Machado DS, Silveira C, Vinagre AM, Rezende TJR, Dogini D, Martinez ARM, França MJC. Survival in Brazilian Patients with Friedreich´s Ataxia. Cerebellum. 2025 Nov 22;24(6):182. doi: 10.1007/s12311-025-01936-6. PMID: 41273607.

Shorter life expectancy was found: in men relative to women (Mean age: 54.0 yo vs. 56.8 yo, p = 0.03), in patients with classical relative to late-onset (Mean age: 52.2 yo vs. 71.0 yo, p < 0.01) and in patients with cardiomyopathy relative to those without it (Mean age: 50.8 yo vs. 65.0 yo, p < 0.01). FRDA impacts life expectancy and death is primarily from cardiac and pulmonary causes. Male sex, early onset and presence of cardiomyopathy are negative survival prognostic markers.
