OBJECTIVES: Executive dysfunctions are frequently seen in patients with Major Depressive Disorder (MDD) and normalize in many cases during effective antidepressant therapy. This study investigated whether a normalization of executive dysfunctions during antidepressant treatment correlates with or can be predicted by clinical parameters or levels of brain-derived neurotrophic factor (BDNF). METHODS: In 110 MDD patients with executive dysfunctions (percentile < 16), executive functions and plasma BDNF levels were analysed at baseline, day 14 and 56 of an antidepressant treatment...

The concept of deep brain stimulation (DBS) for Parkinson's disease (PD) was introduced over 20 years ago, but our understanding of the nuances of this procedure continues to improve. The average motor outcomes of internal segment of the globus pallidus (GPi) and subthalamic nucleus (STN) DBS appear to be similar, although GPi DBS may allow greater recovery of verbal fluency and may provide greater relief of depression symptoms and improvement in the quality of life, and STN DBS appears more likely to result in decrease in levodopa equivalent doses...

BACKGROUND: There is a biologically plausible rationale whereby the dietary carotenoids lutein (L), zeaxanthin (Z), and meso-zeaxanthin (MZ), which are collectively referred to as macular pigment (MP) in the central retina (macula), support the maintenance of cognition via their antioxidant and anti-inflammatory properties. OBJECTIVE: To investigate the impact of supplemental L, Z, and MZ on memory, executive function, and verbal fluency among healthy individuals with low MP levels...

Using near-infrared spectroscopy, we examined changes in the concentration of oxygenated hemoglobin ([oxy-Hb]) in the frontal lobe during a verbal fluency task in 20 patients with schizophrenia (10 patients each receiving olanzapine [OLZ] and risperidone [RIS]) and 10 healthy controls. We found that [oxy-Hb] levels in the prefrontal region were higher in the patients receiving OLZ than in those receiving RIS. These results suggest that antipsychotic drugs have different effects on cerebral hemodynamic patterns, which may reflect frontal lobe function...

Introduction: Patients with obsessive compulsive disorder (OCD) have impaired cognitive functions, including attention, verbal and visual memory, and visual-spatial abilities as well as executive function But some studies did not show any disturbance in executive function of patients with OCD. To date, only few studies have been conducted on neuropsychological functioning of patients with panic disorder (PD). There are limited studies to reach a definite conclusion on executive functions of patients with OCD and those with PD...

BACKGROUND: In primary biliary cholangitis (PBC) fatigue is a major clinical challenge of unknown etiology. By demonstrating that fatigue in PBC is associated with an impaired cognitive performance, previous studies have pointed out the possibility of brain abnormalities underlying fatigue in PBC. Whether structural brain changes are present in PBC patients with fatigue, however, is unclear. To evaluate the role of structural brain abnormalities in PBC patients severely affected from fatigue we, therefore, performed a case-control cerebral magnetic resonance imaging (cMRI) study and correlated changes of white and grey brain matter with the cognitive and attention performance...

Research has demonstrated that bilingualism impacts neuropsychological performance, but the findings on its effects on verbal fluency have been mixed. This study compared the verbal fluency performance of non-Hispanic White monolingual speakers with a Hispanic bilingual population. Ninety-nine Spanish-English bilingual Hispanic and thirty English-speaking monolingual non-Hispanic White undergraduates completed the Controlled Oral Word Association Test (COWAT). Students also completed a general cognitive and English reading measure...

Cognitive functions are important correlates of health outcomes across the life-course. Individual differences in cognitive functions are partly heritable. Epigenetic modifications, such as DNA methylation, are susceptible to both genetic and environmental factors and may provide insights into individual differences in cognitive functions. Epigenome-wide meta-analyses for blood-based DNA methylation levels at ~420,000 CpG sites were performed for seven measures of cognitive functioning using data from 11 cohorts...

BACKGROUND: Photobiomodulation using low-level laser therapy (LLLT) has been tested as a new technique to optimize recovery of patients with traumatic brain injury (TBI). The aim of this study is to evaluate inhibitory attentional control after 18 sessions of active LLLT and compare with the placebo group (sham LLLT). Our exploratory analysis will evaluate the efficacy of the active LLLT on verbal and visuospatial episodic memory, executive functions (working memory, verbal and visuospatial fluency, attentional processes), and anxiety and depressive symptoms compared to the sham group...

Cognitive deficits are common in patients with systemic lupus erythematosus (SLE) regardless of overt neuropsychiatric involvement; however, a clear neuropsychological profile of SLE has not emerged. This study undertook a literature search of the PubMed, Scopus and Ovid (PsychINFO) databases for studies investigating cognitive alterations in SLE, using standardized neuropsychological (NP) measures. The data were analysed using meta-analytical procedures. The results support the observation that relative to healthy controls, SLE (regardless of overt neuropsychiatric involvement) is associated with statistically significant, small effect-sized deficits in visual attention, cognitive fluency, immediate visual memory and visual reasoning...

The apolipoprotein E epsilon 4 (ApoE4) allele is the strongest genetic risk factor for Alzheimer's disorder (AD) and is associated with semantic and episodic memory deficits. The aim of this study was to examine the associations between ApoE alleles (E2, E3, E4) and genotypes and neuropsychological tests, behavioral functions, and dementia symptoms as assessed using Consortium to Establish a Registry for Alzheimer's Disease (CERAD). This study included 60 patients with Alzheimer's disorder (AD), 60 with mild cognitive disorder (MCI), and 62 normal volunteers...

BACKGROUND: Cognitive and psychosocial impairment has been associated with increased levels of C-reactive protein (CRP) and homocysteine in bipolar disorder, but gender differences have seldom been studied. METHODS: Two hundred and twenty-four bipolar outpatients were included. Cognitive performance was assessed through the Screen for Cognitive Impairment in Psychiatry (SCIP). Psychosocial functioning was evaluated using the Functioning Assessment Short Test (FAST) and the General Assessment of Functioning (GAF)...

OBJECTIVE: Prospective studies on late-life anxiety disorders suggested that history of anxiety symptoms may be predictive of cognitive decline in old age. However, the relationship between anxiety and cognitive decline is still inconclusive due to heterogeneity in sample and methodology. This study was to explore how baseline anxiety symptoms associated with the change of memory in older people without cognitive impairment over a 3-year period. METHODS: This was a 3-year prospective study on 91 cognitively normal older adults with anxiety symptoms...

Older adults perform worse than younger adults when applying decision rules to choose between options that vary along multiple attributes. Although previous studies have shown that general fluid cognitive abilities contribute to the accurate application of decision rules, relatively little is known about which specific cognitive abilities play the most important role. We examined the independent roles of working memory, verbal fluency, semantic knowledge, and components of executive functioning. We found that age-related decline in applying decision rules was statistically mediated by age-related decline in working memory and verbal fluency...

The majority of proposed NIRS-BCIs has considered binary classification. Studies considering high-order classification problems have yielded average accuracies that are less than favorable for practical communication. Consequently, there is a paucity of evidence supporting online classification of more than two mental states using NIRS. We developed an online ternary NIRS-BCI that supports the verbal fluency task (VFT), Stroop task and rest. The system utilized two sessions dedicated solely to classifier training...

According to the 'use it or lose it' hypothesis, a lack of mentally challenging activities might exacerbate the loss of cognitive function. On this basis, retirement has been suggested to increase the risk of cognitive decline, but evidence from studies with long follow-up is lacking. We tested this hypothesis in a cohort of 3433 civil servants who participated in the Whitehall II Study, including repeated measurements of cognitive functioning up to 14 years before and 14 years after retirement. Piecewise models, centred at the year of retirement, were used to compare trajectories of verbal memory, abstract reasoning, phonemic verbal fluency, and semantic verbal fluency before and after retirement...
