Cognitive impairments and recovery in patients with work-related stress complaints - four years later.

Patients on sick leave due to work-related stress often present with cognitive complaints. The primary aim of this prospective cohort study was to examine potential long-term consequences of previous ongoing work-related stress in terms of cognitive functioning four years after initial professional care seeking. We tested a group of patients with work-related stress complaints with a comprehensive neuropsychological test battery.

Anxiety and depression in Klinefelter syndrome: The impact of personality and social engagement.

Klinefelter syndrome (KS) (47, XXY) is the most common sex chromosome disorder, with a prevalence of 1 in every 660 newborn males. Despite the profound adverse effects of anxiety and depression, and their greater prevalence in KS populations, no research has been conducted to date to identify the determinants of anxiety and depression among patients with KS. We examined the relationships between personality traits, social engagement, and anxiety and depression symptoms among KS patients (n = 69) and a group of male controls (n = 69) matched for age and years of education.

Perceived stress, disturbed sleep, and cognitive impairments in patients with work-related stress complaints: a longitudinal study.

Patients on sick leave due to work-related stress often present with cognitive impairments as well as sleep disturbances. The aim of this longitudinal study was to examine the role of perceived stress and sleep disturbances in the longitudinal development in cognitive impairments in a group of patients with prolonged work-related stress (N = 60) during a period of 12 months following initial professional care-seeking. Objective cognitive impairments (neuropsychological tests) were measured on two occasions - at initial professional care-seeking and at 12-month follow-up.

The role of genes, intelligence, personality, and social engagement in cognitive performance in Klinefelter syndrome.

Introduction: The determinants of cognitive deficits among individuals with Klinefelter syndrome (KS) are not well understood. This study was conducted to assess the impact of general intelligence, personality, and social engagement on cognitive performance among patients with KS and a group of controls matched for age and years of education.

Methods: Sixty-nine patients with KS and 69 controls were assessed in terms of IQ, NEO personality inventory, the Autism Spectrum Quotient (AQ) scale, and measures of cognitive performance reflecting working memory and executive function.

Cognitive impairments in former patients with work-related stress complaints - one year later.

Patients on sick leave due to work-related stress often present with cognitive impairments. The aim of this prospective cohort study was to examine the long-term consequences of prolonged work-related stress in terms of cognitive functioning one year after initial professional care seeking. We tested a group of patients with work-related stress with a comprehensive neuropsychological test battery at two occasions, one year apart.

Changes in cognitive functions and cerebral grey matter and their associations with inflammatory markers, endocrine markers, and APOE genotypes in testicular cancer patients undergoing treatment.

Evidence suggests that testicular cancer (TC) and its treatment are associated with cognitive impairment. However, the underlying neural substrate and biological mechanisms are poorly understood. This study aimed to investigate changes in cognition and brain grey matter (GM) morphology in TC patients undergoing treatment, and to explore associations with immune markers, endocrine markers, and genotype.

Can memory and executive functions in patients with obsessive-compulsive disorder predict outcome of cognitive behavioural therapy?

Background: Most studies find that patients with obsessive-compulsive disorder (OCD) have impaired memory and executive functions. Cognitive behavioural therapy (CBT) is the recommended psychotherapeutic treatment of patients with OCD. We hypothesized that impairments in memory and executive functions would predict poor outcome of CBT.

Cognitive impairment and potential biological and psychological correlates of neuropsychological performance in recently orchiectomized testicular cancer patients.

Objective: The aim of this study was to determine the prevalence of cognitive impairment (CI) in newly diagnosed and orchiectomized testicular cancer (TC) patients prior to systemic treatment, and to explore biological and psychological correlates.

Methods: Sixty-six TC patients were compared with 25 healthy men on neuropsychological tests and a measure of cognitive complaints. CI status and a global composite score (representing overall neuropsychological performance) were calculated for each participant.

Cognitive impairment in testicular cancer survivors 2 to 7 years after treatment.

Purpose: The aim of the present study was to determine the prevalence of cognitive impairment (CI) in a group of testicular (TC) survivors by comparing their neuropsychological test scores with normative data and to assess their performance in specific cognitive domains.

Methods: Seventy-two TC survivors were evaluated 2 to 7 years post-treatment with a neuropsychological test battery that assessed multiple cognitive domains-attention and working memory, processing speed, verbal fluency, learning and memory, and executive functioning. Test scores were compared with normative data, and CI status was calculated for each participant.

Work-related stress is associated with impaired neuropsychological test performance: a clinical cross-sectional study.

Patients on sick leave due to work-related stress often complain about impaired concentration and memory. However, it is undetermined how widespread these impairments are, and which cognitive domains are most long-term stress sensitive. Previous studies show inconsistent results and are difficult to synthesize.

Anthropometry in Klinefelter syndrome--multifactorial influences due to CAG length, testosterone treatment and possibly intrauterine hypogonadism.

Context: Klinefelter syndrome, 47, XXY (KS), is underdiagnosed partly due to few clinical signs complicating identification of affected individuals. Certain phenotypic traits are common in KS. However, not all aspects of the KS phenotype are well described.

Are there reliable changes in memory and executive functions after cognitive behavioural therapy in patients with obsessive-compulsive disorder?

Introduction: Patients with obsessive-compulsive disorder (OCD) have impaired memory and executive functions, but it is unclear whether these functions improve after cognitive behavioural therapy (CBT) of OCD symptoms. The primary aim of this study was to investigate whether memory and executive functions change after CBT in patients with OCD.

Methods: We assessed 39 patients with OCD before and after CBT with neuropsychological tests of memory and executive functions.

Memory and executive functions in patients with obsessive-compulsive disorder.

Objective: We investigated whether patients with obsessive-compulsive disorder have poorer memory and executive functions than healthy controls.

Background: The relatively inconsistent previous findings on this question reflect a lack of well-matched control groups, the inclusion of patients with comorbidity, and the use of noncomparable neuropsychological tests to assess memory and executive functions.

Methods: We used well-accepted neuropsychological tests of memory and executive functions to assess 42 patients who had obsessive-compulsive disorder without comorbidity, and 42 healthy controls.

Cognitive status does not predict motor gain from post stroke constraint-induced movement therapy.

Background: Constraint-Induced Movement Therapy (CIMT) is an evidence-based rehabilitation intervention for stroke. Several factors influence the motor gain from CIMT, including age and level of impairment. However, it is currently unknown to what extent cognitive status affects motor gain during CIMT.

Neuroanatomical correlates of Klinefelter syndrome studied in relation to the neuropsychological profile.

Brain imaging in Klinefelter syndrome (47, XXY) (KS), a genetic disorder characterized by the presence of an extra X chromosome, may contribute to understanding the relationship between gene expression, brain structure, and subsequent cognitive disabilities and psychiatric disorders. We conducted the largest to date voxel-based morphometry study of 65 KS subjects and 65 controls matched for age and education and correlated these data to neuropsychological test scores. The KS patients had significantly smaller total brain volume (TBV), total gray matter volume (GMV) and total white matter volume (WMV) compared to controls, whereas no volumetric difference in cerebral spinal fluid (CSF) was found.

Do cognitive functions in obsessive-compulsive disorder change after treatment? A systematic review and a double case report.

Background: Neuropsychological and neuroimaging studies have documented that patients with obsessive-compulsive disorder (OCD) have cognitive difficulties dependent upon fronto-striatal circuits in the brain. It is, however, unclear whether the cognitive difficulties change after treatment. Answering this question could help establish whether cognitive difficulties in OCD are state dependent or more trait-like.

A systematic review of neuropsychological performance in social anxiety disorder.

Background: Over the past few years, there has been an increasing interest in the neuropsychological performance of patients with anxiety disorders, yet the literature does not provide a systematic review of the results concerning adult patients with social anxiety disorder (SAD).

Aims: The primary aim of this paper is to review the literature on neuropsychological performance in adult patients with SAD.

Methods: This paper is a systematic review of empirical studies investigating neuropsychological performance as assessed by cognitive tests.

The relationship between cognitive functions, somatization and behavioural coping in patients with multiple functional somatic symptoms.

Background And Aims: Patients with multiple functional somatic symptoms (MFS) often express cognitive complaints. The aim of this descriptive study was to investigate whether these patients have cognitive deficits and whether the patients' cognitive functioning relates to their experience of physical and psychological distress and to their use of pain-related coping strategies.

Methods: Neuropsychological assessment of verbal ability, psychomotor speed, attention, working memory, perceptual organization and memory, was conducted on 22 MFS patients and 27 healthy age- and gender-matched controls.

No effect of TETRA hand portable transmission signals on human cognitive function and symptoms.

Current radio frequency radiation exposure guidelines rest on well-established thermal effects. However, recent research into analogue and digital transmission fields at levels covered by the exposure guidelines has indicated possible detrimental effects on human cognitive performance. To investigate this, we conducted a controlled climate chamber study of possible changes in cognitive performance in healthy volunteers exposed to transmission signals from TETRA hand portables (TETRA handsets).

Long-term cognitive function following chemotherapy in patients with testicular cancer.

Cancer patients frequently report cognitive complaints following chemotherapy, but the results from the available studies, mainly of women with breast cancer, are inconsistent. Our aim was to compare cognitive function of men with testicular cancer (TC) who had orchiectomy and chemotherapy (bleomycin, etoposide, cisplatin) with men who had orchiectomy only or orchiectomy and radiotherapy. Thirty-six chemotherapy patients and 36 nonchemotherapy patients were tested 2-7 years after treatment for TC with standardized neuropsychological tests.

No indications of cognitive side-effects in a prospective study of breast cancer patients receiving adjuvant chemotherapy.

Objective: A number of cross-sectional studies have reported reduced cognitive function in cancer patients receiving chemotherapy compared with other cancer patients and healthy controls, suggesting that chemotherapy could be associated with cognitive side-effects. Recently published prospective studies question this hypothesis, but it is still unclear whether cancer patients should regard cognitive problems as a potential risk when receiving chemotherapy.

Methods: In the present study we examine whether cancer patients (n=34) receiving chemotherapy differed in cognitive changes during treatment compared with cardiac patients (n=12) and healthy controls (n=12) tested at 3-4 months interval.
