Larissa Fischer @fislarissa.bsky.social · 26/08/2026Our findings suggest that non-pathological aging and early Alzheimer's pathology relate to distinct MTL network signatures, with higher hippocampal connectivity potentially supporting memory function in the short term while contributing to subsequent memory decline. 000
Larissa Fischer @fislarissa.bsky.social · 26/08/2026We investigated 7T submillimeter fMRI, plasma biomarkers, PI-2620 tau PET, and longitudinal memory data in 75 cognitively unimpaired older adults. 110

Larissa Fischer @fislarissa.bsky.social · 17/12/20245/5 🧳 Our findings highlight region-specific differences in longitudinal rsFC strength between “normal” aging and early AD pathology and shed light on early changes in rsFC strength with AD pathology, which might already be disadvantageous for episodic memory performance in APOE4 carriers. 000
Larissa Fischer @fislarissa.bsky.social · 17/12/20244/5💡 Longitudinal increase in rsFC strength between the anterior hippocampus and the superior precuneus is associated with higher early AD pathology. Higher rsFC strength was related to cognitive decline only in APOE4 carriers. 100
Larissa Fischer @fislarissa.bsky.social · 17/12/20243/5 💡 Longitudinal decrease in rsFC strength within the posteromedial cortex and between the posterior hippocampus and the inferomedial precuneus was associated with “normal” aging. Pathology-independent lower rsFC strength was related to cognitive decline. 100
Larissa Fischer @fislarissa.bsky.social · 17/12/20242/5 💡 In essence, hypoconnectivity was related to aging, hyperconnectivity was related to early Alzheimer’s pathology. But which specific regions were involved?! 100
Larissa Fischer @fislarissa.bsky.social · 17/12/20241/5 🔎 We investigated resting-state functional connectivity (rsFC) in episodic network regions over two years in cognitively normal amyloid- and tau-negative older adults (“normal” aging sample) and in older adults with CSF measurements (AD-biomarker sample). 100
