The effect of different language backgrounds on performance and the functional equivalence of trail making tests were examined. The children's version of the Trail Making Test A and B (TMT) and the Children's Color Trails Test 1 and 2 (CCTT) were employed with right-handed (n = 79) participants. Children were classified into three groups according to language proficiency: Chinese dominant (CDL), Chinese-English bilinguals (CEB), and English dominant (EDL). In general, the CDL group exhibited the best performance on Children's Color Trails 1 and 2 and Trail Making Test A and B. In examining the functional equivalence of TMT and CCTT, both tests were influenced by language background and intelligence but not gender. The results suggest that language backgrounds do exert a modest effect on trail making tests and that diverging executive demands on CCTT 2 versus TMT B may impact their functional equivalence with different groups of participants. Therefore, caution should be exercised when comparing or replacing CCTT with TMT in children from different and diverging language backgrounds.

Apolipoprotein () genotype and nitric oxide (NO) deficiency are risk factors for age-associated cognitive decline. The oral microbiome plays a critical role in maintaining NO bioavailability during aging. The aim of this study was to assess interactions between the oral microbiome, NO biomarkers, and cognitive function in 60 participants with mild cognitive impairment (MCI) and 60 healthy controls using weighted gene co-occurrence network analysis and to compare the oral microbiomes between carriers and noncarriers in a subgroup of 35 MCI participants.

Prcis: Cognitive impairment in multiple domains was observed in primary open angle glaucoma patients as compared to age and gender matched healthy controls.
Objective: Evaluation of cognitive impairment in individuals with Primary Open Angle Glaucoma (POAG).
Methods: In this case-control study, individuals with POAG (cases, n=70) were compared with age- and sex-matched healthy individuals (controls, n=70) using detailed ophthalmological evaluation, cognitive assessment and serum cortisol level.

Objective: Obsessive compulsive disorder (OCD) and anorexia nervosa (AN) are conditions associated with poor cognitive flexibility, a factor considered to interfere with treatment, but research into the relationship between cognitive flexibility and treatment outcome is limited. This study explores whether baseline measures of cognitive flexibility predict outcomes in OCD and AN, evaluates whether changes in these measures contribute to treatment outcome, and evaluates the effectiveness of adjunctive cognitive remediation therapy (CRT) in improving cognitive flexibility.
Methods: This secondary analysis utilized linear mixed model analysis on data from a randomized controlled multicenter clinical trial involving adult participants with OCD (n=71) AND AN (n=61).

Objectives: This study analyzed the effects of parachute jump stress on the executive functions and attention of cadets. Executive functions, which includes processes such as attentional control and cognitive flexibility, are crucial for soldiers, especially in situations requiring rapid decision-making. Parachute jumping, as an intense stressor, mobilizes cognitive resources, which can lead to short-term improvements in executive functions.

Our previous study revealed the benefits of chronic melatonin intake on dynamic postural imbalance and poor walking capacity induced by multiple sclerosis but its impact on muscle weakness and poor manual dexterity related to this disease has not yet been explored. The objective of the current study was to investigate the effectiveness of 12-week melatonin supplementation on motor skills (i.e.
