canine idiopathic vestibular syndrome
seen in aged dogs, characterized by the sudden onset of head tilt, nystagmus, rolling, falling and circling, often with considerable distress. The cause is unknown, but a peripheral vestibular lesion is suspected. Signs usually regress within a few days. Called also geriatric vestibular syndrome, 'stroke'.
feline vestibular syndrome

vestibular gland
vestibular membrane
one of the membranes subdividing the osseous labyrinth into three compartments.
vestibular organ
consists of a bony labyrinth containing a membranous labyrinth in the inner ear. Part of the membranous labyrinth is the nonacoustic labyrinth or vestibular organ. The vestibular organ consists of the membranous saccule and utricle and semicircular canals. The semicircular canals contain balance end organs called cristae and the saccule and utricle contain similar end organs called maculae. The organ is essential in the maintenance of the animal's balance.
paradoxical vestibular syndrome
vestibular signs of head tilt and ataxia to the side opposite the lesion. Reported in dogs with tumors of the choroid plexus.

The brain scans revealed differences between the groups in two parts of the brain: an area in the cerebellum where sensory input from the vestibular organs is processed and in the cerebral cortex, which is responsible for the perception of dizziness.
The symptoms will always worsen when the patient needs to rely on the vestibular organs such as closing the eyes, dark environment or walking on uneven ground.
Note that the navigation task stimuli were entirely visual and the subject remained seated throughout; thus, there was no stimulation of the vestibular organs.
