ABSTRACT

The deliberate killing of a child by its mother is abhorrent and is associated in the minds of many with mental illness and in particular with postnatal depression. However, at least 50% of perpetrators are neither "mad" nor "bad", and mothers who kill children are not "unhinged" by pregnancy or childbirth. We propose a different explanation: "blind rage" or "overwhelmed syndrome", whereby parents, stressed to breaking point by sleep deprivation or incessant baby crying, respond by lethally harming their child contrary to previous behaviour. The roots of this blind rage may be found in psychosocial disturbances, including the mother's own unsatisfactory experience of parenting which has caused attachment disorders. The legal framework guiding decisions to prosecute and structuring sentencing decision-making following conviction should acknowledge the exceptional stress experienced by such mothers postnatally. Health professionals including midwives and obstetricians should increase their vigilance and arrange referrals for mothers at risk of causing harm or committing infanticide.

ABSTRACT

While denial of pregnancy and neonaticide are rare, they are potentially associated and share some risk factors. Neonaticide has been proposed as the extreme outcome of a denial of pregnancy. However, the process leading to such a possible outcome is not yet fully understood. The primary goal of this essay is to examine the various definitions and ambiguities surrounding the denial of pregnancy. The case of a young woman with a history of two denied pregnancies with diverse characteristics and outcomes, the latest of which resulted in neonaticide, is then reported and examined. A forensic psychiatric evaluation was also performed to reconstruct the woman's mental state at the time of the crime. The forensic pathological analysis of the newborn, abandoned near the sea while still alive, is described. The victim's body showed signs of shaken baby syndrome. We contend that differing levels of awareness during a denial of pregnancy might not be predictive of the potential delivery outcome in terms of threat to the newborn's survival, according to the forensic pathological and psychopathological data of the current case. Early identification of women affected by denial of pregnancy who pose a danger of committing infanticide is hampered by both intrinsic traits (dissimulation, unawareness, low propensity to seek assistance) and environmental factors (isolation, low socioeconomic level, poor education.). A previous history of denial of pregnancy should activate health and support services to reduce the potential risks for the mother and the child.

ABSTRACT

Denial of pregnancy is a public health problem due to maternal, fetal, and neonatal morbidity, affecting both physical and mental health. It generally involves an absence of the physical signals associated with pregnancy such as abdominal swelling, amenorrhea, weight gain, or even perception of fetal movements. Despite the potential consequences for mother and child, there is still little data on its clinical features and the neurocognitive mechanisms involved. In this paper, we provide an update on the clinical, socio-demographic, and psychopathological characteristics of pregnancy denial based on contemporary scientific literature. We first define denial of pregnancy by referring to the history of the concept, previous definitions, and nosographic classifications. We then detail the clinic of denial by distinguishing the physical and psychological symptoms of this disorder, then the socio-demographic, gynecological, and psychiatric characteristics. We describe the consequences of denial on the mother, infant, and the dyad, referring to situations of cryptic neonaticide. Finally, we show the importance of perinatal neuroscience research on maternal interoception to understand the mechanisms involved in denial of pregnancy, and improve their medical management in clinical practice.

ABSTRACT

WHAT IS KNOWN ON THE SUBJECT?: The phenomenon of child killing (neonaticide, infanticide or filicide) is a rare event that cannot be fully explained by a single construct as each case involves the unique life circumstances of each woman who committed the act(s). WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE?: The majority of women who committed neonaticide, infanticide or filicide regretted the act and regretted not seeking help from family and healthcare professionals. Women who committed neonaticide, infanticide or filicide in the main had complex circumstances characterised by poverty, abusive relationships, poor family and social support or over reliance on family supports and mental health issues. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Women require a clear plan of what to do if they feel overwhelmed with caring for a baby or child. Healthcare professionals involved with women in the perinatal period need to explore further women's expressions of "not being ready to be a mother" which for some women may be pathological and require further assessment. Women need to be made aware of the support service pathways available to them during the perinatal period and beyond. Further research is needed to explore and learn from women's experiences to reduce child homicide mortality and support women and their families. ABSTRACT: INTRODUCTION: Meaning and personal experiences of the acts of neonaticide, infanticide and filicide have rarely been investigated from the perspectives of the women who committed those acts. AIMS: To identify and synthesise evidence on the perspectives of women directly involved in the complex phenomena of neonaticide, infanticide or filicide from the evidence available on their unique point of view and how these experiences have affected women's lives. To understand how the experiences and perceptions of women who engaged in child killing present similarities or differences according to the child's age at time of death. METHODS: Qualitative primary studies published in English were included if they explored the experiences of women who engaged in neonaticide, infanticide or filicide. Methodological quality was assessed using the qualitative Critical Appraisal Skills Programme (CASP) checklist. A thematic analysis framework guided the synthesis. RESULTS: Seven papers reporting on five studies met the inclusion criteria for the review. Three analytical themes were identified: Not ready to be a mother; Intentionality and premeditation in the context of trauma and mental health issues; Sorrow of regret. DISCUSSION: The majority of women who committed neonaticide, infanticide or filicide had complex psychological, social and personal circumstances and in the main regretted the act and regretted not seeking help from family and healthcare professionals. Healthcare professionals in contact with women during the perinatal period and beyond need to be aware of the profiles of vulnerable women and undertake holistic integrated assessments to identify the woman's personal context, changes in interpersonal relationships, social isolation or over reliance on family supports and changes in mental health status or new onset of mental health conditions. IMPLICATIONS FOR PRACTICE: Women require a clear plan of what to do if they feel overwhelmed with caring for a baby or child. Healthcare professionals involved with women in the perinatal period need to explore further women's expressions of "not being ready to be a mother" which for some women might be pathological and require further assessment. Women need to be made aware of the support services pathways available to them during the perinatal period and beyond. Further research is needed to explore and learn from women's experiences of each of the phenomena separately to reduce child homicide mortality and support women and their families.

ABSTRACT

The objective of the present study consists of the juridic-anthropological analysis of the infanticide, a phenomenon that nowadays is highly existent within the context of crime-settings. Particular consideration has been given to the legal developments of the infanticide act, which occurred simultaneously with the mutation of the socio-cultural contexts. Because the legislative process of the infanticide act has not evolved since 1981, it was possible to underline the criticisms and the inadequacy of such norm. Indeed, the legal norm has not always been able to provide an exhaustive answer concerning cases of infanticide. The process of humanisation of the law led to the introduction of a legal system, which describes the infanticide act as a condition of material and moral abandonment. This has become uncertain and ambiguous to interpret, risking to relegate the legislative matters of infanticide only to exceptional cases. The current study aims to highlight the criticisms and hypothesised different reform perspectives.

ABSTRACT

BACKGROUND: The global suicide occurrences have been aggravated because of COVID-19 crisis-related issues such as fear of infection, the financial crisis, being infected with COVID-19, loneliness, social boycott, etc. Although two studies reported about the seven dyadic suicidality cases (i.e., suicide pacts), child homicide-suicide has not been studied. CASE PRESENTATION: On 14 May, two dead bodies (i.e., a 30-years old Indian woman and her six-month-old baby) were found in a Riyadh apartment complex. The perpetrator (a person who kills the others and later commits suicide) - a trained nurse, was in search of a job. The woman's husband was recently retrenched from his technician job at a company in Madinah Airport. Her husband was admitted to a hospital with symptoms related to the COVID-19 infection four days before the suicide incidence. The 70-year-old mother-in-law alerted the neighbors after finding that the apartment is locked from inside and there was no response on knocking the doors. After this, the neighbors gathered and called the police. Police found two dead-bodies after opening the flat and suspected that the child was killed before the woman committed suicide. CONCLUSIONS: Based on the present findings, further child filicide-suicide possibilities in families with economically distressed and/or positive COVID-19 status are expected. Hence, proper financial supports, providing authentic information (COVID-19), and mental health promotional strategies are suggested for decreasing incidences of COVID-19 related infanticide-suicide cases.

ABSTRACT

INTRODUCTION: Filicide is an act of terrible violence that generates dismay and astonishment and invites everybody to ask: why? AIM: As the transition to motherhood is a critical period for any woman, requiring the activation of deep personality resources, the aim of this study was to deepen our knowledge of the personality profiles of new mothers by comparing a sample of 16 women who had killed their own child ("filicide mothers") with women who had murdered someone outside of their family ("non-family homicide women"). METHOD: All of the women had a similar psychiatric diagnosis, as assessed by the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I). All were assessed by the Minnesota Multiphasic Personality Inventory 2 (MMPI-2) 2 to 4 years after the court's judgment. A Kruskal-Wallis test and two-step cluster analysis were performed to determine whether a specific personality profile could distinguish filicide mothers from non-family homicide women. RESULTS: Years after the act, few filicide mothers showed symptoms of psychopathology; rather, they appeared functional and untroubled. In contrast, non-family homicide women showed a pathological mean profile. CONCLUSIONS: The results may indicate conscious attempts made by filicide mothers to avoid negative evaluations, minimize symptoms, and deny psychological suffering. These may indicate personality risk factors that could help clinicians recognize and intervene in cases where a woman presents a severe mental illness before, during, and following the birth of her child.

ABSTRACT

This article presents formative research on the practice of infanticide, the intentional killing or fatal neglect of a child less than one-year-old. We hypothesised that the abortion law in Senegal, one of the most restrictive in the world, contributes directly to the incidence of infanticide. We conducted a quantitative survey of 1016 women of reproductive age living in Senegal, and in-depth interviews with a sub-sample of 28 participants. Quantitative survey data were analysed to describe the frequencies, means, and ranges of key outcome variables. Qualitative data were analysed using modified grounded theory to identify key themes in the data. Awareness of infanticide was moderately high (60.3%) in the survey sample, and was primarily obtained through personal experience, rumours, and/or the media. Participants described two broad categories of infanticide, including passive infanticide through abandonment of the infant, versus active infanticide through suffocation, drowning or other means. Participants explicitly viewed infanticide as a direct result of the severe legal restrictions on abortion in Senegal, as well as the powerful social norms that dictate what is considered acceptable versus unacceptable childbearing in the country. Findings support the hypothesis that abortion laws and policies contribute to the occurrence of infanticide in Senegal, and suggest the need for additional, targeted research to better understand this link, and how findings can be used to inform policy reform.

ABSTRACT

In Nepal, it is considered sinful for a woman to have sexual intercourse before marriage while the male is exonerated. The female will be branded a loose character outcast by family and society. Only a small percentage of women who feel the other way and stand mentally strong or who have family support come out to seek justice. Despite the stringent law, the loopholes in the justice mechanism re-victimise female victims. We report a case where a young unmarried pregnant woman who gave birth alone was charged with infanticide.

ABSTRACT

The recent conceptualisation of bipolar disorder as a neuroprogressive illness has highlighted the potential importance of prevention and early intervention in high-risk populations. Undiagnosed bipolar disorder early in the disease course is associated with adverse clinical outcomes and impaired functioning for patients, which in turn has economic consequences. Despite the mounting evidence that childbirth is one of the most potent and specific triggers of manic symptoms, studies are not available on the effectiveness of targeted interventions in the prevention of bipolar disorder in women who have recently given birth. In this Personal View, we describe the clinical characteristics of women at risk of developing bipolar disorder after childbirth, before discussing opportunities for prevention and early intervention and outlining challenges in the assessment and management of women at risk of transitioning to bipolar disorder after childbirth. Existing evidence, although scarce, supports a clinical staging model by which at-risk women are managed with a variety of behavioural and pharmacological interventions aimed at preventing bipolar disorder. Close monitoring and early intervention might reduce the risk of hypomanic or manic symptoms in women at risk of developing bipolar disorder after childbirth; however, the potential benefits of early identification and intervention need to be carefully balanced against the additional risks for affected women.

ABSTRACT

Several studies focused on mothers' psychopathological and environmental risk factors linked to filicide, to understand the genesis of this violent act. Considering the transition to motherhood a critical period for any woman, requiring the activation of deep personality resources, the aim of this study was to detect, in a sample of 16 filicide women hospitalized in Italian Forensic Psychiatric Hospitals, the recurrent characteristics with a specific focus on personality traits. Women were assessed using Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I), Big Five Inventory (BFI) and Temperament and Character Inventory (TCI). The BFI and TCI profiles seem to overlap showing a personality profile characterized by a rigid control of aggressive impulses, the avoiding of unconscious fears and the masking of feelings of negativity. Examining the mother's mental state with respect to personality traits, could help clinicians to detect specific temperament patterns that may carry out impulsive violent behaviors, if correlated with other psychopathological and environmental factors.

ABSTRACT

Although filicide is of serious concern, it is poorly understood in Malaysia. Our interviews with health and policy professionals revealed that they attribute responsibility for filicide to women's failure to comply with social norms and religious teachings. This research sought to understand the meaning of and background to filicide from the perspectives of women who have been convicted of filicide in Malaysia. In-depth interviews were conducted in person with all eligible and consenting women convicted of filicide and incarcerated in prisons or forensic psychiatric institutions. Women's accounts were translated into English and analysed using interpretative phenomenological analysis and interpreted using narrative theory. Interviews with nine women convicted of filicide yielded evidence that others were implicated in the crime but punished less severely, if at all, and that the women had experienced lifelong gender-based violence and marginalisation with minimal access to health and social care. These findings illuminate an inadequately understood phenomenon in Malaysia and reveal why existing strategies to reduce filicide, which reflect key stakeholders' views, have had little impact. They reveal the pervasive harm of violence against women and children and its link to filicide.

ABSTRACT

Pregnancy and motherhood are often presented as natural and unproblematic for women. The fact that there are some women who engage in violent behaviour towards their unborn child suggests that motherhood is not as unproblematic as we are led to believe. This paper presents six previously unpublished cases of foetal abuse that is physical assaults on the foetus by the mothers themselves, and examines how the prevailing myth of the good mother might be further endangering mothers and their unborn children. So far, the research suggests there are some common, possibly co-occurring, features that might be an antecedent to foetal abuse: unplanned pregnancies, prior mental health issues in the mother, trauma, pregnancy denial up to 20 weeks or until birth, and ideation of harm correlated to in utero movements.

ABSTRACT

OBJECTIVE: The aim of this study was to review the history, legislation, and psychiatric perspective of filicide, to compare the characteristics of mothers who committed neonaticide versus infanticide, and to discuss the infanticide law in Hong Kong. METHODS: Data of mothers remanded to the Siu Lam Psychiatric Centre from 2008 to 2016 for filicide were reviewed, as were data of filicide from the Child Fatality Review Reports published by the Social Welfare Department. RESULTS: From 2008 to 2016, eight mothers were remanded to Siu Lam Psychiatric Centre for filicide. Four were convicted of infanticide; the other four were convicted of manslaughter. Those convicted of infanticide were single and aged <18 years. They had concealed their pregnancies and received no antenatal care. They delivered at home and then either smothered or abandoned the newborn. They reported no suicidal attempts after the index offence and had no record of mental illness. They were given supervision orders instead of prison sentences. In contrast, those convicted of manslaughter were in their 30s and married. They were documented to have killed the victims by charcoal burning, strangulation, mutilation, or defenestration. They all attempted suicide immediately after the killing and had histories of mental illness: paranoid schizophrenia (n = 2), severe depressive disorder with psychotic symptoms (n = 1), and recurrent depressive disorder (n = 1). They were sentenced to Hospital Orders for unspecified periods. CONCLUSIONS: In Hong Kong, the incidence of maternal filicide is low. However, the infanticide provision grants leniency to mothers, including those who show no evidence of mental illness.

ABSTRACT

Peripartum psychosis is a rare but serious psychiatric disorder characterized by the presence of a mood episode with psychotic features. Although controversy surrounds the nosological status of peripartum mental disorders, these conditions continue to be of exceptional interest to the medical and forensic mental health communities. The aim of this study was to report a rare case of prepartum psychosis which escalated to the endpoint of neonaticide and summarize literature on peripartum mental disorders and infanticide. A 30-year-old mother murdered her newborn with the spike of her serum delivery system and planned to commit suicide while in hospital after hallucinating due to an acute puerperal psychotic disorder with a prepartum onset and postpartum deterioration. Her disorder was not managed until neonaticide. Throughout this paper, the significance of a multidisciplinary approach for the optimal management of these incidents is highlighted and diagnostic as well as therapeutic issues are addressed.

ABSTRACT

OBJECTIVES: Suicide-homicide could be defined as a "suicidal" behaviour, which also includes the death of at least one other individual and sometimes up to hundreds. This literature review intends to highlight some characteristic features that might be found amongst the various types of suicide-homicide. It is a complex phenomenon which can occur in different situations, from a familial and somehow intimate setting (filicide, uxoricide, marital homicide…) to a public one (workplace shooting, school shooting), including a wide range of victims, from a single victim in marital cases of suicide-homicide to hundreds of victims in certain types, such as suicide by aircraft or warrior-like multi-homicids in terrorist acts. This literature review offers a combination of data emanating from scientific publications and case studies from our practices in an attempt to insulate some common factors. A thorough examination of the offenses unravels complex processes, ideations, M.O and peculiar cognitive impairments in which the familial suicide-homicide could be rooted. Mass murders might be caused also by a psychopathological alloy, made of Grandiose Self and sub-depressive and even paranoid ideations. Concerning the terrorism and multi-homicide-suicide, this is far more complex phenomenon and is defined by a group-process enrolment and ideological conviction. Beyond epidemiological studies, both descriptive and statistical, this paper's objective is to isolate a hypothesis about a psychopathological ground from which a criminological mechanism could emerge. Despite the lack of blatant psychosis, some traits might be identified in suicide-homicide cases - such as paranoid, psychopathic, narcissistic, melancholic - which can intertwine, potentiate one with another forming a distorted view of the world. The offense dynamic is possibly composed of preparatory behaviours, triggers, the use of death as a narcissistic support, identity choices… METHODS: The data were collected from scientific publications, personal cases, and open source. RESULTS: Despite the variety of behaviours included in this typology, we were able to identify a few mechanisms that could be found in two types of suicide-homicide [Private suicide-homicide (within the family circle) vs. Public space suicide-homicide (suicide by aircraft, school shooting…)]. DISCUSSION: Suicide-homicide phenomenon is the result of the interaction of societal, ideological, psychopathological and criminological elements which burst out in a lethal and paroxystic gesture. Psychiatrists and psychologists may have an important part to play in modelling a pattern to better understand it.

ABSTRACT

The psychological, sociological and evolutionary roots of conspecific violence in humans are still debated, despite attracting the attention of intellectuals for over two millennia. Here we propose a conceptual approach towards understanding these roots based on the assumption that aggression in mammals, including humans, has a significant phylogenetic component. By compiling sources of mortality from a comprehensive sample of mammals, we assessed the percentage of deaths due to conspecifics and, using phylogenetic comparative tools, predicted this value for humans. The proportion of human deaths phylogenetically predicted to be caused by interpersonal violence stood at 2%. This value was similar to the one phylogenetically inferred for the evolutionary ancestor of primates and apes, indicating that a certain level of lethal violence arises owing to our position within the phylogeny of mammals. It was also similar to the percentage seen in prehistoric bands and tribes, indicating that we were as lethally violent then as common mammalian evolutionary history would predict. However, the level of lethal violence has changed through human history and can be associated with changes in the socio-political organization of human populations. Our study provides a detailed phylogenetic and historical context against which to compare levels of lethal violence observed throughout our history.

ABSTRACT

BACKGROUND: Catatonia is a neuropsychiatric syndrome with motor and behavioural symptoms. Though usually occurring in patients with schizophrenia and mood disorders, this syndrome may also be associated with neurological diseases or general medical conditions. Few cases of catatonia associated with autoimmune disorders have been described. CASE PRESENTATION: Here, we report the case of a 27-year-old woman diagnosed with Hashimoto's encephalitis (HE) who attempted suicide and infanticide by defenestration. As she presented risk factors for postpartum psychosis, she was treated principally with antipsychotics. Despite adequate treatment for psychosis, symptoms worsened and she developed catatonia. Complementary investigations showed elevated titres of anti-thyroglobulin and anti-thyroperoxidase antibodies (200 and 10 times, respectively, as compared to normal levels) and electroencephalography were suggestive of encephalopathy. In the presence of an otherwise unexplained neuropsychiatric condition, HE was suspected and oral prednisolone was introduced. Psychiatric symptoms improved dramatically within 72 h and the patient was still free of any symptom 3 years later. CONCLUSION: Catatonia of organic aetiology should always be considered before a psychiatric aetiology especially in case of clinical worsening in spite of adequate psychotropic treatment. To our knowledge, this is the first description of catatonia associated with HE.
