The Famous Names Discrimination Task As A Biomarker Of Alzheimer's Disease Risk: An Erp Study, Elizabeth Rose Paitel
The Famous Names Discrimination Task As A Biomarker Of Alzheimer's Disease Risk: An Erp Study, Elizabeth Rose Paitel
Master's Theses (2009 -)
Current ERP research emphasizes age- and pathology-related declines in neural processing in the form of attenuated amplitudes and prolonged latencies. Notably, there is a gap in the ERP literature regarding neural processing trajectories in the time between healthy young adulthood and clinical MCI/AD samples. fMRI research, however, has demonstrated periods of increased, compensatory activation in healthy, cognitively intact APOE ɛ4 carriers both during resting state and event-related tasks (Bondi, Houston, Eyler, & Brown, 2005; Evans et al., 2014; Filippini et al., 2009; Rao et al., 2015), consistent with compensatory theories of cognitive aging (Cabeza, 2002; Park & Reuter-Lorenz, 2009; Reuter-Lorenz …
Mechanisms Of Fatigue With Aging: Evidence From The Whole-Limb To The Single Cell In Humans, Christopher W. Sundberg
Mechanisms Of Fatigue With Aging: Evidence From The Whole-Limb To The Single Cell In Humans, Christopher W. Sundberg
Dissertations (1934 -)
Aging is accompanied by a loss of muscle mass and increased fatigability of limb muscles making it difficult for old adults to generate the force and power necessary to perform daily activities, such as ascending a flight of stairs. The mechanisms for the age-related increase in fatigability in old and very old adults (≥80 yrs) and whether there are differences between men and women are unknown. The purpose of this dissertation was to determine the mechanisms for the age-related increase in fatigability in men and women by studying fatigue at the level of the whole-limb and within the muscle cells. …
The Impact Of Advance Directives On The Intensity Of Care Received In The Acute Care Setting In Older Adults, Marsha Helen Tyacke
The Impact Of Advance Directives On The Intensity Of Care Received In The Acute Care Setting In Older Adults, Marsha Helen Tyacke
Dissertations (1934 -)
The proportion of older adults in the U.S. is rapidly increasing. One-third of Medicare expenditures occur in the final year of life, with nearly half resulting from acute exacerbations of chronic, progressive diseases(Riley & Lubitz, 2010). Older adults prefer comfort over life-sustaining care, and decreased intensity of care is associated with improved quality of life at the end-of-life (EOL). Advance directives (ADs) have been proposed as mechanisms to improve congruence between patient wishes and EOL care; however, the impact of ADs on care delivered in the acute care setting at the EOL for this population is unclear. A retrospective, correlation …
