Background: Subjective cognitive decline (SCD) is defined as a self-perceived decline in cognition without objective cognitive impairment and is considered a potential predictor of Alzheimer's disease (AD). However, summary-level neuropsychological test scores often fail to detect subtle cognitive changes in this group, making assessments challenging. ...

Background: Sensory and psychosocial factors are potentially modifiable risk factors for dementia. Social factors and indicators of mental health are associated with cognitive performance and risk for Alzheimer's disease (AD). Sensory impairment can lead to communication and mobility difficulties, reducing social engagement and possibly accelerating c ...

Background: During the COVID-19 pandemic, older adults were considered vulnerable to declines in well-being, especially those with preexisting cognitive impairments. However, qualitative studies have focused on the resilience of cognitively-unimpaired older adults during the pandemic. Therefore, the present study employed both quantitative and qualitative ...

Background: Olfactory identification is impaired early in the clinical continuum of Alzheimer's disease (AD) and is already observable in mild cognitive impairment (MCI). A recent meta-analysis showed significant associations between olfactory identification and episodic memory scores in older adults without cognitive impairment. Thus, olfactory ident ...

Background: Age-related hearing loss (HL) is associated with poorer cognition and increased risk of developing dementia. However, few studies have explored if sex affects the association between HL and cognition. We investigated the relationship between two hearing measures and performance on cognitive screening and neuropsychological tests in males and f ...

BackgroundOlfactory identification decline is a known early marker of Alzheimer's disease and is already present at the mild cognitive impairment (MCI) stage. While being linked with episodic memory, its predictive value for cognitive performance and distinguishing between clinical stages remains unclear.ObjectiveThis study examined (1) the predictive ...

Psychosocial function is associated with cognitive performance cross-sectionally and cognitive decline over time. Using data from the COMPASS-ND study, we examined associations between psychosocial and cognitive function in 126 individuals with mild cognitive impairment, an at-risk group for Alzheimer's disease (AD). Psychosocial function was measured ...

Background: The COVID-19 pandemic caused a drastic shift in the practice of research and clinical services. It has been noted that cognition measured via in-person versus remote methods differ substantially, and it is possible that subjective and experiential differences exist between modalities. Objective: The aim of the study is to explore the percepti ...
