Assessment of judgment ability in a Brazilian sample of patients with mild cognitive impairment and dementia.

Unlabelled: Judgment is the ability to make sound decisions after consideration of relevant information, possible solutions, likely outcomes, and contextual factors. Loss of judgment is common in patients with mild cognitive impairment (MCI) and dementia. The Test of Practical Judgment (TOP-J) evaluates practical judgment in adults and the elderly, with 15- and 9-item versions that require individuals to listen to scenarios about everyday problems and report their solutions.

Alpha band EEG coherence in healthy nonagenarians.

Objective: Electroencephalographic (EEG) coherence is a parameter that enables evaluation of cerebral connectivity. It may be related to the functional state of the brain. In the elderly, it may reflect the neuronal loss caused by aging.

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.

Paraneoplastic limbic encephalitis with prominent neuropsychiatric apathy.

The spectrum of paraneoplastic neurologic syndromes has increased with the description of encephalitis associated with antibodies against cell surface and synaptic proteins. Subacute cognitive impairment, movement disorders, late onset epilepsy and neuropsychiatric syndromes were recently linked to paraneoplastic encephalitis. Despite that, probably some syndromes and antibodies are yet to be reported.

A score based on screening tests to differentiate mild cognitive impairment from subjective memory complaints.

It is not easy to differentiate patients with mild cognitive impairment (MCI) from subjective memory complainers (SMC). Assessments with screening cognitive tools are essential, particularly in primary care where most patients are seen. The objective of this study was to evaluate the diagnostic accuracy of screening cognitive tests and to propose a score derived from screening tests.

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%.

Prospective memory in Alzheimer's disease and Mild Cognitive Impairment.

Prospective memory (PM) is defined as remembering to carry out intended actions at an appropriate point in the future, and can be categorized into three types of situation: time-, event-, and activity-based tasks. PM involves brain structures such as frontal and medial temporal cortices. The aim of this study was to review the currently available literature on PM in Alzheimer's disease and Mild Cognitive Impairment patients.

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.
