BACKGROUND: Methylation of the serotonin 3A receptor gene (HTR3A) has been linked to child maltreatment and adult psychopathology. The present study examined whether HTR3A methylation might be associated with mothers' lifetime exposure to interpersonal violence (IPV), IPV-related psychopathology, child disturbance of attachment, and maternal neural activity. METHODS: Number of maternal lifetime IPV exposures and measures of maternal psychopathology including posttraumatic stress disorder (PTSD), major depression and aggressive behavior (AgB), and a measure of child attachment disturbance known as "secure base distortion" (SBD) were assessed in a sample of 35 mothers and children aged 12-42 months. Brain fMRI activation was assessed in mothers using 30-s silent film excerpts depicting menacing adult male-female interactions versus prosocial and neutral interactions. Group and continuous analyses were performed to test for associations between clinical and fMRI variables with DNA methylation. RESULTS: Maternal IPV exposure-frequency was associated with maternal PTSD; and maternal IPV-PTSD was in turn associated with child SBD. Methylation status of several CpG sites in the HTR3A gene was associated with maternal IPV and IPV-PTSD severity, AgB and child SBD, in particular, self-endangering behavior. Methylation status at a specific CpG site (CpG2_III) was associated with decreased medial prefrontal cortical (mPFC) activity in response to film-stimuli of adult male-female interactions evocative of violence as compared to prosocial and neutral interactions. CONCLUSIONS: Methylation status of the HTR3A gene in mothers is linked to maternal IPV-related psychopathology, trauma-induced brain activation patterns, and child attachment disturbance in the form of SBD during a sensitive period in the development of self-regulation.

Women who have experienced interpersonal violence (IPV) are at a higher risk to develop posttraumatic stress disorder (PTSD), with dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis and impaired social behavior. Previously, we had reported impaired maternal sensitivity and increased difficulty in identifying emotions (i.e. alexithymia) among IPV-PTSD mothers. One of the aims of the present study was to examine maternal IPV-PTSD salivary cortisol levels diurnally and reactive to their child's distress in relation to maternal alexithymia. Given that mother-child interaction during infancy and early childhood has important long-term consequences on the stress response system, toddlers' cortisol levels were assessed during the day and in response to a laboratory stressor. Mothers collected their own and their 12-48month-old toddlers' salivary samples at home three times: 30min after waking up, between 2-3pm and at bedtime. Moreover, mother-child dyads participated in a 120-min laboratory session, consisting of 3 phases: baseline, stress situation (involving mother-child separation and exposure to novelty) and a 60-min regulation phase. Compared to non-PTSD controls, IPV-PTSD mothers - but not their toddlers, had lower morning cortisol and higher bedtime cortisol levels. As expected, IPV-PTSD mothers and their children showed blunted cortisol reactivity to the laboratory stressor. Maternal cortisol levels were negatively correlated to difficulty in identifying emotions. Our data highlights PTSD-IPV-related alterations in the HPA system and its relevance to maternal behavior. Toddlers of IPV-PTSD mothers also showed an altered pattern of cortisol reactivity to stress that potentially may predispose them to later psychological disorders.

This paper explores challenges in the treatment of women suffering from disturbances in maternal identification. A review of the psychoanalytic and developmental literature focuses on the frequent finding of early-onset mother-daughter relational disturbance involving maternal narcissistic fragility and exaggerated dependency needs, intergenerational trauma, and related psychopathology including mutual affect dysregulation. A case example of a young woman with a severe anxiety disorder is presented and discussed to illustrate the challenges to the traditional psychoanalytic technique. This patient avoided pregnancy into her late thirties and entered analysis with feelings of inauthenticity, characterological masochism, and a " secret mission" to unmask the witch recurring in her dreams. Through an elaborate working-through of negative maternal transference, the analyst and patient saw through the birth of the patient's authentic self, a new approach to her career, her relationships with men, and her anticipation of the birth of a child by the sixth year of treatment. The author posits that psychoanalytic technique benefits from contemporary, attachment, and trauma research that supports the analyst's playing a more active role in approaching, co-regulating, tolerating, and integrating avoided affects and memory traces that are associated with early-onset relational disturbances worsened by the effects of violence, maltreatment, and loss.

Beginning with his Interpersonal World of the Infant (1985), Daniel Stern suggested that the infant is driven from birth to connect intersubjectively with his caregivers. By the final three months of the first year of life, as the infant begins to use protodeclarative pointing and jointly attends to the outer world, he also begins to jointly attend with his caregiver to their respective intrapsychic worlds, the mental states of his caregiver and himself. Clinically, analysts observe at this crucial point of development of secondary intersubjectivity mothers who, more often than not, respond only selectively and often unpredictably to their infants. In many instances, this may be motivated out of a mother's own need for regulation of emotion and arousal as we have shown in our empirical research. This article elaborates on clinical observations that, for the infant or young child to feel his traumatized mother's affective presence, he must try to enter mother's state of mind, while simultaneously, mother is seeking to self-regulate in the wake or the revival of trauma-associated memory traces, this at the expense of mutual regulation of emotion and arousal. We call this phenomenon traumatically skewed intersubjectivity. We find that children coconstruct with their traumatized mothers a new, shared traumatic experience by virtue of the toddler's efforts to share an intersubjective experience with a mother who is acting in response to posttraumatic reexperiencing. The problem is that the infant or young child has no point of reference to decipher the traumatized mother's social communication. And so, what is enacted leads to a new, shared traumatic event. Both the child's anxiety and aggression can, in this setting, easily become dysregulated, further triggering mother's anxiety and avoidance, leading thus to a vicious cycle that contributes to intergenerational transmission of trauma. Clinical examples and implications for psychoanalytically-oriented parent-infant psychotherapy will be discussed.

The aim of this study was to examine the relationship of maternal interpersonal violence-related posttraumatic stress disorder (IPV-PTSD), associated neural activity in response to mother-child relational stimuli, and child psychopathology indicators at child ages 12-42 months and one year later. The study tested the hypothesis that decreased maternal neural activity in regions that subserve emotion regulation would be associated with child symptoms associated with emotional dysregulation at both time points. Functional magnetic resonance imaging of 42 mothers with or without violence-exposure and associated IPV-PTSD were assessed. Their child's life-events and symptoms/behaviors indicative of high-risk subsequent PTSD diagnosis on a maternal-report questionnaire were measured one year later. Maternal IPV-PTSD severity was significantly associated with decreased ventromedial prefrontal cortex (vmPFC) activation in response to mother-child relational stimuli. Maternal IPV-PTSD severity and decreased vmPFC activation were then significantly associated with a child attachment disturbance at 12-42 months and symptoms/behaviors one year later, that were correlated with emotional dysregulation and risk for child PTSD. Maternal IPV-PTSD and child exposure to IPV were both predictive of child PTSD symptoms with maternal IPV-PTSD likely mediating the effects of child IPV exposure on child PTSD symptoms. These findings suggest that maternal IPV-PTSD severity and associated decreased vmPFC activity in response to mother-child relational stimuli are predictors of child psychopathology by age 12-42 months and one-year later. Significant findings in this paper may well be useful in understanding how maternal top-down cortico-limbic dysregulation promotes intergenerational transmission of IPV and related psychopathology and, thus should be targeted in treatment.

Maternal interpersonal violence-related post-traumatic stress disorder (IPV-PTSD) is known to be associated with impairment of a mother's capacity to participate in mutual emotion regulation during her child's first years of life. This study tested the hypothesis that maternal difficulty in identifying feelings in self and other, as an important dimension of the construct of alexithymia, together with maternal IPV-PTSD, would be negatively associated with maternal sensitivity. Maternal sensitivity to child emotional communication is a marker of maternal capacity to engage in mutual regulation of emotion and arousal. Following diagnostic interviews and administration of the Toronto Alexithymia Scale, 56 mothers and their toddlers (ages 12-42 months) were filmed during free-play and separation/novelty-exposure. Observed maternal sensitivity was coded via the CARE-Index. Maternal IPV-PTSD severity, difficulty in identifying emotions, and lower socio-economic status were all associated with less maternal sensitivity, and also with more maternal controlling and unresponsive behavior on the CARE-Index.

Post-traumatic stress disorder (PTSD) is a disorder that involves impaired regulation of the fear response to traumatic reminders. This study tested how women with male-perpetrated interpersonal violence-related PTSD (IPV-PTSD) differed in their brain activation from healthy controls (HC) when exposed to scenes of male-female interaction of differing emotional content. Sixteen women with symptoms of IPV-PTSD and 19 HC participated in this study. During magnetic resonance imaging, participants watched a stimulus protocol of 23 different 20 s silent epochs of male-female interactions taken from feature films, which were neutral, menacing or prosocial. IPV-PTSD participants compared with HC showed (i) greater dorsomedial prefrontal cortex (dmPFC) and dorsolateral prefrontal cortex (dlPFC) activation in response to menacing vs prosocial scenes and (ii) greater anterior cingulate cortex (ACC), right hippocampus activation and lower ventromedial prefrontal cortex (vmPFC) activty in response to emotional vs neutral scenes. The fact that IPV-PTSD participants compared with HC showed lower activity of the ventral ACC during emotionally charged scenes regardless of the valence of the scenes suggests that impaired social perception among IPV-PTSD patients transcends menacing contexts and generalizes to a wider variety of emotionally charged male-female interactions.

This study found that within a non-referred community pediatrics clinic sample, the severity of mothers' trauma-related psychopathology, in particular, their interpersonal violence-related (IPV) posttraumatic stress, dissociative, and depressive symptoms predicted the degree of negativity of mothers' attributions towards their preschool age children, themselves, and their own primary attachment figure. Results also showed that mothers with IPV-related posttraumatic stress disorder (PTSD) as compared to non-PTSD controls showed a significantly greater degree of negativity of their attributions toward their child, themselves and their primary attachment figure during childhood. The study finally found a significant reduction in the degree of negativity of mothers' attributions only towards their child following a three-session evaluation-protocol that included a form of experimental intervention entitled the "Clinician Assisted Videofeedback Exposure Session(s)" (CAVES), for mothers with IPV-PTSD as compared to control-subjects.
