“…However, our i-ADL-DI and i-ADL-CDI show similar accurate validity to discriminate between HC, MCI, and AD. So, although this study developed a report-based measure—which may not be as accurate in detecting functional difficulties in persons with mild cognitive decline—the results of this study indicate that the ICF-based evaluation of b- and i-ADL might compete with the recently developed performance-based tools as the standard for classifying functional status and decline [32,33,55,94]. Ongoing research will clarify this and is already assessing the convergent validity between the ICF-based evaluation of b- and i-ADL and a performance-based measure.…”

“…However, only few of them are developed to assess MCI or mild dementia [55,93], and they are mostly too time- and cost-consuming to be administered [9,31]. Two recent performance-based instruments, the Erlangen Test of Activities of Daily Living in Mild Dementia or Mild Cognitive Impairment (ETAM) [55] and the Sydney Test of Activities of Daily Living in Memory Disorders (STAM) [94] have been developed with the aim to assess everyday activities in a time-efficient and reliable way for persons with MCI or mild dementia. Both evaluations show good psychometric characteristics, are easy to administer, and seem to be valuable in clinical practice and research.…”

Early diagnosis of mild cognitive impairment and mild dementia through basic and instrumental activities of daily living: Development of a new evaluation tool

BackgroundAssessment of activities of daily living (ADL) is paramount to determine impairment in everyday functioning and to ensure accurate early diagnosis of neurocognitive disorders. Unfortunately, most common ADL tools are limited in their use in a diagnostic process. This study developed a new evaluation by adopting the items of the Katz Index (basic [b-] ADL) and Lawton Scale (instrumental [i-] ADL), defining them with the terminology of the International Classification of Human Functioning, Disability and Health (ICF), adding the scoring system of the ICF, and adding the possibility to identify underlying causes of limitations in ADL.Methods and findingsThe construct validity, interrater reliability, and discriminative validity of this new evaluation were determined. From 2015 until 2016, older persons (65–93 y) with normal cognitive ageing (healthy comparison [HC]) (n = 79), mild cognitive impairment (MCI) (n = 73), and Alzheimer disease (AD) (n = 71) underwent a diagnostic procedure for neurocognitive disorders at the geriatric day hospital of the Universitair Ziekenhuis Brussel (Brussels, Belgium). Additionally, the ICF-based evaluation for b- and i-ADL was carried out. A global disability index (DI), a cognitive DI (CDI), and a physical DI (PDI) were calculated. The i-ADL-CDI showed high accuracy and higher discriminative power than the Lawton Scale in differentiating HC and MCI (area under the curve [AUC] = 0.895, 95% CI .840–.950, p = .002), MCI and AD (AUC = 0.805, 95% CI .805–.734, p = .010), and HC and AD (AUC = 0.990, 95% CI .978–1.000, p < .001). The b-ADL-DI showed significantly better discriminative accuracy than the Katz Index in differentiating HC and AD (AUC = 0.828, 95% CI .759–.897, p = .039). This study was conducted in a clinically relevant sample. However, heterogeneity between HC, MCI, and AD and the use of different methods of reporting ADL might limit this study.ConclusionsThis evaluation of b- and i-ADL can contribute to the diagnostic differentiation between cognitively healthy ageing and neurocognitive disorders in older age. This evaluation provides more clarity and nuance in assessing everyday functioning by using an ICF-based terminology and scoring system. Also, the possibility to take underlying causes of limitations into account seems to be valuable since it is crucial to determine the extent to which cognitive decline is responsible for functional impairment in diagnosing neurocognitive disorders. Though further prospective validation is still required, the i-ADL-CDI might be useful in clinical practice since it identifies impairment in i-ADL exclusively because of cognitive limitations.

“…The advantages and limitations of report-based and performance-based measures have led to discussions regarding the most suitable method for evaluating ADLs. Currently, there is no gold standard that is time efficient and easy to administer (Reppermund et al, 2016). Only a limited number of studies have compared report-based and performance-based measures in the same sample of older persons and have found limited correlations between the two measures (Schmitter-Edgecombe et al, 2014;Rycroft et al, 2017).…”

“…Several factors in patients with dementia have been associated with impairments in ADL, including cognitive status [5][6][7][8][9], education [9], and white matter hyperintensities (WMHs) [10]. In addition, motor and gait performance have been shown to predict performance of higher-level functioning tasks among the elderly [11].…”

ObjectiveTo compare daily functional performance and potential predictive factors in patients with Alzheimer's disease (AD) and subcortical ischemic vascular disease (SIVD). MethodsSixty-eight community patients with AD and 39 with SIVD were evaluated using the informantbased Barthel Index of Activities of Daily Living (B-ADL) and Instrumental Activities of Daily Living (IADL). Motor function, cognition, and white matter hyperintensities (WMHs) were assessed using the modified Rankin Scale (mRS), Cognitive Abilities Screening Instrument (CASI)/Clinical Dementia Rating (CDR), and Scheltens scale, respectively. ResultsAfter controlling for systemic diseases and medications, toilet use was the only B-ADL subset in which the patients with SIVD performed worse than those with AD in overall comparisons and CDR0.5-1. Additionally, the SIVD group with CDR0.5-1 performed worse in bathing, mobility, and climbing stairs. Regarding IADL performance, the SIVD group had worse performances than the AD group in mode of transportation during CDR2. In WMHs analysis, periventricular WMHs (PWMHs) was the only factor showing significant inverse correlations with both CASI and B-ADL/IADL. Hierarchical regression of all patients suggested that the best models including age, education, PWMHs, CASI, and mRS accounted for 71% and 78% of the variances in B-ADL and IADL, respectively. While mRS accounted for a significant effect in both B-ADL and IADL, CASI accounted for a significant effect only in IADL. Subgroup analysis suggested that the effects of CASI and PWMHs were confined within B-ADL/IADL and IADL in the AD group, respectively. ConclusionsMotor function was the major factor in both B-ADL and IADL, and cognition had a significant effect on IADL. Although PWMH load had inverse associations with both motor and cognitive functions, this radiological marker better predicted IADL in AD than in SIVD. The variation in daily functional profiles with dementia stage and subtypes highlights the need to assess motor function for preventive interventions.

However, the functional profiles and determining factors in individuals with SIVD have yet to be fully elucidated [18][19][20], and comparisons of these two prevalent subtypes of dementia are even more limited [19][20]. Therefore, the aims of the current study were to compare the profiles of ADL performance between patients with SIVD and AD subtypes, and to analyze predictors of daily functional performance in different subtypes of dementia by examining the associations between clinical factors, cognitive/motor function, and WMHs. Materials and MethodsSixty-eight community patients with AD and 39 with SIVD who visited the...
