BackgroundEarly diagnosis of dementia requires knowledge about associated predictors. The aim of this study was to determine the impact of mild cognitive impairment (MCI) and impairment in instrumental activities of daily living (IADL) on the time to an incident dementia diagnosis.MethodData were derived from the Leipzig Longitudinal Study of the Aged (LEILA75+), a population-based study of individuals aged ⩾75 years. Kaplan-Meier survival analysis was used to determine time to incident dementia. Cox proportional hazards models were applied to determine the impact of MCI and IADL impairment on the time to incident dementia.ResultsIn total, 180 (22.0%) of 819 initially dementia-free subjects developed dementia by the end of the study. Mean time to incident dementia was 6.7 years [95% confidence interval (CI) 6.5–6.9]. MCI combined with IADL impairment was associated with a higher conversion rate to dementia, a shorter time to clinically manifest diagnosis and a lower chance of reversibility to cognitive normal. The highest risk for a shorter time to incident dementia was found for amnestic MCI combined with IADL impairment. The mean time to incident dementia was 3.7 years (95% CI 2.9–4.4) and thus half as long as in subjects without MCI and IADL impairment.ConclusionsSubjects with MCI and IADL impairment constitute a high-risk population for future dementia. The consideration of both – MCI and IADL impairment – might help to improve the prediction of dementia.

Abstract Mild Cognitive Impairment is characterized as an intermediate form between age-related change and dementia. For the elderly, autonomy and independence are related to the ability to remain active in conducting their social activities and, for this to occur, communication is fundamental in this process. Objective: To assess the association between communication and the abilities of elderly people with mild cognitive impairment to perform instrumental activities of daily living. Methods: A cross-sectional, quantitative, analytical, correlational study was conducted at the Open University of the Third Age (UnATI), a program of the Federal University of Pernambuco. This study included 92 people, comprising 46 elderly with mild cognitive impairment and a caregiver or family member who met the inclusion criteria. The elderly were asked to complete a sociodemographic questionnaire and Lawton-Brody’s Instrumental Activities of Daily Living Scale. The caregivers were asked to complete the Functional Assessment of Communication Skills. The following variables were studied: social communication skills and instrumental activities of daily living. Data were stored in an Excel® 2007 spreadsheet, and the Pearson correlation test was used for the statistical analysis. Results: There were statistically significant correlations in four domains of social communication: referring to family members by name (p=0.0033); requesting information about people or events (p=0.0355); understanding conversations in a noisy environment (p=0.0448); and understanding what they watch on television or listen to on the radio (p=0.0127). Conclusion: Changes in the communication of elderly people with mild cognitive impairment interfere with their ability to perform instrumental activities autonomously and independently.

Purpose: The purpose of this study was to identify factors affecting reversion to normal cognition and progression to dementia from mild cognitive impairment (MCI) after 2 years.Methods: We analyzed data from the 6th and 7th “Korean Longitudinal Study of Ageing (KLoSA)”. A total of 773 participants aged 65 years and above classified as having MCI according to the Korean Mini-Mental State Examination in the 6th survey were included in the study. Data were analyzed by SPSS 26.0 software using x2 test, t-test, Mann-Whitney test and logistic regression analysis.Results: Of all the participants, 30.5% reverted to normal cognition, 48.5% remained with MCI, and 21.0% progressed to dementia. Factors such as young age (odds ratio [OR]=0.96, 95% confidence interval [CI]: 0.94~0.99), the absence of diabetes (OR=1.49, 95% CI: 1.01~2.19), and frequent neighbor networks “at least once or twice a month” (OR=2.35, 95% CI: 1.26~4.37), and “at least once a week” (OR=1.63, 95% CI: 1.03~2.56) compared to “never or less than 6 times a year” significantly associated with reversion to normal cognition. Meanwhile, factors such as old age (OR=1.09, 95% CI: 1.05~1.12), low level of perceived socioeconomic status (reference. above middle) (OR=1.59, 95% CI: 1.05~2.41), low levels of instrumental activities of daily living (OR=1.17, 95% CI: 1.05~1.32), and a small number of social activities (OR=0.70, 95% CI: 0.51~0.96) significantly associated with dementia progression.Conclusion: The study indicates the necessity of follow-up research for developing interventions that could aid individuals in reverting to normal cognitive function by managing diabetes or encouraging interaction with neighbors and preventing the progression to dementia by improving Instrumental Activities of Daily Living levels or encouraging participation in social activities.

Background: Previous cross-sectional studies suggest that assessments of instrumental activities of daily living (IADLs) may be useful for operationalizing the differences in functional deficits seen in mild cognitive impairment (MCI) and dementia. However, their utility for longitudinal changes in IADLs in the transition between MCI and dementia remains unclear. Methods: We analyzed longitudinal IADL data with the Functional Activities Questionnaire (FAQ) in stable (MCI-S; n = 1,318) or progressive (MCI-P; n = 1,108) MCI patients. Results: Larger increases in FAQ scores were seen in the MCI-P group across a 14.5-month interval, but overlapping distributions in the two groups yielded poorer discriminatory power than prior cross-sectional reports. Conclusion: Our findings emphasize the difficulties in operationalizing the criterion of ‘essentially intact' IADLs in MCI, which may complicate the interpretation of disease progression in MCI treatment trials. © 2014 S.
