Background: Cognitive impairment (CI) is a prevalent condition characterized by loss of brain volume and changes in cognition, motor function, and dual-tasking ability. Objective: To examine associations between brain volumes, dual task performance, and gait and balance in those with CI to elucidate the mechanisms underlying loss of function. Methods: We performed a retrospective analysis of medical records of patients with CI and compared brain volumes, dual task performance, and measures of gait and balance. Results: Greater cognitive function and combined dual task effect (DTE) is associated with smaller brain volumes. In contrast, greater motor DTE is associated with larger …

Background: Disrupted sleep is common among nursing home patients with dementia and is associated with increased agitation, depression, and cognitive impairment. Detecting and treating sleep problems in this population are therefore of great importance, albeit challenging. Systematic observation and objective recordings of sleep are time-consuming and resource intensive and self-report is often unreliable. Commonly used proxy-rated scales contain few sleep items, which affects the reliability of the raters' reports. The present study aimed to adapt the proxy-rated Sleep Disorder Inventory (SDI) to a nursing home context and validate it against actigraphy. Methods: Cross-sectional study of 69 nursing home patients, 68% …
