Cerebellar Ataxia (Spinone Italiano type) is an inherited neurological disease affecting dogs. Affected dogs present around 4 months of age with progressive neurological dysfunction due to nerve cell degeneration in a part of the brain known as the Cerebellum. The cerebellum plays an important role in controlling movement. Clinical signs include uncoordinated movement (ataxia), wide-based stance, high-stepping gait, abnormal eye movements, poor balance, loss of menace response (a type of blink reflex), and head tremors which become more severe over time. Though the speed of progression is variable, affected dogs may be unable to stand by one year of age and are often euthanized due to quality-of-life concerns.
