Although prior studies in aging and neurodegenerative diseases indicate actigraphy-estimated rest-activity circadian rhythm disturbances are risk factors for cognitive impairment, it is unclear if this applies to ARF survivors. This study explored the relationships of actigraphy-estimated rest-activity circadian rhythms with cognitive functioning in ARF survivors at 3\u00a0months after discharge.\n                    <jats:bold>Methods<\/jats:bold>\n                    : 13 ARF survivors (mean age 51\u00a0years and 69% males) completed actigraphy and sleep diaries for 9\u00a0days, followed by at-home neuropsychological assessment. Principal component factor analysis created global cognition and circadian rhythm variables, and these first components were used to examine the global relationships between circadian rhythm and cognitive measure scores.\n                    <jats:bold>Results<\/jats:bold>\n                    : Global circadian function was associated with global cognition function in ARF survivors (\n                    <jats:italic toggle=\"yes\">r<\/jats:italic>\n                    = .70,\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    = .024) after adjusting for age, education, and premorbid cognition.
