Background.To test the hypothesis that cognitive impairment in older adults is associated with all-cause mortality risk and the risk increases when the degree of cognitive impairment augments; and then, if this association is confirmed, to report the population-attributable fraction (PAF) of mortality due to cognitive impairment.Method.A representative random community sample of individuals aged over 55 was interviewed, and 4557 subjects remaining alive at the end of the first year of follow-up were included in the analysis. Instruments used in the assessment included the Mini-Mental Status Examination (MMSE), the History and Aetiology Schedule (HAS) and the Geriatric Mental State (GMS)-AGECAT. For the standardised degree of cognitive impairment Perneczky et al's MMSE criteria were applied. Mortality information was obtained from the official population registry. Multivariate Cox proportional hazard models were used to test the association between MMSE degrees of cognitive impairment and mortality risk. We also estimated the PAF of mortality due to specific MMSE stages.Results.Cognitive impairment was associated with mortality risk, the risk increasing in parallel with the degree of cognitive impairment (Hazard ratio, HR: 1.18 in the ‘mild’ degree of impairment; HR: 1.29 in the ‘moderate’ degree; and HR: 2.08 in the ‘severe’ degree). The PAF of mortality due to severe cognitive impairment was 3.49%.Conclusions.A gradient of increased mortality-risk associated with severity of cognitive impairment was observed. The results support the claim that routine assessment of cognitive function in older adults should be considered in clinical practice.

Abstract Background Cognitive impairment is commonly seen in traumatic brain injury survivors. Posttraumatic cognitive sequelae may be more devastating than focal motor and focal sensory deficits, and are usually left unattended. Aim and Objective Aim of this study was to assess cognitive impairment in patients who had sustained moderate degree diffuse axonal injuries and having good outcome (Glasgow Outcome Score of 5). Methods and Materials Prospective observational study was done from 2011 to 2015 on the patients who had sustained moderated degree diffuse brain injuries. Eighty-four cases fulfilling the inclusion criteria were studied. Patients were assessed with Mini-Mental Status Examination at discharge, end of 1 month, and at 3 months. Result Seventy-six were males and 8 were females. Age ranged from 16 to 49 years. Note that 4.76% (4) patients had hypotension at presentation, 32.14% (27) patients had associated injuries, and 19.04% (16) patients had hyponatremia at presentation. Diabetes mellitus was seen in 34.52% (29) patients, while hypertension was seen in 14.28% (12). At 3 months’ follow-up, 19.06% (16) patients had cognitive impairment. The present study revealed that hypotension and presence of associated injuries at presentation raises the odds of having cognitive impairment by 8 and 5 times, respectively. Conclusion Routine assessment of cognitive impairment in head injury survivors is essential as it may help in identifying cognitive deficits. Early intervention of neurorehabilitation to such patients results in better neurocognitive outcome. Hypotension and associated injuries are associated with poor cognitive outcome.

Aims.In a background of interest in staging models in psychiatry, we tested the validity of a simple staging model of cognitive impairment to predict incident dementia.Method.A large community sample of adults aged ≥55 years (N = 4803) was assessed in the baseline of a longitudinal, four-wave epidemiological enquiry. A two-phase assessment was implemented in each wave, and the instruments used included the Mini-Mental Status Examination (MMSE); the History and Aetiology Schedule and the Geriatric Mental State-AGECAT. For the standardised degree of cognitive impairment Perneczky et al's MMSE criteria were applied. A panel of psychiatrists diagnosed cases of dementia according to DSM-IV criteria, and cases and sub-cases of dementia were excluded for the follow-up waves. Competing risk regression models, adjusted by potential confounders, were used to test the hypothesised association between MMSE levels and dementia risk.Results.Out of the 4057 participants followed up, 607 (14.9%) were classified as ‘normal’ (no cognitive impairment), 2672 (65.8%) as ‘questionable’ cognitive impairment, 732 (18.0%) had ‘mild’ cognitive impairment, 38 (0.9%) had ‘moderate’ cognitive impairment and eight (0.2%) had ‘severe’ impairment.Cognitive impairment was associated with risk of dementia, the risk increasing in parallel with the level of impairment (hazard ratio: 2.72, 4.78 and 8.38 in the ‘questionable’, ‘mild’ and ‘moderate’ level of cognitive impairment, respectively).Conclusions.The documented gradient of increased risk of dementia associated with the severity level of cognitive impairment supports the validity of the simple staging model based on the MMSE assessment.

AUTHORS:Kerstin Johansson, Karolina Thömkvist, Ingmar Skoog and Sacuiu SF* (*presenter)OBJECTIVE:To determine the effects of electroconvulsive therapy (ECT) in major depression in relation to the development of dementia during long-term follow-up.METHOD:In an observational clinical prospective study of consecutive patients 70 years and older diagnosed with major depression at baseline 2000-2004 (n=1090), who were free of dementia and received antidepressant treatment, with or without ECT, we sought to determine if cognitive decline (mild cognitive impairment and dementia) during 15 -year follow-up was associated with receiving ECT at baseline. The control group was selected among the participants in the Gothenburg H70 Birth Cohort Studies matched by age group and sex 1:1.RESULTS:Among patients with affective syndromes 7% received ECT. During follow-up, 157 patients were diagnosed with dementia, equal proportions among those who received ECT (14.5%) and those who did not receive ECT (14.5%). The relation between ECT and cognitive decline remained non-significant irrespective antidepressive medication or presence of mild cognitive impairment at baseline.CONCLUSION:Preliminary results indicate that ECT was not associated with the development of cognitive decline in the long-term in a hospital-based cohort of 70+ year-olds. The results remain to verify against controls from a representative community sample.

Background: Although an efficacious dementia-risk score system, Cardiovascular Risk Factors, Aging, and Dementia (CAIDE) was derived using midlife risk factors in a population with low educational attainment that does not reflect today’s US population, and requires laboratory biomarkers, which are not always available. Objective: Develop and validate a modified CAIDE (mCAIDE) system and test its ability to predict presence, severity, and etiology of cognitive impairment in older adults. Methods: Population consisted of 449 participants in dementia research (N = 230; community sample; 67.9±10.0 years old, 29.6%male, 13.7±4.1 years education) or receiving dementia clinical services (N = 219; clinical sample; 74.3±9.8 years old, 50.2%male, 15.5±2.6 years education). The mCAIDE, which includes self-reported and performance-based rather than blood-derived measures, was developed in the community sample and tested in the independent clinical sample. Validity against Framingham, Hachinski, and CAIDE risk scores was assessed. Results: Higher mCAIDE quartiles were associated with lower performance on global and domain-specific cognitive tests. Each one-point increase in mCAIDE increased the odds of mild cognitive impairment (MCI) by up to 65%, those of AD by 69%, and those for non-AD dementia by >  85%, with highest scores in cases with vascular etiologies. Being in the highest mCAIDE risk group improved ability to discriminate dementia from MCI and controls and MCI from controls, with a cut-off of ≥7 points offering the highest sensitivity, specificity, and positive and negative predictive values. Conclusion: mCAIDE is a robust indicator of cognitive impairment in community-dwelling seniors, which can discriminate well between dementia severity including MCI versus controls. The mCAIDE may be a valuable tool for case ascertainment in research studies, helping flag primary care patients for cognitive testing, and identify those in need of lifestyle interventions for symptomatic control.

Abstract Objective Age-associated decline in central cholinergic activity makes older adults susceptible to harmful effects of anticholinergics (ACs). Evidence exists of an association between effects of AC medications on cognition. This retrospective cohort study examines how ACs affect cognition among older adults with Alzheimer’s disease (AD) who received acetylcholine esterase inhibitors (AChEIs) over the course of 12 months. Results A total of 133 (80% women, mean age 78.38 years, SD 7.4) were recruited. No difference in sex, age and comorbid diseases was observed between participants who took ACs, Benzodiazepines (BZDs) and AChEIs. The most common prescribed ACs was quetiapine, being used for behavioral and psychological symptoms (BPSD). Multilevel analysis showed that the change of mental state examination scores were significantly predicted in the group using ACs (t (169), -2.52, p = .020) but not with the groups using BZD (t (162), 0.84, p = .440). Evidence showed that older adults with Alzheimer’s disease and exposed to ACs exhibited lower global cognitive scores than those without AC exposure. Using ACs could be a trade-off between controlling BPSD and aggravating cognitive impairment. Highlighting the awareness of the potential anticholinergic effect is important and may be the best policy.

Background: The prevalence of varicose veins of small pelvic veins in women of reproductive age varies widely – from 5.4 to 80 %, due to the low specificity and low sensitivity of clinical diagnostic techniques, and the absence of biomarkers that can be used to identify the formation and progression of varicose veins of small pelvic veins in women.Aims: To identify changes in the levels of parameters of the system “lipid peroxidation – antioxidant protection” with the development of varicose veins of the pelvis in women, as well as the possibility of their diagnostic use.Materials and methods: We examined 200 women with clinical signs of varicose veins of small pelvis. Control group included 30 women without any pathology of venous system. Treatment group included 137 women with varicose veins of small pelvis: with mild degree of severity – 39 women, with moderate degree of severity – 65 women, with severe degree of severity – 33 women. We performed comparative analysis of lipid peroxidation – antioxidant defense system in women with and without varicose veins of small pelvis taking into account the severity degrees of pathological process.Results: We obtained the most informative indices for lipid peroxidation – antioxidant defense processes in blood of women with varicose veins of small pelvis: concentration of diene conjugate (DC) for the mild degree of severity of pathological process, lipid hydroperoxide (LHP), DC and malonic dialdehyde (MDA) – for the moderate and severe degree of severity, and also changes in the activity of antioxidant enzymes with increase of the severity of the disease. Assessment of the level of catalase (Cat) and glutathione peroxidase (GP) showed their highest informative value at the mild degree of severity. Concentrations of glutathione reductase (GR), glutathione S-transferase (GST) and reduced glutathione (GSH) are more statistically significant markers for severe forms of pathological process.Conclusions: Our research showed the relevance and advisability of the studying the levels of lipid peroxidation – antioxidant defense indices in women with varicose veins of small pelvis. We registered the highest diagnostic value of DC, Cat and GP in the beginning of the disease and of LHP, DC, MDA, GR, GST and GSH – at severe forms of the pathological process. We obtained reference values for DC, MDA, Cat, SOD and GP concentration that can be considered as the predictors of the development of varicose veins of small pelvis.

Background and Purpose: Research exploring the utility of cardiovascular health (CVH) and its Life’s Simple 7 (LS7) components (body mass index, blood pressure [BP], glucose, cholesterol, physical activity, smoking, and diet) for prevention of stroke in older adults is limited. In the British Regional Heart Study, we explored (1) prospective associations of LS7 metrics and composite CVH scores with, and their impact on, stroke in middle and older age; and (2) if change in CVH was associated with subsequent stroke. Methods: Men without cardiovascular disease were followed from baseline recruitment (1978–1980), and again from re-examination 20 years later, for stroke over a median period of 20 years and 16 years, respectively. LS7 were measured at each time point except baseline diet. Cox models estimated hazard ratios (95% CI) of stroke for (1) ideal and intermediate versus poor levels of LS7; (2) composite CVH scores; and (3) 4 CVH trajectory groups (low-low, low-high, high-low, high-high) derived by dichotomising CVH scores from each time point across the median value. Population attributable fractions measured impact of LS7. Results: At baseline (n=7274, mean age 50 years), healthier levels of BP, physical activity, and smoking were associated with reduced stroke risk. At 20-year follow-up (n=3798, mean age 69 years) only BP displayed an association. Hazard ratios for intermediate and ideal (versus poor) levels of BP 0.65 (0.52–0.81) and 0.40 (0.24–0.65) at baseline; and 0.84 (0.67–1.05) and 0.57 (0.36–0.90) at 20-year follow-up. With reference to low-low trajectory, the low-high trajectory was associated with 40% reduced risk, hazard ratio 0.60 (0.44–0.83). Associations of CVH scores weakened, and population attributable fractions of LS7 reduced, from middle to old age; population attributable fraction of nonideal BP from 53% to 39%. Conclusions: Except for BP, CVH is weakly associated with stroke at older ages. Prevention strategies for older adults should prioritize BP control but also enhance focus beyond traditional risk factors.

Abstract Background Technological advances have allowed a variety of computerized cognitive training tools to be engineered in ways that are fun and entertaining yet challenging at a level that can maintain motivation and engagement. This revolution has created an opportunity for gerontological scientists to evaluate brain gaming approaches to improve cognitive and everyday function. The purpose of this scoping review is to provide a critical overview of the existing literature on nonimmersive, electronic brain gaming interventions in older adults with mild cognitive impairment or dementia. Research Design and Methods Systematic search was conducted using 7 electronic databases from inception through July 2017. A comprehensive 2-level eligibility process was used to identify studies for inclusion based on PRISMA guidelines. Results Seventeen studies met eligibility criteria. Majority of the studies were randomized controlled trials (n = 13) and incorporated an active control (n = 9). Intervention doses ranged from 4 to 24 weeks in duration with an average of 8.4 (±5.1 standard deviation [SD]) weeks. Session durations ranged from 30 to 100 min with an average of 54 (±25 SD) minutes. Nearly half of studies included a follow-up, ranging from 3 months to 5 years (n = 8). For most studies, brain gaming improved at least one cognitive outcome (n = 12); only one study reported improvement in activities of daily living. Discussion and Implications This scoping review conveys the breadth of an emerging research field, which will help guide future research to develop standards and recommendations for brain gaming interventions which are currently lacking.

Abstract Background Multimorbidity is common among older adults and strongly associated with physical functioning decline and increased mortality. However, the full spectrum of direct and indirect effects of multimorbidity on physical functioning and survival has not been quantified. We aimed to determine the longitudinal relationship of multimorbidity on physical functioning and quantify the impact of multimorbidity and multimorbidity-attributed changes in physical functioning on mortality risk. Methods The Health and Retirement Study (HRS) is a nationally representative population-based prospective cohort of adults aged 51 or older. In 2000, participants were interviewed about physician-diagnosed chronic conditions, from which their multimorbidity-weighted index (MWI) was computed. Between 2000 and 2011, participants reported their current physical functioning using a modified Short Form-36. With MWI as a time-varying exposure, we jointly modeled its associations with physical functioning and survival. Results The final sample included 74,037 observations from 18,174 participants. At baseline, participants had a weighted mean MWI of 4.6 ± 4.2 (range 0–36.8). During follow-up, physical functioning declined: −1.72 (95% confidence interval [CI] −1.77, −1.67, p < .001) HRS physical functioning units per point MWI in adjusted models. Over follow-up, 6,362 (34%) participants died. Mortality risk increased 8% (hazard ratio 1.08, 95% CI 1.07–1.08, p < .001) per point MWI in adjusted models. Across all population subgroups, MWI was associated with greater physical functioning decline and mortality risk. Conclusions Multimorbidity and its associated decline in physical functioning were significantly associated with increased mortality. These associations can be predicted with an easily interpreted and applied multimorbidity index that can better identify and target adults at increased risk for disability and death.
