Objective: This study aimed to investigate the effects of moderate to high-intensity aerobic exercise on HbA1c (Glycated hemoglobin), FBS (fasting blood sugar) and cognitive function in mild cognitive impairment prediabetes patients. Materials and Methods: Seventeen elderly mild cognitive impairment (age 55-70) men and women were selected and were randomly divided into 2 groups as aerobic (n=10) and control (n=10). Six subjects were excluded during the study. Finally, 14 subjects were continued the exercise program. Assessments were done at baseline and 12 weeks after intervention. The 12-weeks aerobic exercise program consisted of 90 min sessions in length 3 days per week under the supervision of the exercise specialist. Cognitive function, HbA1c, and FBS were evaluated. The differences in all variables (one way ANOVA), correlation (Pearson single correlation) and relative changes between baseline and 12 weeks (paired T-tests) were investigated. Results: HbA1c, FBS decreased significantly in the aerobic group whereas cognitive function increased significantly after 12 weeks aerobic ( P -value< 0.05 for all). Also, the change of cognitive function was significantly associated with a change of FBS (r= -0.84) after a 12-week aerobic exercise ( P -value: 0.011). Differences between groups in HbA1c, FBS and cognitive function (Mini-Mental State Examination) were not significant. Conclusion: Aerobic exercise may improve HbA1c, FBS and subsequently cognitive function in prediabetes elderly subjects. Therefore, a decrease in glycemic indicators could lead to improve cognitive function.

State Examination

In the elderly population, at least 10% of those over 65 years old and 50% of those over 80 years old experience a decline in cognitive function that varies from a cognitive decline due to normal aging (age-associated memory impairment/AAMI) to a mild cognitive decline (mild cognitive impairment/MCI) and dementia. Dementia is an intellectual disorder that affects the cognitive function, memory, language function, and visuospatial function that causes irreversible changes. Many studies have stated that lifestyle management in the form of increased physical activity has a protective effect on impaired cognitive functions, inhibits cognitive function decline, and even improves cognitive function in healthy elderly people and elderly with mild cognitive impairment to dementia. Low impact aerobic exercise is a physical activity that is useful and suitable for the elderly. This study aimed to determine the effect of low impact aerobic exercise on the cognitive function of elderly people with dementia. This was a quasi-experimental study with one group pretest-posttest method that involved elderly people from Tresna Werdha Teratai Palembang, South Sumatera, Indonesia who were selected based on the inclusion and exclusion criteria (n=38) from December 2018 to February 2019. Treatment provided was a low impact aerobic exercise 3 times a week for 5 weeks. Dementia was then measured before and after treatment using the Mini-mental State Examination (MMSE). The mean values of gymnastics before the treatment and after the treatment were 18.36±4.559 and 19.69±5.724, respectively. A p value of 0.000 was obtained using the Wilcoxon test. In summary, low impact aerobic exercise influences the cognitive function of the elderly with dementia. PENGARUH SENAM AEROBIK LOW IMPACT TERHADAP FUNGSI KOGNITIF USILA DENGAN DEMENSIAPada usia lanjut (usila), sedikitnya 10% dari yang berusia lebih dari 65 tahun dan 50% dari yang berusia lebih dari 80 tahun mengalami penurunan fungsi kognitif yang bervariasi mulai dari penurunan kognitif karena penuaan normal (age-associate memory impairment/AAMI) serta penurunan kognitif ringan (mild cognitive impairment/MCI) hingga demensia. Demensia adalah gangguan intelektual yang meliputi fungsi kognitif, daya ingat, bahasa, fungsi visuospasial, dan bersifat ireversibel. Banyak studi menyatakan bahwa manajemen gaya hidup berupa peningkatan aktivitas fisik mempunyai efek protektif terhadap gangguan fungsi kognitif, menghambat penurunan fungsi kognitif, serta bahkan meningkatkan fungsi kognitif pada usila yang sehat dan usila dengan penurunan fungsi kognitif ringan sampai demensia. Senam aerobik low impact merupakan aktifitas fisik yang bermanfaat dan cocok diberikan kepada usila. Penelitian ini bertujuan mengetahui pengaruh senam aerobik low impact terhadap fungsi kognitif usila dengan demensia. Penelitian ini merupakan studi quasi-experimental dengan metode pretest-posttest one group yang melibatkan usila dari Tresna Werdha Teratai Palembang, Sumatera Selatan, Indonesia yang dipilih berdasar atas kriteria inklusi dan eksklusi (n=38) dari bulan Desember 2018 hingga Februari 2019. Perlakuan yang diberikan berupa senam aerobik low impact 3 kali per minggu selama 5 minggu. Demensia kemudian diukur sebelum dan sesudah perlakuan menggunakan Mini-mental State Examination (MMSE). Nilai rerata senam sebelum perlakuan dan setelah perlakuan adalah 18,36±4,559 dan 19,69±5,724 masing-masing. Nilai p=0,000 didapatkan dengan menggunakan Uji Wilcoxon. Simpulan, senam aerobik low impact memengaruhi fungsi kognitif usila dengan demensia.

Addenbrooke’S Cognitive Examination

Background/Aims: The diagnostic accuracy of the Cuban version of the revised Addenbrooke’s Cognitive Examination (ACE-R) in identifying mild cognitive impairment (MCI) in comparison with the Mini-Mental State Examination (MMSE) was assessed. Methods: The Cuban ACE-R was administered to a group of 129 elderly subjects (92 cognitively healthy and 37 subjects with MCI). The t tests for independent samples were used to compare scores of different psychometric scales between groups, and effect sizes (Cohen’s d) were calculated. Cronbach’s coefficient α was used to evaluate the reliability of psychometric scales. The validity of ACE-R to screen for MCI was assessed by receiver operating characteristic (ROC) curves. Results: The Cuban ACE-R had reliable internal consistency (Cronbach’s coefficient α = 0. 879). The optimal cut-off score for ACE-R for detecting MCI was 84/85. The sensitivity and specificity of ACE-R to screen for MCI was superior to those of MMSE. The area under the ROC curve of the Cuban ACE-R was much larger than that of MMSE (0.93 and 0.63) for detecting MCI. Conclusion: The Cuban ACE-R is a valid screening tool for detecting cognitive impairment. It is more sensitive and accurate in screening for MCI than MMSE.

Intermittent Fasting

Intermittent fasting (IF) refers to various dietary regimens that cycle between a period of non-fasting and a period of total fasting. This study aimed to determine the effects of IF on cognitive function among elderly individuals who practice IF who have mild cognitive impairment (MCI). A total of 99 elderly subjects with MCI of Malay ethnicity without any terminal illness were recruited from a larger cohort study, LRGS TUA. The subjects were divided into three groups, comprising those who were regularly practicing IF (r-IF), irregularly practicing IF (i-IF), and non-fasters (n-IF). Upon 36 months of follow-up, more MCI subjects in the r-IF group reverted to successful aging with no cognitive impairment and diseases (24.3%) compared to those in i-IF (14.2%) and n-IF groups (3.7%). The r-IF group’s subjects exhibited significant increment in superoxide dismutase (SOD) activity and reduction in body weight, levels of insulin, fasting blood glucose, malondialdehyde (MDA), C-reactive protein (CRP), and DNA damage. Moreover, metabolomics analysis showed that IF may modulate cognitive function via various metabolite pathways, including the synthesis and degradation of ketone bodies, butanoate metabolism, pyruvate metabolism, and glycolysis and gluconeogenesis pathways. Overall, the MCI-afflicted older adults who practiced IF regularly had better cognitive scores and reverted to better cognitive function at 36 months follow-up.

OBJECTIVE: To determine the diagnostic accuracy of the Mini-Mental State Examination combined to the Informant Questionnaire on Cognitive Decline in the Elderly for the identification of mild cognitive impairment. METHOD: 191 elderly subjects were assessed with the Mini-Mental State Examination, and their informants were assessed with the Informant Questionnaire on Cognitive Decline in the Elderly. Subjects were divided into three groups according to their cognitive state (controls: n = 67, mild cognitive impairment: n = 65 and dementia: n = 59), which was ascertained by clinical and neuropsychological evaluation. The diagnostic accuracy of each test in the discrimination of diagnostic groups (mild cognitive impairment vs. controls, mild cognitive impairment vs. dementia and dementia vs. controls) was examined with the aid of ROC curves. We additionally verified if the combination of both tests would increase diagnostic accuracy for mild cognitive impairment and control identification. RESULTS: The combination of the Mini-Mental State Examination and the Informant Questionnaire on Cognitive Decline in the Elderly scores did not increase the Mini-Mental State Examination diagnostic accuracy in the identification of patients with mild cognitive impairment. CONCLUSIONS: The present data do not warrant the combination of the Mini-Mental State Examination and the Informant Questionnaire on Cognitive Decline in the Elderly as a sufficient diagnostic tool in the diagnostic screening for mild cognitive impairment.

Introduction: Recent studies have shown that Polyunsaturated Fatty Acids (PUFAs), including Eicosapentaenoic Acid (EPA), and Arachidonic Acid (AA), are associated with cognitive functions in patients with Coronary Artery Disease (CAD). Nevertheless, controversial results have been reported, too. The current study aimed to clarify the association of serum EPA and AA levels with cognitive decline in an Iranian sample with CAD. Methods: We evaluated cognitive function with the Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA), in relation to serum levels of EPA and AA, in 179 CAD patients. The associations between the MMSE and MoCA scores and the other demographic parameters were evaluated. Results: Patients with CAD generally had mild cognitive impairment. But we could not find any significant correlation between PUFAs and cognitive function. However, BMI was associated with EPA/MoCA; age was associated with MMSE/MoCA and BMI. Finally, the correlation between sex and MMSE/MoCA was significant. Conclusion: Subjects generally had mild cognitive impairment, but we could not find any significant correlation between serum EPA and AA levels with cognitive function.

BackgroundHigher docosahexaenoic acid (DHA) intake is inversely correlated with relative risk of Alzheimer’s disease. The potential benefits of DHA supplementation in people with mild cognitive impairment (MCI) have not been fully examined.ObjectiveOur study aimed to assess the effect of a 24-month DHA supplementation on cognitive function and amyloid beta (Aβ)-mediated autophagy in elderly subjects with MCI.MethodsThis was a randomised, double-blind, placebo-controlled trial in Tianjin, China. A total of 240 individuals with MCI were identified and randomly divided into intervention (DHA 2 g/day, n=120) and control (corn oil as placebo, n=120) groups. Cognitive function and blood Aβ-related biomarkers were measured at baseline, 6, 12, 18 and 24 months. Data were analysed using generalised estimating equation.ResultsA total of 217 participants (DHA: 109, placebo: 108) completed the trial. During the follow-up, scores of full-scale IQ, verbal IQ and subdomains of information and digit span were significantly higher in the intervention group than the convention group (p<0.05). In the intervention group, blood Aβ-42 level and expression of Aβ protein precursor mRNA were decreased (p<0.05), while Beclin-1 and LC3-II levels and expression of LC3-II mRNA were increased (p<0.05).ConclusionDaily oral DHA supplementation (2 g/day) for 24 months may improve cognitive function and change blood biomarker-related Aβ-mediated autophagy in people with MCI. Larger longer-term confirmatory studies are warranted.Trial registration numberChiCTR-IOR-15006058.
