Spinocerebellar ataxia 7 (SCA7) is an inherited disease of the central nervous system that leads to impairment of specific nerve fibers carrying messages to and from the brain, resulting in degeneration of the cerebellum (the coordination center of the brain).What is an ataxia?
Hereditary Ataxias are genetic, which means they are caused by a defect in a certain gene that is present from the start of a person’s life, inherited from your parents.What is the prognosis of ataxia?
Age of symptom-onset can vary widely, from childhood to late-adulthood. Complications from the disease are serious and oftentimes debilitating. Some types of Ataxia can lead to an early death. Ataxia symptoms vary by person and type of Ataxia. Rate of progression varies as well.What are the different types of cerebellar ataxia?
Cerebellar ataxia and cerebellar degeneration are common to all types, but other signs and symptoms, as well as age of onset, differ depending on the specific gene mutation. Episodic ataxia (EA). There are eight recognized types of ataxia that are episodic rather than progressive — EA 1 through EA 7, plus late-onset episodic ataxia.
