The Impact

Deaf and hard of hearing (DHH) children have been claimed to lag behind their hearing peers in various domains of cognitive development, especially in implicit learning, executive function, and working memory. Two major accounts of these deficits have been proposed: one based on a lack of auditory access, and one based on a lack of language access. This chapter reviews these theories in relation to the available evidence and concludes that there is little evidence of direct effects of diminished auditory access on cognitive development that could not also be explained by diminished language access. Specifically, reports of deficits in implicit learning are not broadly replicable. Some differences in executive function do stem from deafness itself but are not necessarily deficits. Where clinically relevant deficits in executive function are observed, they are inconsistent with the predictions of accounts based on auditory access, but consistent with accounts based on language access. Deaf–hearing differences on verbal working memory tasks may indicate problems with perception and/or language, rather than with working memory. Deaf–hearing differences on nonverbal tasks are more consistent with accounts based on language access, but much more study is needed in this area. The chapter concludes by considering the implications of these findings for psychological theory and for clinical/educational practice and by identifying high-priority targets for future research.

The Relationship

Abstract Objective: Findings on the relationship of psychiatric symptoms with performance-based and self-reported cognitive function post-stroke are inconclusive. We aimed to (1) study the relation of depression and anxiety to performance-based cognitive function and (2) explore a broader spectrum of psychiatric symptoms and their association with performance-based versus self-reported cognitive function. Method: Individuals with supratentorial ischemic stroke performed neuropsychological examination 3 months after stroke. For primary analyses, composite scores for memory and attention/executive function were calculated based on selected neuropsychological tests, and the Hospital Anxiety and Depression Scale (HADS) was used. Psychiatric symptoms and self-reported cognitive function for secondary aims were assessed using the Symptom-Checklist-90 – Revised (SCL-90-R). Results: In a sample of 86 patients [mean (M) age: 64.6 ± 9.2; Mini-Mental State Examination (MMSE), 3–7 days post-stroke: M = 28.4 ± 1.7; National Institutes of Health Stroke Scale (NIHSS) after 3 months: M = 0.7 ± 1.6] depressive symptoms (HADS) were associated with poorer memory performance after controlling for age, sex, and education (p ≤ .01). In a subsample (n = 41; Age: M = 65.7 ± 8.1; MMSE: M = 28.4 ± 1.8; NIHSS: M = 1.0 ± 1.9), symptoms of phobic anxiety (SCL-90-R) were associated with poorer performance-based memory and attention/executive function, and symptoms of anxiety (SCL-90-R) with lower attention/executive function. Higher levels of self-reported cognitive difficulties were associated with higher scores in all psychiatric domains (p ≤ .05). Conclusion: Even in relatively well-functioning stroke patients, depressive symptoms are associated with poorer memory. The results also suggest that various psychiatric symptoms are more related to self-reported rather than to performance-based cognitive function. Screening for self-reported cognitive difficulties may not only help to identify patients with cognitive impairment, but also those who need psychological treatment.

Core Feature

BackgroundThis review aimed to address the question of whether cognitive impairment should be considered a core feature of depression that may be a valuable target for treatment.MethodWe conducted a systematic review and meta-analysis of cognitive function, assessed with a single neuropsychological test battery, the Cambridge Neuropsychological Test Automated Battery (CANTAB), in patients with depression during symptomatic and remitted states. Inclusion of studies comparing patients remitted from depression and controls enabled us to investigate whether cognitive impairment persists beyond episodes of low mood in depression.ResultsOur meta-analysis revealed significant moderate cognitive deficits in executive function, memory and attention in patients with depression relative to controls (Cohen's d effect sizes ranging from −0.34 to −0.65). Significant moderate deficits in executive function and attention (Cohen's d ranging from −0.52 to −0.61) and non-significant small/moderate deficits in memory (Cohen's d ranging from −0.22 to −0.54) were found to persist in patients whose depressive symptoms had remitted, indicating that cognitive impairment occurs separately from episodes of low mood in depression.ConclusionsBoth low mood and cognitive impairment are associated with poor psychosocial functioning. Therefore, we argue that remediation of cognitive impairment and alleviation of depressive symptoms each play an important role in improving outcome for patients with depression. In conclusion, this systematic review and meta-analysis demonstrates that cognitive impairment represents a core feature of depression that cannot be considered an epiphenomenon that is entirely secondary to symptoms of low mood and that may be a valuable target for future interventions.

Studies have shown thatAllium sativumL. (AS) protects amyloid-beta peptide-induced apoptosis, prevents oxidative insults to neurons and synapses, and thus prevent Alzheimer’s disease progression in experimental animals. However, there is no experimental evidence in human regarding its putative role in memory and cognition. We have studied the effect of AS consumption by healthy human volunteers on visual memory, verbal memory, attention, and executive function in comparison to control subjects taking placebo. The study was conducted over five weeks and twenty volunteers of both genders were recruited and divided randomly into two groups: A (AS) and B (placebo). Both groups participated in the 6 computerized neuropsychological tests of the Cambridge Neuropsychological Test Automated Battery (CANTAB) twice: at the beginning and after five weeks of the study. We found statistically significant difference (p<0.05) in several parameters of visual memory and attention due to AS ingestion. We also found statistically nonsignificant (p>0.05) beneficial effects on verbal memory and executive function within a short period of time among the volunteers. Study for a longer period of time with patients suffering from neurodegenerative diseases might yield more relevant results regarding the potential therapeutic role of AS.

Abstract Physical activity may preserve cognitive functioning in older adults. This study examined associations between objectively measured physical activity and cognitive functioning. We recruited participants (Mage = 75.38 years, SD = 5.99) with (N=26) and without (N=181) cognitive impairment from the University of Kansas Alzheimer’s Disease Center (KU-ADC). We collected cognitive data representing verbal memory, attention, and executive function. Accelerometers (Actigraph GT9X) were used to measure physical activity 24 hours a day for 7 days in a free-living environment. Physical activity was categorized as moderate to vigorous physical activity (MVPA) based on the Freedson (2011) Adult Vector Magnitude cut points. The association between cognitive functioning and total MVPA was evaluated by using multiple regression. We used factor analysis to create three composite scores (verbal memory, attention, executive function) from 11 individual cognitive tests. Compared to verbal memory and attention, results indicate that total MVPA was more strongly associated with executive function (β = 0.001, p = .024). These findings are consistent with the literature suggesting that executive function in older adults may benefit from physical activity. Future research should investigate the physiological mechanisms by which MVPA benefits executive function in contrast to types of activity that might benefit verbal memory and attention.

Abstract Objectives The majority of global health studies use behavioural assessments to measure early child development. Few studies have examined neural indices of cognition using electroencephalography (EEG) in low-income settings. Using data from the Benefits and Risks of Iron Supplementation in Children (BRISC) trial, we examined cognitive development and neural indices of memory and attention in 11 month-old Bangladeshi children and their environmental, socio-demographic, and biological predictors. Methods At 8 months of age, 3300 children were randomized to iron syrup, multiple micronutrient supplementation, or placebo for 3 months. The main trial outcomes include child development measured using the Bayley Scales of Infant and Toddler Development (BSID)-III, anthropometry, haemoglobin, morbidity, and iron indices. EEG is being conducted to measure event-related brain potentials (ERPs) in a random subset of 250 children at 11 months of age. ERPs are measured in response to auditory and visual stimuli, using roving oddball and attention orienting tasks. Generalized linear mixed models estimated the predictors of BSID-derived cognitive development and EEG-derived neural indices of memory and attention. Potential predictors include psychosocial stimulation, anthropometry, haemoglobin, socio-economic status, food security, sex, and parental education. Additionally, we examined correlations between the BSID cognitive scores and EEG-derived neural indices of cognition. Results Preliminary BSID data up to December 2018 indicates that 1749 children have completed measurements at 11 months of age. Psychosocial stimulation was significantly associated with BSID cognitive development scores. ERPs in children at 11 months of age are expected to be completed by May 2019 and relevant results will be presented. Conclusions This study is the first to acquire ERP data in children at 11 months of age in rural Bangladesh. Our findings will identify significant predictors of cognitive functioning measured using the BSID (a well-established developmental test) and using EEG (a sensitive neurophysiological approach) in young children in this setting. Results will indicate the agreement between child cognition outcomes using the BSID and EEG. Funding Sources NHMRC and The University of Melbourne.

Abstract Background A lack of culturally appropriate tests hampers accurate assessment of cognition in remote Australian Aboriginal communities. In Arnhem Land, this study employed a community consultation process to evaluate commonly used Western tests of executive function, memory, attention, and visuospatial function. Methods An initial consultation process and a follow-up pilot study resulted in the rejection of some common tests, the development of new tests, and culturally adapted versions of others. In the subsequent 30-person main trial, adult Aboriginal volunteers were examined on nine tests, plus the Kimberly Indigenous Cognitive Assessment screen, and a brief literacy test. Results Executive function, memory, and attention tests were found to group separately after an exploratory principal components analysis. Correlations between new tests and similar Kimberly screen items were not significant, but ceiling effects may be relevant. Six of 13 test scores were found to correlate with the literacy measure. Conclusions A selection of cognitive tests were identified that Aboriginal people found culturally acceptable and engaging. In particular, Self-Ordered Pointing, Trail-Making, a verbal-switching task, and a new test “Which car?” show promise for further development. This work may contribute to the need for culturally appropriate cognitive testing in Aboriginal communities.
