[Post-traumatic stress disorders (PTSD) and trauma sequel disorders in adolescence]. / Posttraumatische Belastungsstörungen (PTBS) und Traumafolgestörungen in der Adoleszenz.

This text examines post-traumatic stress disorders and trauma sequel disorders in adolescence, focusing in particular on the problem of transition. On the one hand, on the diagnostic level traumatizations are often not PTSD-specific, but rather self-help and self-medication measures as well as alcohol and drug addiction and dissociality, which are often not sufficiently questioned in the adult psychiatric system. On the other hand, it is about the further development and implementation of trauma pedagogical approaches, especially for young people who grow up in critical high-risk constellations or who are already in institutions of youth welfare or integration assistance. Here, not only a blatant lack of initial, further and continuing training for the occupational groups involved is noted, but also a lack of empirical therapy studies.

Assessment of subjective emotional valence and long-lasting impact of life events: development and psychometrics of the Stralsund Life Event List (SEL).

BACKGROUND: Life events (LEs) are associated with future physical and mental health. They are crucial for understanding the pathways to mental disorders as well as the interactions with biological parameters. However, deeper insight is needed into the complex interplay between the type of LE, its subjective evaluation and accompanying factors such as social support. The "Stralsund Life Event List" (SEL) was developed to facilitate this research. METHODS: The SEL is a standardized interview that assesses the time of occurrence and frequency of 81 LEs, their subjective emotional valence, the perceived social support during the LE experience and the impact of past LEs on present life. Data from 2265 subjects from the general population-based cohort study "Study of Health in Pomerania" (SHIP) were analysed. Based on the mean emotional valence ratings of the whole sample, LEs were categorized as "positive" or "negative". For verification, the SEL was related to lifetime major depressive disorder (MDD; Munich Composite International Diagnostic Interview), childhood trauma (Childhood Trauma Questionnaire), resilience (Resilience Scale) and subjective health (SF-12 Health Survey). RESULTS: The report of lifetime MDD was associated with more negative emotional valence ratings of negative LEs (OR = 2.96, p < 0.0001). Negative LEs (b = 0.071, p < 0.0001, ß = 0.25) and more negative emotional valence ratings of positive LEs (b = 3.74, p < 0.0001, ß = 0.11) were positively associated with childhood trauma. In contrast, more positive emotional valence ratings of positive LEs were associated with higher resilience (b = - 7.05, p < 0.0001, ß = 0.13), and a lower present impact of past negative LEs was associated with better subjective health (b = 2.79, p = 0.001, ß = 0.05). The internal consistency of the generated scores varied considerably, but the mean value was acceptable (averaged Cronbach's alpha > 0.75). CONCLUSIONS: The SEL is a valid instrument that enables the analysis of the number and frequency of LEs, their emotional valence, perceived social support and current impact on life on a global score and on an individual item level. Thus, we can recommend its use in research settings that require the assessment and analysis of the relationship between the occurrence and subjective evaluation of LEs as well as the complex balance between distressing and stabilizing life experiences.

Living alone and activation of the renin-angiotensin-aldosterone-system: Differential effects depending on alexithymic personality features.

OBJECTIVE: Living alone is considered as a chronic stress factor predicting different health conditions and particularly cardiovascular disease (CVD). Alexithymia is associated with increased psychological distress, less social skills and fewer close relationships, making alexithymic subjects particularly susceptible to chronic stress imposed by "living alone". Only few studies investigated the renin-angiotensin-aldosterone-system (RAAS) activity in response to chronic stress. We aimed at evaluating the effects of "living alone" as a paradigm for chronic stress on RAAS activity and putatively differential effects depending on alexithymic personality features. METHODS: Alexithymia and serum concentrations of renin and aldosterone were measured in 944 subjects from the population-based SHIP-1 study. Subgroups were formed using the median of the Toronto Alexithymia Scale-20 (TAS-20) and a cohabitation status of "living alone" or "living together". Analyses were adjusted for various psychosocial, behavioral and metabolic risk factors. RESULTS: "Living alone" was associated with elevated plasma renin (p<0.01, ß=0.138) but not aldosterone concentrations in the total sample. On subgroup level, we found associations of "living alone" and elevated renin concentrations only in subjects low in TAS-20 scores (p<0.01, ß=0.219). Interactional effects of alexithymia×cohabitation status were found for the aldosterone-to-renin ratio (p=0.02, ß=-0.234). CONCLUSIONS: The association of chronic stress imposed by "living alone" with increased RAAS activity contributes to explain the relationship of this psychosocial stress condition and increased risk for CVD. In contrast, alexithymic subjects may be less affected by the deleterious effects of "living alone".

Efficacy and Feasibility of a Therapist-Guided Internet-Based Intervention for Older Persons with Childhood Traumatization: A Randomized Controlled Trial.

OBJECTIVE: Although cognitive-behavioral treatment approaches for post-traumatic stress disorder (PTSD) exist, only a small proportion of older adults seeks psychological treatment. Alternative treatment approaches are thus needed to fill the gap between provision and use of psychological interventions. This study aimed to investigate the efficacy and feasibility of an Internet-based, therapist-guided cognitive-behavioral therapy (Internet-based CBT) for older individuals with PTSD symptoms. METHODS: Patients with clinically meaningful (i.e., subsyndromal or greater) PTSD symptoms were randomly assigned to a 6-week treatment group of therapist-guided Internet-based CBT (N = 47; treatment group) or a wait-list group (N = 47; WL). The treatment group was assessed pre- and post-treatment as well as at 3-, 6- and 12-month follow-ups. RESULTS: Linear mixed-effects analyses showed a significant interaction between group (treatment versus WL) and time (pre versus post) for PTSD symptoms with a moderate between-group effect size in favor of the treatment group (d = 0.42). Effects in the treatment group were maintained up to the 12-month follow-up. Findings indicate a significant interaction (group × time) for quality of life (d = 0.39) and self-efficacy (d = 0.38). With regard to the feasibility, attrition rate was very low in both groups (treatment group: 12.8%, WL: 6.4%) and working alliance was very high. CONCLUSIONS: Results suggest that therapist-guided Internet-based CBT is associated with a substantial reduction in PTSD symptoms, and increase in resource-related variables in older adults with (subsyndromal) PTSD. This Internet-based intervention may offer a promising option in a stepped-care approach for older trauma-affected persons who may otherwise not pursue mental health treatment.

Sex- and age-specific associations between major depressive disorder and metabolic syndrome in two general population samples in Germany.

BACKGROUND AND AIMS: Major depressive disorder (MDD) has been associated with the Metabolic Syndrome (MetS). As previous data strongly suggested sex and age effects on this association, this study aimed to analyse the association between MDD and MetS in two general population samples under explicit consideration of sex and age. METHODS: This study analysed cross-sectional data based on two independent general population samples: SHIP-0 (n = 4083; 20-81 years; 49.4% male) and SHIP-TREND-0 (n = 3957; 20-83 years; 49.0% male) that were part of the Study of Health in Pomerania. MDD (SHIP-0: 12.6%; SHIP-TREND-0: 27.2%) was assessed using the Composite International Diagnostic-Screener (CID-S) in both samples. Interview assessment of MDD diagnosis according to Diagnostic and Statistical Manual of Mental Disorders IV (DSM-IV) criteria was performed in SHIP-TREND-0 (18.1% MDD). MetS was defined by abdominal obesity, elevated blood pressure, elevated glucose, elevated triglycerides and reduced high-density lipoprotein cholesterol according to established criteria. Data analysis was performed sex- and age-stratified. RESULTS: Prevalence of MetS was high in both samples: 19.4% of females and 30.2% of males in SHIP-0 and 22.1% and 33.2% in SHIP-TREND-0, respectively. Effect modifications were observed by sex and age on the association between MDD and MetS. Particularly, younger females (20-49 years) with MDD were more often affected by MetS than younger females without MDD: OR = 2.21 (95% CI = 1.39-3.50). This association vanished in elderly participants (50-82 years). CONCLUSION: The data suggest that especially younger (presumably pre-menopausal) females with MDD are more likely to have MetS than those without major depressive disorders, and that age extenuates this association.

Effect of the interaction between childhood abuse and rs1360780 of the FKBP5 gene on gray matter volume in a general population sample.

OBJECTIVE: The FKBP5 gene codes for a co-chaperone that regulates glucocorticoid receptor sensitivity and thereby impacts the reactivity of the hypothalamic-pituitary-adrenal (HPA)-axis. Evidence suggested that subjects exposed to childhood abuse and carrying the TT genotype of the FKBP5 gene single nucleotide polymorphism (SNP) rs1360780 have an increased susceptibility to stress-related disorders. METHOD: The hypothesis that abused TT genotype carriers show changes in gray matter (GM) volumes in affect-processing brain areas was investigated. About 1,826 Caucasian subjects (age ≤ 65 years) from the general population [Study of Health in Pomerania (SHIP)] in Germany were investigated. The interaction between rs1360780 and child abuse (Childhood Trauma Questionnaire) and its effect on GM were analyzed. RESULTS: Voxel-based whole-brain interaction analysis revealed three large clusters (FWE-corrected) of reduced GM volumes comprising the bilateral insula, the superior and middle temporal gyrus, the bilateral hippocampus, the right amygdala, and the bilateral anterior cingulate cortex in abused TT carriers. These results were not confounded by major depressive disorders. In region of interest analyses, highly significant volume reductions in the right hippocampus/parahippocampus, the bilateral anterior and middle cingulate cortex, the insula, and the amygdala were confirmed in abused TT carriers compared with abused CT/CC carriers. CONCLUSION: The results supported the hypothesis that the FKBP5 rs1360780 TT genotype predisposes subjects who have experienced childhood abuse to widespread structural brain changes in the subcortical and cortical emotion-processing brain areas. Those brain changes might contribute to an increased vulnerability of stress-related disorders in TT genotype carriers.

Association between waist circumference and gray matter volume in 2344 individuals from two adult community-based samples.

We analyzed the putative association between abdominal obesity (measured in waist circumference) and gray matter volume (Study of Health in Pomerania: SHIP-2, N=758) adjusted for age and gender by applying volumetric analysis and voxel-based morphometry (VBM) with VBM8 to brain magnetic resonance (MR) imaging. We sought replication in a second, independent population sample (SHIP-TREND, N=1586). In a combined analysis (SHIP-2 and SHIP-TREND) we investigated the impact of hypertension, type II diabetes and blood lipids on the association between waist circumference and gray matter. Volumetric analysis revealed a significant inverse association between waist circumference and gray matter volume. VBM in SHIP-2 indicated distinct inverse associations in the following structures for both hemispheres: frontal lobe, temporal lobes, pre- and postcentral gyrus, supplementary motor area, supramarginal gyrus, insula, cingulate gyrus, caudate nucleus, olfactory sulcus, para-/hippocampus, gyrus rectus, amygdala, globus pallidus, putamen, cerebellum, fusiform and lingual gyrus, (pre-) cuneus and thalamus. These areas were replicated in SHIP-TREND. More than 76% of the voxels with significant gray matter volume reduction in SHIP-2 were also distinct in TREND. These brain areas are involved in cognition, attention to interoceptive signals as satiety or reward and control food intake. Due to our cross-sectional design we cannot clarify the causal direction of the association. However, previous studies described an association between subjects with higher waist circumference and future cognitive decline suggesting a progressive brain alteration in obese subjects. Pathomechanisms may involve chronic inflammation, increased oxidative stress or cellular autophagy associated with obesity.

Interaction among childhood trauma and functional polymorphisms in the serotonin pathway moderate the risk of depressive disorders.

Depressive disorders are influenced by a complex interplay between genetic and environmental factors. Multiple studies support a role of serotonergic pathways in the pathophysiology of depressive disorders. As a rate-limiting enzyme of serotonin synthesis in the brain, tryptophan hydroxylase 2 (TPH2) represents a plausible candidate gene. This also applies to the serotonin reuptake transporter (5-HTTLPR) regulating the availability of serotonin in the synaptic gap. We hypothesize that functional polymorphisms (TPH2: rs7305115, 5-HTTLPR and rs25531) within both genes contribute to the risk of depressive disorders after childhood abuse in adult life. To confirm our results, we investigated two independent samples of Caucasian subjects from the study of health in Pomerania (SHIP-LEGEND: n = 2,029 and SHIP-TREND-0: n = 2,475). Depression severity was assessed by the Beck depression inventory (BDI-II) for LEGEND and the patient health questionnaire (PHQ-9) for TREND-0. Childhood abuse was assessed by the childhood trauma questionnaire. Rs7305115 (TPH2) revealed significant effects in SNP × abuse and SNP × SNP as well as in the three-way interaction. This three-way interaction among abuse, TPH2 and 5-HTTLPR showed a significant effect on depression score (p = 0.023). The SS genotype of 5-HTTLPR was associated with increased depression scores after childhood abuse only in carriers of the low-expression TPH2 GG genotype, whereas the TPH2 AA genotype reversed this effect. Our results support the role of interaction effects of genetic variants within serotonergic pathways. Genetic variants that may decrease the presynaptic serotonin concentration were associated with increased adult depressive symptoms in subjects with childhood abuse.

Integrative testimonial therapy: an Internet-based, therapist-assisted therapy for German elderly survivors of the World War II with posttraumatic stress symptoms.

Trauma-focused cognitive behavioral treatments are known to be effective for posttraumatic stress disorder (PTSD) in adults. However, evidence for effective treatments for older persons with PTSD, particularly elderly war trauma survivors, is scarce. In an open trial, 30 survivors of World War II aged 65 to 85 years (mean, 71.73 years; SD, 4.8; n = 17 women) with PTSD symptoms were treated with a Web-based, therapist-assisted cognitive-behavioral/narrative therapy for 6 weeks. Intent-to-treat analyses revealed a significant decrease in PTSD severity scores (Cohen's d = 0.43) and significant improvements on secondary clinical outcomes of quality of life, self-efficacy, and posttraumatic growth from pretreatment to posttreatment. All improvements were maintained at a 3-month follow-up. The attrition rate was low (13.3%), with participants who completed the trial reporting high working alliance and treatment satisfaction. Results of this study suggest that integrative testimonial therapy is a well accepted and potentially effective treatment for older war trauma survivors experiencing PTSD symptoms.

[Is there an association between intra-familiar sexual abuse and sexual offences in later life?]. / Gibt es eine Assoziation zwischen familiärem sexuellen Missbrauch und späteren Sexualstraftaten?

OBJECTIVE: 12-35% of all sexual delinquents report victimization through early sexual abuse. To date, studies are based on small samples and mostly come from English-language countries. METHODS: As part of an interdisciplinary study on the human rights situation in long-term imprisonment, we examined 1,055 prisoners from 11 countries in Europe with the posttraumatic stress diagnostic scale (PDS) concerning their traumas in relation to their offences. RESULTS: Sexual delinquents who reported own prior sexual abuse within the family had a fourfold increase in committing sexual offences later in their life compared to other offenders. CONCLUSIONS: A detailed trauma history which includes sexual offences within the family is essential for adequate therapy and relapse prevention.

Life- and person-centred help in Mecklenburg-Western Pomerania, Germany (DelpHi): study protocol for a randomised controlled trial.

BACKGROUND: The provision of appropriate medical and nursing care for people with dementia is a major challenge for the healthcare system in Germany. New models of healthcare provision need to be developed, tested and implemented on the population level. Trials in which collaborative care for dementia in the primary care setting were studied have demonstrated its effectiveness. These studies have been conducted in different healthcare systems, however, so it is unclear whether these results extend to the specific context of the German healthcare system.The objective of this population-based intervention trial in the primary care setting is to test the efficacy and efficiency of implementing a subsidiary support system on a population level for persons with dementia who live at home. METHODS AND STUDY DESIGN: The study was designed to assemble a general physician-based epidemiological cohort of people above the age of 70 who live at home (DelpHi cohort). These people are screened for eligibility to participate in a trial of dementia care management (DelpHi trial). The trial is a cluster-randomised, controlled intervention trial with two arms (intervention and control) designed to test the efficacy and efficiency of implementing a subsidiary support system for persons with dementia who live at home. This subsidiary support system is initiated and coordinated by a dementia care manager: a nurse with dementia-specific qualifications who delivers the intervention according to a systematic, detailed protocol. The primary outcome is quality of life and healthcare for patients with dementia and their caregivers. This is a multidimensional outcome with a focus on four dimensions: (1) quality of life, (2) caregiver burden, (3) behavioural and psychological symptoms of dementia and (4) pharmacotherapy with an antidementia drug and prevention or suspension of potentially inappropriate medication. Secondary outcomes include the assessment of dementia syndromes, activities of daily living, social support health status, utilisation of health care resources and medication. DISCUSSION: The results will provide evidence for specific needs in ambulatory care for persons with dementia and will show effective ways to meet those needs. Qualification requirements will be evaluated, and the results will help to modify existing guidelines and treatment paths. TRIAL REGISTRATION: NCT01401582.

Moderation of adult depression by the serotonin transporter promoter variant (5-HTTLPR), childhood abuse and adult traumatic events in a general population sample.

The impact of the promoter polymorphisms of the serotonin transporter (5-HTTLPR) on mood has been studied by two-way interaction models comprising one environmental factor and genotype variants. However, childhood abuse is assumed to be associated with different psychobiological long-term effects than adult traumatic events. Both types of trauma may interact on an individual basis throughout the lifespan moderating the impact of the 5-HTTLPR s allele on depressive disorders. Therefore, the hypothesis of a three-way interaction among the 5-HTTLPR, childhood abuse and adult traumatic experience was tested. Caucasian subjects (1,974) from the general population in Germany (Study of Health in Pomerania (SHIP)) were analyzed. Depressive symptoms were measured with the Beck Depression Inventory (BDI-II). Childhood abuse was assessed with the Childhood Trauma Questionnaire. Adult traumatic events were derived from the SCID interview (DSM-IV) on posttraumatic stress disorder (PTSD). Global three-way interactions among the 5-HTTLPR, adult traumatic experiences and childhood abuse (P = 0.0007) were found. Carriers of the ss or sl genotypes who had been exposed to childhood abuse and to more than two adult traumatic events had higher mean BDI-II scores (16.0 [95% CI 8.4-23.6]) compared to those carrying the ll genotype (7.6 [4.5-10.7]). These results were supported using a second, more severe definition of childhood abuse (P = 0.02). No two-way interactions were observed (P > 0.05). Childhood abuse and adult traumatic events may act synergistically in interaction with the s allele of the 5-HTTLPR to increase the risk for depressive symptoms independently from the lifetime diagnosis of PTSD.

Genetic epistasis between the brain-derived neurotrophic factor Val66Met polymorphism and the 5-HTT promoter polymorphism moderates the susceptibility to depressive disorders after childhood abuse.

BACKGROUND: Based on biological interactions between the serotonergic system and the brain-derived neurotrophic factor (BDNF), BDNF is a plausible candidate for a gene-gene-environment interaction moderating the interaction between the s/l- promoter polymorphism of the serotonin transporter (5-HTTLPR) and childhood abuse. We tested the hypothesis of a three-way interaction with respect to depressive symptoms. METHODS: 2035 Caucasian subjects from the Study of Health in Pomerania (German general population) completed the Beck Depression Inventory (BDI-II) and the Childhood Trauma Questionnaire. All subjects were genotyped for the BDNF Val66Met (rs6265) and the s/l 5-HTTLPR polymorphisms. RESULTS: Tobit regression analyses revealed a three-way-interaction between the three genotypes of 5-HTTLPR and the BDNF genotypes and overall childhood abuse for the BDI-II score (p=0.02). Emotional abuse carried the main effect of the interaction (p=0.008). The s/s genotype of the 5-HTTLPR exerted its negative impact on mental health after childhood abuse only in the presence of the BDNF Val/Val genotype but not in the presence of the BDNF Met allele. In contrast, the l allele of the 5-HTTLPR also emerged as a genetic risk factor for depression in carriers of one or two Met alleles. CONCLUSIONS: Our results point to a gene-gene-environment interaction that relevantly impacts on the role of the s/s genotype of the 5-HTTLPR in childhood abuse: Depending on the BDNF background (Val/Val versus Met allele) the s/s genotype showed either protective or risk properties with regard to depressive symptoms.

Differential effects of childhood abuse and neglect: mediation by posttraumatic distress in neurotic disorder and negative symptoms in schizophrenia?

Dissociation, though understood as a response to trauma, lacks a proven etiology. The assumption of a dose-response relationship between trauma, dissociation and Schneiderian symptoms led to the proposal of a dissociative subtype of schizophrenia characterized by severe child maltreatment, dissociation and psychosis. Child maltreatment and dissociation are common features of neurotic disorders as well, and the link between trauma, dissociation, and hallucinations is not specific for schizophrenia. This study compares childhood abuse and neglect, posttraumatic distress and adult dissociation in patients with psychotic vs. non-psychotic disorder. Thirty-five participants with non-psychotic disorder and twenty-five with schizophrenia were analyzed using the Scale for the Assessment of Positive Symptoms (SAPS), the Scale for the Assessment of Negative Symptoms (SANS), the Montgomery-Åsberg Depression Rating Scale (MADRS), the Posttraumatic Stress Diagnostic Scale PDS (PDS), the Childhood Trauma Questionnaire (CTO) and the Arbeitsgemeinschaft Methodik und Dokumentation in der Psychiatrie (AMDP)-module on dissociation. Trauma and clinical syndromes were compared by means of T-testing and logistic regression between 1) the diagnoses and 2) groups with and without post-traumatic stress disorder (PTSD), marked dissociation and psychotic symptoms. While non-psychotic disorder was related to abuse, schizophrenia showed an association with neglect. Childhood trauma predicted posttraumatic symptomatology and negative symptoms. Childhood abuse and neglect may effectuate different outcomes in neurotic and psychotic disorder. The underlying mechanisms, including dissociation, dovetail with cognitive, emotional and behavioural changes involved in depression, posttraumatic distress and chronic schizophrenia symptoms rather than being directly linked to trauma.

Childhood maltreatment, the corticotropin-releasing hormone receptor gene and adult depression in the general population.

Dysregulations of the hypothalamic-pituitary-adrenal (HPA) axis have been implicated in the pathogenesis of depressive disorders and the corticotropin-releasing hormone (CRH) was found to modulate emotional memory consolidation. Recently, two studies have reported an interaction between childhood abuse and the TAT-haplotype of the CRH-Receptor Gene (CRHR1) connecting childhood adversities and genetic susceptibility to adult depression. We tested the hypothesis of an interaction of childhood maltreatment with single nucleotide polymorphisms (SNPs) and haplotypes of the CRHR1 gene not previously investigated. Caucasian subjects (n = 1,638) from the German general population (Study of Health in Pomerania, SHIP) were analyzed. As in the previous studies, childhood abuse and neglect were assessed with the Childhood Trauma Questionnaire (CTQ) and depression with the Beck Depression Inventory (BDI-2). The CRHR1-SNPs were genotyped on the Affymetrix Genome-Wide Human SNP Array 6.0 platform. We identified an interaction between the TAT-haplotype and childhood physical neglect. The interaction with physical neglect showed significant (P < 0.05) results in 23 of the 28 SNPs, with rs17689882 (P = 0.0013) reaching "gene-wide" significance. Although we did not replicate the specific interaction of abuse and the TAT-haplotype of the CRHR1 gene we confirmed the relevance of an interplay between variants within the CRHR1 gene and childhood adversities in the modulation of depression in adults. The largest effect was found for rs17689882, a SNP previously not analyzed. Relevant sample differences between this and prior studies like lower BDI-2 scores, less childhood maltreatment and higher psychosocial functioning may account for the differences in gene-environment interaction findings. © 2010 Wiley-Liss, Inc.

[MMSE for survival prognostics in dementia]. / MMST zur Uberlebensprognostik bei Demenz.

OBJECTIVE: Evaluation of the predictive power of the Mini-Mental State Examination (MMSE) for survival analyses of dementia patients. METHODS: In an 8-year follow-up study for 145 dementia outpatients the survival and relative death risks (hazard ratios) were calculated with Kaplan Meier and Cox-regression analyses. RESULTS: Following Cox-regression the relative death risk increases by 36.2 % per severity level of dementia (mild / moderate / severe), p = 0.023. Per single MMSE point lost, the relative death risk rises by 4.1 % (p = 0.005). Kaplan Meier analysis supports the result. CONCLUSIONS: MMSE scores may in fact be used for dementia survival prognoses in counseling family and professional caregivers of dementia patients, but also for socioeconomic management of the increasing dementia burden for society.

[Prevalence and familiarity of personality disorders in Germany: results of the Greifswald family study]. / Prävalenz und Familiarität von Persönlichkeitsstörungen in Deutschland: Ergebnisse der Greifswalder Familienstudie.

BACKGROUND: There are only few data about the prevalence and familiarity of personality disorders (PD) in population based samples in Germany. Moreover, nearly no information exists for the prevalence of PDs among young adults. Thus, in the current study we examined the prevalence, familiarity and psychopathology of PDs, whereby middle-aged adults (about 45 years old) as well as the adult children of these persons (about 20 years old) were examined. METHODS: Participants were interviewed with the Structured Clinical Interview for Personality Disorders (SCID-II) which is based on the DSM-IV criteria for PDs and with the SCL-90. The sample consisted of 411 parents and their adolescent children (n=334). RESULTS: The prevalence for PDs was 11.2% in the parent sample and 14.7% in the adolescent sample. Cluster-B personality disorders (Cluster-B-PDs) were more often diagnosed in the adolescent sample, in particular. Moreover, we did find an elevated risk for children of parents with a PD than for children of parents without a PD to develop a PD where the former group also displayed elevated values with regard to their psychopathology. CONCLUSIONS: This study underlines the importance of PDs in community-based samples. The implications of our findings for treatment and classification of PDs are discussed.

Serotonin transporter gene (SLC6A4) promoter polymorphisms and the susceptibility to posttraumatic stress disorder in the general population.

OBJECTIVE: There has been debate whether polymorphisms within the serotonin transporter-linked polymorphic region (5-HTTLPR) moderate susceptibility to posttraumatic stress disorder (PTSD). The authors investigated 5-HTTLPR genotypes and their interaction with the number of traumatic events in the prediction of PTSD in a general population sample. METHOD: Analyses were based on data from 3,045 subjects who participated in the Study of Health in Pomerania. All participants were assessed with the PTSD module of the Structured Clinical Interview for DSM-IV. The short (S)/long (L) polymorphism of 5-HTTLPR (rs4795541) and the A-G polymorphism (rs25531) were genotyped. RESULTS: Among the participants, 1,663 had been exposed to at least one traumatic event, and 67 (4.0%) developed PTSD. Among those who had experienced less than three traumatic events, the lifetime prevalence of PTSD was 2.6%, 3.5%, and 4.3% for those with zero, one, and two L(A) alleles, respectively, but the lifetime prevalence was 0%, 7.3%, and 19.6%, respectively, among those with three or more traumatic experiences. This finding suggests that there is an additive excess risk for frequent trauma in the L(A)/L(A) genotype, which was confirmed by the relative excess risk due to interaction (RERI). In allelic analysis, RERI was 3.3. Thus, the odds ratio for PTSD in L(A) allele carriers exposed to three or more traumas was 3.3 times higher as a result of the interaction between PTSD and the L(A) allele. CONCLUSIONS: An additive gene-environment interaction with the high expression L(A) allele of 5-HTTLPR and frequent trauma in PTSD was found. The attributable proportion indicated that more than 60% of all L(A) allele carriers who were exposed to three or more traumas developed PTSD as a result of an interaction between genotype and exposure.

Impact of forced displacement during World War II on the present-day mental health of the elderly: a population-based study.

BACKGROUND: The effects of traumatization among the elderly is a neglected topic in research and clinical settings. Forced displacement of civilians is one of the main traumatic features of modern armed conflict. Roughly 12 million German people were displaced in World War II (WWII) and to our knowledge there has been no representative study investigating the mental health outcomes of such trauma in the elderly population. The survey assessed whether current depression, anxiety, resilience and life satisfaction were significantly associated with forced displacement in WWII. METHODS: A nationwide representative face-to-face household survey was conducted in Germany. A representative sample of the German population aged 61 years or older (N = 1513 participants, N = 239 displaced in WWII) was approached using 258 sample points. Measurements included depressive symptoms (PHQ-2), anxiety (GAD-7), resilience (RS-11), general and domain-specific life satisfaction (FLZ(M)) and sociodemographic variables. RESULTS: Forced displacement in WWII is significantly associated with higher levels of anxiety and lower levels of resilience and life satisfaction 60 years later. In regression analyses, forced displacement in WWII significantly predicted current anxiety (beta 0.07; p < 0.01), life satisfaction (beta -0.06; p < 0.05) and resilience (beta -0.07; p < 0.01). CONCLUSION: To our knowledge this is the first nationwide representative survey to examine the late-life effects of forced displacement, particularly of persons displaced during WWII in Germany. Further research is needed to identify mediating variables and to evaluate psychotherapeutic interventions in elderly trauma survivors.

[Executive dysfunctions in female patients with borderline personality disorder with regard to impulsiveness and depression]. / Exekutive Dysfunktionen bei Patientinnen mit Borderline-Persönlichkeitsstörung unter Berücksichtigung von Impulsivität und Depressivität.

INTRODUCTION: Because of the presence of pronounced impulsiveness and affective dysregulation in subjects with Borderline Personality Disorder (BPD) executive dysfunctions have been suspected. Previous studies in this area revealed inconsistent results. However, most of these studies did not control for comorbidity (e. g. impulsiveness, depression) and current medication of participants. The aim of this study was, therefore, to investigate executive (dys)functions in patients with BPD and healthy controls controlling for impulsivity. Furthermore, a second control group with depression was included to test the specificity of the results. METHOD: 24 unmedicated, female BPD patients as well as 24 healthy controls were matched for age, sex, and intelligence. Additionally, 22 female subjects with a life-time diagnosis of depression were included. All subjects completed a neuropsychological test battery assessing executive functions. RESULTS: No significant differences in executive functioning were found between the three groups. BPD patients showed, however, a decreased ability to delay a gratification compared with controls. CONCLUSION: These results implicate that BPD patients have deficits in motivational areas while other executive functions are not or only marginally involved.
