- What is Cerebellar Hypoplasia?
- The cerebellum is the part of the brain that regulates the control and coordination of movement. In this condition, the cells of the cerebellum do not mature normally before birth, causing clinical signs relating to poor balance and incoordination.
- How is Cerebellar Hypoplasia inherited?
- There is some evidence that the mode of inheritance is autosomal recessive.
- What breeds are affected by Cerebellar Hypoplasia?
- This is an uncommon disorder. It occurs in the chow chow, Irish setter, wirehaired fox terrier, bull terrier, Boston terrier.
- For many breeds and many disorders, the studies to determine the mode of inheritance or the frequency in the breed have not been carried out, or are inconclusive. We have listed breeds for which there is a consensus among those investigating in this field and among veterinary practitioners, that the condition is significant in this breed.
- What does Cerebellar Hypoplasia mean to your dog & you?
- The cerebellum is the part of the brain that regulates the control and coordination of voluntary movement. The clinical signs of cerebellar dysfunction in affected puppies range from mild to severe, and may include poor balance, a wide-based stance (feet planted far apart), stiff or high-stepping gait, apparent lack of awareness of where the feet are (standing or walking with a foot knuckled over), and head or body tremors. Affected pups have normal mental alertness.
- In this condition, in contrast to cerebellar abiotrophy, signs of cerebellar dysfunction are evident at birth or by 2 weeks thereafter, and do not get worse as the pup ages. Other than the abnormalities in balance and coordination, the animal's general health is unaffected.
- How is Cerebellar Hypoplasia diagnosed?
- The clinical signs (relating to uncoordinated movement and lack of balance) are suggestive of a cerebellar disorder. Your veterinarian will do tests to rule out other conditions that can cause similar signs.
- How is Cerebellar Hypoplasia treated?
- There is no treatment for this condition. Affected dogs will not get any worse (or better) and, especially where the signs are mild, may be able to lead a relatively normal life, particularly if owners can adjust their expectations to the dog's limitations.
- Breeding advice
- Affected dogs, their parents and their siblings should not be used for breeding.
