MRI-assessed locus coeruleus integrity is heritable and associated with multiple cognitive domains, mild cognitive impairment, and daytime dysfunction

TL;DR: Elman et al. as discussed by the authors indexed the locus coeruleus (LC) structural integrity by neuromelanin-sensitive magnetic resonance imaging (MRI) contrast-to-noise ratio (LCCNR) and found that lower LCCNR was associated with poorer episodic memory, general verbal fluency, semantic fluency and processing speed, as well as increased odds of mild cognitive impairment and greater daytime dysfunction.
White matter disease in midlife is heritable, related to hypertension, and shares some genetic influence with systolic blood pressure.

TL;DR: Abnormal white matter was highly heritable and shared some genetic influences with systolic blood pressure, although there was evidence for distinct genetic contributions and unique environmental influences.
Posttraumatic stress symptom persistence across 24 years: association with brain structures
Carol E. Franz,Sean N. Hatton,Richard L. Hauger,Richard L. Hauger,M. Alexandra Kredlow,Anders M. Dale,Lisa T. Eyler,Linda K. McEvoy,Christine Fennema-Notestine,Donald J. Hagler,Kristen C. Jacobson,Ruth E. McKenzie,Matthew S. Panizzon,Daniel E. Gustavson,Hong Xian,Rosemary Toomey,Asad Beck,Samantha M. Stevens,Xin M. Tu,Michael J. Lyons,William S. Kremen,William S. Kremen +21 more
TL;DR: It is predicted that persistent PTS symptoms across ~24 years would be inversely associated with hippocampal, amygdala, anterior cingulate volumes, and hippocampal occupancy in late middle age, and this work confirmed this prediction.

TL;DR: In this article, a grey matter mean diffusivity signature was used to predict progression from mild cognitive impairment to Alzheimer's disease in cognitively normal middle-aged adults, and the results held up after adjusting for predicted brain age difference scores.
Paradoxical cognitive trajectories in men from earlier to later adulthood.

TL;DR: For example, this article found that individuals with higher age 20 GCA outperformed those whose GCA remained stable in terms of memory, executive function, and working memory abilities from age 51 to 73.
