Abstract Objectives An intervention study was performed to determine if supplement containing blueberry extracts could improve cognitive function in the elderly patients with mild cognitive impairment (MCI). Methods Forty six MCI patients participated in the intervention study were paired based on their age, education level and initial the basic cognitive aptitude test (BCAT) scores and then randomly assigned to the intervention group (n = 23, which received 1.0 g/day of blueberry extracts) or blank control group (n = 23) . The endpoint was the improvement in cognitive function as evaluated by BCATs. All parameters were measured before and after the treatment period of 12 weeks. Results After 12 weeks of intervention, we observed significant improvement in their total BCAT score, space imagery efficiency, working memory and recognition memory of subjects in patients with blueberry extracts supplementation comparing to those in the control group (P = 0.006, 0.023, 0.000, 0.005, respectively). However the levels of inflammatory factors (IL-6 and TNF-α in serum) showed no significant changes after intervention. Conclusions The data indicated that blueberry has a beneficial effect on cognitive function of the elderly MCI patients, which might provide therapeutic potential for Alzheimer's disease.

Purpose: With the benefits of advanced medical technology, Taiwan has gradually changed from an aged society to a super-aged society. According to previous studies, the prevalence rate of mild cognitive impairment (MCI) over the age of 60 is 15% to 20%. Therefore, the main purpose of our study was to analyze the correlation of cognitive function with visual function (specifically, binocular vision and visual perception) in Taiwanese volunteers aged 60 years or older. Methods: Thirty-six healthy participants who were not taking psychiatric medications and who had not been diagnosed with any retinal or optic nerve diseases were enrolled. Addenbrooke’s cognitive examination III (ACE-III), binocular visual function, and visual perception evaluation were performed, and the data analyzed statistically by t-test, χ2, linear regression, and MANOVA. Results: Cognitive function was closely correlated with visual function and visual perception; the horizontal adjustment time of binocular eye movement, stereopsis, the motor-free visual perception test-4 (MVPT-4), and peripheral awareness actually displayed higher explanatory power in predicting cognitive function. In addition, various interactive parameters between visual function and visual perception were found to affect specific aspects of ACE-III. Discussion: Our study revealed that there was a close correlation of cognitive function with visual function; as such, it may be possible to predict visual function deficits in patients with mild cognitive impairment.

Descriptive Method

Elderly is not a disease, but is an advanced stage of a life process characterized by a decrease in the body's ability to adapt to environmental stress. Elderly causes anatomical, physiological, and biochemical changes in the body, so that it will affect the overall function and ability of the body. The study aims to determine the picture of independence and cognitive function in the elderly. The study used a descriptive method with a sample of 108 elderly in the City of Kendal Indonesia. Data were analyzed using frequency distribution. The results showed the majority of respondents (81.5%) elderly were categorized as having the ability to independently level and 78.6% had normal cognitive function, 18.5% had mild cognitive impairment, and 1.9% had severe cognitive impairment.  Keywords: independence, cognitive function, elderly

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.
