BACKGROUND: The catechol-O-methyltransferase (COMT) gene is related to dopamine degradation and has been suggested to be involved in the pathogenesis of major depressive disorder (MDD). However, how this gene affects brain function properties in MDD is still unclear. METHODS: Fifty patients with MDD and 35 cognitively normal participants underwent a resting-state functional magnetic resonance imaging scan. A voxelwise and data-drive global functional connectivity density (gFCD) analysis was used to investigate the main effects and the interactions of disease states and COMT rs4680 gene polymorphism on brain function...

Previous studies indicate that lying consumes cognitive resources, especially working memory (WM) resources. Considering the dual functions that WM might play in lying: holding the truth-related information and turning the truth into lies, the present study examined the relationship between the information storage and processing in the lie construction. To achieve that goal, a deception task based on the old/new recognition paradigm was designed, which could manipulate two levels of WM load (low-load task using 4 items and high-load task using 6 items) during the deception process...

The traditional Indian medicine, Ayurveda, provides insights and practical solutions towards a healthy life style. Rasayana is a branch of Ayurveda known for preserving and promoting health, enhancing the quality of life and delaying the aging process. In the traditional knowledge, the Rasayana herb, Chlorophytum borivilianum (C. borivilanum) is regarded as a general health promoting tonic that delays aging and increases lifespan, cognitive function and physical strength. Aging is a complex and multifactorial physiological phenomenon that manifests itself over a wide range of biological systems, tissues, and functions...

Engaging in regular and appropriate physical activity confers health benefits at any age. For seniors, swapping the role of « sedentary » for « someone who's on the move » offers much more substantial benefits than any medication, and notably even starting at a dose of 10-15 minutes per day ! Any physician who cares for elderly patients must pursue the objective of encouraging physical activity that is integrated into daily life (e.g. walking, gardening, shopping). This article consists of a literature review concerning the evidence for the benefits of physical activity in seniors in terms of quality of life, longevity, maintenance of functional independence, and prevention of cognitive decline...

Executive function (EF) refers to a set of cognitive abilities involved in self-regulated behavior. Given the critical role of EF in cognition, strategies for improving EF have attracted intensive attention in recent years. Previous studies have explored the effects of abacus-based mental calculation (AMC) training on several cognitive abilities. However, it remains unclear whether AMC training affects EF and its neural correlates. In this study, participants were randomly assigned to AMC or control groups upon starting primary school...

The brain-gut-microbiota axis comprises an extensive communication network between the brain, the gut, and the microbiota residing there. Development of a diverse gut microbiota is vital for multiple features of behavior and physiology, as well as many fundamental aspects of brain structure and function. Appropriate early-life assembly of the gut microbiota is also believed to play a role in subsequent emotional and cognitive development. If the composition, diversity, or assembly of the gut microbiota is impaired, this impairment can have a negative impact on host health and lead to disorders such as obesity, diabetes, inflammatory diseases, and even potentially neuropsychiatric illnesses, including anxiety and depression...

PurposePREPL deficiency causes neonatal hypotonia, ptosis, neonatal feeding difficulties, childhood obesity, xerostomia, and growth hormone deficiency. Different recessive contiguous gene deletion syndromes involving PREPL and a variable combination of SLC3A1 (hypotonia-cystinuria syndrome), CAMKMT (atypical hypotonia-cystinuria syndrome), and PPM1B (2p21 deletion syndrome) have been described. In isolated PREPL deficiency, previously described only once, the absence of cystinuria complicates the diagnosis...

Despite how important it is to assess executive functioning in persons with Intellectual Disability (ID), instruments adapted and validated for this population are scarce. This study's primary goal was to find evidence for the validity of the ID version of the Tower of London (TOLDXtm) test in persons with mild (IDMi) and moderate (IDMo) levels of ID with Down Syndrome (DS). A multicenter study was carried out. Subjects (n = 63, ≥ 39 years old) had DS with mild (n = 39) or moderate ID (n = 24) with no minor neurocognitive disorder or Alzheimer's disease...

Mild TBI (mTBI) is brain trauma from an external impact with a loss of consciousness less than 30 minutes. MTBI results in several biopsychosocial impairments with pronounced cognitive deficits, thought to resolve within three months of injury. Previous research suggests that these impairments are due to a temporary inability to appropriately allocate neural resources in response to cognitive demands. Our study questioned this assumption and instead hypothesized that mTBI was associated with long-term neural disruptions and compromised brain structure integrity...

OBJECTIVE: Alcohol-impaired driving remains a serious public health concern despite the fact that drinking and driving risks are widely disseminated and well understood by the public. This research examines the motivational conditions under which providing risk information can exacerbate rather than decrease potential drinking drivers' willingness to drive while impaired. METHOD: In a hypothetical drinking and driving scenario, 3 studies investigated participants' self-reported likelihood of drinking and driving as a function of (a) accessibility of information regarding risk associated with drinking and driving, (b) motivation to drive, and (c) need for cognitive closure (NFC)...

Craig Hedge, Georgina Powell, Petroc Sumner
Individual differences in cognitive paradigms are increasingly employed to relate cognition to brain structure, chemistry, and function. However, such efforts are often unfruitful, even with the most well established tasks. Here we offer an explanation for failures in the application of robust cognitive paradigms to the study of individual differences. Experimental effects become well established - and thus those tasks become popular - when between-subject variability is low. However, low between-subject variability causes low reliability for individual differences, destroying replicable correlations with other factors and potentially undermining published conclusions drawn from correlational relationships...

Cognitive interventions may improve cognition, delay age-related cognitive declines, and improve quality of life for older adults. The current meta-analysis was conducted to update and expand previous work on the efficacy of cognitive interventions for older adults and to examine the impact of key demographic and methodological variables. EBSCOhost and Embase online databases and reference lists were searched to identify relevant randomized-controlled trials (RCTs) of cognitive interventions for cognitively healthy or mildly impaired (MCI) older adults (60+ years)...

PURPOSE OF REVIEW: We review recent advances in psychotherapies for depressed older adults, in particular those developed for special populations characterized by chronic medical illness, acute medical illness, cognitive impairment, and suicide risk factors. We review adaptations for psychotherapy to overcome barriers to its accessibility in non-specialty settings such as primary care, homebound or hard-to-reach older adults, and social service settings. RECENT FINDINGS: Recent evidence supports the effectiveness of psychotherapies that target late-life depression in the context of specific comorbid conditions including COPD, heart failure, Parkinson's disease, stroke and other acute conditions, cognitive impairment, and suicide risk...

Subjects at risk of dementia benefit from participation in mentally stimulating activities, but no prior studies have investigated similar associations in Parkinson disease (PD). The aim of this study was to investigate the relationship between times spent engaging in mentally stimulating activities and cognitive functions in PD while accounting for the degree of primary neurodegenerations. PD patients (N = 41, 33 males; age 68.5 ± 7.2; Hoehn and Yahr stage 2.6 ± 0.6) completed the Community Health Activities Model Program for Seniors questionnaire, mini-mental state examination (MMSE), and [(11)C]dihydrotetrabenazine dopaminergic and [(11)C]piperidinyl propionate acetylcholinesterase PET imaging...

The benefit of deep brain stimulation (DBS) in controlling the motor symptoms of Parkinson's disease is well established, however, the impact on the non-motor symptoms (NMS) remains to be elucidated, although the growing investigative efforts are promising. This article reviews the reported data and considers the level of evidence available with regard to the effect of DBS on NMS total burden and on the cognitive, neuropsychiatric, sleep, pain, dysautonomic, and weight domains. Multiple case series suggest that DBS improves the burden of NMS by reducing prevalence, intensity, and non-motor fluctuations...
