Cerebellar Hypoplasia

What is Cerebellar Hypoplasia?

Cerebellar hypoplasia is a developmental disorder characterised by the incomplete or underdevelopment of the cerebellum. It may be genetic, or occur sporadically. Cerebellar hypoplasia may be caused by thyroid abnormalities, environmental influences such as drugs and chemicals or viral infections, or stroke. In infancy, symptoms may include developmental delay, hyptonia, ataxia, seizures, mental retardation, and involuntary eye movements (nystagmus). At later ages, symptoms include headache, vertigo, imbalance, and hearing impairment. Cerebellar hypoplasia may be associated with other disorders including Dandy Walker syndrome, Werdnig-Hoffman syndrome, and Walker-Warburg syndrome.

Is there any treatment?

There is no standard course of treatment for cerebellar hypoplasia. Treatment is symptomatic and supportive.

What is the prognosis?

Cerebellar hypoplasia is a progressive disorder.
