitting position
    • Rapidly lay the patient down flat on a couch with head turned to the side and neck extended (ensure no neck pathology)
    • A nystagmus occurs if BPPV present

 

  • Long term use of prochlorperazine, cinnarizine
    • generally recommended to avoid as slows central compensation and creates psychological dependence – advise patients to mobilise as much as possible to compensate quicker
