  • Proprioceptive deficits in all four limbs or fore- and hind-limb on same side of body as lesion

  • Cranial nerve deficits:
    • Jaw weakness, decreased facial sensation (CN V)
    • Decreased palpebral reflex (CN V, VII)
    • Facial paralysis (CN VII)
    • Head tilt, circling, nystagmus (CN VIII)
    • Pharyngeal/laryngeal paralysis (CN IX, X)
    • Tongue paralysis (CN XII)
  • Abnormal respiration
  • Decreased level of consciousness but not dementia (depression, stupor, coma)
