“…hippocampus) and the posterior cingulate cortex, is an important structure for memory function, especially verbal memory performance (Fellgiebel et al, 2005;Sepulcre et al, 2008;Sexton et al, 2010). Many DTI studies in mild cognitive impairment (MCI) and AD patients have shown that early WM damage, is located, among others, in the (posterior) cingulum at an early stage in neurodegeneration and may be a key marker of early pathology (Catheline et al, 2010;Choo et al, 2010;Chua et al, 2009;Fellgiebel et al, 2005;Kiuchi et al, 2009;Nakata et al, 2008;Xie et al, 2005;Zhang et al, 2007). To our best knowledge all studies done so far had relatively small sample sizes (n b 249), used mostly only MCI and AD patients, and did not or only limited adjust for possible confounders.…”
