Abstract Objectives: Meta-tasking (MT) is an aspect of executive functioning (EF) that involves the ability to branch (i.e., to apply “if-then” rules) and to effectively interleave sub-goals of one task with sub-goals of another task. As such, MT is crucial for successful planning, coordination, and execution of multiple complex tasks in daily life. Traditional tests of EF fail to adequately measure MT. This study examined whether Condition 4 of the Color-Word Interference Test (CWIT-4; the inhibition/switching condition that requires branching) predicted MT beyond Condition 3 (CWIT-3; inhibition-only condition) and beyond other subtests from the Delis–Kaplan Executive Function System (D-KEFS) that have a switching condition. Method: Ninety-eight non-Hispanic white community-dwelling older adults completed the first four subtests of the D-KEFS and an ecologically valid measure of MT. Results: Time to completion and total errors on CWIT-4 accounted for variance in MT above and beyond CWIT-3 and beyond the switching conditions of other D-KEFS subtests. Results remained virtually unchanged when controlling for demographics and general cognitive status. Conclusions: Among older adults, CWIT-4 is more strongly associated with MT than other D-KFES tasks. Future research should examine whether CWIT-4 relates to lapses in instrumental activities of daily living among older adults above and beyond other EF tests.

AbstractIn the absence of any neuropsychiatric condition, older adults may show declining performance in several cognitive processes and among them, in retrieving and producing words, reflected in slower responses and even reduced accuracy compared to younger adults. To overcome this difficulty, healthy older adults implement compensatory strategies, which are the focus of this paper. We provide a review of mainstream findings on deficient mechanisms and possible neurocognitive strategies used by older adults to overcome the deleterious effects of age on lexical production. Moreover, we present findings on genetic and lifestyle factors that might either be protective or risk factors of cognitive impairment in advanced age. We propose that “aging-modulating factors” (AMF) can be modified, offering prevention opportunities against aging effects. Based on our review and this proposition, we introduce an integrative neurocognitive model of mechanisms and compensatory strategies for lexical production in older adults (entitled Lexical Access and Retrieval in Aging, LARA). The main hypothesis defended in LARA is that cognitive aging evolves heterogeneously and involves complementary domain-general and domain-specific mechanisms, with substantial inter-individual variability, reflected at behavioral, cognitive, and brain levels. Furthermore, we argue that the ability to compensate for the effect of cognitive aging depends on the amount of reserve specific to each individual which is, in turn, modulated by the AMF. Our conclusion is that a variety of mechanisms and compensatory strategies coexist in the same individual to oppose the effect of age. The role of reserve is pivotal for a successful coping with age-related changes and future research should continue to explore the modulating role of AMF.

Abstract Objective Metabolic syndrome (MetS) is associated with increased rates of mortality and increased risk for developing dementia. Changes in brain structure and executive functioning have been reported within the literature. However, research examining cognitive performance in individuals with metabolic syndrome focuses primarily on older cohorts. As such, the effect of metabolic syndrome on cognitive functioning earlier in the lifespan is unclear. This research examined neuropsychological test performance and self-report measures in young, middle-aged, and older adults with and without MetS. Method Participants (n = 128) were categorized by age and metabolic status as follows: Young: n = 42, 52.4% Metabolic; Middle-Age: n = 41, 56.1% Metabolic; Older: n = 45, 51.1% Metabolic. Participants were administered the following cognitive assessments as part of a larger study: Delis-Kaplan Executive Function System (DKEFS) Color-Word Interference Test and Trail Making. Multivariate analyses of variance were used to examine the relationship between age group, metabolic status, and cognitive performance. Results As expected, older adults performed more poorly than young and middle-aged adults across neurocognitive assessments (p < .05). MetS adults performed more slowly on Color-Word Interference: Inhibition [F(1,114) = 5.26, p = .024, η2 = .05]; however, there were no additional significant differences between groups on cognitive tests in this sample size. Conclusions These findings suggest that aspects of inhibition might be impaired in MetS adults. Future studies aimed at investigating relationships between metabolic risk factors and inhibition may provide insight into effective intervention targets to delay or prevent metabolic syndrome.

Social Loneliness

The present longitudinal study aims to explain emotional and social loneliness experienced by older adults ( N=99) during two-and-a-half years of widowhood. Utilization of multilevel analysis and a “visual” cluster analysis with prescribed classification criteria enabled us to search for average adaptational developments as well as individual variability in the adjustment process. Results were interpreted within the theory of mental incongruity. Adjustment to loneliness appears to develop along different individual-specific curves. About 30 percent of the bereaved had not adapted in two-and-a-half years to their loss in terms of emotional loneliness. Presence of favorable opportunities such as good health and high self-esteem as well as coping efforts like social behavior resulted in lower levels of emotional and social loneliness. It is concluded that the adjustment process among older bereaved does not exist. Moreover, including measures of cognitions and attitudes that are related to the relational needs and desires of widow(er)s may enlarge our knowledge of how older adults adapt to partner death.

Speech Identification

Purpose This study examined the relationship between working memory (WM) and speech comprehension in older adults with hearing impairment (HI). It was hypothesized that WM would explain significant variance in speech comprehension measured in multitalker babble (MTB). Method Twenty-four older (59–73 years) adults with sensorineural HI participated. WM capacity (WMC) was measured using 3 complex span tasks. Speech comprehension was assessed using multiple passages, and speech identification ability was measured using recall of sentence final-word and key words. Speech measures were performed in quiet and in the presence of MTB at + 5 dB signal-to-noise ratio. Results Results suggested that participants' speech identification was poorer in MTB, but their ability to comprehend discourse in MTB was at least as good as in quiet. WMC did not explain significant variance in speech comprehension before and after controlling for age and audibility. However, WMC explained significant variance in low-context sentence key words identification in MTB. Conclusions These results suggest that WMC plays an important role in identifying low-context sentences in MTB, but not when comprehending semantically rich discourse passages. In general, data did not support individual variability in WMC as a factor that predicts speech comprehension ability in older adults with HI.

Resistant Depression

IntroductionTreatment resistant depression (TRD) is a disabling condition associated with a relevant psychosocial impairment worldwide.ObjectivesThis exploratory study is aimed to evaluate the main clinical and neurocognitive characteristics in a sample of 21 subjects admitted to the Psychiatric Clinic of University of Genoa as inpatients between 2015 and 2016 and diagnosed with TRD according to Thase and Rush staging method.MethodsPatients have been assessed using the Hamilton Depression Rating Scale (HDRS), Hamilton Anxiety Rating Scale, and Clinical Global Impression (CGI). The Continuous Performance Test (CPT), Trial Making Test (TMT-A/B), Stroop Color Word Interference Test, Verbal Fluency Test, and Rey auditory-verbal learning test (RAVLT) have been administered as well.ResultsSubjects with early-onset (< 50 years) depression had a longer illness duration, higher depressive episodes and more impaired performance at RAVLT while individuals with late-onset (> 50 years) depression showed a higher severity of depressive symptoms and more anxiety symptoms. Depressive symptoms were positively associated with anxiety (r = 0.82; P = 0.00) and negatively with TMT-A/B (r = −0.56, P = 0.01), Stroop Color Word Interference Test (r = −0.72, P = 0.005 and r = −0.616, P = 0.008), and RAVLT (r = −0.60; P = 0.02) performances. According to regression analyses, anxiety symptoms were the only significant predictor of depression severity (P = 0.02).ConclusionsEarly-onset depression is associated with more disability and worse neurocognitive performance whereas late-onset depression is linked to more anxiety symptoms and more depressive symptoms severity. Clinicians should closely monitor patients with TRD for the presence of anxiety symptoms that may represent a significant risk factor of poorer long-term outcome.Disclosure of interestThe authors have not supplied their declaration of competing interest.
