| IDIOPATHIC VESTIBULAR DISEASE/SYNDROME | |
| Description | Idiopathic Vestibular Disease/Syndrome is a common cause of canine peripheral vestibular signs. This peracute condition is most frequent in older dogs. The three clinical hallmarks: head tilt; ataxia; and nystagmus can be initially severe. Often misdiagnosed as a 'stroke'. Normal strength and postural reactions might be masked by ataxia and spatial disorientation. Recovery is spontaneous but can take a few days to a few weeks and residual dysfunction might remain. Feline Acute Idiopathic Vestibular Disease affects adult cats. Affected cats are reluctant to move and might crouch against a wall. Signs are bilateral at first but one side will usually predominate. There is improvement over a period of 2-4 weeks, but residual signs might persist. Idiopathic Facial Neuropathy occasionally accompanies this disease. Rare in other species. |
