Central Vestibular Disorders
Central vestibular disorders may occur in dogs and are due to an abnormality within the brain. Dogs that have vestibular disorders may have trouble walking or standing.

Identification
-
Vestibular disorders are divided into two categories. Central vestibular disorders occur within the brain, and peripheral vestibular disorders are due to a problem with the nerves of the dog's inner ear. The vestibular system is responsible for informing the brain about the movements of the body. Vestibular disorders affect the brain's ability to recognize normal body movements and positions.
Symptoms
-
The symptoms associated with central vestibular disorders are tilting of the head, rolling of the eyes, circling, lack of coordination and head tremors.

Causes
-
Diseases such as distemper, Lyme disease, Rocky Mountain spotted fever and granulomatous meningoencephalomyelitis (an inflammatory disease of the central nervous system) often cause central vestibular disorders in dogs. Other causes of this condition may be thiamine deficiency, brain tumors and liver disease.
Diagnosis
-
The diagnosis of central vestibular disorders in dogs is made by using diagnostic tools such as an MRI, a blood chemistry profile and a spinal tap. Dogs that suffer from central vestibular disorders may be referred to a neurologist for further evaluation and treatment.
Treatment
-
The treatment for central vestibular disorders depends on the cause. Central vestibular disorders are often more difficult to treat than peripheral vestibular disorders. This condition is more common in dogs older than 12.
