The relationship between cognitive enrichment and cognitive control: A systematic investigation of environmental influences on development through socioeconomic status.

We measured the impact of socioeconomic status (SES) on cognitive processes. We examined cognitive control, specifically working memory (WM), in a sample of N = 141 7- to 17-year-olds using rule-guided behavior tasks. Our hypothesis is based on computational modeling data that suggest that the development of flexible cognitive control requires variable experiences in which to implement rule-guided action. We found that not all experiences that correlated with SES in our sample impacted task performance, a...

Depression related cerebral pathology and its relationship with cognitive functioning: A systematic review.

Depression's relationship with cerebral abnormalities and cognitive decline is temporally dynamic. Despite clear clinical utility, understanding depression's effect on cerebral structures, cognitive impairment and the interaction between these symptoms has had limited consideration.

Computerized Cognitive Training for the Neurocognitive Complications of HIV Infection: A Systematic Review.

The synergistic effects of HIV and aging on the brain may compromise cognitive reserve, resulting in HIV-associated neurocognitive disorder. The neuroscience literature suggests that computerized cognitive training programs represent a practical strategy to protect or remediate cognitive functioning in older adults. Such cognitive training programs may hold similar therapeutic benefits for adults living with HIV. This systematic review evaluated the effects of cognitive training interventions in adults livi...

Cognitive Therapy for Dementia Patients: A Systematic Review.

Cognitive therapy is a well-established intervention for treating elderly suffering from dementia. In particular, reality orientation and skills training seem to be effective interventions for reversing cognitive impairment among elderly, although findings are inconclusive. Therefore, a systematic update of the existing evidence of cognitive therapy for people suffering from dementia is needed.

Uncovering the association between fatigue and fatigability in multiple sclerosis using cognitive control.

Fatigue and cognitive dysfunction are two common symptoms experienced by patients with multiple sclerosis (MS). The relationship between subjective and objective fatigue (fatigability) in MS is poorly understood. Cognitive control tasks might be more conducive to fatigability and more likely to show associations between subjective and objective cognitive fatigue in MS.

Relationship between mobility and cognitive impairment in patients with Alzheimer's disease.

Alzheimer's disease (AD) is usually accompanied by impairments to mobility, performance of the basic activities of daily life (ADL), and progressive cognitive decline. We analyzed the relationship between cognitive performance and related cognitive subdomains and mobility.

Anterior insular cortex is a bottleneck of cognitive control.

Cognitive control, with a limited capacity, is a core process in human cognition for the coordination of thoughts and actions. Although the regions involved in cognitive control have been identified as the cognitive control network (CCN), it is still unclear whether a specific region of the CCN serves as a bottleneck limiting the capacity of cognitive control (CCC). Here, we used a perceptual decision-making task with conditions of high cognitive load to challenge the CCN and to assess the CCC in a function...

Sleep deprivation differentially affects subcomponents of cognitive control.

Although sleep deprivation has long been known to negatively affect cognitive performance, the exact mechanisms through which it acts and what cognitive domains are impacted most is still disputed. The current study provides a theory-driven approach to examine and explain the detrimental effects of sleep loss with a focus on attention and cognitive control.

The relationship between second language acquisition and nonverbal cognitive abilities.

We monitored the progress of 40 children when they first started to acquire a second language (L2) implicitly through immersion. Employing a longitudinal design, we tested them before they had any notions of an L2 (Time 0) and after 1 school year of L2 exposure (Time 1) to determine whether cognitive abilities can predict the success of L2 learning. Task administration included measures of intelligence, cognitive control, and language skills. Initial scores on measures of inhibitory control seemed predictiv...

Divergence of subjective and performance-based cognitive gains following cognitive training in schizophrenia.

Cognitive training is effective for improving cognitive performance among people with schizophrenia. An individual's perception of their own cognition is dissociable from performance on objective cognitive tests. Since subjective cognitive benefit may impact engagement, motivation, and satisfaction with time-intensive cognitive interventions, this study aimed to determine whether subjective cognitive difficulties improve in conjunction with cognitive gains following 30 h of cognitive training.

Social isolation, cognitive reserve, and cognition in healthy older people.

There is evidence to suggest that social isolation is associated with poor cognitive health, although findings are contradictory. One reason for inconsistency in reported findings may be a lack of consideration of underlying mechanisms that could influence this relationship. Cognitive reserve is a theoretical concept that may account for the role of social isolation and its association with cognitive outcomes in later life. Therefore, we aimed to examine the relationship between social isolation and cogniti...

Genome-wide analysis reveals extensive genetic overlap between schizophrenia, bipolar disorder, and intelligence.

Schizophrenia (SCZ) and bipolar disorder (BD) are severe mental disorders associated with cognitive impairment, which is considered a major determinant of functional outcome. Despite this, the etiology of the cognitive impairment is poorly understood, and no satisfactory cognitive treatments exist. Increasing evidence indicates that genetic risk for SCZ may contribute to cognitive impairment, whereas the genetic relationship between BD and cognitive function remains unclear. Here, we combined large genome-w...

Cognitive Training Does Not Enhance General Cognition.

Due to potential theoretical and societal implications, cognitive training has been one of the most influential topics in psychology and neuroscience. The assumption behind cognitive training is that one's general cognitive ability can be enhanced by practicing cognitive tasks or intellectually demanding activities. The hundreds of studies published so far have provided mixed findings and systematic reviews have reached inconsistent conclusions. To resolve these discrepancies, we carried out several meta-an...

The course and prognostic factors of cognitive outcomes after traumatic brain injury: a systematic review.

Despite indications that TBI may be a precursor of cognitive decline and subsequent development of Alzheimer's disease, little is known about the time course of this relationship and the factors involved. This systematic review summarizes the evidence pertinent to this subject matter. All English language studies of longitudinal design, and works cited within them, found in six literature databases, were considered, and their quality assessed. Of 65 articles appraised, 44 studies were selected. Results were...

Methamphetamine use and cognitive function: A systematic review of neuroimaging research.

Long-term use of MA has been associated with cognitive dysfunction in several domains. Neuroimaging studies have also reported structural, metabolic, and functional changes in MA users. However, no systematic review has been conducted on those studies in MA users that combined neuroimaging and cognitive tasks.

Background EEG features and prediction of cognitive outcomes in very preterm infants: A systematic review.

Very preterm infants are at risk of cognitive impairment, but current capacity to predict at-risk infants is sub-optimal. Electroencephalography (EEG) has been used to assess brain function in development. This review investigates the relationship between EEG and cognitive outcomes in very preterm infants.

Relationship between Cognitive Remediation and Evaluation Tools in Clinical Routine.

Many clinicians do not have adequate knowledge and interest in assessing cognitive deficits in psychiatric patients. However, these deficits are crucial and key symptoms, which can lead to impairment of quality of life, worsening of symptoms of disorders and difficulties in social, family and work relationships. Another limitation to the assessment of cognitive deficits is the poor maneuverability and practicality of the main cognitive assessment tools. Because there are no appropriate pharmacological appro...

The clinical relationship between cognitive impairment and psychosocial functioning in major depressive disorder: A systematic review.

Cognitive deficits are frequently observed in major depressive disorder (MDD), as well as impaired long-term psychosocial functioning. However, the relationship between cognitive deficits and psychosocial functioning in MDD is under-investigated. We aim to systematically review the literature on the relationship between specific cognitive impairments and psychosocial functioning in MDD. We systematically reviewed English-language literature in PubMed, PsychINFO, Scopus and Web of Science using search terms ...

Cognitive task modality influences postural control during quiet standing in healthy older adults.

The interstimulus interval of a cognitive task was found to have a limited effect on postural control in young adults, while visual cognitive tasks were found to improve stability compared to auditory tasks. It is of interest to investigate whether postural control in healthy older adults is sensitive to these types of cognitive task manipulations.

Differential engagement of cognitive control regions and subgenual cingulate based upon presence or absence of comorbid anxiety with depression.

Major depressive disorder (MDD) and anxiety disorders are highly comorbid, sharing many similar symptoms, including impairments in cognitive control. Deficits in cognitive control could be a potential mechanism underlying impaired emotion regulation in mood disorders.

Amyloid burden identifies neuropsychological phenotypes at increased risk of progression to Alzheimer's disease in mild cognitive impairment patients.

The extent of amyloid burden associated with cognitive impairment in amnestic mild cognitive impairment is unknown. The primary aim of the study was to determine the extent to which amyloid burden is associated to the cognitive impairment. The secondary objective was to test the relationship between amyloid accumulation and memory or cognitive impairment.

Preventing Cognitive Decline in Black Individuals With Mild Cognitive Impairment: A Randomized Clinical Trial.

Mild cognitive impairment (MCI) is a transition state between normal cognitive aging and dementia that increases the risk for progressive cognitive decline. Preventing cognitive decline is a public health priority.

Evaluation of the directional relationship between handgrip strength and cognitive function: the Korean Longitudinal Study of Ageing.

recent studies suggest that handgrip strength is linked with cognitive impairment at older ages. However, it remains unclear as to whether muscular strength influences subsequent cognitive performance, or whether lower levels of cognitive function increase the likelihood of muscle strength decline.

Cross-sectional relationship between kynurenine pathway metabolites and cognitive function in major depressive disorder.

Cognitive impairment is common among patients with major depressive disorder (MDD), but its pathological mechanism is complex and not fully understood. Evidence suggests that the kynurenine (KYN) pathway may be implicated in the pathophysiology of depression, but few studies have explored the association between the KYN pathway and cognitive impairment in MDD. Our aim was to examine the relationship between cognitive impairment and KYN pathway metabolites in patients with MDD.

Relationship between blood pressure variability and cognitive function in geriatric hypertensive patients with well-controlled blood pressure.

Hypertension is an important risk factor for cardiovascular diseases and cognitive function. Blood pressure (BP) variability has been associated with cognitive dysfunction, but data are sparse regarding the relationship between BP variability and cognitive function in geriatric patients with well-controlled BP.
