Part A demonstrated semantic deficits in MND and FTD-MND.
Semantic deficits correlated with anterior temporal atrophy on voxel-based morphometry.
Specifically, semantic deficits were assessed and compared to SD, whereas ability to interpret grammar was compared to PNFA.
While semantic deficits appear to be a feature of both MND and FTD-MND, deficits in grammar interpretation were able to distinguish the FTD-MND patient cohort.

However, there were only group differences in the P2 (reflecting attentional demands and stimulus evaluation) and P300 (reflecting stimulus evaluation and memory updating) components, but not in the N400 (reflecting semantic processing) component, suggesting that semantic processing in poor readers may not be a semantic deficit, but the late reflection of an early word decoding problem [45].
Even though previous studies suggested functional brain abnormalities during semantic processing tasks in dyslexia in the visual modality, some studies further suggested that this semantic difficulty may not be a semantic deficit per se, but just a developmental delay due to poor word decoding skills [44], [45].
