Purpose: Reduced volumes in brain areas of temporal lobe epilepsy (TLE) patients is commonly observed. Alterations in white matter connectivity have also been shown. However, it is not fully understood how these are related.
Method: In this study we compare regional and network features of patient and control connectome maps. We compare data from 22 patients with left TLE and 39 control subjects.
Results: We find that patients have significant alterations in region size but only subtle changes in white matter connectivity. When region size and white matter connectivity are combined this leads to significant alterations in connectivity strength.
Conclusion: Connectomics is frequently used to compare brain networks, however our results suggest caution should be used when interpreting the results where there are known alterations in regional properties. Our work unifies results from regional and connectomic literature.
