Vestibular Neuronopathy

Dogs with a vestibular disorder suffer from intense dizziness and other symptoms of virtigo.

Vestibular neuronopathy is a condition, commonly known as vertigo, which is more prevalent in older cats and dogs. The onset is sudden, typically occurs without warning, and closely resembles a stroke or seizure. Animals experiencing symptoms should be evaluated by a veterinarian.

Symptoms

This condition is sometimes referred to as "dizzy kitty" in cats.

Classic indications of this condition include a head tilt, lack of coordination or balance, and nystagmas, including rapid, uncontrollable eye movements. Vomiting, incontinence, and decreased appetite are also common.

Causes

In many cases the condition is sudden, as pets appear otherwise normal. Most cases are diagnosed as "idiopathic," meaning there is no known cause. Other causes include inner-ear infection, various infectious diseases, or brain tumors.

Prognosis

The outcome depends upon the cause, but most idiopathic diagnoses show improvement within the first several days. For this diagnosis most pets take 1 to 3 weeks to fully recover, and relapses can occur.

Treatment

If a cause is determined, treatment of that cause should correct this side-effect. An idiopathic diagnosis simply takes time and patience for the pet recover. Hand-feeding and watering, corticosteroids, and nurturing are all necessary during recovery.
