Genome Wide Analysis Across Alzheimer’s Disease Endophenotypes: Main Effects and Stage Specific Interactions
Tanner Y. Jacobson,Kwangsik Nho,Shannon L. Risacher,Sujuan Gao,Li Shen,Tatiana Foroud,Andrew J. Saykin +6 more
TL;DR: In this paper, the SNPxDX model identified three significant genetic loci (BACH2, EP300, PACRG-AS1) associated with a neuroprotective effect in later AD stage endophenotypes.
Journal ArticleDOI
Mutation ∆K281 in MAPT causes Pick’s disease
Manuel Schweighauser,Holly J. Garringer,Therése Klingstedt,K. Peter R. Nilsson,Masami Masuda-Suzukake,Jill R. Murrell,Shannon L. Risacher,R. Vidal,Sjors H.W. Scheres,Michel Goedert,Bernardino Ghetti,Kathy Newell +11 more
TL;DR: In this paper , the core of tau filaments was made of residues K254-F378 of 3R Tau and was indistinguishable from Pick's disease and they concluded that MAPT mutation ∆K281 causes Pick's Disease.

Edge Time Series Components of Functional Connectivity and Cognitive Function in Alzheimer's Disease
Evgeny J. Chumin,Sarah A. Cutts,Shannon L. Risacher,L. Apostolova,Martin R. Farlow,Brenna C. McDonald,Y-C. Wu,Richard F. Betzel,Shianne J. Andrew,Olaf Sporns +9 more
TL;DR: In this paper , the authors investigated relationships between functional connectivity components, each derived from a subset of time points based on co-fluctuation of regional signals, and measures of domain-specific neuropsychological functions.

TL;DR: In this paper , item-level self-report questionnaire data from international aging studies was linked with item response theory (IRT) techniques using a graded response model with a Bayesian estimator, and items that made the greatest contribution to measurement precision (i.e., "top items") assessed general and specific memory problems.

Neurological correlates of social bonding and bridging
Mohit K. Manchella,Paige E. Logan,Brea L. Perry,Siyun Peng,Lucas J Hamilton,Shannon L. Risacher,Andrew J. Saykin,Liana G. Apostolova +7 more
TL;DR: In this article , the authors analyzed social network and structural MRI data of 176 older adults from the Social Networks and Alzheimer's Disease (SNAD) study and found that increased social bridging is associated with greater grey matter (GM) volume in several limbic structures.
