Finally, a number of abnormal behaviours measured by the CBI-R were correlated with the VA, VLp and VLa regions in the thalamus in both sporadic and genetic bvFTD, but with stronger correlations in the C9orf72 expansion carriers, which also involved other regions such as the MD and intralaminar [15,48]. The gene discussed is C9orf72; the disease is behavioral variant of frontotemporal dementia.
