PURPOSE: This study aimed to explore different aspects of executive function in patients with acromegaly and investigate the cause of dysexecutive syndrome in these patients. METHODS: We conducted five typical executive function tests (Stroop test, verbal fluency [VF] test, Hayling Sentence Completion Test [HSCT], N-back test, and Sustained Attention to Response Task [SART]) on 42 acromegalic patients and 42 strictly matched healthy controls. Comparative analyses were conducted for five major executive function domains...

OBJECTIVE: Most smokers want to quit but most cessation attempts end in failure. Alcohol consumption is associated with smoking behavior and relapse. We examined the associations between severity of drinking and psychological processes during a cessation attempt in the laboratory and during a quit attempt. METHODS: Smokers (N=209) enrolled in a smoking cessation study were followed from 2 weeks pre-quit through 4 weeks post-quit. Participants scoring 0-7 and 8-15 on the Alcohol Use Disorders Identification Test (AUDIT) were classified as low-risk and high-risk drinkers, respectively...

INTRODUCTION: Paratrooper training courses are very demanding, leading to a high number of drop-outs, despite existing selection criteria. This study investigated physiological, neuropsychological, and subjective data of completers and drop-outs during paratrooper training to identify potential predictive indices. METHODS: Tested were 24 paratrooper soldiers before (t0), after 8 wk (t1), and at the end of a 12-wk training camp (t2). There were 11 soldiers who completed the course and 13 dropped out...

Objective: Anxiety as a uni- or multidimensional construct has been under discussion. The unidimensional approach assumes that there is a general trait anxiety, which predisposes the individuals to increases in state anxiety in various threatening situations. In this case, there should be a correlation between state and trait anxiety in any situation of threat. Therefore, the aim of this study was to investigate the correlation between trait and state anxiety in participants exposed to two different anxiogenic situations: interpersonal threat (Video-Monitored Stroop Test - VMST) and physical threat (third molar extraction - TME)...

BACKGROUND: Older adults are encouraged to participate in regular physical activity to counter the age-related declines in physical and cognitive health. Literature on the effect of different exercise training modalities (aerobic vs resistance) on these health-related outcomes is not only sparse, but results are inconsistent. In general, it is believed that exercise has a positive effect on executive cognitive function, possibly because of the physiological adaptations through increases in fitness...

Testosterone plays an important role in social threat processing. Recent evidence suggests that testosterone administration has socially anxiolytic effects, but it remains unknown whether this involves early vigilance or later, more sustained, processing-stages. We investigated the acute effects of testosterone administration on social threat processing in 19 female patients with Social Anxiety Disorder (SAD) and 19 healthy controls. Event-related potentials (ERPs) were recorded during an emotional Stroop task with subliminally presented faces...

The very low-frequency (VLF) band of heart rate variability (HRV) has different characteristics compared with other HRV components. Here we investigated differences in HRV changes after a mental stress task. After the task, the high-frequency (HF) band and ratio of high- to low-frequency bands (LF/HF) immediately returned to baseline. We evaluated the characteristics of VLF band changes after a mental stress task. We hypothesized that the VLF band decreases during the Stroop color word task and there would be a delayed recovery for 2 h after the task (i...

Ageing is associated with the deterioration of all cognitive functions, including attention, memory and psychomotor speed. It has not yet been clearly confirmed whether the effects of cognitive and physical interventions can improve activities of daily living (ADL). This study compared the effectiveness of cognitive and physical training on cognitive functions and the transfer to ADL. Eighty older people with mild cognitive impairment (mean age 67.07 ± 4.3 years) were randomly divided into an experimental group (n = 40) and a control group (n = 40)...

Inhibitory tagging (IT), a flexible central control mechanism based on the current task goals, reduces the cognitive conflict effect at the cued location by blocking the incompatible stimulus-response (S-R) code. However, it is unknown whether IT has a similar effect on emotional conflict. Thus, we combined the face-word Stroop task with the manipulation of inhibition of return (IOR) and used event-related potential (ERP) technology to simultaneously examine the modulation effect of IT on emotional and cognitive conflict processing...

AIM OF THE STUDY: While migraine and obesity are related and associated with reduced executive functioning, no study has examined whether obesity exacerbates executive dysfunction in migraine. This cross-sectional study examined whether overweight/obesity moderated associations of migraine severity and associated features with inhibitory control, one aspect of executive function. MATERIALS AND METHODS: Women (n = 124) aged 18-50 years old with overweight/obesity (body mass index (BMI) = 35...

BACKGROUND: Although limited, the literature suggests alterations in activation of cognitive control regions in adults and adolescents with a history of childhood abuse. The current study examined whether such alterations are increased in the face of emotionally-distracting as compared to emotionally neutral information, and whether such alterations occur in brain regions that exert cognitive control in a more top-down sustained manner or a more bottom-up transient manner. METHODS: Participants were young adult women (ages 23-30): one group with a history of childhood physical or sexual abuse (N = 15) and one with no trauma exposure (N = 17), as assessed through the Trauma History Questionnaire and a two-stage interview adapted from the National Crime Victims Survey...

Cognitive control impairments may contribute strongly to the overall cognitive deficits observed in patients diagnosed with schizophrenia. In the current study we explore a specific cognitive control function referred to as conflict adaptation. Previous studies on conflict adaptation in schizophrenia showed equivocal results, and, moreover, were plagued by confounded research designs. Here we assessed for the first time conflict adaptation in schizophrenia with a design that avoided the major confounds of feature integration and stimulus-response contingency learning...

PURPOSE: Adolescents with cancer have unique developmental considerations. These include brain development, particularly in the frontal lobe, and a focus on completing education and entering the workforce. Cancer and treatment at this stage may prove to uniquely affect survivors' experience of cognitive and occupational function. METHODS: An exploratory, cross-sectional, descriptive comparative study was employed to describe cognitive and occupational function in adult survivors of adolescent cancer (diagnosed between the ages of 15 and 21 years) and explore differences in age- and gender-matched controls...

Neurocognitive dysfunctions are frequently identified in the addictions. These dysfunctions may indicate either diffuse dysfunction or may represent separate facets that have differential importance to the addiction phenotype. In a sample (n = 260) of alcohol and/or stimulant users and controls we measured responses across 7 diverse neurocognitive measures. These measures were Continuous Performance, Delay Discounting, Iowa Gambling, Stroop, Tower, Wisconsin Card Sorting, and Letter Number Sequencing. Comparisons were then made between the drug-dependent groups and controls using analysis of variance and also using a machine learning approach to classify participants based on task performance as substance-dependent or controls in 1 tree and as alcohol and/or stimulant users or controls in a second tree...

INTRODUCTION: Obsessive-Compulsive Disorder (OCD) is a complex and heterogeneous neuropsychiatric syndrome. Contamination obsessions and washing/cleaning compulsions are the most frequent clinical OCD subtypes. The current study aimed at examining the neuropsychological impairments in drug-naive obsessive-compulsive (OC) washers without depressive symptoms and their association with the severity of symptoms. METHODS: In the current causal-comparative study, 35 patients with diagnostic and statistical mental disorders class (DSM)-IV diagnosed with washing-subtype OCD and 35 healthy subjects were selected by the convenience sampling method and evaluated by computerized neuropsychology battery and clinical tests as Stroop Color-Word Test (SCWT), Wisconsin Card Sorting Test (WCST), Go/No-Go Test, Digits Forward (DF), Digits Backward (DB), Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), and General Health Questionnaire (GHQ)-28...

OBJECTIVE: Impaired cognition has been reported in patients with congenital adrenal hyperplasia (CAH), although the findings have been conflicting. It has been hypothesized that the major causes of the deficits are prenatal hormonal imbalances and/or excessive glucocorticoid treatment. DESIGN, PATIENTS AND SETTING: This was an observational study comparing cognition in CAH patients (n=55) to control subjects from the general population (n=58), aged 16-33 years. Nine CAH subjects had been treated prenatally with dexamethasone...

OBJECTIVE: To investigate whether Pi (Spleen) qi-deficiency affected psychological and neural responses in relevance to cognitive control. METHODS: Pi qi-deficient and balanced participants were asked to perform the Stroop task, a classical cognitive control paradigm. In this paradigm, participants had to judge the color of the prompted word. The word's meaning indicated the color (the consistent condition) or not (the inconsistent condition), or were unrelated to the color (the neutral condition)...
