Neuroimaging predictors of brain amyloidosis in mild cognitive impairment
Objective: To identify a neuroimaging signature predictive of brain amyloidosis as a screening tool to identify individuals with mild cognitive impairment (MCI) that are most likely to have high levels of brain amyloidosis or to be amyloid-free.; Methods: The prediction model cohort included 62 MCI subjects screened with structural magnetic resonance imaging (MRI) and (11) […]
The Nottingham Health Profile: a feasible questionnaire for nursing home residents?
Background: The Nottingham Health Profile (NHP) assesses perceived emotional, social, and physical health problems and the extent to which such problems affect daily activities. The objective of our study was to determine the feasibility of the NHP for nursing home residents.; Methods: A prospective multicenter observational study was conducted in 11 nursing homes from April […]

Background: Neuropsychological tests, including tests of language ability, are frequently used to differentiate normal from pathological cognitive aging. However, language can be particularly difficult to assess in a standardized manner in cross-cultural studies and in patients from different educational and cultural backgrounds. This study examined the effects of age, gender, education and race on performance […]
Psychometric evaluation of the Swedish version of the Person-Centered Care Assessment Tool (P-CAT)
Background: Person-centered care is a multidimensional concept describing good care, especially within aged care and care for people with dementia. Research studies evaluating person-centered care interventions seldom use direct measurement of levels of person-centeredness. Existing scales that measure person-centeredness need further testing. This study evaluated the psychometric properties of the Swedish version of the Person-Centered […]

Unlabelled: Evaluating the symptomatic progression of mild cognitive impairment (MCI) caused by Alzheimer disease (AD) is practically accomplished by tracking performance on cognitive tasks, such as the Alzheimer Disease Assessment Scale’s cognitive subscale (ADAS_cog), the Mini-Mental Status Examination (MMSE), and the Functional Activities Questionnaire (FAQ). The longitudinal relationships between cognitive decline and metabolic function as […]

The close correlation between abnormally low pre-mortem cerebrospinal fluid (CSF) concentrations of amyloid-β1-42 (Aβ(1-42)) and plaque burden measured by amyloid imaging as well as between pathologically increased levels of CSF tau and the extent of neurodegeneration measured by MRI has led to growing interest in using these biomarkers to predict the presence of AD plaque […]
