Impaired verbal functioning is linked to altered white matter microstructure in preterm-born adults
Preterm (PT) birth is associated with impaired verbal fluency [1] and verbal processing speed [2]. Interestingly, white matter microstructural alterations in the arcuate fasciculus (AF), superior longitudinal fasciculus (SLF), uncinate fasciculus (UF), and inferior frontooccipital fasciculus (IFOF) -tracts, which are suggested to subserve language ability [3] - have been found in PT-born children [4]. We hypothesized that microstructural alterations of these tracts link with verbal fluency and verbal processing speed impairments in PT-born adults.Sixty-three PT- and eighty-one term-born (FT) a
