But pathology in AD isusually largely symmetrical between the hemispheres, and therefore leaves lessroom for biases in the observed correlations, as claimed in a recent study(Ravikumar et al., 2021) which showedthat correlations between MTL thickness maps and both contralateral andipsilateral semi-quantitative p-tau pathology scores did not detectsubstantially different correlation patterns. Here, MAPT is linked to Alzheimer disease.
