Objective: The Cambridge Cognitive Examination (CAMCOG) score is correlated with age and sociodemographic variables. The aim of the study was to determine an individualized CAMCOG cut-off score for dementia, taking such correlates into account.
Method: From the general population 150 people aged 65-84 years were examined with CAMDEX which includes CAMCOG, and a neuropsychological test battery. Data from 130 non-demented people were entered in setwise multiple regression analyses to identify variables predicting the CAMCOG score.
Results: The variables age, social class, matrimonial status, general knowledge and intellectual level explained 66% of the variance of the CAMCOG scores. A cut-off defined as a difference between actual and predicted CAMCOG score < or = -4.41 resulted in a sensitivity of 88.2% and a specificity of 89.2% for very mild to moderate dementia.
Conclusion: It is possible to determine an individualized CAMCOG cut-off score for dementia in its early stages.

Introduction: Cognitive decline is prevalent in maintenance hemodialysis patients. The blood-brain barrier has been implicated in cognitive decline. In this prospective cohort study, we investigated the associations between endothelium-related biomarkers and steeper cognitive decline in this population.

Background: Improved health care for people with Down syndrome (DS) has resulted in an increase in their life expectancy therefore increasing comorbidities associated with age-related problems in this population, the most frequent being Alzheimer's disease (AD). To date, several cognitive tests have been developed to evaluate cognitive changes related to the development of mild cognitive impairment (MCI) and AD in people with DS.
Objective: Identify and evaluate available cognitive tests for the diagnosis of MCI and AD in people with DS.

Background: Down syndrome (DS) is a genetic form of Alzheimer's disease (AD). However, clinical diagnosis is difficult, and experts emphasize the need for detecting intra-individual cognitive decline.
Objective: To compare the performance of baseline and longitudinal neuropsychological assessments for the diagnosis of symptomatic AD in DS.
