Accuracy of the Short-Form Montreal Cognitive Assessment Chinese Versions.

There is a strong need for short and effective methods to screen for cognitive impairment. Recent studies have created short forms of the Montreal Cognitive Assessment (s-MoCA) in English-speaking populations. It is also important to develop a validated Chinese short version to detect cognitive impairment.

The Epoch Effect on Cognitive Function Requires Regular Updating of Cognitive Screening Tests.

Background: Over time, improved cognitive abilities in elderly individuals lead to an overall increase in performance on widely used cognitive screening tests (e.g., Mini-Mental State Examination, MMSE) and impact screening efficacy.

The impact of methods to handle missing data on the estimated prevalence of dementia and mild cognitive impairment in a cross-sectional study including non-responders.

Objective: Although several statistical methods for adjusting for missing data have been developed and are widely applied in research, few studies have investigated these methods in adjusting for missingness in datasets that aim to estimate the prevalence of dementia. We attempted to develop a more feasible approach for handling missingness in a cross-sectional study among elderly.

Methods: Five methods of estimating prevalence, including stratified weighting (SW), inverse-probability weighting (IPW), hot deck imputation (HDI), ordinal logistic regression (OLR) and multiple imputation (MI), were applied to handle the missing data yielded by a dataset that include 2231 non-responders.

Characteristics of participants' and caregivers' influence on non-response in a cross-sectional study of dementia in an older population.

Objective: The issue of non-response in dementia epidemiological studies, which may result in the underestimation of the prevalence of dementia, has attracted little attention. We aimed to explore the causes and related factors of non-response in a dementia survey among Chinese veterans.

Methods: A two-phase, cross-sectional study investigated the prevalence of dementia and mild cognitive impairment in Chinese veterans aged ≥ 60 years.

Awareness Status of Chronic Disabling Neurological Diseases among Elderly Veterans.

Background: The awareness, treatment and prevention of chronic diseases are generally poor among the elderly population of China, whereas the prevention and control of chronic diseases in elderly veteran communities have been ongoing for more than 30 years. Therefore, investigating the awareness status of chronic disabling neurological diseases (CDND) and common chronic diseases (CCD) among elderly veterans may provide references for related programs among the elderly in the general population.

Methods: A cross-sectional survey was conducted among veterans ≥60 years old in veteran communities in Beijing.

Physical activity as a protective factor against depressive symptoms in older Chinese veterans in the community: result from a national cross-sectional study.

Background: Physical activity is generally considered to be effective in reducing the prevalence of depression and promoting remission of its symptoms. However, large-scale epidemiological research on this issue is lacking in older Chinese adults. We performed a nationwide epidemiological survey to determine the relationship between physical activity and depressive symptoms in older Chinese veterans in the community, with adjustment for potential confounders.

Optimal cutoff scores for dementia and mild cognitive impairment of the Montreal Cognitive Assessment among elderly and oldest-old Chinese population.

Background: All versions of the Montreal Cognitive Assessment (MoCA) lack population-based data of 80-plus individuals. The norms and cut-off scores for mild cognitive impairment (MCI) and dementia of the MoCA are different among five Chinese versions.

Objective: To provide the cut-off scores in detecting MCI and dementia of the Peking Medical Union College Hospital version of the MoCA (MoCA-P).

Burden, anxiety and depression in caregivers of veterans with dementia in Beijing.

Dementia is the most common neurodegenerative disease in the elderly. The number of Chinese dementia patients reached 5 million in 2001 and will grow rapidly by 314-336% in 2040. Caring for patients with dementia is a stressful experience, which can cause the physical and mental problems in caregivers.

[A cross-sectional study of neurological disease in the veterans of military communities in Beijing].

Objective: To investigate the prevalence of cognitive and motor disorders as well as emotional and sleep abnormality in the veterans from military communities in Beijing.

Methods: The participants underwent a comprehensive in-person evaluation including detailed neuropsychological testing, Hospital Anxiety and Depression Scale and special questionnaires for movement and sleep disorders.

Results: The overall prevalence of cognitive impairment, extrapyramidal diseases was 32.

Cognitive stimulation therapy in the treatment of neuropsychiatric symptoms in Alzheimer's disease: a randomized controlled trial.

Objective: to determine the efficacy of cognitive stimulation therapy (CST) in the treatment of neuropsychiatric symptoms in patients with Alzheimer's disease.

Design: a randomized, controlled, rater-blind clinical trial.

Setting: the military sanatorium.

[A case-control study of risk factors in mild cognitive impairment].

Objective: To explore the risk factors of mild cognitive impairment (MCI).

Methods: A case-control study including 97 MCI patients and 143 cognitive normal controls (NC) in Chinese PLA General Hospital was conducted. The cases and controls were matched for age, gender and occupation.
