Structural connectivity correlated with tau deposition in the anterior and posterior cingulate cortices (Figure 5) and revealed decreased connectivity of the CC, SLF, cingulum, CST, ML, and SCP/MCP (FDR = 0.019) in the CN group, and decreased connectivity of the ILF, IOF, CST, and MCP (FDR = 0.024) in the AD‐spectrum group. Here, MAPT is linked to Alzheimer disease.
