The Test of Everyday Attention Reveals Significant Sustained Volitional Attention and Working Memory Deficits in Friedreich Ataxia

Sustained volitional attention and working memory capacity was examined for the first time in people with Friedreich ataxia (FRDA). We administered subtests of the Test of Everyday Attention to 16 individuals with molecularly confirmed FRDA and gender-, age-, and IQ-matched controls. Clinically significant impairment in working memory and sustained volitional attention was evident.
