One of the most promising interventional targets for brain health is cerebral perfusion, but its link to white matter (WM) aging remains unclear. Motivated by existing literature demonstrating links between declining cortical perfusion and the development of WM hyperintensities, we posit that regional WM hypoperfusion precedes deteriorating WM integrity. ...

Super-resolution imaging has emerged as a rapidly advancing field in diagnostic ultrasound. Ultrasound Localization Microscopy (ULM) achieves sub-wavelength precision in microvasculature imaging by tracking gas microbubbles (MBs) flowing through blood vessels. However, MB localization faces challenges due to dynamic point spread functions (PSFs) caused by ...

Study objectives: Insomnia in older adults is associated with widespread benzodiazepine (BZD) and benzodiazepine receptor agonist (BZRA) use, despite evidence that chronic use disrupts sleep regulation and cognition. Little is known about BZD/BZRA effects on NREM slow oscillations (SO), spindles ...

Aging in place is an important environmental consideration in gerontology from the standpoint of research and aging individuals. While the majority of aging adults in the U.S. prefer aging in place to relocating to different environments (e.g., retirement communities, cohabitation with adult children), many barriers prevent this outcome. For example, for ...
