Still, strength of hippocampal‐medial parietal lobe connectivity has previously been shown to relate to tau pathology burden in the medial parietal lobe cross‐sectionally (Ziontz et al. 2021; Jacobs et al. 2018), and disruption of hippocampal network connectivity has been proposed as the basis of cognitive deficits in AD (La Joie et al. 2014). Here, MAPT is linked to Cognitive impairment.
