OBJECTIVES To develop and validate a psychometrically rigorous measure of health-related quality of life (HRQoL) for people with dementia: DEMQOL. DATA SOURCES Literature review. Expert opinion. Interviews and questionnaires. REVIEW METHODS Gold standard psychometric techniques were used to develop DEMQOL and DEMQOL-Proxy. A conceptual framework was generated from a review of the literature...

Aims The present study set out to evaluate the psychometric properties of the Cognitive Telephone Screening Instrument (COGTEL) in 2 different samples of older adults. Methods We assessed COGTEL in 116 older adults, with retest after 7 days to evaluate the test-retest reliability. Moreover, we assessed COGTEL in 868 older adults to evaluate convergent validity to the Mini-Mental State Examina...

The increase in life expectancy can influence the prevalence of dementias in the population. Instruments that evaluate cognitive functions such as the Mini Mental State Examination (MMSE) are necessary for the investigation of dementia. The supposition that patient score on the MMSE can be influenced by academic level points to the need for establishing cut-off values that take into account edu...

BACKGROUND Mild cognitive impairment is a recently described neuropsychiatric entity with the possibility of evolving into overt dementia. It has been found to respond to therapeutic intervention, thus halting or significantly retarding the progression to dementia. Resource-poor countries like Nigeria can hardly afford to provide optimal care for dementia patients. Knowledge about mild cognitiv...

OBJECTIVE to investigate the association between gait speed and the cognitive score of elderly patients enrolled in a Basic Health Unit. METHOD a quantitative cross-sectional study with 203 elderly, a sample calculated based on the estimated population proportion. Data were collected using a sociodemographic and clinical questionnaire, gait speed test (GS) and the Mini Mental State Examinatio...

BACKGROUND the terminal decline hypothesis suggests an acceleration in the rate of loss of cognitive function before death. Evidence about the association of educational attainment and the onset of terminal decline is scarce. OBJECTIVE to investigate the association of education with the onset of terminal decline in global cognitive function measured by Mini Mental State Exam (MMSE) scores. ...

INTRODUCTION The cognitive functions in adults can be altered by a number of diseases, nutritional deficiencies, hormonal changes, ageing and drugs. Anaemia, through various possible mechanisms, has been suggested to result in a cognitive deterioration. AIM AND OBJECTIVE To study the effect of Hb% on cognitive skills of 100 UG medical students of Sree Balaji Medical College and Hospital, Chro...

[Purpose] The purpose of this study was to evaluate the lower limb muscle strength of the community-dwelling elderly, with or without cognitive decline, using isometric knee extension strength (IKES) and the 30-second chair stand test (CS-30). [Subjects] A total of 306 community-dwelling elderly participated in this study. Assessment items were the CS-30, IKES, Mini-Mental State Examination (MM...

BACKGROUND The dual-task performance is associated with the functionality of the elderly and it becomes more complex with age. OBJECTIVE To investigate the relationship between the Timed Up and Go dual task (TUG-DT) and cognitive tests among elderly participants who exercise regularly. METHOD This study examined 98 non-institutionalized people over 60 years old who exercised regularly. Part...

The aim of this study was to estimate the association between contextual income and cognitive decline in the elderly in Florianópolis, a medium-sized city in southern Brazil. A nested cross-sectional study was performed in a cohort of elderly ≥ 60 years (n = 1,197), interviewed in the second wave (2013/2014) of the EpiFloripa cohort. Cognitive decline was assessed with the Mini Mental State Exa...
