Friedreich ataxia: Rare Disease

Friedreich ataxia is listed as a "rare disease" by the Office of Rare Diseases (ORD) of the National Institutes of Health (NIH). This means that Friedreich ataxia, or a subtype of Friedreich ataxia, affects less than 200,000 people in the US population.

About prevalence and incidence statistics:

The term 'prevalence' of Friedreich ataxia usually refers to the estimated population of people who are managing Friedreich ataxia at any given time. The term 'incidence' of Friedreich ataxia refers to the annual diagnosis rate, or the number of new cases of Friedreich ataxia diagnosed each year. Hence, these two statistics types can differ: a short-lived disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence. For more information see about prevalence and incidence statistics.
