The presence of spasticity and pyramidal features is a hallmark of some of hereditary ataxias, such as autosomal-recessive spastic ataxia of Charlevoix-Saguenay, other primary spastic ataxias, Friedreich ataxia, or ataxia with isolated vitamin E deficiency.
This study showed that in Algerian patients, the two most common types of ataxia (Friedreich ataxia and ataxia with isolated vitamin E deficiency) coexist with forms that may be less common or underdiagnosed.
Ataxia with vitamin E deficiency (AVED), or familial isolated vitamin E deficiency, is a rare autosomal recessive neurodegenerative disease characterized clinically by symptoms with often striking resemblance to those of Friedreich ataxia.
