Research Paper On Post Traumatic Stress Disorder

These signs mirror the spectrum of psychobiological symptoms in PTSD. These manifestations are generally associated with the nature of the stress, its duration, chronicity and severity. A group of symptoms, now referred to as the sickness behavior, is also noted that is associated with clinically relevant changes in the balance between the psychoneuroendocrine and the immune systems 35 — By the early s, Walter Cannon — proposed that organisms engage in a dynamic process of adjustment of the physiological balance of the internal milieu in response to changing environmental conditions.

Stress alters the regulation of both the sympathetic and the parasympathetic branches of the autonomic nervous system, with consequential alterations in hypothalamic control of the endocrine response controlled by the pituitary gland. Autonomic activation and the elevation of hormones, including those produced by the hypothalamic-pituitary-adrenal axis, play a pivotal role in regulating cell-mediated immune surveillance mechanisms, including the production of cytokines that control inflammatory and healing events 35 , In brief, the perception of stress leads to a significant load upon physiological regulation, including circadian regulation, sleep and psychoneuroendocrine-immune interaction.

In brief, stress is profound alterations in the cross-regulation and interaction of the hormonal-immune regulatory axis. The experience of stress, as well as that of traumatic events and the anxiety-laden recollections thereof, produce a primary endocrine response, which involves the release of glucocorticoids GCs. GCs regulate cellular immune activity in vivo systemically and locally. They block the production of pro-inflammatory cytokines e. IL-2 at the molecular level in vitro and in vivo , but may have little effects upon TH2 cytokines e. The net effect of challenging immune cells with GC is to impair immune T cell activation and proliferation, while maintaining antibody production.

The secretion of GC by the adrenal cortex is under the control of the anterior pituitary adrenocorticotropin hormone ACTH.

Immune challenges release pro-inflammatory cytokines e. Stressful stimuli also lead to the significant activation of the sympathetic nervous system and a rise in the levels of pro-inflammatory cytokines i. It follows that the consequences of stress are not uniform. The psychopathological and the physiopathological impacts of stress may be significantly greater in certain people, compared with those of others. The impact of stress is dynamic and multifaceted and the same person may exhibit a variety of manifestations of the psychoneuroendocrine-immune stress response with varying degrees of severity at different times.

The outcome of stress can be multivalent Allostatic regulation now signifies the recovery and the maintenance of internal balance and viability amidst changing circumstances consequential to stress. It encompasses a range of behavioral and physiological functions that direct the adaptive function of regulating homeostatic systems in response to challenges 37 — The cumulative load of the allostatic process is the allostatic load.

The pathological side effects of failed adaptation are the allostatic overload.

Allostasis pertains to the psychobiological regulatory system with variable set points. These set points are characterized by individual differences. They are associated with anticipatory behavioral and physiological responses and are vulnerable to physiological overload and breakdown of regulatory capacities 39 , Type 1 allostatic load utilizes, as it were, stress responses as a means of self-preservation by developing and establishing temporary or permanent adaptation skills.

The organism aims at surviving the perturbation in the best condition possible and at normalizing the normal life cycle. In Type 2 allostatic load, the stressful challenge is excessive, sustained or continued and drives allostasis chronically.

An escape response cannot be found. Type I versus type II allostatic responses curiously reiterate Myers' observations that his patients seem to abandon themselves to the emotion and the fear that assailed them, rather than engage in the effort to counter and to overcome the challenge, which normal subjects typically undertook.

Future research in PTSD from the perspective of allostasis may reveal a learned helplessness component, which could become key in the development and evaluation of treatment interventions Fig. Allostatic regulation describes the recovery and the maintenance of internal balance and viability amidst changing circumstances consequential to stress. It encompasses the Type 1 allostatic load that reflects the utilization by the organism of the range of behavioral and physiological functions that direct the adaptive function of regulating homeostatic systems in response to challenges i. Type 1 allostatic responses translate the organism aims at surviving the perturbation in the best condition possible and at normalizing the normal life cycle.

By contrast, the Type 2 allostatic responses reflect a load to the organism that is excessive, sustained, or continued, and drives allostasis chronically and that precludes effective escape from the stress. It is clear that stress research and PTSD research are intertwined. Psychobiological manifestations in PTSD and in complex PTSD disorder of extreme stress evidently pertain to the same domain of mind—body interactions, which are elucidated in psychoneuroimmunology research. The stress response, more than likely, underlies the psychobiological sequelae of PTSD.

The relevance of the field of current research on allostasis to PTSD is all the more evident when one considers that subjects position themselves along a spectrum of allostatic regulation, somewhere between allostasis i. In brief, the recent advances in our understanding of the adaptation of the organism to stressful challenges, the allostatic process, present a new and a rich paradigm for research in the psychobiology of PTSD. Future research must investigate whether or not the dichotomy of Type I and Type II allostatic responses will provide an effective theoretical model for the development of novel and improved modes of intervention to treat PTSD.

The treatment of PTSD is complex, both in terms of available treatments and the myriad of trauma possibilities that cause it.

This should be followed by treatments with various degrees of demonstrated efficacy Historically, it was in the early eighties when research on the treatment efficacy for PTSD began, with multitude of case studies dealing with different kinds of PTSD having been produced since then. Overall, both cognitive behavioral approaches and selective serotonin reuptake inhibitor regimes have been proved to be effective to deal with different kinds of PTSD. At the same time, there is also evidence that other treatment modalities, such as psychodynamic psychotherapy, hypnotherapy, eye movement desensitization and reprocessing can be effective as well; albeit their evidence is derived from less numerous and less well-controlled studies i.

PTSD intervention is complicated further by the fact that co-morbidities e. Particularly in situations where co-morbidity exists, a combined approached should be considered. Of interest due to the perilous state of the world i. According to experts, combat veterans with PTSD may be less responsive to treatment that other victims of other traumatic exposures 41 , Following is a list of possible reasons:.

Combat-caused PTSD is often associated with other psychiatric disorders, including depression, anxiety, mood disorders and substance abuse disorders It is usually believed that the most effective treatment results are obtained when both PTSD and the other disorder s are treated together rather than one after the other. It is becoming increasingly critical to ascertain this position because the prevalence of PTSD and disorder of complex stress is bound to rise sharply in the next decade consequential to the present multinational state of alert and anxiety following ongoing tragic, wanton and widespread terrorism and particularly with respect to combat-related PTSD in present times.

Some have more proven efficacy than others. Some of these approaches may be appropriate to address the initial stages of trauma. Psychological debriefing is an intervention given shortly after the occurrence of a traumatic event. The goal is to prevent the subsequent development of negative psychological effects.

In fact, psychological debriefing approaches to PTSD can be described as semi-structured interventions aimed at reducing initial psychological stress. Strategies include emotional processing via catharsis, normalization and preparation for future contingencies Gulf War veterans who underwent psychological debriefing showed no significant differences in their scores of two scales measuring PTSD when compared with the control group In general, there is little evidence of psychological debriefing approaches effectively acting to prevent psychopathology, although participants seem to be open to it, which may indicate its usefulness as a rapport builder or as a screening tool.

In general however, there is a lack of rigorously conducted research in this area. To this day there is paucity in the data to orient the treatment of combat-related PTSD for veterans The International Consensus Group on Depression and Anxiety supports that exposure psychotherapy is the most appropriate approach for this disorder 41 , although this approach does not show a significant influence on PTSD's negative symptomatology, such as avoidance, impaired relationships or anger control In terms of proven efficacy, cognitive behavior therapy and eye movement desensitization and reprocessing are effective approaches to deal with PTSD 50 — 54 , while other psychotherapeutic approaches e.

Cognitive-behavioral psychotherapy encompasses a myriad of approaches i. Vietnam veterans receiving exposure therapy displayed improvement as evidenced in terms of reducing intrusive combat memories 55 , physiological responding, anxiety 56 , depression and feelings of alienation, while also promoting increased vigor and skills confidence Exposure therapy, combined with a standard treatment also showed effectiveness with other Vietnam veterans in terms of subject self-report symptoms related to the traumatic experiences, sleep and subjective anxiety responding to trauma stimuli In fact, typically, there is a combination of psychotherapy and medication treatments to treat chronic PTSD In general, the different co-morbidities associated with PTSD play a role in the kinds of pharmacotherapeutic treatments used for its treatment.

Antidepressants and other medications commonly used are tricyclic antidepressants, monoamine oxidase inhibitors, selective serotonin reuptake inhibitors, antianxiety and adrenergic agents and mood stabilizers Sertraline has been found effective to reduce PTSD symptomatology 61 , Sertraline and fluoxetine have produced clinical improvements among PTSD patients in randomized clinical trials Paroxetine, another selective serotonin reuptake inhibitor like sertraline, is also habitually used to treat chronic PTSD Mirtazapine was another successful agent when used in the treatment of PTSD afflicted Korean veterans In addition, Olanzapine and fluphenazine have been successfully used with combat-induced PTSD subjects from the Balkans.

Both medicines were successful in ameliorating both PTSD and psychotic symptomatology Rigorous, well-controlled methods are necessary for conducting studies on the efficacy of PTSD treatments. Well-controlled studies are characterized by the following characteristics:. Future clinical research in PTSD requires the stringent, rigorous and systematic approach provided by evidence-based medicine.

Research Topics

Evidence-based research in medicine goes beyond the routine narrative literature review. It systematically evaluates the strength of the available evidence and generates a consensus statement of the best available evidence in the form of a systematic review of the available research Fig. What are the interventions being looked at, e.

Are the interventions being compared or are predictions being drawn, i. What is the outcome of interest, e. The second step involves methodology, including the sampling of the research literature, and the tools for the critical analysis of the reports. The fourth step is concerned with the analysis of the data gathered in the evidence-based research process.

This commonly entails meta-analytical and meta-regression techniques, as well as individual patient data analysis e. Depending upon the tools utilized to evaluate the scientific literature, scores about the completeness and quality of research methodology, design and statistical handling of the findings are generated SESTA, systematic evaluation of the statistical analysis.

These values are analyzed by acceptable sampling statistical protocols to establish whether or not the sample of research reports studied by means of the evidence-based process was statistically acceptable to produce reliable inferences. The last step is a cumulative synthesis, which summarizes the process and the findings.
