简介
Objective
The resting‐state functional connectome has not been extensively investigated in amyotrophic lateral sclerosis (ALS) spectrum disease, in particular in relationship with patients' genetic status.
Methods
Here we studied the network‐to‐network connectivity of 19 ALS patients carrying the C9orf72 hexanucleotide repeat expansion (C9orf72+), 19 ALS patients not affected by C9orf72 mutation (C9orf72−), and 19 ALS‐mimic patients (ALSm) well‐matched for demographic and clinical variables.
Results
When compared with ALSm, we observed greater connectivity of the default mode and frontoparietal networks with the visual network for C9orf72+ patients (P = 0.001). Moreover, the whole‐connectome showed greater node degree (P < 0.001), while sensorimotor cortices resulted isolated in C9orf72+.
Interpretation
Our results suggest a crucial involvement of extra‐motor functions in ALS spectrum …
