Abstract
Post-traumatic stress disorder (PTSD), currently included by the Diagnostic and Statistical of Mental Disorders, Fifth Edition, Text Revision in the macro-category "disorders related to traumatic and stressful events", is a severe mental distress that arises acutely as a result of direct or indirect exposure to severely stressful and traumatic events. A large body of literature is available on the psychological and behavioral manifestations of PTSD; however, with regard to the more purely neuropsychological aspects of the disorder, they are still the subject of research and need greater clarity, although the roles of the thalamus, hypothalamus, amygdala, cingulate gyrus, cerebellum, locus coeruleus, and hippocampus in the onset of the disorder's characteristic symptoms have already been elucidated.

Abstract
Humans have lived in a dynamic environment fraught with potential dangers for thousands of years. While fear and stress were crucial for the survival of our ancestors, today, they are mostly considered harmful factors, threatening both our physical and mental health. Trauma is a highly stressful, often life-threatening event or a series of events, such as sexual assault, war, natural disasters, burns, and car accidents. Trauma can cause pathological metaplasticity, leading to long-lasting behavioral changes and impairing an individual's ability to cope with future challenges. If an individual is vulnerable, a tremendously traumatic event may result in post-traumatic stress disorder (PTSD). The hypothalamus is critical in initiating hormonal responses to stressful stimuli via the hypothalamic-pituitary-adrenal (HPA) axis. Linked to the prefrontal cortex and limbic structures, especially the amygdala and hippocampus, the hypothalamus acts as a central hub, integrating physiological aspects of the stress response. Consequently, the hypothalamic functions have been attributed to the pathophysiology of PTSD. However, apart from the well-known role of the HPA axis, the hypothalamus may also play different roles in the development of PTSD through other pathways, including the hypothalamic-pituitary-thyroid (HPT) and hypothalamic-pituitary-gonadal (HPG) axes, as well as by secreting growth hormone, prolactin, dopamine, and oxytocin. This review aims to summarize the current evidence regarding the neuroendocrine functions of the hypothalamus, which are correlated with the development of PTSD. A better understanding of the role of the hypothalamus in PTSD could help develop better treatments for this debilitating condition.

Abstract
BACKGROUND Abnormal thyroid function is prevalent among women and has been linked to increased risk of chronic disease. Posttraumatic stress disorder (PTSD) has been linked to thyroid dysfunction in some studies; however, the results have been inconsistent. Thus, we evaluated trauma exposure and PTSD symptoms in relation to incident thyroid dysfunction in a large longitudinal cohort of civilian women. METHODS We used data from 45 992 women from the ongoing Nurses' Health Study II, a longitudinal US cohort study that began in 1989. In 2008, history of trauma and PTSD were assessed with the Short Screening Scale for Diagnostic and Statistical Manual of Mental Disorders, fourth edition, PTSD, and incident thyroid dysfunction was determined by participants' self-report in biennial questionnaires of physician-diagnosed hypothyroidism and Graves' hyperthyroidism. The study period was from 1989 to 2013. Proportional hazard models were used to estimate multivariable-adjusted hazard ratios and 95% confidence intervals (CIs) for incident hypothyroidism and Graves' hyperthyroidism. RESULTS In multivariable-adjusted models, we found significant associations for PTSD only with hypothyroidism [p-trend <0.001; trauma with no PTSD symptoms, 1.08 (95% CI 1.02-1.15); 1-3 PTSD symptoms, 1.12 (95% CI 1.04-1.21); 4-5 PTSD symptoms, 1.23 (95% CI 1.13-1.34); and 6-7 PTSD symptoms, 1.26 (95% CI 1.14-1.40)]. PTSD was not associated with risk of Graves' hyperthyroidism (p-trend = 0.34). Associations were similar in sensitivity analyses restricted to outcomes with onset after 2008, when PTSD was assessed. CONCLUSIONS PTSD was associated with higher risk of hypothyroidism in a dose-dependent fashion. Highlighted awareness for thyroid dysfunction may be especially important in women with PTSD.

Abstract
The objective of this study was to investigate the relationship between serum lipid concentrations and PTSD symptoms in the bereaved after a traumatic familial loss. Eighteen months after the Sewol ferry disaster, 107 subjects who experienced traumatic losses as a result of the accident completed a mental and medical survey as well as laboratory tests for lipid profiles. At 30 months after the trauma, a total of 64 individuals completed a follow-up psychometric survey and biochemical measurements. We performed multiple linear regression analyses, examining the association between PTSD symptoms and lipid profiles. Other potential influences on lipid profiles such as metabolic risk factors, demographic risk factors, and underlying medical history were accounted for. Participants reporting clinically significant PTSD symptoms exhibited lower serum HDL-C levels than those without PTSD symptoms. In addition, we found that the severity of PTSD symptoms and sex could explain the changes in lipid profiles independently of other possible risk factors of changes. The results of this study suggest that PTSD symptoms may contribute to an increased risk for developing metabolic syndrome via detrimental changes in lipid concentrations. Routine screening and multidisciplinary management to prevent metabolic syndrome in individuals who experience traumatic losses would therefore be valuable.

Abstract
The hypothalamus-pituitary-thyroid feedback control is a dynamic, adaptive system. In situations of illness and deprivation of energy representing type 1 allostasis, the stress response operates to alter both its set point and peripheral transfer parameters. In contrast, type 2 allostatic load, typically effective in psychosocial stress, pregnancy, metabolic syndrome, and adaptation to cold, produces a nearly opposite phenotype of predictive plasticity. The non-thyroidal illness syndrome (NTIS) or thyroid allostasis in critical illness, tumors, uremia, and starvation (TACITUS), commonly observed in hospitalized patients, displays a historically well-studied pattern of allostatic thyroid response. This is characterized by decreased total and free thyroid hormone concentrations and varying levels of thyroid-stimulating hormone (TSH) ranging from decreased (in severe cases) to normal or even elevated (mainly in the recovery phase) TSH concentrations. An acute versus chronic stage (wasting syndrome) of TACITUS can be discerned. The two types differ in molecular mechanisms and prognosis. The acute adaptation of thyroid hormone metabolism to critical illness may prove beneficial to the organism, whereas the far more complex molecular alterations associated with chronic illness frequently lead to allostatic overload. The latter is associated with poor outcome, independently of the underlying disease. Adaptive responses of thyroid homeostasis extend to alterations in thyroid hormone concentrations during fetal life, periods of weight gain or loss, thermoregulation, physical exercise, and psychiatric diseases. The various forms of thyroid allostasis pose serious problems in differential diagnosis of thyroid disease. This review article provides an overview of physiological mechanisms as well as major diagnostic and therapeutic implications of thyroid allostasis under a variety of developmental and straining conditions.

Abstract
Post-traumatic stress disorder (PTSD) is a serious psychiatric consequence of trauma that occurs in a proportion of individuals exposed to life-threatening events. Trauma-focused psychotherapy is often recommended as first choice for those who do not recover spontaneously. But many individuals require medications. In the US, only paroxetine (PRX) and sertraline (SRT) are FDA approved for PTSD. But response and remission rates with these medications are low, so numerous other pharmacologic interventions have been tried. To date, there has not been a systematic review of the data on what are the best next-step pharmacologic strategies for individuals who fail standard treatments. To that end, we review 168 published trials of medications other than PRX or SRT and provide a detailed analysis of the 88/168 studies that describe alternative pharmacologic interventions in patients refractory to other treatment. We also review clinical factors relevant to treatment-refractory PTSD; the neurobiology of extinction, as well as evidence-based psychotherapy and neuromodulation strategies for this condition.

Abstract
Posttraumatic stress disorder (PTSD) and depressive symptoms have been theorized to mediate the relationship between trauma exposure and physical health symptoms. Although empirical evidence supports this premise, studies conducted to date have employed statistical mediation analyses that are now broadly criticized. Furthermore, the mediating roles of both PTSD and depressive symptoms have seldom been examined concurrently, and it remains unclear which PTSD symptom clusters uniquely mediate this relationship. The aim of the present study was to examine the mediating role of reexperiencing, avoidance/numbing, hyperarousal, and depressive symptoms in the relationship between trauma exposure and physical health symptoms. Participants were 516 Spanish female undergraduate students. Physical health symptoms were compared between those who reported trauma exposure (n = 266) and those who did not (n = 250). Data from trauma-exposed participants were analyzed using regression models with bootstrapping to test mediation. Results of the analyses showed that the trauma-exposed group reported significantly more physical health symptoms (r(2) = .035). Hyperarousal and depressive symptoms uniquely mediated the relationship between trauma exposure and physical health symptoms. Our findings clarify some of the mechanisms by which negative health consequences occur subsequent to trauma exposure.

Abstract
INTRODUCTION We previously reported a unique hypothalamic-pituitary-thyroid (HPT) axis profile in women with a menstrually related mood disorder (MRMD) who also had a history of sexual abuse (SA). In the present study, we sought to extend that work by examining the association of an SA history with HPT-axis disturbance in both women with MRMD and women without MRMD. METHODS Fifty-seven women met the prospective criteria for MRMD (23 with an SA history), and 52 women were non-MRMD (18 with an SA history). Thyroid-stimulating hormone, thyroxin (T4; total and free), and triiodothyronine (T3; total and free) were evaluated in serum, together with thyroid hormone ratios reflecting T4 to T3 conversion. RESULTS Women with MRMD, compared with women without MRMD, had elevated T3/T4 ratios (p values ≤ .01; reflecting increased conversion of T4 to T3) and lower free and total T4 concentrations (p values = .01). Higher T3/T4 ratios and lower T4 concentrations predicted more severe premenstrual symptoms in all women. An SA history, irrespective of MRMD status, was associated with elevated thyroid-stimulating hormone concentrations (p = .03). However, in women with MRMD, an SA history was associated with elevated T3 concentrations (p = .049), whereas in women without MRMD, an SA history was associated with decreased T3 concentrations (p = .02). CONCLUSIONS An MRMD and an SA history are associated with independent and interactive effects on the HPT axis. The evidence that an MRMD moderates the influence of SA on T3 concentrations contributes to a growing body of work suggesting that an SA history may identify a distinct subgroup of women with MRMD.

Abstract
Post-traumatic stress disorder (PTSD) is a chronic, debilitating psychiatric disorder that can follow exposure to extreme stressful experiences. It is characterised by hyperarousal and increased startle responses, re-experiencing of the traumatic event, withdrawal or avoidance behaviour and emotional numbing. The focus of this review is on aspects that have received less attention. PTSD develops only in a substantial minority of people exposed to traumatic stress, and possible individual traits that increase vulnerability are discussed. An overview is given of the wide variety of physiological disturbances that accompany PTSD and may contribute to disability, including neuroendocrine, cardiovascular, gastrointestinal and immune function and pain sensitivity. Brain imaging and pharmacological studies have generated some insight into the circuitry that may be involved in the generation of PTSD symptoms. Major limitations of human studies so far are the issue of causality and our lack of understanding of the underlying molecular substrates in the brain, which are easier to address in relevant animal models and will be discussed in a companion paper.

Abstract
OBJECTIVE To explore the relationships between psychological symptoms and thyroid hormone levels in adolescent girls who had experienced the traumatic stress of sexual abuse. METHOD The study design was cross-sectional/correlational. Subjects (N=22; age range=12-18 years) had their blood drawn, and they completed 2 psychological tests (depression and general distress/posttraumatic stress disorder [PTSD]). A pediatrician completed a sexual abuse questionnaire after reviewing law enforcement and Child Protective Services reports and conducting forensic interviews and medical examinations. RESULTS Girls' average free T4, total T4, free T3, total T3, and TSH levels were within age-specific laboratory reference range limits, as were most individual concentrations. The strongest correlations (p<.05) were between free T3 and PTSD total score (-.50), PTSD-avoidance/numbing (-.49), and general distress (-.48); and between total T3 and depression (-.46), general distress (-.45), and PTSD-arousal (-.44). CONCLUSIONS Our findings support one of the two contemporary models of the relationships between thyroid hormones (i.e., free and total T3) and psychological symptoms (i.e., depression, general distress, and PTSD)--one of "shutting down" (vs. "activation") in the face of trauma.

Abstract
BACKGROUND Research on thyroid activity among male combat veterans with posttraumatic stress disorder (PTSD) has consistently shown elevations in total triiodothyronine (TT3) and inconsistent elevations of other thyroid variables. This study is the first large scale investigation of thyroid function in women with PTSD. METHODS Thyroid function was measured in 63 women with PTSD due to childhood sexual abuse (PTSD-CSA) in comparison with a community sample of 42 women without current PTSD-CSA. Clinical measures included the Clinician Administered PTSD Scale (CAPS), the Evaluation of Lifetime Stressors, the Trauma Assessment for Adults and the Beck Depression Inventory. RESULTS Women with PTSD-CSA showed significant elevations in Total T3 and the TT3/free thyroxine (TT3/FT4) ratio, the FT3/TT3 ratio, and modest reductions in thyroid stimulating hormone relative to our community sample. These findings could not be explained by the influence of prior trauma, lifetime PTSD or depressive symptoms. CONCLUSIONS Altered thyroid activity, especially elevated Total T3 levels, was found in women with PTSD associated with childhood sexual abuse.

Abstract
BACKGROUND Post-traumatic stress disorder (PTSD) is a relatively new psychiatric disorder with three clusters of symptoms: trauma re-experiencing, avoidance, and increased arousal. The condition develops after a person sees, is involved in, or hears of an extreme traumatic stressor such as war, torture, natural catastrophe, assault, rape, or serious accident. PTSD is also often comorbid with other psychiatric disorders, especially with alcohol dependence. Several hormonal alterations have been reported in veterans with combat-related PTSD, including elevations in certain thyroid hormones, e.g., total T3; however, previous studies have not controlled for alcohol dependence, a common comorbid psychiatric disorder in this population. OBJECTIVE The first aim of our study was to assess possible differences in basal serum levels of free triiodothyronine (FT3), total triiodothyronine (TT3), free thyroxine (FT4), total thyroxine (TT4), and thyroid stimulating hormone (TSH) in Croatian soldiers with combat-related chronic PTSD alone or comorbid with alcohol dependence and in healthy controls. The second purpose of the study was to determine any correlation between duration of combat activities, number of combat traumas, intensity and duration of PTSD symptoms, and serum levels of TT3, FT3, TT4, FT4, and TSH in this sample. METHOD We analyzed basal serum FT3, TT3, FT4, TT4, and TSH concentrations in soldiers with combat-related chronic PTSD (N=43), combat-related chronic PTSD comorbid with alcohol dependence (N = 41), and in healthy controls (N = 39) using a luminoimmunochemical assay. RESULTS Soldiers with chronic combat-related PTSD with or without comorbid alcohol addiction had significantly higher values of TT3 than the control group (F = 19.556, p<0.01). There was a significant correlation between TT3 levels and number of traumatic events in both the PTSD group (r=0.663, p<0.01) and those with PTSD comorbid with alcohol dependence (r=0.836, p<0.01). There was also a significant correlation between TT3 levels and symptoms of increased arousal in both PTSD (r=0.419, p<0.01) and PTSD comorbid with alcohol dependence (r=0.516, p<0.01). CONCLUSION Elevated concentrations of serum TT3 are associated with combat-related PTSD, regardless of its comorbidity with alcohol dependence, and also with the number of traumatic events and symptoms of increased arousal. Given that current pharmacotherapy for PTSD is inadequate, reduction of TT3 may be a new strategy for pharmacologic intervention that could contribute to more effective treatment of this disorder.

Abstract
This study is a follow-up investigation of a forensic psychiatric sub-population 6-8 years after forensic psychiatric evaluation. The aim was to examine the long-term validity of biological markers of psychopathy and antisocial behavior over time. Data on criminal records were obtained at follow-up from the National Council for Crime Prevention. Basic data included findings of psychiatric and psychological assessments, as well as values for serum triiodothyronine (T3) and free thyroxin (FT4), and platelet monoamine oxidase (MAO) activity, all obtained during the forensic psychiatric examination. Criminal recidivists at follow-up had higher serum T3 levels than non-recidivists, and much higher values than normal controls, while their levels of free T4 were lower. The T3 levels in criminal recidivists correlated to psychopathy- and aggression-related personality traits as measured by the Karolinska Scale of Personality. In violent recidivists, a remarkably high correlation was noted between T3 levels and Irritability and Detachment, traits that have previously been linked to the dopaminergic system. Stepwise multiple regression analyses confirmed the relationships of T3 levels and platelet MAO activity with personality traits in criminal recidivists. The predictive validity of biological markers of psychopathy, T3 and platelet MAO, measured during forensic psychiatric investigation, is stable over time. The results indicate chronic alterations of the hypothalamic-pituitary-thyroid axis in this group of subjects.

Abstract
OBJECTIVE To investigate the usefulness of electrical startle responses and thyroid function as supplements to self-report measures of posttraumatic stress disorder (PTSD). METHOD Invitations were sent to all New Zealand Vietnam War veterans known to be living in North Canterbury; 50 responded and the 35 living in or near Christchurch were included. Self-report measures of PTSD (the Davidson Trauma Scale (DTS) and the Symptom Check List (SCL-90-R) ), an eye blink electrical startle response and thyroid function were measured. The DTS was re-administered one to two weeks later to assess short-term test-retest reliability. Six months later the DTS and the electrical startle response were measured again. RESULTS The veterans reported a wide range of PTSD severity, with 15/35 reporting prior diagnosis of PTSD. The DTS showed high short-term test-retest reliability (r = 0.93) and a moderate correlation after 6 months (r = 0.73). It also showed sensitivity to change; in one to two weeks the scores increased by nearly half a standard deviation, possibly because of an imminent "homecoming" march. The DTS and a PTSD scale from the SCL-90-R were highly correlated (r = 0.89). The total triiodothyronine (T3) to free thyroxine (T4) ratio measure of thyroid function correlated poorly with self-report (r < or = 0.27). The electrical startle response also correlated poorly with self-report (r < or = 0.26), showed low internal consistency between left and right sides (r = 0.43), and correlated 0.39 over six months. It was disliked by the veterans and had increased slightly at 6 month follow-up, perhaps because of sensitization. CONCLUSIONS The DTS was reliable and correlated highly with the SCL-90-R PTSD scale. Neither thyroid function nor eye blink electrical startle correlated with each other or with self-report, and reliability was not good for electrical startle. These two measures do not appear to add anything useful to the assessment of PTSD.

Abstract
The aim of this study was to compare aggressive behavior in soldiers with combat-related post-traumatic stress disorder (PTSD), PTSD comorbid with alcohol addiction and alcohol addiction only. Three groups of male combat experienced soldiers with PTSD (n=43), PTSD comorbid with alcohol addiction (n=41) and alcohol addiction (n=39) were compared by Aggression rating scale A-87. PTSD was diagnosed according to DSM-IV criteria and Watson's PTSD rating scale. Alcohol addiction was diagnosed according to DSM-IV criteria and CAGE Questionnaire. Combat-experienced soldiers with alcohol addiction as well as soldiers with combat-related PTSD comorbid with alcohol addiction have a high level of verbal latent aggression (VLA), (F=26.65; P<0.001), physically latent aggression (PLA), (F=37.86; P<0.001), indirect aggression (INA), (F=56.94; P<0.001), verbal manifest aggression (VMA), (F=18.35; P<0.001), and physically manifest aggression (PMA), (F=43.22; P<0.001), vs. soldiers with combat-related PTSD without comorbid conditions. Alcohol addiction is a severe factor in increasing aggression levels in soldiers with PTSD.

Abstract
BACKGROUND Previous magnetic resonance imaging studies of posttraumatic stress disorder reported hippocampal volume loss. The goals of this study were 1) to determine the relationship between hippocampal atrophy and posttraumatic stress disorder in the absence of alcohol abuse, and 2) to test if loss of N-acetylaspartate (a neuron marker) in the hippocampus of posttraumatic stress disorder occurs separate from atrophy. In addition, volume changes in the entorhinal cortex were also explored. METHODS Eighteen male patients with combat-related posttraumatic stress disorder (mean age 51.2 +/- 2.5 years) and 19 male control subjects (mean age 51.8 +/- 3.2 years) were studied using magnetic resonance imaging and Proton magnetic resonance spectroscopic imaging. Both groups had no alcohol and drug abuse during the past 5 years. RESULTS Posttraumatic stress disorder and control subjects had similar volumes of hippocampus and entorhinal cortex. In contrast to volume, N-acetylaspartate was significantly reduced by about 23% bilaterally in the hippocampus of posttraumatic stress disorder when compared with control subjects, and creatine-containing compounds were reduced by 26% in the right hippocampus of posttraumatic stress disorder. CONCLUSIONS N-acetyl asparate and creatine reductions imply that there are hippocampal abnormalities in posttraumatic stress disorder. Furthermore, these metabolite changes seem to be better indicators of posttraumatic stress disorder pathology than volume losses.

Abstract
BACKGROUND It is reported that psychiatric disorders, such as depression and schizophrenia, are associated with changes in serum activity of prolyl endopeptidase (EC 3.4.21.26), a cytosolic endopeptidase, which cleaves peptide bonds on the carboxylside of proline in proteins of relatively small molecular mass. AIMS AND METHODS The aims of the present study were to examine serum PEP activity in patients with post-traumatic stress disorder (PTSD) versus healthy volunteers. PEP activity has been determined by a fluorimetric assay. RESULTS Serum PEP activity was significantly higher in patients with PTSD than in normal volunteers. Serum PEP activity was significantly higher in patients with PTSD and concurrent major depression than in patients with PTSD without major depression. In PTSD patients, there were no significant correlations between serum PEP activity and severity of PTSD symptoms. CONCLUSIONS The results show that PTSD and, in particular, PTSD with concurrent major depression is associated with increased activity of PEP. RELEVANCE these results may be of importance for the (i) neuroendocrine pathophysiology of PTSD since PEP degrades neuropeptides, such as arginine vasopressin (AVP) and thyrotropin releasing hormone (TRH); and (ii) etiology of PTSD, since PEP degrades behaviorally active neuropeptides, such as AVP, TRH, oxytocin, neurotensin and substance P, which play a key role in positive reinforcement, social interactions, emotions and stress responsivity.

Abstract
OBJECTIVE In previous serum thyroid studies, we reported an unusual thyroid profile, including elevated levels of total and free triiodothyronine (T3), total thyroxine (T4), and thyroxine-binding globulin (TBG) with no elevations in free T4 and thyrotropin (TSH) in Vietnam veterans with combat-related posttraumatic stress disorder (PTSD) compared to control subjects. In a subsample of Vietnam veterans, we found a significant positive correlation between total T3, free T3, and PTSD symptoms, specifically hyperarousal symptoms. In the present study, we explored the generalizability of our findings to World War II (WWII) veterans with PTSD. METHOD Clinical symptoms were assessed in and serum thyroid measures were obtained from 12 WWII veterans with PTSD and 18 WWII veterans without PTSD. RESULTS WWII veterans with combat-related PTSD showed elevations of serum total and free T3 with no elevations of free T4 and TSH compared to control subjects, replicating the results of our previous studies. A significant positive relationship between total and free T3 and PTSD symptoms, specifically hyperarousal symptoms, was also replicated in the total WWII group. Elevations of total T4 and TBG were not replicated in the WWII group with PTSD, which may indicate a shift with age in the free/bound dynamics of the thyroid alterations observed. CONCLUSIONS This study supports the observation that the thyroid system is altered in chronic combat-related PTSD. The observed alterations of thyroid function along with PTSD symptoms appear to be chronic, detectable 50 years after the war.
