States of Mind with Respect to Attachment: a comparative study between women who killed their children and mothers diagnosed with post-partum depression.

INTRODUCTION: Attachment theory has been linked with the caregiving system, acting as a drive for a mother's behavior towards her offspring. The most dramatic consequence of distress following maternity is filicide. Despite this, only few studies addressed the attachment models of women who committed filicide, and very little provided comparisons with mothers diagnosed with post-partum depression. OBJECTIVE: We described the socio-demographic and psychopathological characteristics of mothers who committed filicide. Our aim was to detect differences in the attachment models between mothers who committed filicide, mothers with post-partum depression and control mothers. Participants and setting: We recruited 19 women who committed filicide (group F) along with 52 women with post-partum depression (group D), and 23 control mothers (group C). METHODS: We administered a semi-structured interview on socio-demographic aspects and psychiatric history along with the Adult Attachment Interview. We performed an ANOVA, a post-hoc analysis and a logistic regression. RESULTS: The logistic regression showed a higher prevalence of Dismissing and Disorganized attachments in women of group F compared with group C (p = 0.002, p = 0.007). Dismissing attachment was also overrepresented in group D vs group C (p = 0.012). Interestingly, women of group F showed a Preoccupied/entangled attachment to a lesser extent than those of group D, reaching a borderline significance (p = 0.056). CONCLUSIONS: Disorganized and Dismissing models of attachment are prevalent in women who committed filicide compared with mothers with post-partum depression and controls, while other models of attachment are less frequent. Therefore, attachment could be taken into consideration to define the risk for committing filicide.

Personality structure and attachment models of women who kill their children. A systematic review on maternal filicide.

BACKGROUND: A mother's ability to attune with her child is crucial in structuring one's attachment style and personality. Both dimensions shape mother-child interactions, and they are therefore likely to impact on the risk of filicide. Numerous risk factors for filicide have been identified, but personality and attachment look relatively understudied. OBJECTIVE: We focused on filicide mothers' personality and states of mind regarding attachment to shed new light on this phenomenon, for the purpose of an improved and earlier identification of at-risk maternities. METHODS: A systematic review of five electronic databases was performed. All studies on filicide, infanticide or neonaticide were included in the search, regardless of the study design or the socio-demographic characteristics of the offenders. RESULTS: Twelve original articles were found to be eligible for the systematic review. The data were categorized in personality and attachment related, and then by study design. Only two studies performed comparisons with control groups, and only three reported data about psychodiagnostic/neuropsychiatric tests or questionnaires. Personality diagnoses were strongly heterogeneous (mostly pertaining to cluster B and C), and not supported by statistically significant evidence. Attachment was examined by only one study, which showed that the most frequent states of mind regarding attachment were unresolved/unclassifiable (U/CC). CONCLUSIONS: Despite their pivotal importance in determining relational patterns in an individual, both personality and attachment are almost unacknowledged across the literature about maternal filicide. It is thus advisable to further focus on them, carrying out structured and validated assessments, to better define the causes of this dramatic event.

Social cognition deficit and genetic vulnerability to schizophrenia in 22q11 deletion syndrome.

INTRODUCTION: 22q11.2 microdeletion syndrome (22q11DS) is associated with a 25% risk of psychotic onset. MATERIALS AND METHODS: The sample consist of 120 subjects: 39 schizophrenics (SCZ); 20 siblings of schizophrenic patients (SIB); 34 22q11DS non-psychotic patients (DEL); 17 22q11DS psychotic patients (DEL_scz); 30 control subjects (CS). Social cognition was evaluated with the awareness of social interference test. Intelligence Quotient (IQ) was calculated with Wechsler Adult Intelligence Scale. TASIT (Awareness of Social Inference Test) performance was analyzed via MANOVA, including IQ as covariate. RESULTS: Group and IQ showed significant effect (p < 0.001; p = 0.037). The only TASIT variables where IQ showed no effect were paradoxical sarcasm; sincerity; lie. In sincerity, CS group shows a better performance than both 22q11DS groups (p < 0.05). In paradoxical sarcasm and lie, CS group performed better than each clinical group (p < 0.05). Regarding lie, DEL group was worst also respect to SCZ group (p = 0.029). CONCLUSIONS: Our results show a specific social cognition deficit in 22q11DS and schizophrenia.

Systematic review and multi-modal meta-analysis of magnetic resonance imaging findings in 22q11.2 deletion syndrome: Is more evidence needed?

22q11.2 deletion syndrome (DS) is considered to be the most robust genetic model of psychosis. In the last decade, there has been increased interest in the brain abnormalities associated with these genetic changes. Most imaging findings in this population come from small samples. This increases the risk of reporting spurious effects that reflect the idiosyncrasies of each study. Thus, the current work is aimed at identifying whether there are spatially consistent structural and functional brain abnormalities in individuals with 22q11.2 DS through (i) a comprehensive label-based systematic review and (ii) a coordinate-based meta-analysis of magnetic resonance imaging studies. The systematic review identified the frontal middle gyri, posterior cingulum, right cuneus and bilateral precuneus as the most affected regions. The meta-analysis revealed consistent abnormalities in the bilateral inferior parietal lobe, right precuneus, right superior temporal gyrus and posterior cingulate cortex. This study provides an important starting point for future research as it sheds light on possible genetically determined psychosis susceptibility regions.

Genetic and clinical features of social cognition in 22q11.2 deletion syndrome.

22q11.2 deletion syndrome (22q11.2 DS) is widely known as one of the most compelling genetic models of schizophrenia so far, being almost 40% of the carriers affected by psychotic symptoms. Moreover, most of these subjects also show impairment in social cognition, which is a comprehensive array of function that guides social interaction with the others, leading as well to the acquisition of new cognitive and social skills. In the last decade researchers have argued whether social cognition dysfunctions could be underlined by specific genetic alterations, and whether these are linked to specific clinical features. Some valid candidate genes are RTN4R, that encodes a protein which inhibits axonal sprouting, DGCR8, crucial in mRNA processing, or catechol-O-methyltransferase (COMT) and proline oxydase 1 (PRODH), involved in catecholamine metabolism in frontal cortex. This is the first article to address the topic of social cognition in 22q11.2 DS from a wide perspective, with a highlight on its genetic characteristics. We will provide a narrative review of the most recent findings and we will point out new directions on this research path, in order to achieve an effective characterization of the neurobiological system underlying social behavior.

Coping strategies in individuals at ultra-high risk of psychosis: A systematic review.

AIM: The impact of dysfunctional coping strategies during the prodromal phase of psychosis has recently been explored by several studies. What has yet to be clarified is whether maladaptive coping is evident in the prodromal phase and the impact that this might have on symptomatic and functional outcomes. The aim of this study was to review the findings on coping in individuals at ultra-high risk of psychosis (UHR) in relation to symptoms and level of functioning. METHODS: Original articles were identified by searching 7 databases using the terms "prodrom*," "ultra high risk," "clinical high risk," "at-risk mental state," "coping style*," "coping strategies," "cope," "coping" and "psychosis". We included original articles that: (1) reported a measure of coping and (2) evaluated UHR individuals. RESULTS: A total of 9 original articles of 335 that examined coping in individuals at high risk of psychosis were included. UHR subjects were more likely to use maladaptive coping strategies than healthy controls and were more likely to use emotion-focussed than task-oriented coping. Maladaptive coping was associated with higher levels of negative symptoms, whereas positive coping was associated with fewer negative symptoms. The coping style employed by UHR individuals was found to negatively influence their psychosocial functioning. CONCLUSIONS: It is still unclear whether coping heightens or reduces the likelihood of transition to psychosis in relation to other factors, including environment. Longitudinal studies could clarify whether coping styles remain stable after the onset of psychosis or whether the emerging psychotic symptoms influence the coping strategies.

Attentional functioning in individuals with 22q11 deletion syndrome: insight from ERPs.

The 22q11 deletion syndrome (22q11DS), or DiGeorge syndrome (DG), is one of the most common genetic deletion syndromes. DG also carries a high risk for psychiatric disorders, with learning disabilities frequently being reported. Impairments in specific cognitive domains, such as executive functioning and attention, have also been described. The aim of this study was to investigate attentional functioning in a group of subjects with DG using ERPs, and in particular the P300 and CNV components. We studied ten patients with DG and ten healthy subjects that performed a P300 Novelty task and a CNV motor task. P3b amplitude was significantly lower in patients than in controls, while P3b latency was comparable in patients and controls. The P3a parameters were similar in both groups. All CNV amplitudes were significantly lower in DG patients than in controls. DG patients displayed slower reaction times in the CNV motor task than healthy subjects. These results point to a cognitive dysfunction related above all to executive attentional processing in DG patients. In particular, a specific difficulty emerged in selective attention and in the ability to orient and to sustain the anticipatory attention required for an executive motor response.
