Trauma and grief 2-7 years after termination of pregnancy because of fetal anomalies--a pilot study.

The aim of the study was to obtain information on the long-term posttraumatic stress response and grief several years after termination of pregnancy due to fetal malformation. We investigated 83 women who had undergone termination of pregnancy between 1995 and 1999 and compared them with 60 women 14 days after termination of pregnancy and 65 women after the spontaneous delivery of a full-term healthy child. Women 2-7 years after termination of pregnancy were expected to show a significantly lower degree of traumatic experience and grief than women 14 days after termination of pregnancy. Contrary to the hypothesis, however, the results showed no significant intergroup differences with respect to the degree of traumatic experience. With the exception of one subscale (fear of loss), this also applied to the grief reported by the women. However, both groups differed significantly in their posttraumatic stress response from women who had given spontaneous birth to a full-term healthy child. The results indicate that termination of pregnancy is to be seen as an emotionally traumatic major life event which leads to severe posttraumatic stress response and intense grief reactions that are still detectable some years later.

Incidental learning of food and emotional words in women with anorexia nervosa.

Prior research suggests that anorexic patients show a memory bias for fattening foods when they are processed in depth or with reference to the self. The present study examined whether anorexic subjects exhibit a bias for fattening foods when these are presented as task-irrelevant distractor stimuli. It also investigated whether anorexic patients pay less attention to emotion stimuli. A sequential word-word evaluation task was administered to 11 inpatients with anorexia nervosa and 11 non-dieting normal subjects. There were four types of distractor words: high caloric foods, positive, negative, and neutral. Anorexic patients recalled no more food words but fewer neutral and positive words than normal subjects. The present data suggest that, compared to healthy young women, anorexic patients show no memory bias for fattening foods when these data are presented as peripheral environmental information. Anorexic patients are perceptually no less sensitive to negative emotional information than normal subjects.

Maternal posttraumatic stress response after the birth of a very low-birth-weight infant.

OBJECTIVE: For parents, the premature birth of a child represents a traumatic event for which they are poorly prepared. To date, the focus of scientific interest has been on maternal psychological stress responses, such as anxiety and depression, or on appropriate coping mechanisms, whereas only scant attention has been paid to the traumatic aspect of the maternal experience after very low-birth-weight (VLBW) birth. The present study is the first to investigate the posttraumatic stress response of mothers after the birth of a VLBW infant in a prospective longitudinal study. METHODS: Fifty mothers of VLBW infants were examined at four measuring time points (1-3 days pp, 14 days pp and 6 and 14 months pp) with respect to posttraumatic symptoms [Impact of Event Scale (IES-R)], psychiatric diagnosis (SKID I for DSM-IV) and the extent of depression [Beck Depression Inventory (BDI) and Montgomery Asberg Depression Scale (MADRS)] and anxiety [State-Trait Anxiety Inventory (STAI) and Hamilton Anxiety Scale (HAMA)]. The control group comprised a group of 30 mothers after the uncomplicated spontaneous birth of a healthy child. RESULTS: At all four measuring timepoints (except 6 months pp), the mothers of the premature infants recorded significantly higher values for traumatic experience and depressive symptoms and anxiety compared with the controls. In contrast to the mothers in the control group, the mothers of the premature infants displayed no significant reduction in posttraumatic symptoms (IES-total), even 14 months after birth. CONCLUSION: The results indicate that the situation of a mother who has given birth to a VLBW infant is a complex, with long-term traumatic event necessitating ongoing emotional support extending beyond the period immediately after the birth.

N-acetylaspartate levels of left frontal cortex are associated with verbal intelligence in women but not in men: a proton magnetic resonance spectroscopy study.

The left frontal cortex plays an important role in executive function and complex language processing inclusive of spoken language. The purpose of this work was to assess metabolite levels in the left and right prefrontal cortex and left anterior cingulum by proton magnetic resonance spectroscopy and relate results to verbal intelligence (Wechsler Adult Intelligence Scale revised) in a sample of college-educated healthy volunteers (dorsolateral prefrontal cortex [DLPFC]: n=52, 23 females, and left anterior cingulum: n=62, 22 females; age range: 20-75 years). In women only, N-acetylaspartate in the DLPFC and in the left anterior cingulate cortex was positively correlated with vocabulary scores. Our data support the hypothesis of existing gender differences regarding the involvement of the left frontal cortex in verbal processing as reflected in different correlations of specific metabolites with verbal scores.

Grief after termination of pregnancy due to fetal malformation.

Termination of pregnancy for fetal malformation is a traumatic event which any woman finds hard to withstand and which entails the risk of severe and complicated grieving. This paper presents three cases illustrating the trauma and coping mechanisms. Grieving continued for over 6 months in all cases and included pathological anxiety and depression. We offer advice and counselling to such women.

Metabolic changes within the left dorsolateral prefrontal cortex occurring with electroconvulsive therapy in patients with treatment resistant unipolar depression.

BACKGROUND: The dorsolateral prefrontal cortex (DLPFC) is involved in the pathophysiology of major depression. In particular, metabolic (functional hypometabolism) and structural alterations have been described. In this study metabolic changes within the DLPFC of severely depressed patients before and after electroconvulsive therapy (ECT) were evaluated by proton STEAM spectroscopy (1H-MRS). METHOD: Twelve severely depressed patients with a diagnosis of major depressive episode, unipolar with melancholic features (DSM-IV), were enrolled, and the left dorsolateral prefrontal cortex (DLPFC) was investigated before and after unilateral ECT by 1H-MRS. Three of the four non-responding patients were remeasured a third time after a combined ECT/antidepressant pharmacotherapy. The results were compared with 12 age- and gender-matched controls. RESULTS: In depressed patients reduced glutamate/glutamine (Glx) levels were measured pre-ECT; Glx concentrations correlated negatively with severity of depression. After successful treatment, Glx increased significantly and levels no longer differed from those of age-matched controls. CONCLUSIONS: Our results indicate that major depressive disorder is accompanied by state-dependent metabolic alterations, especially in glutamate/glutamine metabolism, which can be reversed by successful ECT.

[Termination of pregnancy for fetal abnormality--a traumatic experience?].

The diagnosis of a lethal anomaly of the fetus can affect a pregnant woman in a traumatic way. Almost immediately she has to decide whether she wishes the pregnancy to be terminated or not. Literature shows that such a loss is very difficult to cope with, and can lead to social isolation and depression. Contrary to popular belief the loss felt by the woman is at least the same to that following a stillbirth. Problems arise when the woman has difficulties in expressing her feelings, has a lack of self-esteem or receives very little social support. The prenatal diagnosis evokes an acute grief reaction. Only few studies are available regarding length, course and severity of grief in this case. Although an abortion through a fetal anomaly is a traumatic experience, research is vague on the trauma caused. Present day research of the psychological sequelae after the termination will be summarized. In respect to the current trauma-research lies the question of which psychiatric conditions arise from such a traumatic experience.

[A critique of the construct "alexithymia" and its measurement--the weakness of self-report and the opportunities of an objective assessment approach].

Approximately thirty years ago the term alexithymia was coined but it is still open which characteristics have to be considered core symptoms of alexithymia. A selective review of recent expert definitions reveals dynamism in defining the alexithymia construct. At present, the self-report Toronto-Alexithymia-Scales (TAS) are the most frequently used measures of alexithymia. Empirical findings regarding various aspects of validity (factorial, concurrent, and experimental construct validity data) question the validity of the Toronto-Alexithymia-Scales. Alexithymia as measured by the TAS appears not to be consistently related to physiological, affect decoding or affective vigilance characteristics. The heterogeneity of the results could be due to the fact that non-alexithymic persons such as depressed or socially anxious individuals yield high scores on the TAS; on the other hand self-report appears to be in principle a methodologically inadequate approach for the assessment of alexithymia. Objective or direct measures of alexithymic characteristics as the Levels of Emotional Awareness Scale or the prototypicity analysis of mood diaries based on adjective checklists seem to be promising assessment methods for future research.

[Homeless and mentally ill. Review of recent research and results on a doubly disadvantaged minority].

There are about 200,000 homeless persons in Germany, 35,000 of them living on the streets. They suffer from unemployment, poverty, social isolation and physical impairments. More than two-thirds of them suffer from mental illness as well. Substance abuse predominates, but also schizophrenic and affective disorders and personality disorders show a higher prevalence than among the general population. Comorbidity is found frequently. However, mental disorders are just one of several factors contributing to the process of becoming homeless. Due to the complex combination of mental, physical, social and economic problems of the homeless mentally ill psychiatric care is not sufficient. Yet recent US studies show that a combination of multimodal clinical measures and a network of outpatient assistance can improve both physical and mental health and the social situation. Having established reliable epidemiological data, future research should concentrate on analysing the influence of homelessness on mental health, and on planning and evaluating specific programmes for the homeless mentally ill.

[HIV-1 associated autonomic dysfunction (HIVAD)].

In a controlled prospective study we used peripheral autonomic surface potentials (PASP) and an autonomic test battery (valsalva, 30:15 ratio, deep breathing, sustained handgrip, Schellong test) to evaluate HIV-1 associated autonomic dysfunction (HIVAD) in 38 HIV-seropositive patients. Criteria of exclusion were drug or alcohol abuse, concurrent infections, neoplasms, wasting syndrome and neurotoxic medication. We found increased PASP onset latencies and lower PASP amplitudes even in asymptomatic HIV-infected patients (p < 0.0125, Bonferroni corrected p-value). A mild or marked HIVAD was detected in 21% of the patients each. Heart rate and blood pressure responses were similarly affected. HIVAD was not related to HIV-1 associated changes in sural and tibial nerve conduction parameters. Our data suggest that HIVAD is a frequent complication of HIV-1 infection and that HIV-1 plays a direct role in its pathogenesis. Sympathetic and parasympathetic divisions of the ANS appear to be similarly affected.
