Cued recall and other cognitive tasks to facilitate dementia recognition in primary care
Objectives: To compare the accuracy of commonly used tasks with that of the Visual Association Test (VAT), a conceptually different test involving cued recall of pictorial stimuli, in the recognition of dementia within primary care.; Design: A cross-sectional diagnostic study of concurrent validity.; Setting: Twenty-nine German primary care practices.; Participants: Four hundred twenty-three individuals in […]

Legrain, S.,
Dubois, B.
Objectives: The aim of the Pre-Al study is to evaluate and compare the predictive value of different tools for an early identification of Alzheimer’s disease.; Design and Participants: Patients coming for consultation to memory clinics without dementia were included if they had an objective memory or attention trouble assessed by a MMSE score > 25 […]

Cardiovascular risk factors increase the risk of dementia in later life. The aims of the current study were to assess the effect of multiple midlife cardiovascular risk factors on the risk of cognitive impairment in later life, and to assess the validity of the previously suggested CAIDE Study risk score predicting dementia risk 20 years later. […]
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) […]

Mackenzie, Ellen J.
Objective: The aim of this study was to develop and validate a comorbidity index to predict the risk of mortality associated with chronic health conditions following a traumatic injury.; Summary Background Data: Currently available comorbidity adjustment tools do not account for certain chronic conditions, which may influence outcome following traumatic injury or they have not […]

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 […]

Purpose: assess psychometric properties of scales developed to assess experience and perception of physical, psychological, and existential suffering in older individuals.; Design and Methods: scales were administered to 3 populations of older persons and/or their family caregivers: individuals with Alzheimer’s disease (AD) and their family caregivers (N = 105 dyads), married couples in whom 1 […]

Background: Although the association between cytosine-adenine-guanine (CAG) repeat length and age at onset of Huntington’s disease is well known, improved prediction of onset would be advantageous for clinical trial design and prognostic counselling. We compared various measures for tracking progression and predicting conversion to manifest Huntington’s disease.; Methods: In this prospective observational study, we assessed […]
