Prevalence of Cognitive Impairment Without Dementia and Dementia in Tremembé, Brazil.

Background: The prevalence of cognitive impairment is insufficiently determined in developing countries. The aim of this study was to ascertain the prevalence of cognitive impairment without dementia and dementia in community-dwelling elderly in Brazil.

Methods: This was a single-phase cross-sectional survey of the elderly (aged 60 years and above) living in the municipality of Tremembé, Brazil.

Brain metabolism and cerebrospinal fluid biomarkers profile of non-amnestic mild cognitive impairment in comparison to amnestic mild cognitive impairment and normal older subjects.

Introduction: Mild cognitive impairment (MCI) is classically considered a transitional stage between normal aging and dementia. Non-amnestic MCI (naMCI) patients, however, typically demonstrate cognitive deficits other than memory decline. Furthermore, as a group, naMCI have a lower rate of an eventual dementia diagnosis as compared to amnestic subtypes of MCI (aMCI).

Effects of Aerobic Training on Cognition and Brain Glucose Metabolism in Subjects with Mild Cognitive Impairment.

Background: Aerobic training (AT) is a promising intervention for mild cognitive impairment (MCI).

Objective: To evaluate the effects of AT on cognition and regional brain glucose metabolism (rBGM) in MCI patients.

Methods: Subjects performed a twice-a-week, moderate intensity, AT program for 24 weeks.

Performance of the Visual Analogue Scale of Happiness and of the Cornell Scale for Depression in Dementia in the Tremembé Epidemiological Study, Brazil.

Unlabelled: Depression is a major growing public health problem. Many population studies have found a significant relationship between depression and the presence of cognitive disorders.

Objective: To establish the correlation between the Visual Analogue Scale of Happiness and the Cornell Scale for Depression in Dementia in the population aged 60 years or over in the city of Tremembé, state of São Paulo, Brazil.

Prevalence of depressive symptoms among elderly in the city of Tremembé, Brazil: preliminary findings of an epidemiological study.

Unlabelled: Depression is a heterogeneous mental disease classified as a set of disorders, which manifest with a certain duration, frequency and intensity. The prevalence of depression in the elderly ranges from 0.5 to 16%.

Comparison of performance in neuropsychological tests in amnestic Mild Cognitive Impairment and Alzheimer's disease patients.

Unlabelled: Mild Cognitive Impairment (MCI) can be an intermediate state between normality and dementia in some patients. An early diagnosis, through neuropsychological assessment, could identify individuals at risk of developing dementia.

Objective: To verify differences in performance on neuropsychological tests among controls, amnestic MCI (aMCI) and Alzheimer's disease (AD) patients.
