What does Cerebellar Hypoplasia Mean?

The word ‘Cerebellar’ refers to the complex part of the brain that controls the range, rate and force of movements [1].
The Cerebellar detects subtle shifts in balance and sends messages to other parts of the dog’s body, so to maintain balance and keep upright.
Coordinates muscles to work together so that the body moves intentionally and smoothly.
The Cerebellar coordinates eye movement.
Helps the body learn fine and gross motor skills. [2]

The word ‘Hypoplasia’ refers to the under-development of an organ or tissue.

The cerebellum is situated at the back of the brain and is responsible for sending fine-tuned motor signals from the brain to the muscles, allowing for balance and coordination [3]. For puppies with CH, like Holly the Labrador, this means that a physical part of the brain is underdeveloped and therefore certain symptoms will be observed early in the puppy’s life.

Holly the Lab UK was diagnosed with CH when she was eight weeks old after a full examination by a vet.  An MRI can be performed to confirm a case of Cerebellar Hypoplasia, however, in Holly’s situation this was not deemed necessary. Although, we can’t be certain of the reasons why Holly is affected by CH it is likely to be a genetic issue.  Other causes of CH can be a blood clot or an infection whilst in the uterus (the latter is mainly found in cats and extremely rare in dogs).
