Stroke (Cerebrovascular Accident)
Critical
A stroke occurs when blood flow to part of the brain is interrupted, either by a blood clot (ischaemic stroke) or a bleeding blood vessel (haemorrhagic stroke). While less common in pets than in humans, strokes can still occur and require prompt medical attention.
Signs of Stroke:
- Sudden onset of symptoms without progressive worsening
- Head tilt
- Circling or walking in one direction
- Loss of balance or coordination
- Weakness or paralysis on one side of the body
- Abnormal eye movements or positioning
- Sudden blindness
- Collapse
- Changes in behaviour or mental state
- Seizures
Risk Factors:
- Advanced age
- Heart disease
- Cushing's disease
- Kidney disease
- Hypertension (high blood pressure)
- Hypothyroidism
- Cancer
Emergency First Aid:
- Remain calm and keep your pet calm.
- Ensure your pet is in a safe position (cannot fall or injure themselves).
- Note the time symptoms began.
- Keep the room quiet and dimly lit if possible.
- Do not give any medications unless directed by a veterinarian.
- Transport to an emergency veterinarian as soon as possible.
Important Warning
Stroke symptoms can sometimes be confused with vestibular disease, which often has a better prognosis. Regardless of the cause, immediate veterinary care is essential for proper diagnosis and treatment. Many pets can recover from strokes with appropriate care.
