“…due to dementia, speaking difficulties). The proxy interviews were excluded here because variables including social network, depression, and cognition were not assessed through the proxies (Chan et al, 2011;Malhotra et al, 2015). Another major source of missing data was the record of body mass index (BMI).…”

“…This impression may also affect the interviewer's interpretation of the responses provided. Hence, following Malhotra et al (2015), we analyzed and reported corrected cognitive scores. Cognitive scores were adjusted for interviewer error by subtracting the random intercept estimates for each interviewer, which were obtained in multilevel analysis, from the SPMSQ score for each of their respondent.…”

Being married and having stronger social networks may buffer against the negative cognitive impact of extreme sleep duration. But larger household size might imply more stress for older persons, and therefore strengthen the sleep duration-cognitive function association. We discuss the potential biological underpinnings and the policy implications of the findings. Although our findings are based on a large sample, replication studies using objective measures of sleep duration and other cognitive measures are needed.

“…It has also been used in community samples to identify persons 65 years and older with cognitive impairment and clinically diagnosed Alzheimer's disease ( Albert et al, 1991 ). Moreover, studies have used this scale as a measure of global cognition ( Sachs-Ericsson and Blazer, 2005 , Sawyer et al, 2008 ) and have validated the sensitivity of this instrument for interviewer error when assessing cognitive functioning among older adults ( Malhotra et al, 2015 ). The measure tests a participant’s orientation (i.e., identifying today’s date and day of the week), knowledge of current and past affairs (i.e., naming the current and former Presidents of the United States), and working memory (i.e., using the serial 3s subtraction test).…”

Black-white mental status trajectories: What ages do differences emerge?

ObjectivesStudies of older U.S. adults have consistently found that African Americans perform worse on cognitive measures than whites, but there are inconsistencies as to whether these findings hold over time. Moreover, studies have focused on adults 51 and older, without considering younger ages; thus it is unclear the age at which these disparities surface. The present study examines black-white disparities in mental status trajectories among adults as young as 25 years over a 25-year period.MethodData come from the Americans’ Changing Lives Study (ACL) (n = 3,617). Participants, ranging from ages 25–100 years old at baseline, were followed from 1986 to 2011 over 5 waves. Mental status was assessed at each wave using a 5-item Short Portable Mental Status Questionnaire. Growth models were used to estimate the associations between age, race, baseline status, and longitudinal changes in mental status, controlling for sociodemographic (e.g., education, income) and other health risk factors (diabetes, stroke, tobacco use, depression).ResultsRacial disparities were seen beginning in midlife and this relationship was curvilinear. Specifically, blacks had a steeper rate of mental status decline than whites and these disparities persisted after accounting for social and health risk factors (b = 0.0090, p < 0.0001).DiscussionStudy findings demonstrate disparities emerge at middles ages and worsen as age increases. This finding highlights the importance of addressing racial disparities in cognition across a larger part of the adult life course. By doing so, we may better be able to capture early-life exposures that influence later-life cognitive outcomes and ultimately lead to disparities.

“…However, it is demonstrated that trained clinicians can accurately judge self and/or informant reports on ADLs [ 29 ]. Nonetheless, since the most reported cause of limitations in ADLs is ‘old age’ [ 30 , 31 ], it is important that clinicians carefully explore the reasons of limitations by using probes such as ‘How do you/does (s)he performs this activity?’ or ‘What causes the need for help to perform this activity?’.…”

The Assessment of Activities of Daily Living (ADL) is paramount to ensure the accurate early diagnosis of neurocognitive disorders. Unfortunately, the most common ADL tools are limited in their use in a diagnostic process. Hence, we set out to validate a tool to evaluate basic (b-), instrumental (i-), and advanced (a-) ADL called the Brussels Integrated Activities of Daily Living Inventory (BIA). At the geriatric day hospital of the University Hospital Brussels (Belgium) older persons (65+) labelled as Cognitively Healthy Persons (CHP) (n = 47), having a Mild Cognitive Impairment (MCI) (n = 39), and having Alzheimer’s disease (AD) (n = 44) underwent a diagnostic procedure for neurocognitive disorders. Additionally, the BIA was carried out. An exploration using both (cumulative) logistic regressions and conditional inference trees aimed to select the most informative scales to discriminate between the HCP, persons with MCI and AD. The distinction between CHP and MCI and between MCI and AD was moderately successful with the i-ADLs, in addition to age. Therefore, it is advisable to conduct a multidomain assessment in which the i-ADL could serve as non-invasive and non-time-consuming screening, while the BIA might be useful for diagnostics and disease management.
