Phenomenological Study of the Lived Experiences of Appalachian Spouses of Combat Veterans with Post Traumatic Stress Disorder

Greene, Janice E 01 May 2017 (has links)
This study was conducted to identify gaps in existing knowledge regarding impacts of combat-related PTSD on the spouse and to gain an understanding of the lived experience of Appalachian Spouses of combat veterans with PTSD. A systematic literature review was conducted to identify research and findings on the impacts of combat-related PTSD on spouses of veterans and a qualitative study was conducted to gain an understanding of the lives of Appalachian spouses of combat veterans with PTSD. The systematic review identified 16 qualitative studies conducted between 1988 and 2016 in five countries spanning five wars. Regardless of the country of study or the war, the spouses experienced problems dealing with the symptoms of PTSD, emotional distress, impacts to relationships and caregiver burden. The systematic literature review revealed limited information on minority or underserved populations. Qualitative interview data from ten Appalachian spouses of combat veterans with PTSD were examined to gain an understanding of their lives. Data were obtained from semi-structured interviews. Findings indicate Appalachian Vietnam veteran spouses experience similar problems dealing with the veteran’s symptoms of PTSD, relationship problems, mental health problems and caregiver burden. The veterans in this study were not diagnosed with PTSD until later in life so they spent the majority of their life without knowledge or treatment for the illness. The women in this study expressed concerns that government and society have marginalized Vietnam veterans. This research highlights the need for outreach and PTSD education for Vietnam veterans and their spouses. Future research is recommended to expand the body of knowledge on the impacts of PTSD on the spouse with particular attention to other cultures, minority and underserved populations.

CLINICAL SOCIAL WORKERS’ PERSPECTIVES ON ILLICIT DRUG USE AND THE DEVELOPMENT OF PSYCHOTIC DISORDERS

Naseer, Asma 01 June 2017 (has links)
This purpose of this study was to explore social workers’ perspectives of drug-induced psychosis. More specifically, it sought to determine how knowledgeable clinical social workers are on the impact illicit drug use on the development of psychotic disorders. The study also aimed to discover clinical social workers’ perspectives regarding the influence of illicit drug use on the development of psychotic illnesses. This study used mixed methods approach in attempt to solve the research question. The quantitative portion of the research, an anonymous survey, allowed for the assessment of social workers’ knowledge of drug-induced psychosis. The qualitative portion of the research, individual interviews and a focus group, allowed for a comparison of social workers’ experiences from having encountered drug-induced psychosis in clinical practice. The qualitative findings produced insight that highlighted common themes that can be explored further in future research within the context of clinical social work practice.

MODELING DAILY POSTTRAUMATIC STRESS SYMPTOMS AND MENTAL CONTAMINATION EXPERIENCES AMONG SURVIVORS OF SEXUAL TRAUMA

Brake, C. Alex 01 January 2019 (has links)
Mental contamination (i.e., feelings of dirtiness in the absence of contact with a contaminant) is a potentially important yet understudied factor in posttraumatic psychopathology, particularly for survivors of sexual trauma. Mental contamination has been linked to PTSD symptom severity, negative affect, and coping cross-sectionally and in lab-based paradigms, but research has yet to assess these relationships in ecological contexts. The present study extends previous cross-sectional findings by modelling relationships between mental contamination and posttraumatic psychopathology, emotions, and coping both within-day and from one day to the next. Forty-two female sexual trauma survivors completed twice-daily assessments of mental contamination, PTSD symptoms, negative emotions, and avoidant/approach coping via a smartphone app. Daily averages and intraindividual changes in mental contamination scores were linked with PTSD symptoms at the same timepoint. Mental contamination also significantly predicted several specific avoidant coping strategies at later timepoints in addition to concurrent links. Unexpectedly, several negative emotions exhibited positive links with concurrent mental contamination but were negatively linked to later mental contamination. Exploratory analyses identified a significant interaction whereby elevated morning negative affect predicted evening reductions in mental contamination, but only for individuals also high in morning PTSD symptoms. Lastly, prevalence of reported baseline mental contamination was much higher in the present study compared to prior research. Clinical relevance and future recommendations for ecological research in trauma-related mental contamination is discussed.

INHIBITION OF TNF-ALPHA DECREASES MICROGLIA ACTIVATION IN RATS NEONATALLY TREATED WITH POLY I:C

Shelton, Heath W., Brown, Russell W. 05 April 2018 (has links)
Introduction: Current medical treatment for individuals diagnosed with schizophrenia (SCHZ) primarily relies on the inhibition of the dopamine D2 receptor that has been shown to be supersensitive in these patients. Treatment occurs through the use of antipsychotic medication which leads to a number of debilitating dose-dependent side effects, such as weight gain, agranulocytosis, and seizures. Patients diagnosed with SCHZ have also been shown to have increased inflammation in their central nervous system (CNS), particularly within specific brain regions such as the prefrontal cortex and hippocampus. This is in large part due to the interaction between a pro-inflammatory cytokine called tumor necrosis factor-alpha (TNFa) and microglia, which are resident CNS defense cells. TNFa is a cell-signaling protein, regulates a variety of immune cells, and is involved in the acute phase reaction of inflammation. Upon activation by TNFa secretion, microglial cells switch from being anti-inflammatory (M2) to pro-inflammatory (M1), thereby resulting in neuroinflammation as well as synaptic loss and neuronal death. In this project, we hypothesized oral administration through the diet of a novel TNFa modulator (PD2024) developed by P2D Biosciences, Inc. (Cincinnati, OH) would significantly reduce microglia activation in rats neonatally treated with Polyinosinic:polycytidylic acid (poly I:C). Methods and Results: To test our hypothesis, four groups (Neonatal Poly I:C/TNFa, Neonatal Poly I:C/Control, Neonatal Saline/TNFa, and Neonatal Saline/Control) were intraperitoneally injected with either poly I:C or saline during postnatal days (P)5-7. Poly I:C is an immunostimulant that mimics neonatal infection in humans, which also has been found to be a factor for the development of SCHZ later in life. Between days (P)30-(P)60, the Neonatal Poly I:C/TNFa and Neonatal Saline/TNFa groups were orally administered PD2024 through the diet. After (P)60, brain tissue was evaluated by immunohistochemistry (IHC) and confocal microscopy. Immunohistochemistry was used to label microglial cells in the prefrontal cortex and hippocampus with a green fluorescent dye attached to Iba1, a protein that specifically binds to these cells. Upon completion of IHC, tissue was evaluated using a confocal microscope and then analyzed with NIH ImageJ software. Analysis parameters included cell count, sampled cell body fluorescence, and overall image fluorescence. The results obtained showed a significant decrease in microglia activation for the Poly I:C/TNFa group when compared to the Poly I:C/Control group, as well as similarities in activation levels with the Saline/Control group. These results were demonstrated in both sampled cell body fluorescence and overall image fluorescence measurements. Conclusion: This data supports the hypothesis that PD2024 is successful in reducing microglia activation through the modulation of TNFa. Therefore, treatment with a TNFa modulator such as PD2024 alongside of current antipsychotic medication could mediate neuroinflammation and reduce the dose-dependent side effects. This approach could be a promising therapeutic treatment option for those diagnosed with schizophrenia, as well as potentially for other neurocognitive and behavioral disorders.

Tarja preta: um estudo antropológico sobre \'estados alterados\' diagnosticados pela biomedicina como transtornos mentais nos Wajãpi do Amapari / Black-Box: an anthropological study on \"altered states\" diagnosed by biomedicine as mental disorders among the Wajãpi do Amapari

Rosalen, Juliana 09 March 2018 (has links)
Esta pesquisa investiga a multiplicação dos diagnósticos de doenças mentais junto aos Wajãpi do Amapari e, concomitantemente, o aumento gradativo e discreto de prescrições de medicamentos psicotrópicos. A fim de compreender este fenômeno, são analisadas as explicações fornecidas pelas famílias acerca dos estados alterados de seus parentes, bem como os vários caminhos trilhados na tentativa de reversão dos mesmos. Nestes, as famílias estabelecem relações com os mais diversos agentes: pajés, médicos, psicólogos, missionários, pastores e curandeiros. Todas as relações abordadas nesse trabalho reforçam que, para os Wajãpi, só é possível viver realizando composições. / This research investigates the multiplication of mental illness diagnosis among the Wajãpi of Amapari and in parallel the gradual and discrete rise in prescriptions of psychotropical medications. In order to understand this phenomenon, the study analyzes both the family explanations about the altered states of their relatives and also the different paths taken to try to reverse such states. In doing so, these families establish relations with very different agents, such as: shamans, doctors, psychologists, missionaries, pastors and healers. All the relations described in this study reinforce the idea that, to Wajãpi, it is only possible to live realizing different compositions.

Applying the social cognitive and sociological models of stigma to student attitudes towards major depression and bipolar disorder

Brans, Suzanne January 2009 (has links)
The aims of the current research program were to examine the social-cognitive and sociological models of stigma in relation to student attitudes towards an individual experiencing a mood disorder. Two experiments (Studies 1 and 2) sought to empirically distinguish between controllability and responsibility, both constructs of the attribution model which is subsidiary to the social-cognitive model of stigma. Despite manipulating controllability, participants were reluctant to attribute controllability of cause to individuals experiencing depression or bipolar disorder. The stability of beliefs about the controllability of cause for condition onset was consistent with research suggesting that the Australian public increasingly conceptualise mental disorders in terms of biochemical and genetic causal factors. These findings, in combination with past research linking biogenetic beliefs to negative attitudes, resulted in a change in focus of investigation in Studies 3, 4, 5 and 6 to explain why, contrary to the prediction of the attribution model, biogenetic explanations of mental disorders are associated with the proliferation of stigma. To measure causal beliefs, the Causal Belief Inventory (CBI) was developed in Study 3 and refined in Study 4. The correlational results examined in Studies 4, 5 and 6 found that genetic and biochemical causal beliefs were associated with a number of positive attitudes towards individuals experiencing a mood disorder and that genetic cause was associated with a reduced implicit bias against major depression. Furthermore, each study pointed to the centrality of judgments of differentness in determining affective responses and direct and proxy measures of behaviour. In contrast, manipulation of genetic and psychosocial cause in Study 5 found that causal condition largely failed to impact upon student attitudes. Mediator analysis did, however, find that beliefs about the stability of the vignette actor's condition fully mediated the relationship between the negative influence of genetic cause on proxy helping behaviour. Manipulation of psychosocial, genetic and biochemical cause with the inclusion of a non-depressed control in Study 6 resulted in more ambiguous findings. The combination of findings from Studies 1 to 6 suggest that focusing on the impact of the controllability of cause of depression onset on student attitudes is unwarranted. Instead researchers and public health educators should be examining models which facilitate the examination of the cognitive factors that mediate these relationships. Two such models, namely the social-cognitive and sociological models of stigma, were found to adequately fit the data. Recommendations for integrating these two models of stigma are discussed.

The size and burden of mental disorders and other disorders of the brain in Europe 2010

Wittchen , Hans-Ulrich, Jacobi, Frank, Rehm, Jürgen, Gustavsson, Anders, Svensson, Mikael, Jönsson, Bengt, Olesen, Jes, Allgulander, Christer, Alonso, Jordi, Faravelli, Carlo, Fratiglioni, Laura, Jennum, Poul, Lieb, Roselind, Maercker, Andreas, van Os, Jim, Preisig, Martin, Salvador-Carulla, Luis, Simon, Roland, Steinhausen, Hans-Christoph 24 April 2013 (has links) (PDF)
Aims: To provide 12-month prevalence and disability burden estimates of a broad range of mental and neurological disorders in the European Union (EU) and to compare these findings to previous estimates. Referring to our previous 2005 review, improved up-to-date data for the enlarged EU on a broader range of disorders than previously covered are needed for basic, clinical and public health research and policy decisions and to inform about the estimated number of persons affected in the EU. Method: Stepwise multi-method approach, consisting of systematic literature reviews, reanalyses of existing data sets, national surveys and expert consultations. Studies and data from all member states of the European Union (EU-27) plus Switzerland, Iceland and Norway were included. Supplementary information about neurological disorders is provided, although methodological constraints prohibited the derivation of overall prevalence estimates for mental and neurological disorders. Disease burden was measured by disability adjusted life years (DALY). Results: Prevalence: It is estimated that each year 38.2% of the EU population suffers from a mental disorder. Adjusted for age and comorbidity, this corresponds to 164.8 million persons affected. Compared to 2005 (27.4%) this higher estimate is entirely due to the inclusion of 14 new disorders also covering childhood/adolescence as well as the elderly. The estimated higher number of persons affected (2011: 165 m vs. 2005: 82 m) is due to coverage of childhood and old age populations, new disorders and of new EU membership states. The most frequent disorders are anxiety disorders (14.0%), insomnia (7.0%), major depression (6.9%), somatoform (6.3%), alcohol and drug dependence (> 4%), ADHD (5%) in the young, and dementia (1–30%, depending on age). Except for substance use disorders and mental retardation, there were no substantial cultural or country variations. Although many sources, including national health insurance programs, reveal increases in sick leave, early retirement and treatment rates due to mental disorders, rates in the community have not increased with a few exceptions (i.e. dementia). There were also no consistent indications of improvements with regard to low treatment rates, delayed treatment provision and grossly inadequate treatment. Disability: Disorders of the brain and mental disorders in particular, contribute 26.6% of the total all cause burden, thus a greater proportion as compared to other regions of the world. The rank order of the most disabling diseases differs markedly by gender and age group; overall, the four most disabling single conditions were: depression, dementias, alcohol use disorders and stroke. Conclusion: In every year over a third of the total EU population suffers from mental disorders. The true size of “disorders of the brain” including neurological disorders is even considerably larger. Disorders of the brain are the largest contributor to the all cause morbidity burden as measured by DALY in the EU. No indications for increasing overall rates of mental disorders were found nor of improved care and treatment since 2005; less than one third of all cases receive any treatment, suggesting a considerable level of unmet needs. We conclude that the true size and burden of disorders of the brain in the EU was significantly underestimated in the past. Concerted priority action is needed at all levels, including substantially increased funding for basic, clinical and public health research in order to identify better strategies for improved prevention and treatment for disorders of the brain as the core health challenge of the 21st century.

Cost of disorders of the brain in Europe 2010

Gustavsson, Anders, Svensson, Mikael, Jacobi, Frank, Allgulander, Christer, Alonso, Jordi, Beghi , Ettore, Dodel, Richard, Ekman, Mattias, Faravelli, Carlo, Fratiglioni, Laura, Gannon, Brenda, Jones, David Hilton, Jennum, Poul, Jordanova, Albena, Jönsson, Linus, Karampampa, Korinna, Knapp, Martin, Kobelt, Gisela, Kurth, Tobias, Lieb, Roselind, Linde, Mattias, Ljungcrantz, Christina, Maercker, Andreas, Melin, Beatrice, Moscarelli, Massimo, Musayev, Amir, Norwood, Fiona, Preisig, Martin, Pugliatti, Maura, Rehm, Juergen, Salvador-Carulla, Luis, Schlehofer, Brigitte, Simon, Roland, Steinhausen, Hans-Christoph, Stovner, Lars Jacob, Vallat, Jean-Michel, Van den Bergh, Peter, van Os, Jim, Vos, Pieter, Xu, Weili, Wittchen, Hans-Ulrich, Jönsson, Bengt, Olesen, Jes 24 April 2013 (has links) (PDF)
Background: The spectrum of disorders of the brain is large, covering hundreds of disorders that are listed in either the mental or neurological disorder chapters of the established international diagnostic classification systems. These disorders have a high prevalence as well as short- and long-term impairments and disabilities. Therefore they are an emotional, financial and social burden to the patients, their families and their social network. In a 2005 landmark study, we estimated for the first time the annual cost of 12 major groups of disorders of the brain in Europe and gave a conservative estimate of €386 billion for the year 2004. This estimate was limited in scope and conservative due to the lack of sufficiently comprehensive epidemiological and/or economic data on several important diagnostic groups. We are now in a position to substantially improve and revise the 2004 estimates. In the present report we cover 19 major groups of disorders, 7 more than previously, of an increased range of age groups and more cost items. We therefore present much improved cost estimates. Our revised estimates also now include the new EU member states, and hence a population of 514 million people. Aims: To estimate the number of persons with defined disorders of the brain in Europe in 2010, the total cost per person related to each disease in terms of direct and indirect costs, and an estimate of the total cost per disorder and country. Methods: The best available estimates of the prevalence and cost per person for 19 groups of disorders of the brain (covering well over 100 specific disorders) were identified via a systematic review of the published literature. Together with the twelve disorders included in 2004, the following range of mental and neurologic groups of disorders is covered: addictive disorders, affective disorders, anxiety disorders, brain tumor, childhood and adolescent disorders (developmental disorders), dementia, eating disorders, epilepsy, mental retardation, migraine, multiple sclerosis, neuromuscular disorders, Parkinson's disease, personality disorders, psychotic disorders, sleep disorders, somatoform disorders, stroke, and traumatic brain injury. Epidemiologic panels were charged to complete the literature review for each disorder in order to estimate the 12-month prevalence, and health economic panels were charged to estimate best cost-estimates. A cost model was developed to combine the epidemiologic and economic data and estimate the total cost of each disorder in each of 30 European countries (EU27 + Iceland, Norway and Switzerland). The cost model was populated with national statistics from Eurostat to adjust all costs to 2010 values, converting all local currencies to Euro, imputing costs for countries where no data were available, and aggregating country estimates to purchasing power parity adjusted estimates for the total cost of disorders of the brain in Europe 2010. Results: The total cost of disorders of the brain was estimated at €798 billion in 2010. Direct costs constitute the majority of costs (37% direct healthcare costs and 23% direct non-medical costs) whereas the remaining 40% were indirect costs associated with patients' production losses. On average, the estimated cost per person with a disorder of the brain in Europe ranged between €285 for headache and €30,000 for neuromuscular disorders. The European per capita cost of disorders of the brain was €1550 on average but varied by country. The cost (in billion €PPP 2010) of the disorders of the brain included in this study was as follows: addiction: €65.7; anxiety disorders: €74.4; brain tumor: €5.2; child/adolescent disorders: €21.3; dementia: €105.2; eating disorders: €0.8; epilepsy: €13.8; headache: €43.5; mental retardation: €43.3; mood disorders: €113.4; multiple sclerosis: €14.6; neuromuscular disorders: €7.7; Parkinson's disease: €13.9; personality disorders: €27.3; psychotic disorders: €93.9; sleep disorders: €35.4; somatoform disorder: €21.2; stroke: €64.1; traumatic brain injury: €33.0. It should be noted that the revised estimate of those disorders included in the previous 2004 report constituted €477 billion, by and large confirming our previous study results after considering the inflation and population increase since 2004. Further, our results were consistent with administrative data on the health care expenditure in Europe, and comparable to previous studies on the cost of specific disorders in Europe. Our estimates were lower than comparable estimates from the US. Discussion: This study was based on the best currently available data in Europe and our model enabled extrapolation to countries where no data could be found. Still, the scarcity of data is an important source of uncertainty in our estimates and may imply over- or underestimations in some disorders and countries. Even though this review included many disorders, diagnoses, age groups and cost items that were omitted in 2004, there are still remaining disorders that could not be included due to limitations in the available data. We therefore consider our estimate of the total cost of the disorders of the brain in Europe to be conservative. In terms of the health economic burden outlined in this report, disorders of the brain likely constitute the number one economic challenge for European health care, now and in the future. Data presented in this report should be considered by all stakeholder groups, including policy makers, industry and patient advocacy groups, to reconsider the current science, research and public health agenda and define a coordinated plan of action of various levels to address the associated challenges. Recommendations: Political action is required in light of the present high cost of disorders of the brain. Funding of brain research must be increased; care for patients with brain disorders as well as teaching at medical schools and other health related educations must be quantitatively and qualitatively improved, including psychological treatments. The current move of the pharmaceutical industry away from brain related indications must be halted and reversed. Continued research into the cost of the many disorders not included in the present study is warranted. It is essential that not only the EU but also the national governments forcefully support these initiatives.

Increased 12-Month Prevalence Rates of Mental Disorders in Patients with Chronic Somatic Diseases

Härter, Martin, Baumeister, Harald, Reuter, Katrin, Jacobi, Frank, Höfler, Michael, Bengel, Jürgen, Wittchen, Hans-Ulrich 22 November 2012 (has links) (PDF)
Background: Although it is well established that chronic somatic diseases are significantly associated with a wide range of psychopathology, it remains unclear to what extent subjects with chronic somatic diseases are at increased risk of experiencing mental disorders. The present epidemiological study investigates age- and sex-adjusted 12-month prevalence rates of mental disorders in patients with cancer, and musculoskeletal, cardiovascular and respiratory tract diseases, based on comprehensive physicians’ diagnoses and compared with physically healthy probands. Methods: Prevalence rates were calculated from two large epidemiological surveys. These studies investigated inpatients and patients from the general population with cancer (n = 174) and musculoskeletal (n = 1,416), cardiovascular (n = 915) and respiratory tract diseases (n = 453) as well as healthy controls (n = 1,083). The prevalence rates were based on the Munich Composite International Diagnostic Interview, a standardized interview for the assessment of mental disorders. Results: Prevalence rates were very similar for inpatients (43.7%) and patients from the general population (42.2%). The adjusted odds ratios (OR) of patients with chronic somatic diseases were significantly elevated for mental disorders in comparison with healthy probands (OR: 2.2). Mood, anxiety and somatoform disorders were most frequent. The prevalence rates did not differ significantly between the somatic index diseases. The number of somatic diseases per patient had a higher association with mental disorders. Conclusions: There is a strong relationship between chronic somatic diseases and mental disorders. A future task is to improve the care of mental disorders in patients with chronic physical illness, specifically with multimorbid conditions.

Wie häufig sind Substanzmißbrauch und -abhängigkeit? / How frequent are substance abuse and dependences? A critical review

Perkonigg, Axel, Wittchen, Hans-Ulrich, Lachner, Gabriele 23 October 2012 (has links) (PDF)
Die Arbeit gibt einen methodenkritischen Überblick über die in Deutschland vorliegenden Ergebnisse zur Prävalenz sowie Risikofaktoren von Substanzmißbrauch und -abhängigkeit (SMA). Es wird gezeigt, daß die vorliegenden epidemiologischen Studien unvollständig und methodisch unbefriedigend sind. Vor allem die fehlende Erfassung spezifischer diagnostischer Kriterien zur Ableitung klinisch relevanter Mißbrauchs- und Abhängigkeitsstörungen erschwert eine Interpretation der Ergebnisse der vorliegenden Repräsentativerhebungen. Diese geben zwar aussagekräftige populationsbezogene Informationen über die Häufigkeit und Verteilungsmuster von legalen und illegalen Substanzen, klinisch relevante Beurteilungsaspekte wie z.B. zu Schweregrad, Toleranz und Abstinenzproblemen sowie zu Einstieg und Verlauf der "Sucht"-Problematik fehlen jedoch vollständig. Dies trifft auch für Untersuchungen zu Risikofaktoren zu. Als ein durchgängiger Mangel wird ferner die Erfassungsmethodologie angesehen, die sich bislang fast ausschließlich auf Fragebögen oder Interviews stützt, über deren Reliabilität und Validität nur unzureichende psychometrische Daten vorliegen. / A critical review of prevalence and risk factor studies of substance abuse and dependence in Germany is presented. It is shown that currently available epidemiological data are incomplete due to the failure of instruments to allow for a detailed assessment of specific substance use disorders. The neglect of diagnostic criteria for clinically significant abuse and dependence disorders makes it especially difficult to draw conclusions about the results of representative surveys. Although the give clear population-related information about frequency and distribution patterns of legal and illegal substancees, relevant clinical data regarding aspects such as severity, tolerance, problems of abstinence, onset and course of abuse and dependence are completely lacking. This is also true of studies on risk factors. An additional problem is diagnostic assessment based almost exclusively on questionnaires and interviews whose reliability and validity have not been sufficiently established.
