Clinics specialized in ataxia provide specialized medical care for patients with cerebellar ataxia, offering diagnosis, treatment and management of ataxias and prevention and management of complications from the disease. Among the specialists available to ataxia patients are genetic counselors, speech therapists and physical therapists. Ataxias are classified as dominantly inherited, recessive or sporadic. The recessive forms of ataxia have an early onset, most of which occur in childhood. The most frequent in the recessive group is Friedreich’s ataxia in mitochondrial disorders and episodic ataxias. Dominantly inherited and sporadic ataxias generally affect the adult population. The dominantly inherited group includes spinocerebellar ataxias, dentatorubral-pallidoluysian atrophy, and autosomal dominant cerebellar ataxia with progressive pigmentary macular dystrophy. The sporadic group with ataxia as the predominant manifestation includes multiple system atrophy, idiopathic late-onset cerebellar ataxia, corticobasal degeneration, immune diseases, malformation of the cerebellum and posterior fossa, infectious diseases, endocrine disorders, cerebellotoxic agents and cerebral disorders in cancer.
