Vestibular Disease
Vestibular disease affects the neurological system responsible for balance and spatial orientation. It is commonly (and usually incorrectly) referred to as a "stroke" in pets.
Key Facts
- Vestibular apparatus: middle ear structures + nerves to brain + brain itself
- Signs: stumbling/staggering (ataxia), head tilt, nystagmus (rapid eye movements), motion sickness
- Idiopathic vestibular disease is the most common form in both dogs and cats
- "Old dog vestibular disease": begins acutely, usually improves within 72 hours, resolves in 7-14 days
- Peripheral causes (inner ear): middle ear infection, idiopathic disease
- Central causes (brain): tumors, vascular accidents, infections (Rocky Mountain spotted fever)
- Vertical nystagmus suggests brain (central) lesion
- True vascular stroke is rare in pets unlike in humans
- CT or MRI may be needed to image the brain for central causes
- A residual head tilt may persist even after resolution
- Species: dogs and cats
