Cognitive dysfunction commonly occurs among older patients during admission and is associated with adverse prognosis. This study evaluated clinical characteristics and outcome determinants in hospitalized older patients with cognitive disorders. The main outcomes were length of stay, readmission within 30 days, Barthel index (BI) score at discharge, BI score change (discharge BI score minus BI score), and proportion of positive BI score change to indicate change of activities of daily living (ADL) change during hospitalization. A total of 642 inpatients with a mean age of 79.47 years (76–103 years) were categorized into three groups according to the medical history of dementia, and Mini-Mental State Examination (MMSE) scores at admission. Among them, 74 had dementia diagnosis (DD), 310 had cognitive impairment (CI), and 258 had normal MMSE scores. Patients with DD and CI generally had a higher risk of many geriatric syndromes, such as multimorbidities, polypharmacy, delirium, incontinence, visual and auditory impairment, fall history, physical frailty. They had less BI score, BI score change, and proportion of positive BI score change ADL at discharge. (DD 70.0%, CI 79.0%), suggesting less ADL change during hospitalization compared with those with normal MMSE scores (92.9%; p < 0.001). Using multiple regression analysis, we found that among patients with DD and CI, age (p = 0.008) and walking speed (p = 0.023) were predictors of discharge BI score. In addition, age (p = 0.047) and education level were associated with dichotomized BI score change (positive vs. non-positive) during hospitalization. Furthermore, the number and severity of comorbidities predicted LOS (p < 0.001) and readmission (p = 0.001) in patients with cognitive disorders. It is suggested that appropriate strategies are required to improve clinical outcomes in these patients.

AbstractFrailty is considered a multidimensional geriatric syndrome, manifested by the accumulation of age-associated deficits. The consequences of frailty transitions are still understudied. This study evaluated the influence of frailty transitions on cognitive function in the older adult population. We used data derived from the Korean Longitudinal Study of Aging (KLoSA) (2008–2018) on older adults aged ≥ 65 years. Frailty was assessed using a validated Korean frailty measure known as the frailty instrument (FI), and cognitive function was measured using the Korean version of the Mini-Mental State Examination (K-MMSE). Transitions in frailty and their relationship with cognitive function were investigated using lagged generalized estimating equations (GEE), t-tests, and ANOVA. Respondents who experienced frailty transitions (those with ameliorating frailty), those who developed frailty, and whose frailty remained constant, were more likely to have a lower cognitive function than those who were consistently non-frail. Older age, activities of daily living (ADL) disability, and instrumental ADL disability were more negatively associated with declining cognitive function, especially in the “frail → frail” group. Changes in all individual components of the frailty instrument were significantly associated with impaired cognitive function. The results suggest an association between frailty transitions and cognitive impairment. Over a 2-year span, the remaining frail individuals had the highest rate of cognitive decline in men, while the change from non-frail to frail state in women was significantly associated with the lowest cognitive function values. We recommend early interventions and prevention strategies in older adults to help ameliorate or slow down both frailty and cognitive function decline.

Abstract Background Cognitive dysfunction in idiopathic interstitial pneumonia (IIP) is an important clinical co-morbidity that is associated with impaired lung function. The aim of the work is to assess cognitive function in major IIP and to find out the relation between cognitive dysfunction and the oxygenation parameters. Results Fifty individuals were involved in the study; 30 patients with major IIP and 20 healthy individuals. Patients with IIP had significantly lower mini mental state examination (MMSE) score compared to the control group (P < 0.001). Wechsler Deterioration Index (WDI) revealed that 33.3% (n = 10) of the patients with IIP had sure cognitive impairment and 26.6% (n = 8) had ongoing cognitive deterioration. Patients with idiopathic pulmonary fibrosis (IPF) had lower cognitive function than other IIP. Conclusion There is an impairment of cognitive function in patients with major IIP, particularly in IPF, as measured by WDI and MMSE. Further large studies are needed to assess the possible predictors of cognitive impairment and their effects on the patients’ outcome.

The purpose of the study. To study clinical and neuroimaging features of chronic cerebral ischemia (CCI) in polycythemia vera (PV).Materials and methods. 66 patients with PV were examined – the main group (43 men, 23 women; mean age 62.0 ± 3.4 years), of which 64 (97.0%) patients were diagnosed with CCI. The comparison group consisted of 85 patients with CCI (34 men, 51 women; mean age 67.7 ± 4.6 years), who developed against the background of cerebral vascular atherosclerosis and arterial hypertension. To identify cognitive disorders, we used Mini Mental State Examination (MMSE). Insomnia was studied in accordance with the criteria of the International Classification of Sleep ICDS‑22005. The quality of sleep was determined using a questionnaire from the Federal Somnological Center. Neuroimaging (MRI of the brain) was performed on Siemens Symphony 1.5 T and GE Signa 1.5 T tomographs.Results. Subjective symptoms CCI are characterized by a greater representation of asthenic and insomniac disorders. Transient ischemic attacks in patients with PV are significantly more common than in the comparison group, their frequency depends on the duration of PV. The revealed changes in MRI of the brain in the majority of PV patients with CCI are characteristic of multiinfarction vascular encephalopathy; in the comparison group, changes that characteristic for subcortical arteriosclerotic encephalopathy were more often recorded.

Abstract BACKGROUND We investigated the association between atrophy subtypes of Alzheimer’s disease (AD), the ATN classification scheme, and key demographic and clinical factors, in two cohorts with different source characteristics (a highly selective research-oriented cohort, ADNI; and a naturalistic heterogeneous clinically-oriented cohort, Karolinska Imaging Dementia Study (KIDS). METHODS A total of 382 AD patients were included. Factorial analysis of mixed data was used to investigate associations between AD subtype based on brain atrophy patterns, ATN profiles based on cerebrospinal fluid biomarkers, and age, sex, Mini Mental State Examination (MMSE), cerebrovascular disease (CVD) (burden of white matter signal abnormalities, WMSA), and APOE genotype. RESULTS Older patients with high WMSA burden, belonging to the typical AD subtype, and showing A + T + N + or A + T + N- profiles clustered together and were mainly from ADNI. Younger patients with low WMSA burden, limbic-predominant or minimal atrophy AD subtypes, and A + T-N- or A + T-N + profiles, clustered together and were mainly from KIDS. APOE ε4 carriers more frequently showed the A + T-N- and A + T + N- profiles. CONCLUSIONS Our findings align with the recent framework for biological subtypes of AD: the combination of risk factors, protective factors, and brain pathologies determines belonging of AD patients to distinct subtypes.

Abstract In the context of a rapidly ageing Chinese population, this study aims to examine trends in the prevalence of cognitive impairment among people ≥65 y of age in China. Our sample is 72 821 adults aged 65–105 y from the seven waves of the Chinese Longitudinal Healthy Longevity Survey, a national mixed longitudinal cohort. The Chinese version of the Mini-Mental State Examination was used to measure CI. Risk factor-adjusted prevalence trend was examined using multilevel regression models. Age-standardized prevalence of cognitive impairment increased from 11.00% in 1998 to 11.84% in 2008 and decreased to 8.88% in 2014. Older age, female gender, less education, rural residence, not married, lack of physical and cognitive activities, suffering from stroke, vision and hearing impairment, and activities of daily living disability were negatively associated with cognitive impairment. Our study suggests a decreasing trend of cognitive impairment prevalence in China. However, whether decreasing prevalence will contribute to a reduced burden of cognitive impairment given the ageing of the population is unknown.

Objective We undertook a meta-analysis to investigate the effect of dexmedetomidine on postoperative cognitive dysfunction (POCD). Methods We searched PubMed, EMBASE, the Cochrane Library, CNKI and Google Scholar to find randomized controlled trials (RCTs) of the influence of dexmedetomidine on POCD in elderly adults who had undergone general anaesthesia. Two researchers independently screened the literature, extracted data, and evaluated methodologic quality against inclusion and exclusion criteria. We used RevMan 5.2 to undertake our meta-analysis. Results Thirteen RCTs were included. Compared with controls, dexmedetomidine: 1) significantly reduced the incidence of POCD (relative risk = 0.59, 95% confidence interval [CI] 0.45–2.95) and improved Mini-Mental State Examination (MMSE) score (mean difference, MD = 1.74, 95% CI 0.43–3.05) on the first postoperative day; and 2) reduced the incidence of POCD after the first postoperative day (MD = 2.73, 95% CI 1.33–4.12). Conclusion Dexmedetomidine reduces the incidence of POCD and improves postoperative MMSE score.

Objective To investigate the adequacy of the neuropsychological test battery proposed by the International Study of Postoperative Cognitive Dysfunction to evaluate this disorder in Brazilian elderly patients undergoing surgery under general anesthesia. Methods A neuropsychological assessment was made in patients undergoing non-cardiac surgery under general anesthesia, aged over 65 years, literate, with no history of psychiatric or neurological problems and score on the Mini Mental State Examination at or above the cutoff point for the Brazilian population (>18 or >23) according to the schooling level of the subject. Eighty patients were evaluated by a trained team of neuropsychologists up to 24 hours before elective surgery. Results Among the patients evaluated, one was excluded due to score below the cutoff point in the Mini Mental State Examination and two did not complete the test battery, thus remaining 77 patients in the study. The mean age was 69±7.5 years, and 62.34% of the subjects had ±4 years of study. The subjects had significantly lower averages than expected (p<0.001) for normative tables on neuropsychological tests. Conclusion The study demonstrated the applicability of the instruments in the Brazilian elderly and low schooling level population, but suggested the need to determine cutoff points appropriate for these individuals, ensuring the correct interpretation of results. This battery is relevant to postoperative follow-up evaluations, favoring the diagnosis of postoperative cognitive dysfunction in patients undergoing different types of surgery and anesthetic techniques.

Aims: To explore the impact of hospitalization on neuropsychiatric symptoms (NPS) and the level of functioning in patients with dementia. Our aim was also to study the influence of psychotropic medications. Methods: Behavioral disturbances, cognition and functional status of 89 patients were assessed using the Neuropsychiatric Inventory (NPI), Mini-Mental State Examination, Barthel Index, and Alzheimer's Disease Cooperative Study-Activities of Daily Living (ADCSADL). Results: The total NPI score decreased from 34.6 to 19.5 (p < 0.001), and ADL decreased from 32.2 to 21.7 (p < 0.001) during the hospital stay (mean of 44 days). For a change in ADL, only the effect of anxiolytics was significant (p = 0.045). For a change in NPI with antipsychotic and anxiolytic doses and Mini-Mental State Examination as covariates, no significant relationship was found. Conclusion: NPS improved significantly during hospitalization, but neither antipsychotic nor anxiolytic medication use explained this improvement. In patients using anxiolytics, the functional decline was substantial. These results do not support anxiolytic use in demented patients with NPS.
