Measurement of illumination exposure in postpartum women

BACKGROUND: Low levels of light exposure at critical times are thought to cause seasonal affective disorder. Investigators, in studies demonstrating the usefulness of bright light therapy, also have implicated light's role in non-seasonal depression. The precise cause of postpartum depression has not been delineated, but it seemed possible that new mothers would spend reduced time in daylight. The goal of this study was to examine the levels of illumination experienced by postpartum mothers and to discover any relationship between light exposure and mood levels experienced during the postpartum period. METHODS: Fifteen postpartum women, who did not have any baseline indication of depression, wore a wrist device (Actillume) for 72 hours to measure their exposure to light. At the end of the recording period, they completed a self-reported measure of mood. The mean light exposure of these postpartum women (expressed as the 24-hour average logarithm of illumination in lux) was compared with that of a representative sample of women of comparable age, residence, and seasonal months of recording. Mood levels were then rank-ordered and tested for correlation with light exposure levels. RESULTS: There was no significant difference between the amount of light [log(10)lux] experienced by postpartum (1.01 SD 0.236) and control women (1.06 SD 0.285). Mood was not correlated with illumination in the postpartum sample. CONCLUSIONS: Postpartum women in San Diego did not receive reduced light, nor was low mood related to low illumination

Bright green light treatment of depression for older adults [ISRCTN69400161]

BACKGROUND: Bright white light has been successfully used for the treatment of depression. There is interest in identifying which spectral colors of light are the most efficient in the treatment of depression. It is theorized that green light could decrease the intensity duration of exposure needed. Late Wake Treatment (LWT), sleep deprivation for the last half of one night, is associated with rapid mood improvement which has been sustained by light treatment. Because spectral responsiveness may differ by age, we examined whether green light would provide efficient antidepressant treatment in an elder age group. METHODS: We contrasted one hour of bright green light (1,200 Lux) and one hour of dim red light placebo (<10 Lux) in a randomized treatment trial with depressed elders. Participants were observed in their homes with mood scales, wrist actigraphy and light monitoring. On the day prior to beginning treatment, the participants self-administered LWT. RESULTS: The protocol was completed by 33 subjects who were 59 to 80 years old. Mood improved on average 23% for all subjects, but there were no significant statistical differences between treatment and placebo groups. There were negligible adverse reactions to the bright green light, which was well tolerated. CONCLUSION: Bright green light was not shown to have an antidepressant effect in the age group of this study, but a larger trial with brighter green light might be of value

Bright light treatment of depression for older adults [ISRCTN55452501]

BACKGROUND: The incidence of insomnia and depression in the elder population is significant. It is hoped that use of light treatment for this group could provide safe, economic, and effective rapid recovery. METHODS: In this home-based trial we treated depressed elderly subjects with bright white (8,500 Lux) and dim red (<10 Lux) light for one hour a day at three different times (morning, mid-wake and evening). A placebo response washout was used for the first week. Wake treatment was conducted prior to the initiation of treatment, to explore antidepressant response and the interaction with light treatment. Urine and saliva samples were collected during a 24-hour period both before and after treatment and assayed for aMT6s and melatonin respectively to observe any change in circadian timing. Subjects wore a wrist monitor to record light exposure and wrist activity. Daily log sheets and weekly mood (GDS) and physical symptom (SAFTEE) scales were administered. Each subject was given a SCID interview and each completed a mood questionnaire (SIGH-SAD-SR) before and after treatment. Also, Hamilton Depression Rating (SIGH-SAD version) interviews were conducted by a researcher who was blind to the treatment condition. A control group of healthy, age-matched, volunteers was studied for one day to obtain baseline data for comparison of actigraphy and hormone levels. RESULTS: Eighty-one volunteers, between 60 and 79 years old, completed the study. Both treatment and placebo groups experienced mood improvement. Average GDS scores improved 5 points, the Hamilton Depression Rating Scale (HDRS) 17 scores (extracted from the self-rated SIGH-SAD-SR) improved 6 points. There were no significant treatment effects or time-by-treatment interactions. No significant adverse reactions were observed in either treatment group. The assays of urine and saliva showed no significant differences between the treatment and placebo groups. The healthy control group was active earlier and slept earlier but received less light than the depressed group at baseline. CONCLUSION: Antidepressant response to bright light treatment in this age group was not statistically superior to placebo. Both treatment and placebo groups experienced a clinically significant overall improvement of 16%

Neurotrophic gene polymorphisms and response to psychological therapy

Therapygenetics, the study of genetic determinants of response to psychological therapies, is in its infancy. Here, we investigate whether single-nucleotide polymorphisms in nerve growth factor (NGF) (rs6330) and brain-derived neutrotrophic factor (BDNF) (rs6265) genes predict the response to cognitive behaviour therapy (CBT). Neurotrophic genes represent plausible candidate genes: they are implicated in synaptic plasticity, response to stress, and are widely expressed in brain areas involved in mood and cognition. Allelic variation at both loci has shown associations with anxiety-related phenotypes. A sample of 374 anxiety-disordered children with white European ancestry was recruited from clinics in Reading, UK, and in Sydney, Australia. Participants received manualised CBT treatment and DNA was collected from buccal cells using cheek swabs. Treatment response was assessed at post-treatment and follow-up time points. We report first evidence that children with one or more copies of the T allele of NGF rs6330 were significantly more likely to be free of their primary anxiety diagnosis at follow-up (OR=0.60 (0.42–0.85), P=0.005). These effects remained even when other clinically relevant covariates were accounted for (OR=0.62 (0.41–0.92), P=0.019). No significant associations were observed between BDNF rs6265 and response to psychological therapy. These findings demonstrate that knowledge of genetic markers has the potential to inform clinical treatment decisions for psychotherapeutic interventions

Neuroimaging in anxiety disorders

Neuroimaging studies have gained increasing importance in validating neurobiological network hypotheses for anxiety disorders. Functional imaging procedures and radioligand binding studies in healthy subjects and in patients with anxiety disorders provide growing evidence of the existence of a complex anxiety network, including limbic, brainstem, temporal, and prefrontal cortical regions. Obviously, “normal anxiety” does not equal “pathological anxiety” although many phenomena are evident in healthy subjects, however to a lower extent. Differential effects of distinct brain regions and lateralization phenomena in different anxiety disorders are mentioned. An overview of neuroimaging investigations in anxiety disorders is given after a brief summary of results from healthy volunteers. Concluding implications for future research are made by the authors

Self-stigma and quality of life in patients with depressive disorder: a cross-sectional study

Michaela Holubova,1,2 Jan Prasko,1 Marie Ociskova,1 Marketa Marackova,1 Ales Grambal,1 Milos Slepecky3 1Department of Psychiatry, Faculty of Medicine and Dentistry, Palacky University Olomouc, University Hospital Olomouc, Olomouc, 2Department of Psychiatry, Hospital Liberec, Liberec, Czech Republic; 3Department of Psychology Sciences, Faculty of Social Science and Health Care, Constantine the Philosopher University, Nitra, Slovak Republic Background: Self-stigma is a maladaptive psychosocial phenomenon that can affect many areas of patients&rsquo; lives and have a negative impact on their quality of life (QoL). This study explored the association between self-stigma, QoL, demographic data, and the severity of symptoms in patients with depressive disorder. Patients and methods: Patients who met the International Classification of Diseases, 10th revision, research criteria for depressive disorder were enrolled in this cross-sectional study. All outpatients completed the following measurements: the Quality of Life Enjoyment and Satisfaction Questionnaire, the Internalized Stigma of Mental Illness Scale, demographic questionnaire, and the objective and subjective Clinical Global Impression-Severity scales that measure the severity of disorder. A total of 81 depressive disorder patients (with persistent affective disorder &ndash; dysthymia, major depressive disorder, or recurrent depressive disorder) and 43 healthy controls participated in this study. Results: Compared with the healthy control group, a lower QoL was observed in patients with depressive disorder. The level of self-stigma correlated positively with total symptom severity score and negatively with QoL. Multiple regression analysis revealed that the overall rating of objective symptom severity and score of self-stigma were significantly associated with QoL. Conclusion: This study suggests a lower QoL in patients with depressive disorder in comparison with healthy controls and a negative impact of self-stigma level on QoL in patients suffering from depressive disorders.

Individual correlates of self-stigma in patients with anxiety disorders with and without comorbidities

Marie Ociskova,1,2 Jan Prasko,1 Dana Kamaradova,1 Ales Grambal,1 Zuzana Sigmundova1 1Department of Psychiatry, University Hospital in Olomouc, Faculty of Medicine and Dentistry, 2Department of Psychology, Faculty of Arts, Palacky University in Olomouc, Olomouc, Czech Republic Background: A number of psychiatric patients experience stigma connected to prejudices about mental disorders. It has been shown that stigma is most harmful when it is internalized. Most of the studies were performed on individuals either with psychoses or with mood disorders, and hence, there are almost no studies with other diagnostic categories. The goals of this research were to identify factors that are significantly related to self-stigma in patients with anxiety disorders and to suggest possible models of causality for these relationships.Methods: A total of 109 patients with anxiety disorders and possible comorbid depressive or personality disorders, who were admitted to the psychotherapeutic department participated in this study. All patients completed several psychodiagnostic methods, ie, the Internalized Stigma of Mental Illness Scale, Temperament and Character Inventory-Revised Version, Adult Dispositional Hope Scale, Dissociative Experiences Scale, Beck Anxiety Inventory, Beck Depression Inventory-Second Edition, and Clinical Global Impression (also completed by the senior psychiatrist).Results: The overall level of self-stigma was positively associated with a comorbid personality disorder, more severe symptomatology, more intense symptoms of anxiety and depression, and higher levels of dissociation and harm avoidance. Self-stigma was negatively related to hope, reward dependence, persistence, self-directedness, and cooperativeness. Multiple regression analysis showed that the most significant factors connected to self-stigma are harm avoidance, the intensity of depressive symptoms, and self-directedness. Two models of causality were proposed and validated. It seems that the tendency to dissociate in stress increases the probability of development of self-stigma, and this relationship is entirely mediated by avoidance of harm. Conversely, self-directedness lowers the probability of occurrence of self-stigma, and this effect is partly mediated by hope.Conclusion: Patients with anxiety disorders accompanied with or without comorbid depressive or personality disorders may suffer from self-stigma. Individuals with greater sensitivity to rejection and other socially aversive stimuli are prone to the development of self-stigma. Other personality factors, such as hopeful thinking and self-acceptance serve as factors promoting resilience concerning self-stigma.

Psychological factors and treatment effectiveness in resistant anxiety disorders in highly comorbid inpatients

Marie Ociskova, Jan Prasko, Klara Latalova, Dana Kamaradova, Ales Grambal Department of Psychiatry, Olomouc University Hospital, Faculty of Medicine and Dentistry, Palack&yacute; University Olomouc, Czech Republic Background: Anxiety disorders are a group of various mental syndromes that have been related with generally poor treatment response. Several psychological factors may improve or hinder treatment effectiveness. Hope has a direct impact on the effectiveness of psychotherapy. Also, dissociation is a significant factor influencing treatment efficiency in this group of disorders. Development of self-stigma could decrease treatment effectiveness, as well as several temperamental and character traits. The aim of this study was to explore a relationship between selected psychological factors and treatment efficacy in anxiety disorders. Subjects and methods: A total of 109 inpatients suffering from anxiety disorders with high frequency of comorbidity with depression and/or personality disorder were evaluated at the start of the treatment by the following scales: the Mini-International Neuropsychiatric Interview, the Internalized Stigma of Mental Illness scale, the Adult Dispositional Hope Scale, and the Temperament and Character Inventory &ndash; revised. The participants, who sought treatment for anxiety disorders, completed the following scales at the beginning and end of an inpatient-therapy program: Clinical Global Impression (objective and subjective) the Beck Depression Inventory &ndash; second edition, the Beck Anxiety Inventory, and the Dissociative Experiences Scale. The treatment consisted of 25 group sessions and five individual sessions of cognitive behavioral therapy or psychodynamic therapy in combination with pharmacotherapy. There was no randomization to the type of group-therapy program. Results: Greater improvement in psychopathology, assessed by relative change in objective Clinical Global Impression score, was connected with low initial dissociation level, harm avoidance, and self-stigma, and higher amounts of hope and self-directedness. Also, individuals without a comorbid personality disorder improved considerably more than comorbid patients. According to backward-stepwise multiple regression, the best significant predictor of treatment effectiveness was the initial level of self-stigma. Conclusion: The initial higher levels of self-stigma predict a lower effectiveness of treatment in resistant-anxiety-disorder patients with high comorbidity with depression and/or personality disorder. The results suggest that an increased focus on self-stigma during therapy could lead to better treatment outcomes.

Antonia Kotianova,1,2 Michal Kotian,2 Milos Slepecky,1,2 Michaela Chupacova,2 Jan Prasko,1,3 Ingrid Tonhajzerova4,51Department of Psychology Sciences, Faculty of Social Science and Health Care, Constantine the Philosopher University in Nitra, Nitra, Slovak Republic; 2Psychagogia, Garbiarska, Liptovsky Mikulas, Slovak Republic; 3Department of Psychiatry, Faculty of Medicine and Dentistry, University Palacky Olomouc, University Hospital, Olomouc, Czech Republic; 4Department of Physiology, Jessenius Faculty of Medicine in Martin, Comenius University in Bratislava, Martin, Slovak Republic; 5Biomedical Center Martin, Jessenius Faculty of Medicine in Martin, Comenius University in Bratislava, Martin, Slovak&nbsp;RepublicBackground: Alarming somatic symptoms, in particular, cardiovascular symptoms, are the characteristic feature of panic attacks. Increased cardiac mortality and morbidity have been found in these patients. Power spectral analysis of electrocardiogram R&ndash;R intervals is known to be a particularly successful tool in the detection of autonomic instabilities in various clinical disorders. Our study aimed to compare patients with panic disorder and healthy controls in heart rate variation (HRV) parameters (very-low-frequency [VLF], low-frequency [LF], and high-frequency [HF] band components of R&ndash;R interval) in baseline and during the response to the mental task.Subjects and methods: We assessed psychophysiological variables in 33 patients with panic disorder (10 men, 23 women; mean age 35.9&plusmn;10.7 years) and 33 age- and gender-matched healthy controls (10 men, 23 women; mean age 35.8&plusmn;12.1 years). Patients were treatment na&iuml;ve. Heart rate, blood pressure, muscle tension, and HRV in basal conditions and after the psychological task were assessed. Power spectrum was computed for VLF (0.003&ndash;0.04 Hz), LF (0.04&ndash;0.15 Hz), and HF (0.15&ndash;0.40 Hz) bands using fast Fourier transformation.Results: In the baseline period, the VLF band was significantly lower in panic disorder group compared to controls (p&lt;0.005). In the period of mental task, the LF/HF ratio was significantly higher in panic disorder patients compared to controls (p&lt;0.05). No significant differences were found in the remaining parameters. There was a significant difference in &Delta;HF and &Delta;LF/HF ratio between patients and controls, with &Delta; increasing in patients and decreasing in controls.Conclusion: These findings revealed that patients suffering from panic disorder were characterized by relative sympathetic dominance (reactivity) in response to mental stress compared with healthy controls.

Quality of life, self-stigma, and coping strategies in patients with neurotic spectrum disorders: a cross-sectional study

Michaela Holubova,1&ndash;3 Jan Prasko,1,2,4 Marie Ociskova,1,2 Kry&scaron;tof Kantor,1,2 Jakub Vanek,1,2 Milos&nbsp;Slepecky,4 Kristyna Vrbova1,2 1Department of Psychiatry, University Hospital Olomouc, Olomouc, Czech Republic; 2Faculty of Medicine and Dentistry, Palacky University Olomouc, Olomouc, Czech Republic; 3Department of Psychiatry, Hospital Liberec, Liberec, Czech Republic; 4Department of Psychology Sciences, Faculty of Social Science and Health Care, Constantine the Philosopher University in Nitra, Nitra, Slovakia Background: Modern psychiatry focuses on self-stigma, coping strategies, and quality of life (QoL). This study looked at relationships among severity of symptoms, self-stigma, demographics, coping strategies, and QoL in patients with neurotic spectrum disorders. Methods: A total of 153 clinically stable participants who met criteria for generalized anxiety disorder, social phobia, panic disorder, agoraphobia, mixed anxiety&ndash;depressive disorder, adjustment disorders, somatoform disorders, or obsessive&ndash;compulsive disorder were included in a cross-sectional study. Psychiatrists examined patients during regular psychiatric checkups. Patients completed the Quality of Life Satisfaction and Enjoyment Questionnaire (Q-LES-Q), Internalized Stigma of Mental Illness Scale (ISMI), a sociodemographic questionnaire, the Stress Coping Style Questionnaire (Strategie Zvl&aacute;d&aacute;n&iacute; Stresu [SVF] 78), and the Clinical Global Impression (CGI) scale. Results: The diagnostic subgroups differed significantly in age and use of negative coping strategies, but not in other measured clinical or psychological variables. The findings showed that neither sex nor partnership played a role in perceived QoL. All Q-LES-Q domains correlated negatively with all ISMI domains, except school/study. Unemployed and employed groups of patients differed in QoL. Each of the coping strategies, except the need for social support, was related to self-stigma. The findings showed that sex, partnership, education, and employment played no role in self-stigma. No differences between sexes in positive coping strategies, severity of disorder, self-stigma, or QoL were found. QoL correlated significantly with all coping strategies, except for guilt denial. Multiple regression showed the most important factors to be positive coping, employment, and overall self-stigma rating, explaining 32.9% of QoL. Mediation analysis showed self-stigma level and negative coping strategies to be the most influential. The most substantial factors associated with self-stigma, as indicated by regression analysis, were Q-LES-Q total, subjective CGI, and positive coping strategies, which clarified 44.5% of the ISMI. Conclusion: The study confirmed associations among self-stigma, quality of life, disorder severity, and coping strategies of outpatients with neurotic spectrum disorders.
