“…The participants’ executive function was evaluated by using Trail Making Test B (TMB; corrected; Reitan, 1955) and Stroop interference test (Amieva et al., 2004). As the calculation ability depends on executive function (Jogi and Kikas, 2016), calculation ability was evaluated to reflect part of executive function. Our calculation tests comprised two additions, two subtractions, and one multiplication.…”

Physical exercise has been associated with enhanced memory formation and consolidation in patients with mild cognitive impairment (MCI). This study aimed to investigate the relationship between objective neuropsychological performances and continuously recorded physical activity. A cutoff value of measured physical activity was used to differentiate early-stage and late-stage MCI. Fifty-four patients with MCI were included. The relationship between cognitive function and measures of daily activity measured by continuous three-axis accelerometers in Xiaomi Mi Band, including subject-level average step counts, average distance (kilometers), and average calorie expenditure per day of 7-day activity, was determined. The slope of the receiver operating characteristic curve was used to determine the measures of activity to draw comparisons between early-stage MCI and late-stage MCI. The patients were assessed by using several cognitive tests such as Cognitive Abilities Screening Instrument and Chinese Version Verbal Learning Test. The multivariate linear regression model indicated a significant correlation of higher average step counts per day of 7-day activity (aver-step-counts) with higher score in visual construction (b ¼ 0.355; p ¼ .015). To differentiate patients with late-stage MCI from those with early-stage MCI, the cutoff value of 6,284 steps on aver-step-counts showed an optimal sensitivity and specificity (Youden index ¼ 0.36, area under the curve ¼ 0.651, p ¼ .042). The aver-step-counts showed a significantly better differentiating rate between patients with early-stage and late-stage MCI than average calorie expenditure per day of 7-day activity did (p ¼ .046). Accelerometerdetermined measures of activity patterns show as potential measurement to reflect cognitive function.

“…Calculation processing has been associated with increased functional activity in the prefrontal cortex, suggesting the role of ECN in the calculation ability (Menon et al, 2000). Although the calculation ability depends on previous math skills, linguistic abilities, and executive function (Jogi and Kikas, 2016), the calculation score might be associated with executive performances after controlling for educational level of each patient. Moreover, evaluating the calculation performance might play an important role in AD because it has been suggested as a tool for cognitive rehabilitation in dementia patients (Kawashima et al, 2005).…”

Purpose of the researchAlthough single nucleotide polymorphisms of membrane-spanning 4A (MS4A) (rs670139) and several other susceptibility genes have shown interaction effects on the risk of Alzheimer's disease (AD), little is known about the interaction effects of apolipoprotein E (APOE) with MS4A (rs670139) on cognitive performances, and the underlying pathogenesis is unclear. The study aimed to investigate the APOE-MS4A (rs670139) interaction effects on cognitive performances, cortical volumes, and functional connectivity (FC) in brain networks.Principal resultsCognitive performances were characterized in each genotypic group, and were compared between normal controls and patients in each genotypic group. APOE-MS4A interaction effects on memory and executive function scores, cortical volumes, and FC in brain networks were demonstrated. Significant effects of APOE-MS4A interactions on FC were observed in executive control network (ECN) (T maxima = 4.99, false discovery rate-corrected p < .001), the calculation score (F3, 87 = 6.218; p = .015), and the volume in prefrontal (F3, 87 = 4.374; p = .039) and orbitofrontal cortices (F3, 87 = 6.022; p = .016). The calculation score was correlated with each frontal volume (cc) (ρ = 0.304; p = .004) and genetic interaction-associated FC in ECN (ρ = 0.282; p = .008). Variations in genotypes affected the relationship between the calculation score and each frontal volume (cc).Major conclusionsThese findings indicate that the genetic interaction effects on FC in ECN might contribute to pathogenic mechanisms underlying the interaction effects of APOE-MS4A on calculation ability in AD.

“…(1) Our first argument is based on the definition of CPS and the characteristic features of complex problems typically used in research: There is a problem whenever an organism wants to reach a goal but does not know how to do so (Duncker and Lees, 1945 ); and a problem is complex if a large number of highly interrelated aspects have to be considered in parallel (Dörner, 1997 ; Fischer et al, 2012 ). Problem solving is the activity of searching for a solution.…”
