A tract-based spatial statistics study in anorexia nervosa: abnormality in the fornix and the cerebellum.

There has been an increasing interest in white matter abnormalities in patients with anorexia nervosa (AN). However, to date, there have been only a few diffusion tensor imaging (DTI) studies investigating AN, and the results are inconsistent. In this study, we employed tract-based spatial statistics (TBSS), a robust technique for whole-brain analysis of DTI data, to detect white matter abnormalities in AN patients compared with healthy controls. Seventeen women with AN and 18 age matched healthy women were included. The mean body mass index of patients was 13.6 kg/m(2) (controls: 19.9 kg/m(2)). DTI data were acquired on a 3-Tesla magnetic resonance imaging system. Fractional anisotropy (FA) and mean diffusivity (MD) maps were calculated from the DTI data of each patient, and voxel-wise group comparisons of FA and MD were performed using TBSS. Compared with the healthy comparisons, the patients showed a significantly higher MD value in the fornix and lower FA value in the left cerebellum. We also found significant positive correlations between the mean FA value of the left cerebellar hemisphere cluster and BMI, as well as between the mean MD value of the cluster in the anterior body of the fornix and the duration of illness. The results suggest that the white matter abnormalities in the fornix and the cerebellum may be related to the pathophysiology of AN.

Predictors for exacerbation/improvement of postpartum depression--a focus on anxiety, the mothers' experiences of being cared for by their parents in childhood and borderline personality: a perspective study in Japan.

OBJECTIVE: To investigate the course and influencing factors of postpartum depression in women during the child rearing period. METHODS: Data were collected during 0-year-old baby check-ups and a follow-up investigation. 262 participants were included in the analysis. Both surveys employed the Zung Self-Rating Depression Scale (ZSDS). The first also comprised the State Trait Anxiety Inventory, Parental Bonding Instrument (PBI), and Borderline Scale Index, enabling sub-division of participating subjects into healthy/pathological groups. ZSDS group and survey scores were compared using the t-test. RESULTS: The average ages of the children and the ZSDS scores in both surveys were 7.0±3.2 and 21.8±2.4 months, 40.6±7.9 and 40.1±8.7, respectively, with no significant differences among depression scores. When subjects were divided according to individual scale scores, and survey scores compared, depression significantly improved in the high trait/state anxiety group, high PBI maternal care score group, nonborderline personality (BP) trait group, and breast feeding group, whereas depression was significantly exacerbated in the low PBI maternal care score group. DISCUSSION: Postpartum depression characterized by strong anxiety and a depressive state in mothers with favorable psychological backgrounds showed gradual improvement. We noted an exacerbation of depression during the separation period in mothers who had received poor maternal care. We assume that the feeling of abandonment induced by individuation of their children is a major factor. LIMITATIONS: There is concern that some depressive women may have dropped out due to a performance bias. CONCLUSIONS: Sharing our findings about exacerbation/improvement of depression among medical staff may be beneficial for postpartum mothers.

Parental bonding in patients with eating disorders and self-injurious behavior.

AIM: The goal of the study was to investigate the correlations among parental bonding patterns, eating disorders (ED) and self-injurious behavior (SIB). METHODS: The subjects were 80 patients with ED who were divided into two groups based on those that had (n = 25) and had not engaged in SIB at least once in the last month. The patients and 120 healthy control subjects were evaluated using the Eating Disorder Inventory and the Parental Bonding Instrument. RESULTS: On the Parental Bonding Instrument, the ED + SIB group showed significantly lower paternal care compared with the ED/no SIB and control groups. On the Eating Disorder Inventory, the ED + SIB group showed higher body dissatisfaction, and increased maturity fear compared with the other two groups. The total scores and perfectionism and interoceptive awareness differed significantly among the three groups. CONCLUSION: ED + SIB patients had a more severe ED pathology than ED/no SIB patients, and also felt that they had received low paternal care during childhood. Therefore, paternal care may be linked to severe ED pathology.

Factors associated with postpartum depression and abusive behavior in mothers with infants.

AIMS: This study was conducted to examine factors associated with postpartum depression and abusive behavior in mothers with infants. METHODS: Data were collected from baby check-ups in Japan and 413 participants were included in an analysis using: (i) an Original Questionnaire; (ii) the Zung Self-rating Depression Scale (ZSDS); (iii) the Parental Bonding Instrument; and (iv) the Childcare Anxiety Scale (CAS). Covariance structural analyses were performed to examine interconnections among the Parental Bonding Instrument subscales, CAS subscales ('worry about parenting', 'burden of nursing time', 'difficulty of bonding'), ZSDS, 'fear of being abusive', and 'abusive behavior'. RESULTS: Of the 413 mothers, 14.5% showed higher than moderate levels of depression (ZSDS > or = 50). In covariance structural analyses, 'depression' was strongly influenced by 'worry about parenting' in all variances, but was not associated with 'abusive behavior'. 'Worry about parenting' also had a strong influence on 'fear of being abusive', but did not affect 'abusive behavior'. Low 'maternal care' had most influence on 'difficulty of bonding', and 'difficulty of bonding' only affected 'abusive behavior'. CONCLUSIONS: The outcome of this study suggests that excessive worrying related to postpartum depression, 'fear of being abusive', and bonding difficulty are primary predictors of child abuse. Postpartum depression was not a predictor for abusive behavior after exclusion of the impact of bonding difficulties on abusive behavior. Therefore, the correlation between postpartum depression and abusive behavior identified in previous reports may have been influenced by bonding difficulties.
