RESUMO

BACKGROUND: Bariatric interventions (BI, including surgical interventions) are effective in patients with massive obesity, i.e., a body mass index (BMI) > 40, and their number has steadily increased during the past decade. Yet, the stability of improvements in quality of life (QoL) in post-interventional patients is understudied and restricted to studies with small samples and short follow-ups. METHODS: Patients with BI between 2004 and 2018 were identified in a health claims database and invited to fill in a survey, comprising sociodemographic and lifestyle information and psychometric scales. QoL was assessed with the Bariatric QoL (BQL) scale with lower scores denoting worse QoL. BMI and excess weight loss (EWL) were calculated for the time soon after intervention (EWL-T1) and when filling the survey (EWL-T2). RESULTS: The majority of n = 2151 patients were female (80.7 %), had a mean age of 54.5 years and a mean BMI of 34.8. The mean EWL-T1 was 79 % (EWL-T2: 64.6 %). The mean BQL score was 47.6 and decreased with BMI (18.5-24.9: 52.6 vs. >40: 38.7), EWL-T2 (>66 %: 51.3 vs. <65 %: 42.1) and years since intervention (3-4: 48.2 vs >8: 45.1, each p < .001). For EWL-T1, the association between higher EWLs and higher BQL scores was stronger in females than in males (p < .005); for EWL at T2, both sexes did not differ in this regard (p = .848). Among normal-weight persons, males scored significantly lower on the BQL than females (44.9 vs. 54.9). CONCLUSIONS: Post-interventional QoL improvements diminish over time and depend on the weight loss, with significant differences between men and women.

RESUMO

BACKGROUND: Measures of dynamic changes in affect/emotions (variability, instability, inertia) have been linked to anxiety disorders (AD). We examine dynamics in affect, cognition and behavior in youth with current and remitted AD. METHODS: Mental disorders were assessed in a general population sample (N = 1180, age 14-21; Dresden, Germany) using standardized interview. Ecological Momentary Assessment of real-life affect, cognition and behavior took place eight times/day for four days. RESULTS: Individuals with current AD (n = 65) compared to healthy controls (HC, n = 531) revealed heightened variability of anxious and manic symptomatology, experiential avoidance, optimism and positive thoughts. Remitted AD (n = 52) showed lower variability of anxious and manic symptomatology and positive thoughts compared to current AD, while no differences were found compared to HC. Current AD and HC differed significantly in instability. Remitted AD showed lower instability of all constructs except for anger than current AD, and higher instability on all constructs except for positive and negative thoughts compared to HC. Current AD showed higher inertia of anger and negative thoughts than HC, and less inertia of positive thoughts than remitted AD. DISCUSSION: AD in youths is particularly linked to higher variability and instability of intertwined emotion-related experiences that partly persist after remission, informing emotion regulation models and interventions.

RESUMO

OBJECTIVES: Most of the observed associations of generalized anxiety disorder (GAD), social anxiety disorder (SAD) and major depressive disorder (MDD) with cortisol concentrations came from clinical and adult study samples, with inconsistent findings, partly due to method variance. We examined cross-sectional and longitudinal associations between GAD, SAD and MDD with saliva and hair cortisol as well as hair cortisol change in a population-based sample of adolescents and young adults, considering relevant co-factors. DESIGN: Epidemiological cohort study in Dresden, Germany. Data of 1050 individuals (mean age: 17.2 years) assessed at baseline (11/2015-12/2016) and of 605 individuals assessed at 1-year follow-up (FU1) are used. METHODS: Multivariable regression models were implemented to assess cross-sectional and longitudinal associations of DSM-5 defined 12-month diagnoses of GAD, SAD, and MDD, with short-term (saliva cortisol: cortisol awakening response (CAR) and area under the curve (AUC) as total cortisol) and long-term (hair cortisol) cortisol indices. Multivariable models were adjusted for age or "tanner" stage, waist circumference, tobacco and alcohol consumption, physical inactivity, and hair cortisol dependent confounder. Sex-specific analyses were additionally conducted. RESULTS: Cross-sectional analyses revealed positive associations between SAD and baseline saliva cortisol in multivariable models (CAR: ß-coefficient: 0.12; 95% CI: 0.01; 0.23) but could not be confirmed after adjusting for "tanner" stage or comorbid depression. Cross-sectional analyses concerning GAD and MDD in the full baseline sample yielded no significant associations. Sex-specific linear models revealed a significant inverse cross-sectional association between MDD (ß-coefficient: - 2.21; 95% CI: - 3.64; - 0.79) as well as SAD (ß-coefficient: - 2.21; 95% CI: - 4.03; - 0.38) with baseline hair cortisol in males, but not in females. In longitudinal analyses, no significant associations were found in the fully adjusted model, except for a positive association between hair cortisol change between baseline and FU1 and FU1-SAD (OR: 1.07; 95% CI: 1.02; 1.12). CONCLUSIONS: Results confirmed sex-specificity and the role of pubertal development in the association between cortisol with SAD and MDD, while no association emerged regarding cortisol and GAD. Future research in adolescents focusing on the role of cortisol in the pathogenesis of anxiety and depressive disorders would benefit from considering factors like sex-specificity and puberty development as well as comorbidity.

RESUMO

BACKGROUND: Prior research indicated, based on retrospective assessments of symptomatology, that 25% of individuals with "remitted" anxiety disorders (AD) experience a relapse. The present study used ecological momentary assessment (EMA) to examine how ADs affect everyday life among community adolescents and young adults with current or remitted AD compared to healthy controls and to each other. METHODS: Data come from the baseline assessment of the epidemiological Behavior and Mind Health study, conducted in Dresden (Germany) from 11/2015-12/2016. The sub-sample analyzed (n = 648, age 14-21) consisted of 65 participants with current DSM-5 AD-diagnosis, 52 participants with lifetime AD-diagnosis but not within the last 6 months (remitted), and 531 healthy controls (no psychopathology; healthy controls [HC]). EMA of various constructs took place 8 times a day for 4 days. RESULTS: The highest levels of symptoms were reported by those with current AD, followed by remitted AD and HC. Regression analyses revealed significantly worse mood, self-efficacy, quality of life and sleep-quality and more experiential avoidance, stress, negative thoughts and pessimism in remitted and current AD compared to HC. Current AD additional differed significantly from HC in optimism and positive thoughts. Furthermore, individuals with remitted AD without comorbidities differed significantly from HC on five out of 16 constructs. CONCLUSION: Not only current but also remitted AD is associated with diverse negative experiences in everyday life, which cannot merely be explained by comorbidities. As the remaining burden and impairment in individuals with remitted AD might contribute to relapse, interventions might be targeted to improve mental health.

RESUMO

BACKGROUND: Previous work on gene-environment (GxE) interplay concerning anxiety has focused on the interaction of 5-HTTLPR with childhood adversities or traumatic events whereas the impact of recent stressors is understudied, as is the integration of resilience. The current study aimed to investigate the interactive effect of 5-HTTLPR and recent stress on anxiety in adolescents considering resilience as buffer of a GxE risk constellation. METHOD: In a random population-based sample of 14-21 years old from Dresden, Germany, (N = 1180; genotyped = 942) recent stress (Daily Hassles [DH] Scale, Perceived Stress Scale, Screening Scale of the Trier Inventory for the Assessment of Chronic Stress), resilience (Connor-Davidson resilience scale) and anxiety (Patient Reported Outcome Measurement Information System Anxiety Short Form) were assessed via questionnaire in 2015 or 2016. RESULTS: Fractional regression models revealed that resilience interacted with recent stress in form of DH as well as recent chronic stress and 5-HTTLPR regarding anxiety. Participants carrying the more active LA LA genotype reported consistently higher levels of anxiety when experiencing more DH or more recent chronic stress and having low levels of resilience. When the resilience scores were high, LA LA carriers reported the lowest anxiety scores despite DH or recent chronic stress. CONCLUSION: Findings revealed an interactive relationship between 5-HTTLPR genotype and recent stress suggesting resilience to function as an additional dimension buffering the impact of a GxE risk constellation. Early interventions to build resilience may be useful to prevent an escalation of distress and associated unfavorable health outcomes.

RESUMO

The ICD-11 includes a new definition of adjustment disorder (AjD). The present study aimed to examine interrater reliability, internal consistency, and construct validity of a new diagnostic interview module to assess ICD-11 AjD. Data from two studies that used a standardized diagnostic interview assessment (i.e., DIA-X/M-CIDI and updated DIA-X-5) were used. For interrater reliability, agreement indicators (i.e., κ) were calculated using data from the DIA-X-5 test-retest study (N = 60). To examine internal consistency and construct validity, Cronbach's alpha values and the Kuder-Richardson correlation coefficient were computed along with confirmatory factor and latent class analyses (LCA), using data from the Zurich Adjustment Disorder Study (N = 330). Interrater reliability analyses found an adjusted kappa of 0.807 for the ICD-11 AjD diagnosis. Few items from the impairment criterion of the diagnostic algorithm performed poorly. The internal consistency was acceptable, Cronbach's αs = .43-.80; the lower-bound estimate resulted from the two-item preoccupation symptom pattern. However, both items were significantly associated, OR = 3.14, 95% CI [1.97, 4.99]. Regarding LCA results, a two-class model was favored. We found that 94.3% of all ICD-11 AjD cases belonged to Class 2, OR = 23.69, 95% CI [7.15, 79.54], which was associated with subjectively rated distress, OR = 2.18, 95% CI [1.57, 3.02], and the external measure of the Brief Symptom Inventory global severity index, OR = 2.18, 95% CI [1.57, 3.02]. Overall, the new AjD interview module provided a reliable, valid assessment of the ICD-11 diagnosis; confirmation by other studies is needed.

RESUMO

BACKGROUND: There is a need of comprehensive standardized diagnostic assessment tools of psychopathology that match recent changes in diagnostic classification systems, such as the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Therefore, the computer-assisted DIA-X-5 was developed and its test-retest reliability was explored. The DIA-X-5 is based on the DIA-X/M-CIDI (Diagnostisches Expertensystem für psychische Störungen/Munich-Composite International Diagnostic Interview) which referred to the 4th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV). METHODS: A convenience sample (N = 60, age: 15-67) was interviewed twice with the computer-assisted DIA-X-5 interview, on average nine days apart, by trained and blinded interviewers. The DIA-X-5 is a standardized instrument for research purposes covering symptoms, syndromes and diagnoses from eleven classes of mental disorders according to the DSM-5 with matching F codes of the 10th edition of the International Classification of Diseases (ICD-10). RESULTS: Kappa values ranged from 0.90 for post-traumatic stress disorder to 0.30 for social anxiety disorder. For age of onset and age of recency, test-retest reliability as measured by intra-class correlation was satisfying with values above 0.90 for most disorders. CONCLUSIONS: Test-retest reliability of the DIA-X-5 syndromes and diagnoses were comparable to those of previous DSM-IV/DIA-X diagnoses for most disorders. Due to low case numbers for some diagnoses, further research in larger samples is required.

RESUMO

BACKGROUND: Evidence suggests that maternal anxiety is associated with adverse pregnancy and delivery outcomes, such as preterm birth, vaginal bleedings and low birth weight. AIMS: To examine the association of lifetime anxiety disorders and pregnancy-related anxiety and complications during pregnancy and delivery. STUDY DESIGN: Prospective-longitudinal study (MARI). SUBJECTS: N = 306 pregnant women who were investigated repeatedly during the peripartum period. OUTCOME MEASURES: Information on lifetime anxiety disorders was assessed using a dimensional score (lifetime anxiety liability index) based on the standardized Composite International Diagnostic Interview for Women (CIDI-V). Pregnancy-related anxiety was surveyed with the Pregnancy and Childbirth Related Fears (PCF) questionnaire. Common pregnancy (e.g. vaginal bleedings) and delivery complications (e.g. labor induction) were assessed via medical records, interviews and questionnaires. RESULTS: The global tests on the association between lifetime anxiety liability and pregnancy complications and on the association between pregnancy-related anxiety and pregnancy/delivery complications revealed significant associations. Further analyses revealed associations of lifetime anxiety liability with preterm labor (OR = 1.6, 95% CI = 1.2-2.0) as well as pregnancy-related anxiety with vaginal bleedings (OR = 1.4, 95% CI = 1.0-1.8), preterm labor (OR = 1.3, 95% CI = 1.0-1.7), gestational diabetes (OR 0.5, 95% CI = 0.2-0.9), labor induction (OR = 1.5, 95% CI = 1.1-1.9) and use of labor medication (OR = 1.6, 95% CI = 1.2-2.0). After adjustment for maternal age, maternal body mass index, maternal smoking, socioeconomic status (occupation, household income) and social support (cohabitation), the associations between pregnancy-related anxiety and labor induction as well as use of labor medication remained significant. CONCLUSIONS: Pregnancy-related anxiety should be regularly assessed and, if necessary, treated during (early) pregnancy to minimize risks for complications during delivery.

RESUMO

OBJECTIVES: The Behavior and Mind Health (BeMIND) study is a population-based cohort study of adolescents and young adults from Dresden, Germany. The aim is to investigate psychological and behavioral factors linked to a range of mental disorders and health behaviors and their interaction with social-environmental and genetic/biologic factors. METHODS: A random sample of 14-21 year olds was drawn from the population registry in 2015. The baseline investigation was completed 11/2015-12/2016 (N = 1,180). Assessments include standardized diagnostic interview, cognitive-affective tasks, questionnaires, biosamples, and ecologic momentary assessment in real life with combined actigraphic/geographic monitoring. In the family study component, parents completed similar assessments and provided information on child's early development. RESULTS: The participation rate (minimum response proportion) was 21.7%; the cooperation rate was 43.4%. Acceptance and completion of study components were high. General health data indicate that more than 80% reported no or only mild impairment due to mental or somatic health problems in the past year; about 20% ever sought treatment for mental health problems or chronic somatic illnesses, respectively. CONCLUSIONS: Data from BeMIND baseline and follow-up investigations will provide novel insights into contributors to health and disease as adolescents grow into adulthood.

RESUMO

Importance: Suicidal behavior is a leading cause of death among adolescents and young adults. In light of the ideation-to-action framework, the delineation of frequency and temporal characteristics of such behavior during this developmental period is crucial. Objectives: To provide lifetime and 12-month prevalence estimates of suicidal behavior, including ideation, plan, and attempt, in adolescents and young adults of the general population, and to provide information about age at onset, temporal characteristics of suicidal behavior, including duration (number of years between onset and last occurrence) and frequency (number of episodes), and transition patterns across suicidal behaviors. Design, Setting, and Participants: A cross-sectional epidemiological study was conducted in a random community sample of 1180 adolescents and young adults aged 14 to 21 years assessed in 2015 to 2016 in Dresden, Germany. Data analysis was performed from October 2018 to March 2019. Main Outcomes and Measures: Lifetime and 12-month suicidal behavior (ideation, plan, and attempt) were assessed with a standardized diagnostic interview (Munich-Composite International Diagnostic Interview) by trained clinical interviewers. The onset, frequency, and duration of suicidal behavior were assessed by questionnaire. Results: Of the 1180 participants (495 male [weighted percentage, 51.7%]; mean [SD] age, 17.9 [2.3] years), 130 participants (10.7%; 95% CI, 9.0%-12.8%), 65 participants (5.0%; 95% CI, 3.9%-6.5%), and 41 participants (3.4%; 95% CI, 2.4%-4.7%) reported lifetime suicidal ideation, plan, and attempt, respectively. Any lifetime suicidal behavior was reported by 138 participants (11.5%; 95% CI, 9.7%-13.7%). Age-specific cumulative incidence estimates indicated an increase in suicidal behavior during adolescence, starting at age 10 years (<1%), increasing slightly until the age of 12 years (2.2%), and then increasing sharply thereafter until age 20 years (13.5%). There were different patterns among female and male participants for ideation, plan, and attempt, with an overall higher incidence among female participants for ideation (hazard ratio, 1.51; 95% CI, 1.02-2.22; P = .04), for plan (hazard ratio, 3.31; 95% CI, 1.72-6.36; P < .001), and, among those older than 14 years, for attempt (hazard ratio, 3.07; 95% CI, 1.11-8.49; P = .03). Of those with suicidal ideation, 66.0% reported persistent or recurrent ideation over more than 1 year with 75.0% reporting more than 1 episode. Of the participants with lifetime suicidal ideation, 47.0% reported a suicide plan and 23.9% reported a suicide attempt. The transition to suicide plan or attempt occurred mainly in the year of onset of suicidal ideation or plan; of those who transitioned, 74.9% transitioned from ideation to plan, 71.2% transitioned from ideation to attempt, and 85.4% transitioned from plan to attempt in the same year. Conclusions and Relevance: There is an urgent public health need for timely identification of suicidal behavior in adolescents and young adults to terminate persistent or recurrent suicidal tendencies and to interrupt the ideation-to-action transition.

RESUMO

Previous magnetic resonance imaging (MRI) studies revealed structural-functional brain reorganization 12 months after gastric-bypass surgery, encompassing cortical and subcortical regions of all brain lobes as well as the cerebellum. Changes in the mean of cluster-wise gray/white matter density (GMD/WMD) were correlated with the individual loss of body mass index (BMI), rendering the BMI a potential marker of widespread surgery-induced brain plasticity. Here, we investigated voxel-by-voxel associations between surgery-induced changes in adiposity, metabolism and inflammation and markers of functional and structural neural plasticity. We re-visited the data of patients who underwent functional and structural MRI, 6 months (n = 27) and 12 months after surgery (n = 22), and computed voxel-wise regression analyses. Only the surgery-induced weight loss was significantly associated with brain plasticity, and this only for GMD changes. After 6 months, weight loss overlapped with altered GMD in the hypothalamus, the brain's homeostatic control site, the lateral orbitofrontal cortex, assumed to host reward and gustatory processes, as well as abdominal representations in somatosensory cortex. After 12 months, weight loss scaled with GMD changes in right cerebellar lobule VII, involved in language-related/cognitive processes, and, by trend, with the striatum, assumed to underpin (food) reward. These findings suggest time-dependent and weight-loss related gray matter plasticity in brain regions involved in the control of eating, sensory processing and cognitive functioning.

RESUMO

There is increased interest in whether bariatric surgeries such as Roux-en-Y gastric bypass (RYGB) achieve their profound weight-lowering effects in morbidly obese individuals through the brain. Hypothalamic inflammation is a well-recognized etiologic factor in obesity pathogenesis and so represents a potential target of RYGB, but clinical evidence in support of this is limited. We therefore assessed hypothalamic T2-weighted signal intensities (T2W SI) and fractional anisotropy (FA) values, 2 validated radiologic measures of brain inflammation, in relation to BMI and fat mass, as well as circulating inflammatory (C-reactive protein; CrP) and metabolic markers in a cohort of 27 RYGB patients at baseline and 6 and 12 months after surgery. We found that RYGB progressively increased hypothalamic T2W SI values, while it progressively decreased hypothalamic FA values. Regression analyses further revealed that this could be most strongly linked to plasma CrP levels, which independently predicted hypothalamic FA values when adjusting for age, sex, fat mass, and diabetes diagnosis. These findings suggest that RYGB has a major time-dependent impact on hypothalamic inflammation status, possibly by attenuating peripheral inflammation. They also suggest that hypothalamic FA values may provide a more specific radiologic measure of hypothalamic inflammation than more commonly used T2W SI values.

RESUMO

Alterations in volitional control have been found for various mental disorders. However, it remains unclear to which degree such alterations vary by type of psychopathology and constitute preceding vulnerabilities or correlates of mental disorders. DSM-IV mental disorders were assessed among adolescents and young adults from the community at baseline (age 14-24) and in up to 3 follow-up assessments over 10 years (n = 2515) using a standardized diagnostic interview (DIA-X/M-CIDI). Self-reported volitional control was assessed at second follow-up (T2) when subjects were aged 17-28 using the German version of the Short Form of the Volitional Components Inventory. Linear regressions adjusted for sex, age and lifetime disorders revealed that anxiety and affective disorders were associated with widespread alterations in self-reported volitional control (lower self regulation, higher self inhibition and volitional inhibition), while substance use disorders were specifically associated with higher volitional inhibition. Logistic regressions adjusted for sex, age and prior lifetime psychopathology revealed that lower self-reported volitional control at T2 predicted incident panic, social phobia and substance use at T3 (follow-up interval M = 4.8 years). Findings point toward at least partly disorder-specific alterations in volitional control in mental disorders, which might be antecedent vulnerability factors and thus useful to guide early recognition and prevention.

RESUMO

Bariatric surgery has become the gold standard for the treatment of morbid obesity (body mass index (BMI) ≥ 40 kg/m2), but only few studies investigated its plastic influences on the obese brain. In this longitudinal study, we combined structural and functional magnetic resonance brain imaging (MRI) in 27 patients (BMI 47.8 ± 5.5 kg/m2) undergoing gastric-bypass surgery and 14 non-obese matched controls (BMI 24.7 ± 3.4 kg/m2). Over the first year after surgery, patients presented widespread changes in white matter density (WMD) as well as gray matter density (GMD) in the cerebral cortex of all lobes, subcortical structures, the brainstem as well as the cerebellum, but no changes in white matter water diffusivity throughout the brain. Voxel-by-voxel regression analyses revealed that all GMD and WMD changes were well associated with elevated regional homogeneity of spontaneous neural activity (ReHo) in blood-oxygenation level-dependent signals. Spatial-temporal integration of structural and functional MRI suggests that gastric-bypass surgery induces widespread plastic changes in brain structure that concurrently homogenizes the functional profile of the cortex, subcortical regions as well as white matter structures.

RESUMO

BACKGROUND AND OBJECTIVES: Intolerance of uncertainty (IU) has been linked to Generalized Anxiety Disorder (GAD), but studies experimentally manipulating uncertainty have mostly failed to find differences between GAD patients and controls, possible due to a lack of distinction between uncertainty and ambiguity. This study therefore investigated reactivity to ambiguity in addition to uncertainty in high worriers (HW) and low worriers (LW). We hypothesized an interpretation bias between the groups during ambiguity tasks, while uncertainty would facilitate threat processing of subsequent aversive stimuli. METHODS: HW (N = 23) and LW (N = 23) completed a paradigm comprising the anticipation and perception of pictures with dangerous, safe, or ambiguous content. Anticipatory cues were certain (always correct information about the following picture) or uncertain (no information). Subjective ratings, reaction times and skin conductance responses (SCRs) were recorded. RESULTS: HW rated particularly ambiguous pictures as more aversive and showed longer reaction times to all picture conditions compared to LW. SCRs were also larger in HW compared to LW, particularly during uncertain but also safe anticipation. No group differences were observed during perception of stimuli. LIMITATIONS: All participants were female. HW was used as subclinical phenotype of GAD. CONCLUSIONS: Intolerance of ambiguity seems to be related to individual differences in worry and possibly to the development of GAD. Threat-related interpretations differentiating HW and LW occurred particularly for ambiguous pictures but were not accompanied by increased autonomic arousal during the picture viewing. This disparity between subjective rating and arousal may be the result of worrying in response to intolerance of uncertainty, restraining physiological responses.

RESUMO

Given a possible effect of estrogen on the pleasure-mediating dopaminergic system, musical appreciation in participants whose estrogen levels are naturally elevated during the oral contraceptive cycle and pregnancy has been investigated (n = 32, 15 pregnant, 17 nonpregnant; mean age 27.2). Results show more pronounced blood pressure responses to music in pregnant women. However, estrogen level differences during different phases of oral contraceptive intake did not have any effect, indicating that the observed changes were not related to estrogen. Effects of music on blood pressure were independent of valence, and dissonance elicited the greatest drop in blood pressure. Thus, the enhanced physiological response in pregnant women probably does not reflect a protective mechanism to avoid unpleasantness. Instead, this enhanced response is discussed in terms of a facilitation of prenatal conditioning to acoustical (musical) stimuli.

RESUMO

This study investigated the neural regions involved in blood pressure reactions to negative stimuli and their possible modulation by attention. Twenty-four healthy human subjects (11 females; age = 24.75 ± 2.49 years) participated in an affective perceptual load task that manipulated attention to negative/neutral distractor pictures. fMRI data were collected simultaneously with continuous recording of peripheral arterial blood pressure. A parametric modulation analysis examined the impact of attention and emotion on the relation between neural activation and blood pressure reactivity during the task. When attention was available for processing the distractor pictures, negative pictures resulted in behavioral interference, neural activation in brain regions previously related to emotion, a transient decrease of blood pressure, and a positive correlation between blood pressure response and activation in a network including prefrontal and parietal regions, the amygdala, caudate, and mid-brain. These effects were modulated by attention; behavioral and neural responses to highly negative distractor pictures (compared with neutral pictures) were smaller or diminished, as was the negative blood pressure response when the central task involved high perceptual load. Furthermore, comparing high and low load revealed enhanced activation in frontoparietal regions implicated in attention control. Our results fit theories emphasizing the role of attention in the control of behavioral and neural reactions to irrelevant emotional distracting information. Our findings furthermore extend the function of attention to the control of autonomous reactions associated with negative emotions by showing altered blood pressure reactions to emotional stimuli, the latter being of potential clinical relevance.

RESUMO

BACKGROUND: Premenstrual syndrome (PMS) is characterized by a cluster of psychological and somatic symptoms during the late luteal phase of the menstrual cycle that disappear after the onset of menses. Behavioral differences in emotional and cognitive processing have been reported in women with PMS, and it is of particular interest whether PMS affects the parallel execution of emotional and cognitive processing. Related to this is the question of how the performance of women with PMS relates to stress levels compared to women without PMS. Cortisol has been shown to affect emotional processing in general and it has also been shown that women with severe PMS have a particular cortisol profile. METHODS: We measured performance in an emotional conflict task and stress levels in women with PMS (n = 15) and women without PMS (n = 15) throughout their menstrual cycle. RESULTS: We found a significant increase (p = 0.001) in the mean reaction time for resolving emotional conflict from the follicular to the luteal cycle phase in all subjects. Only women with PMS demonstrated an increase in physiological and subjective stress measures during the luteal menstrual cycle phase. CONCLUSIONS: Our findings suggest that the menstrual cycle modulates the integration of emotional and cognitive processing in all women. Preliminary data are supportive of the secondary hypothesis that stress levels are mediated by the menstrual cycle phase only in women with PMS. The presented evidence for menstrual cycle-specific differences in integrating emotional and cognitive information highlights the importance of controlling for menstrual cycle phase in studies that aim to elucidate the interplay of emotion and cognition.
