Introduction: The aging process is characterized by morphological, physiological, biochemical and psychological changes that depend on the lifestyle. This process is the result of the accumulation of molecular and cellular damage throughout life, leading to a gradual decrease in physical and mental capacity, and greater chances of the development of pathologies such as the decline in cognitive function. Studies show that adequate consumption of foods containing selenium (Se) acts to inhibit the production of free radicals, reducing the damage caused by oxidative stress. Therefore, the aim of this study was to investigate the relationship between selenium consumption and the maintenance of cognitive function. Methods:A systematic review of scientific articles was carried out to analyze the relationship between Se consumption and cognitive function in the elderly. The identification of the articles was carried out in the electronic databases Pubmed, MEDLINE and LILACS, by two independent researchers. In all databases, the search was performed using the Results: The search resulted in 270 studies, however, applying the inclusion and exclusion criteria, eight articles were selected. Conclusion: We conclude that an adequate intake of Se must be indicated in order to maintain the brain function. In summary, the articles discussed in the presente study show a high relation of Se consumption and the improvement of cognitive performance, both in humans and in animals.

There is currently a great interest to combine electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) to study brain function. Earlier studies have shown different EEG components to correlate well with the fMRI signal arguing for a complex relationship between both measurements. In this study, using separate EEG and fMRI measurements, we show that (1) 0.1 ms visual stimulation evokes detectable hemodynamic and visual-evoked potential (VEP) responses, (2) the negative VEP deflection at ∼80 ms (N2) co-varies with stimulus duration/intensity such as with blood oxygenation level-dependent (BOLD) response; the positive deflection at ∼120 ms (P2) does not, and (3) although the N2 VEP–BOLD relationship is approximately linear, deviation is evident at the limit of zero N2 VEP. The latter finding argues that, although EEG and fMRI measurements can co-vary, they reflect partially independent processes in the brain tissue. Finally, it is shown that the stimulus-induced impulse response function (IRF) at 0.1 ms and the intrinsic IRF during rest have different temporal dynamics, possibly due to predominance of neuromodulation during rest as compared with neurotransmission during stimulation. These results extend earlier findings regarding VEP–BOLD coupling and highlight the component- and context-dependency of the relationship between evoked potentials and hemodynamic responses.

Article focuses on the use of 99mTc-HMPAO brain SPECT for evaluation of cerebral blood flow in patients with arterial hypertension and identification of the relationship of brain perfusion and cognitive function. Using SPECT of brain with 99mTc-HMPAO it was found out that hypertensive patients even in the absence of focal neurological symptoms have hypoperfusion of the brain which leads to cognitive dysfunction: decreased attention, psychomotor speed and slow thought processes.

Introduction: Physical frailty (PF) appears to be associated with low cognitive performance and mild cognitive impairment (MCI). This review evaluated and synthesized the evidence of studies investigating the association between PF and MCI, the prevalence of both conditions and the rate of conversion of healthy older adult to one of them during the follow-up. Methods: A systematic review was performed according to the PRISMA recommendations in the Pubmed, SciELO and LILACS databases. Five studies were eligible according to inclusion and exclusion criteria. Results: Regarding the study design, cross-sectional studies prevailed. Most studies showed a positive association between PF and MCI. Moreover, PF seems to predict a worse cognitive trajectory among participants with MCI and it is associated to a higher risk of developing MCI. Conclusion: Our findings suggest a significant association between PF and MCI. Further longitudinal studies are needed to better explore causality.

ABSTRACT Physical activity is a factor that can inhibit cognitive decrease in the elderly. One of the preventive actions that can be done by the elderly in slowing down the decrease of cognitive function is to increase physical activity. Physical activity is thought to stimulate nerve growth which might inhibit cognitive decrease in the elderly. When doing physical activity, the brain will be stimulated so that it will increase the Brain Derived Neurotropic Factor which plays a role in keeping nerve cells fit and healthy. Based on the explanation, the aim of this study was to identify the relationship between physical activity and cognitive function in the elderly. This study was a quantitative study with a categorical correlative analytic method. The study used cross sectional study design. The chi-square test and ordinal logistic regression test were used for data analysis. The results of this study stated that the overall physical activities which were exercise, mild activity, heavy activity, use of stairs and participate in social activities showed a significant relationship to cognitive function. Participating in social activities and mild activity were the most significant physical activities that showed relationship to cognitive function, with p-value = 0.001 < 0.05. In conclusion, the findings highlight that the choice of appropriate physical activity can help to maintain cognitive function in the elderly.

AbstractBoth the brain and microbiome of humans develop rapidly in the first years of life, enabling extensive signaling between the gut and central nervous system (dubbed the “microbiome-gut-brain axis”). Emerging evidence implicates gut microorganisms and microbiota composition in cognitive outcomes and neurodevelopmental disorders (e.g., autism), but the influence of gut microbial metabolism on typical neurodevelopment has not been explored in detail. We investigated the relationship of the microbiome with the neuroanatomy and cognitive function of 281 healthy children in a cross-sectional analysis and demonstrated that differences in gut microbial taxa and gene functions are associated with the size of brain regions and with overall cognitive function. Many species, including Eubacterium eligens and Roseburia hominis, were associated with higher cognitive function, while some species such as Ruminococcus gnavus was more commonly found in children with low cognitive scores. Microbial enzymes involved in the metabolism of neuroactive compounds such as glutamate and GABA, were also associated with structure of the brain, including the first brain regions to develop such as the cerebellum, and with overall cognitive function.

The relationship of addiction problems with other pathologies or with different problematic factors has often been studied by psychology. Positive psychology is also currently approaching to these problems and their relationship with positive factors, such as prosocial behaviours. The purpose of this research is to carry out a systematic review of the scientific literature that has studied this relationship from 1900 to 2020. After the screening process with the inclusion and exclusion criteria, a total of 15 articles were selected. The main characteristics found in this relationship and the problems or limitations of investigations that have found relationships other than the mainstream, which show a negative relationship between prosocial behaviours and addiction problems, are discussed.
