What is Cerebellar Hypoplasia?

Cerebellar hypoplasia is a neurological condition characterized by the underdevelopment or smaller-than-normal size of the cerebellum, a region of the brain responsible for coordinating movement and balance. It is often associated with various congenital malformation syndromes, including Walker-Warburg syndrome. Additionally, it is linked with several inherited metabolic disorders like Williams syndrome, as well as certain early childhood-onset neurodegenerative disorders such as ataxia telangiectasia.


In a newborn or young child, the symptoms cerebellar hypoplasia are floppy muscle tone, developmental delay, speech issues, problems with walking (balancing), seizures, mental retardation and involuntary movements of the eyes. Among other symptoms of the condition are headache, dizzy spells, clumsiness and hearing impairment.


Currently, there is no established standard treatment protocol for cerebellar hypoplasia. Treatment for this neurological condition varies depending on the underlying disorder and the severity of symptoms. It typically involves symptomatic and supportive measures. While some disorders associated with cerebellar hypoplasia are progressive, others are not.
