Development of symptoms of oppositional defiant disorder from preschool to adolescence: the role of bullying victimization and emotion regulation.

BACKGROUND: Childhood oppositional defiant disorder (ODD) is associated with adverse outcomes which can continue to impair life well into adulthood. Identifying modifiable etiological factors of ODD is therefore essential. Although bullying victimization and poor emotion regulation are assumed to be risk factors for the development of ODD symptoms, little research has been conducted to test this possibility. METHODS: A sample (n = 1,042) from two birth cohorts of children in the city of Trondheim, Norway, was assessed biennially from age 4 to 14 years. Parents and children (from age 8) were assessed with clinical interviews to determine symptoms of ODD, children reported on their victimization from bullying, and teachers reported on children's emotion regulation. RESULTS: Oppositional defiant disorder symptoms increased from age 4 to 6, from age 8 to 10, and then started to wane as children entered adolescence. A Random Intercept Cross-Lagged Panel Model revealed that increased emotion regulation predicted a reduced number of ODD symptoms across development (ß = -.15 to -.13, p < .001). This prediction was equally strong for the angry/irritable and argumentative/defiant dimensions of ODD. No longitudinal links were observed between bullying victimization and ODD symptoms. CONCLUSIONS: Improving emotion regulation skills may protect against ODD symptoms throughout childhood and adolescence.

From vision to cognition: potential contributions of cerebral visual impairment to neurodevelopmental disorders.

Vision has a crucial role to play in human development and functioning. It is, therefore, not surprising that vision plays a fundamental role in the development of the child. As a consequence, an alteration in visual function is, therefore, likely to hinder the child's development. Although ocular disorders are well known, diagnosed and taken into account, cerebral visual impairments (CVI) resulting from post-chiasmatic damage are largely underdiagnosed. However, among the disorders resulting from an episode of perinatal asphyxia and/or associated with prematurity, or neonatal hypoglycaemia, CVIs are prominent. In this article, we focus on the role of the possible effects of CVI on a child's learning abilities, leading to major difficulty in disentangling the consequences of CVI from other neurodevelopmental disorders (NDD) such as dyslexia, dyscalculia, dysgraphia, attention-deficit/hyperactivity disorder (ADHD), developmental coordination disorder (DCD) and autism spectrum disorders (ASD). Although we focus here on the possible overlap between children with CVI and children with other NDD, De Witt et al. (Wit et al. Ear Hear 39:1-19, 2018) have raised exactly the same question regarding children with auditory processing disorders (the equivalent of CVI in the auditory modality). We underline how motor, social and cognitive development as well as academic success can be impaired by CVI and raise the question of the need for systematic evaluation for disorders of vision, visual perception and cognition in all children presenting with a NDD and/or previously born under adverse neurological conditions.

Novel Oppositional Defiant Disorder 12 Months After Traumatic Brain Injury in Children and Adolescents.

OBJECTIVE: The investigators examined the factors predictive of novel oppositional defiant disorder in the 6-12 months following traumatic brain injury (TBI). METHODS: Children ages 5-14 years old who experienced a TBI were recruited from consecutive admissions to five hospitals. Participants were evaluated soon after injury (baseline) for preinjury characteristics, including psychiatric disorders, adaptive function, family function, psychosocial adversity, family psychiatric history, socioeconomic status, and injury severity, to develop a biopsychosocial predictive model for development of novel oppositional defiant disorder. MRI analyses were conducted to examine potential brain lesions. Psychiatric outcome, including that of novel oppositional defiant disorder, was assessed 12 months after injury. RESULTS: Although 177 children were recruited for the study, 120 children without preinjury oppositional defiant disorder, conduct disorder, or disruptive behavior disorder not otherwise specified (DBD NOS) returned for the 12-month assessment. Of these 120 children, seven (5.8%) exhibited novel oppositional defiant disorder, and none developed conduct disorder or DBD NOS in the 6-12 months postinjury. Novel oppositional defiant disorder was significantly associated with lower socioeconomic status, higher psychosocial adversity, and lower preinjury adaptive functioning. CONCLUSIONS: These results demonstrate that novel oppositional defiant disorder following TBI selectively and negatively affects an identifiable group of children. Both proximal (preinjury adaptive function) and distal (socioeconomic status and psychosocial adversity) psychosocial variables significantly increase risk for this outcome.

Novel Oppositional Defiant Disorder 6 Months After Traumatic Brain Injury in Children and Adolescents.

OBJECTIVE: The investigators aimed to assess predictive factors of novel oppositional defiant disorder (ODD) among children and adolescents in the first 6 months following traumatic brain injury (TBI). METHODS: Children ages 5-14 years who experienced a TBI were recruited from consecutive admissions to five hospitals. Testing of a biopsychosocial model that may elucidate the development of novel ODD included assessment soon after injury (baseline) of preinjury characteristics, including psychiatric disorders, adaptive function, family function, psychosocial adversity, family psychiatric history, socioeconomic status, injury severity, and postinjury processing speed (which may be a proxy for brain injury). MRI analyses were also conducted to examine potential brain lesions. Psychiatric outcome, including that of novel ODD, was assessed 6 months after the injury. RESULTS: A total of 177 children and adolescents were recruited for the study, and 134 who were without preinjury ODD, conduct disorder, or disruptive behavior disorder not otherwise specified (DBD NOS) returned for the 6-month assessment. Of those who returned 6 months postinjury, 11 (8.2%) developed novel ODD, and none developed novel conduct disorder or DBD NOS. Novel ODD was significantly associated with socioeconomic status, preinjury family functioning, psychosocial adversity, and processing speed. CONCLUSIONS: These findings show that an important minority of children with TBI developed ODD. Psychosocial and injury-related variables, including socioeconomic status, lower family function, psychosocial adversity, and processing speed, significantly increase risk for this outcome.

Oxytocin: at birth and beyond. A systematic review of the long-term effects of peripartum oxytocin.

Oxytocin is one of the most commonly used medications during labour and delivery. Recent insights from basic neuroscience research suggest that the uterotonic effects of oxytocin may arguably be trivial when compared with its profound effects on higher-order human behaviour. The purpose of this review is to highlight the potential consequences of manipulating oxytocinergic signalling during the peripartum period and its long-term impact on the maternal-infant dyad. We identified four domains where modulation of oxytocinergic signalling might be consequential: postpartum depression; breastfeeding; neurodevelopment; and chronic pain, and performed a literature search to address the impact of peripartum oxytocin administration. We have shown modest, but inconsistent, evidence linking peripartum oxytocin administration with postpartum depression. Breastfeeding success appeared to be negatively correlated with peripartum oxytocin exposure, perhaps secondary to impaired primitive neonatal reflexes and maternal-infant bonding. The association between perinatal oxytocin exposure and subsequent development of neurodevelopmental disorders such as autism in the offspring was weak, but these studies were limited by the lack of information on the cumulative dose. Finally, we identified substantial evidence for analgesic and anti-hypersensitivity effects of oxytocin which might partly explain the low incidence of chronic pain after caesarean birth. Although most data presented here are observational, our review points to a compelling need for robust clinical studies to better dissect the impact of peripartum oxytocin administration, and as stewards of its use, increase the precision with which we administer oxytocin to prevent overuse of the drug.

The relationship between allergic diseases and internalising and externalising behaviours in Spanish children: A cross-sectional study.

INTRODUCTION AND OBJECTIVES: The relationship between allergic diseases and behavioural disorders is still unclear. The objective of this study was to describe and compare children's behaviour (internalising and externalising) across a sample of children aged 6-11 years with and without allergic diseases. MATERIALS AND METHODS: This was a cross-sectional observational case-control study. A survey to 366 families (194 allergic cases and 172 controls), including a child behaviour checklist (CBCL) and a socio-demographic questionnaire with questions related to family, school education, health conditions and allergy symptoms, was administered. RESULTS: Children with a diagnosis of allergy showed higher scores in the overall CBCL score (standardised mean differences [SMD] = 0.47; confidence intervals [CI]: 0.26-0.68) and in the internalising and externalising factors (SMD = 0.52 and SMD = 0.36, respectively) than non-allergic children. Odds ratio (OR) analyses showed a higher risk (OR = 2.76; 95% CI [1.61 to 4.72]) of developing a behavioural difficulty in children diagnosed with allergies. Age and level of asthma appear as modulatory variables. CONCLUSIONS: Children aged 6-11 years diagnosed with allergies showed larger behavioural problems than non-allergic children, especially in the case of internalising behaviours. These findings suggest the importance of attending to them and treating them in the early stages of diagnosis to avoid future psychological disorders.

Psychiatric Disorders in the Adolescent Offspring of Mothers with Thyroid Problems During Pregnancy.

Maternal thyroid problems during pregnancy have been linked to neurocognitive impairments in children. While studies suggest that disorders of maternal thyroid function during pregnancy are associated with symptoms of mental health problems in children, little is known about the risk of clinically significant psychiatric disorders in adolescence. A sample of 2451 Canadian adolescents enrolled in the Ontario Child Health Study completed the Mini International Neuropsychiatric Interview for Children and Adolescents at 12-17 years of age. Their mothers self-reported thyroid problems during pregnancy. Gestational thyroid problems were associated with offspring oppositional defiant disorder (ODD; OR 3.73; 95% CI 1.69-8.24), conduct disorder (CD; OR 12.95; 95% CI 5.12-32.75), and social anxiety disorder (SAD; OR 6.25; 95% CI 2.53-15.47). Neither sex nor gestational age moderated associations between prenatal thyroid dysfunction and the majority of outcomes. School performance mediated 8% of the association between thyroid problems and SAD, 21% for CD and 53% for ODD.

Six-Month Follow-up of the Families on Track Intervention Pilot Trial for Children With Fetal Alcohol Spectrum Disorders and Their Families.

BACKGROUND: When the primary disabilities associated with fetal alcohol spectrum disorders (FASD) are not well supported, individuals are at higher risk for mental health problems and other secondary conditions. The Families on Track (FOT) intervention was designed to prevent secondary conditions and improve family functioning in children with FASD. Promising results from a pilot study demonstrated positive effects on child and caregiver outcomes immediately following the intervention. The objective of this study was to examine the sustainability of these effects 6 months postintervention. METHODS: Thirty children (ages 4 to 8) with prenatal alcohol exposure and their caregivers were enrolled in the original study. Families were randomized to the FOT intervention or an active comparison group that provided comprehensive assessment and individualized feedback. The intervention integrated a positive parenting curriculum and a child skills group. Families were assessed at baseline, postintervention, and 6-month follow-up visits. Follow-up data were available for 24 families on child and caregiver outcomes. Data were analyzed using effect size calculations and analysis-of-variance techniques. RESULTS: Relative to the comparison group, intervention families showed continued gains in parenting efficacy and maintained prior improvements in FASD knowledge over the follow-up period. Although intervention families reported a decrease in their needs being met over the follow-up period, they continued to report their needs being met to greater extent than those in the comparison group. Consistent with postintervention outcomes, children in both groups exhibited similar decreases in child disruptive behavior 6 months following the intervention. Unfortunately, positive gains seen at postintervention for child self-esteem and emotion regulation were attenuated at follow-up. CONCLUSIONS: This pilot study yielded promising effects on important areas of caregiver functioning. However, the intervention's impact on child functioning waned over time, suggesting the need for sustained or alternate child intervention.

Attachment and reflective functioning in children with somatic symptom disorders and disruptive behavior disorders.

Our goal in conducting this study was to examine whether children with somatic symptom disorders (SSD) and disruptive behavior disorders (DBD) have higher rates of insecure or disorganized attachment and difficulties in mentalizing (operationalized as reflective functioning) as compared to a control group. Participants were 131 children (8-15 years) spanning two groups-a clinical group (n = 85), comprised of children fitting the criteria of our target diagnostic classifications (SSD: N = 45; DBD: N = 40), as well as a comparison group of healthy control children (n = 46). Children completed the Child Attachment Interview, which was later coded by reliable raters for attachment security and reflective functioning (RF). Consistent with our predictions, children in the clinical group had significantly lower RF and were significantly more likely to have insecure (over 80%) and disorganized attachment (over 40%) than children in the comparison group. In addition, RF was significantly lower in children with DBD than children with SSD. Furthermore, in the SSD group, children's RF regarding self was significantly lower than RF regarding others. Finally, consistent with prior studies, RF and attachment were associated. The findings indicate that school-aged children with SSD and DBD have higher rates of insecure and disorganized attachment. Consistent with theory, RF and attachment were loosely coupled, but RF alone differentiated among the diagnostic subgroups. Implications for treatment and prevention are discussed.

Prenatal exposure to very severe maternal obesity is associated with adverse neuropsychiatric outcomes in children.

BACKGROUND: Prenatal maternal obesity has been linked to adverse childhood neuropsychiatric outcomes, including increased symptoms of attention deficit hyperactivity disorder (ADHD), internalizing and externalizing problems, affective disorders and neurodevelopmental problems but few studies have studied neuropsychiatric outcomes among offspring born to very severely obese women or assessed potential familial confounding by maternal psychological distress. METHOD: We evaluated neuropsychiatric symptoms in 112 children aged 3-5 years whose mothers had participated in a longitudinal study of obesity in pregnancy (50 very severe obesity, BMI ⩾40 kg/m2, obese class III and 62 lean, BMI 18.5-25 kg/m2). The mothers completed the Conners' Hyperactivity Scale, Early Symptomatic Syndrome Eliciting Neurodevelopmental Clinical Examination Questionnaire (ESSENCE-Q), Child's Sleep Habits Questionnaire (CSHQ), Strengths and Difficulties Questionnaire (SDQ), and Child Behavior Checklist (CBCL) to assess child neuropsychiatric symptoms. Covariates included child's sex, age, birthweight, gestational age, socioeconomic deprivation levels, maternal age, parity, smoking status during pregnancy, gestational diabetes and maternal concurrent symptoms of anxiety and depression assessed using State Anxiety of Spielberger State-Trait Anxiety Index (STAI) and General Health Questionnaire (GHQ), respectively. RESULTS: Children exposed to prenatal maternal very severe obesity had significantly higher scores in the Conners' Hyperactivity Scale; ESSENCE-Q; total sleep problems in CSHQ; hyperactivity, conduct problems and total difficulties scales of the SDQ; higher externalizing and total problems, anxious/depressed, aggressive behaviour and other problem syndrome scores and higher DSM-oriented affective, anxiety and ADHD problems in CBCL. Prenatal maternal very severe obesity remained a significant predictor of child neuropsychiatric problems across multiple scales independent of demographic factors, prenatal factors and maternal concurrent symptoms of anxiety and depression. CONCLUSIONS: Prenatal maternal very severe obesity is a strong predictor of increased neuropsychiatric problems in early childhood.

Maternal pre-pregnancy obesity and neuropsychological development in pre-school children: a prospective cohort study.

BackgroundMaternal pre-pregnancy obesity may impair infant neuropsychological development, but it is unclear whether intrauterine or confounding factors drive this association.MethodsWe assessed whether maternal pre-pregnancy obesity was associated with neuropsychological development in 1,827 Spanish children. At 5 years, cognitive and psychomotor development was assessed using McCarthy Scales of Children's Abilities, attention deficit hyperactivity disorder (ADHD) symptoms using the Criteria of Diagnostic and Statistical Manual of Mental Disorders, and autism spectrum disorder symptoms using the Childhood Asperger Syndrome Test. Models were adjusted for sociodemographic factors and maternal intelligence quotient. We used paternal obesity as negative control exposure as it involves the same source of confounding than maternal obesity.ResultsThe percentage of obese mothers and fathers was 8% and 12%, respectively. In unadjusted models, children of obese mothers had lower scores than children of normal weight mothers in all McCarthy subscales. After adjustment, only the verbal subscale remained statistically significantly reduced (ß: -2.8; 95% confidence interval: -5.3, -0.2). No associations were observed among obese fathers. Maternal and paternal obesity were associated with an increase in ADHD-related symptoms. Parental obesity was not associated with autism symptoms.ConclusionMaternal pre-pregnancy obesity was associated with a reduction in offspring verbal scores at pre-school age.

Trait Impulsivity and the Externalizing Spectrum.

This article reviews evidence that trait impulsivity-expressed early in life as the hyperactive-impulsive and combined presentations of attention-deficit/hyperactivity disorder (ADHD)-is a bottom-up, subcortically mediated vulnerability to all externalizing disorders. This vulnerability arises from deficient mesolimbic dopamine responding, which imbues psychological states (irritability, discontentment) that motivate excessive approach behavior (hyperactivity, impulsivity). Through complex interactions with (a) aversive motivational states that arise from largely independent subcortical systems, (b) emotion regulatory mechanisms that arise from top-down, cortical modulation of subcortical neural function, and (c) environmental risk factors that shape and maintain emotion dysregulation, trait impulsivity confers vulnerability to increasingly severe externalizing behaviors across development. This perspective highlights the importance of identifying transdiagnostic neural vulnerabilities to psychopathology; dovetails with the hierarchical, latent structure of psychopathology; and suggests that progression along the externalizing spectrum is an ontogenic process whereby a common, multifactorially inherited trait interacts with endogenous and exogenous influences to yield increasingly intractable externalizing behaviors across development.

Problem behaviour and psychosocial functioning in young children with Williams syndrome: parent and teacher perspectives.

BACKGROUND: There is sparse literature about problem behaviour in young children with Williams syndrome (WS) and little consideration of the perspectives of multiple respondents. METHODS: Problem behaviour of 35 children with WS ages 2 to 6 was examined based on both parent and teacher report using the Achenbach preschool forms. RESULTS: The most prominent areas of difficulty based on both parent and teacher report were attention problems, pervasive developmental problems and emotion reactivity difficulties. Some rater differences were observed; most notably, teachers reported more externalising behaviour problems including more aggressive behaviour, Attention Deficit/Hyperactivity problems and Oppositional Defiant problems than did parents. Few relations to intellectual functioning, age or gender were observed. DISCUSSION: Some aspects of problem behaviour evident in older children (e.g. attention problems, social problems) are also apparent for young children with WS, while other areas are less prominent (e.g. anxiety). The implications of the findings for understanding the behavioural phenotype associated with WS are discussed.

Risk factors for comorbid oppositional defiant disorder in attention-deficit/hyperactivity disorder.

Oppositional defiant disorder (ODD) is highly prevalent in attention-deficit/hyperactivity disorder (ADHD). Individuals with both ADHD and ODD (ADHD + ODD) show a considerably worse prognosis compared with individuals with either ADHD or ODD. Therefore, identification of risk factors for ADHD + ODD is essential and may contribute to the development of (early) preventive interventions. Participants were matched for age, gender, and ADHD-subtype (diagnostic groups), and did not differ in IQ. Predictors included pre- and perinatal risk factors (pregnancy duration, birth weight, maternal smoking during pregnancy), transgenerational factors (parental ADHD; parental warmth and criticism in diagnostic groups), and postnatal risk factors (parental socioeconomic status [SES], adverse life events, deviant peer affiliation). Three models were assessed, investigating risk factors for ADHD-only versus controls (N = 86), ADHD + ODD versus controls (N = 86), and ADHD + ODD versus ADHD-only (N = 90). Adverse life events and parental ADHD were risk factors for both ADHD + ODD and ADHD-only, and more adverse life events were an even stronger risk factor for comorbid ODD compared with ADHD-only. For ADHD + ODD, but not ADHD-only, parental criticism, deviant peer affiliation, and parental SES acted as risk factors. Maternal smoking during pregnancy acted as minor risk factor for ADHD-only, while higher birth weight acted as minor risk factor for ADHD + ODD. No effects of age were present. Findings emphasise the importance of these factors in the development of comorbid ODD. The identified risk factors may prove to be essential in preventive interventions for comorbid ODD in ADHD, highlighting the need for parent-focused interventions to take these factors into account.

The Treatment of Disruptive Vocalization in Dementia (Behavioral and Psychological Symptoms of Dementia) With Electroconvulsive Therapy: A Case Series.

OBJECTIVE: There is emerging evidence that electroconvulsive therapy (ECT) can help with the behavioral and psychological symptoms of dementia. One of the most distressing behavioral symptoms of dementia is disruptive vocalization. Previous small case series have suggested that antidepressants and ECT can be beneficial for this distressing condition. The aim of this study was to describe the successful use of ECT in treating 5 patients with disruptive vocalization. METHODS: A retrospective chart review of 5 patients with dementia of mixed etiologies was conducted comparing pretreatment and posttreatment scores on the Cohen-Mansfield Agitation Inventory. All 5 patients had unsuccessful treatments with nonpharmacological methods and pharmacotherapy including antidepressants. RESULTS: After completion of a series of ECT, the mean verbal agitation score decreased from 6.8 (95% confidence interval, 6.3-7.3) to 2.3 (95% confidence interval, 1.3-3.3), with both clinical and statistical significance (P < 0.001). CONCLUSIONS: Although further research is needed, these findings support considering the use of ECT for disruptive vocalization in dementia.

[Pre- and perinatal risk factors in autism spectrum disorder and attention deficit/hyperactivity disorder]. / Prä- und perinatale Risikofaktoren bei Autismus-Spektrum-Störung und Aktivitäts- und Aufmerksamkeitsstörung.

Objective: Epidemiological studies indicate the relevance of pre- and perinatal risk factors for the genesis of attention deficit/hyperactivity disorder and autism spectrum disorder. This study compares potential risk factors in a clinical sample of children with ADHD, ASD, the combination of both diseases, ADHD and oppositional defiant or conduct disorder (ADHD & ODD/CD) and examined whether the existence of additional risk factors promotes the occurrence of combined diseases. Method: We compared the pre- and perinatal risk factors of 341 patients (299 boys, 42 girls) from a clinical population, differentiating between children with ADHD (n=80), ASD (n=122), ADHD & ASD (n=55), or ADHD & ODD/CD (n=84). Results: We observed a higher rate of maternal smoking, a higher rate of migration, and lower parental education among the children with ADHD & ODD/CD compared to those with ASD or ADHD. The rate of migration background was higher among the children with ASD compared to children with ADHD. Miscarriage was a specific risk factor for ADHD & ASD. Conclusion: Numerous risk factors described in epidemiological studies occurred only rarely in our clinical sample. The distribution of most risk factors was comparable between the examined diseases.

Emotional and behavioural problems in young children with autism spectrum disorder.

AIM: To assess the frequency, pervasiveness, associated features, and persistence of emotional and behavioural problems in a community sample of young children with autism spectrum disorder (ASD). METHOD: Parents (n=277) and teachers (n=228) of 4- to 8-year-olds completed the Developmental Behaviour Checklist (DBC). Intellectual ability and autism symptomatology were also assessed. A subsample repeated the DBC. RESULTS: Three-quarters of the cohort scored above the clinical cut-off on the Developmental Behaviour Checklist Primary Carer Version (DBC-P) questionnaire; almost two-thirds of these scored above cut-off on the Developmental Behaviour Checklist Teacher Version (DBC-T) questionnaire. In 81%, problems persisted above threshold 14 months later. Higher DBC-P scores were associated with greater autism symptomatology, higher deprivation index, parental unemployment, and more children in the home but not with parental education or ethnicity, or child's age or sex. Children with IQ>70 scored higher for disruptive behaviour, depression, and anxiety symptoms; those with IQ<70 scored higher for self-absorption and hyperactivity. INTERPRETATION: The DBC identifies a range of additional behaviour problems that are common in ASD and which could be the focus for specific intervention. The results highlight the potential benefit of systematic screening for co-existing problems.

Neurodevelopmental, emotional, and behavioural problems in Duchenne muscular dystrophy in relation to underlying dystrophin gene mutations.

AIM: Duchenne muscular dystrophy (DMD) is associated with neuropsychiatric disorders. The aim of the study was to characterize the DMD neuropsychiatric profile fully and to explore underlying genotype/phenotype associations. METHOD: One hundred and thirty males with DMD (mean age 9y 10mo, range 5-17y) in four European centres were included and completed IQ assessment and a neurodevelopmental-screening questionnaire. Of these, 87 underwent comprehensive neuropsychiatric assessment using structured diagnostic interview and parent-reported questionnaires. RESULTS: The overall mean score on the neurodevelopmental questionnaire was significantly abnormal compared with the general population of children (p<0.001). On average, intelligence was below the population mean, with intellectual disability observed in 34 males (26%). Autistic spectrum disorder was identified in 18 (21%), hyperactivity in 21 (24%), and inattention in 38 (44%). Clinical levels of internalizing and externalizing problems were observed in 21 (24%) and 13 (15%) respectively. Over a third of males scored more than two measures of emotional, behavioural, or neurodevelopmental problems. Males with mutations at the 3' end of the DMD gene affecting all protein isoforms had higher rates of intellectual disability and clusters of symptoms. INTERPRETATION: Males with DMD are at very high risk of neuropsychiatric disturbance, and this risk appears to increase with mutations at the 3' end of the gene. Patterns of symptom clusters suggest a DMD neuropsychiatric syndrome, which may require prompt evaluation and early intervention.

Behavioural But Not Cognitive Impairment Is a Determinant of Caregiver Burden in Amyotrophic Lateral Sclerosis.

BACKGROUND: Caregivers of patients affected by amyotrophic lateral sclerosis (ALS) are involved with great determination in the treatment process since the earliest stages of the disease with an increasing burden to be of help to the ailing persons. AIM: To test separately the impact of ALS patients' cognitive and behavioural impairments on caregiver burden and mood status in 84 outpatient/main caregiver couples. DESIGN: Patients were tested with the ALS-Cognitive Behavioural Screen (ALSCBS-ci and -bi), Frontal Assessment Battery, Weigl's Sorting Test, Mini-Mental State Examination, Beck's Depression Inventory (BDI). Analogously, caregivers completed the BDI and Caregiver Burden Inventory (CBI). RESULTS: CBI correlated with ALSCBS-bi, besides ALSFRS-R, disease progression index and caregiver BDI. Caregiver BDI also correlated with ALSCBS-bi scores. No correlations were found with cognitive tests. The correlation between CBI and the ALSCBS-bi score was specifically sustained by the social burden sub-domain of CBI. CONCLUSIONS: As previously reported using other tools, behavioural impairment is a determinant of burden and mood in ALS caregivers. Conversely, cognitive impairment fails to emerge as a major target when aiming at easing the increasing burden or improving mood in ALS caregivers.

[Psychopathology related to women pubertal precocity]. / Psychopathologie associée aux précocités pubertaires féminines.

INTRODUCTION: Puberty is a developmental process characterized by hormonal and physical changes leading to the ability of reproduction. Precocious puberty, especially in girls, has been associated with an increased incidence of emotional and behavioral problems. Adolescence is a life stage influenced both by the biological changes of puberty and the emergence of new social challenges. In individuals facing these developmental issues at a younger age than expected, the exposure to internal and external stress factors may be greater than in other young people. METHODS: This narrative review provides an overview of psychopathology associated with precocious puberty in order to raise awareness of clinicians dealing with adolescents at risk for adverse behavioral and emotional outcomes. Developmental challenges of standard puberty and adolescence will be outlined before a more detailed description of recent findings from clinical and epidemiological studies. Putative mechanisms underlying the association between precocious puberty and psychopathology will also be discussed. RESULTS: Epidemiological studies have shown that an early onset of puberty in girls is associated with an earlier onset of sexuality, an earlier age of first birth and a lesser professional qualification regardless of cognitive abilities and socio-economic status. In both population studies and clinical cohorts, girls with an early age of puberty or in treatment for precocious puberty have more disruptive behavior disorders such as conduct disorders, more substance abuse disorders and delinquent behavior compared to their standard developing peers. Precocious puberty and behavioral problems may have common genetic and environmental risk factors. In young people with conduct disorders and early puberty, findings have emphasized the role of non-shared environmental factors. Low birth weight, obesity, exposure to endocrine-disrupting chemicals and adoption are potentially shared between both conditions. Early puberty in girls is also associated with psychosocial stressors and at-risk environments. The early development of secondary sexual characteristics in girls attracts older and more deviant peers, raising probability of sexual contacts but also of drug use and of a disengagement in school activities. Adolescence is the life stage during which prevalence of depressive disorders rises significantly, especially in girls. Hormonal changes and increase of the Body Mass Index leading to dissatisfaction with body image, have been put forward to explain this trend. Psychosocial challenges (emerging sexuality, instability of identity and social role) are other sources of stress at this particular period of life characterized by emotional hyper-reactivity. These stressors may have greater impact in young people showing a discrepancy between physical and affective maturation. Follow-up studies have shown that emotional and behavioral problems tend to lessen with time. Nevertheless, a heightened risk of depressive disorder remains in girls having had an early onset of puberty when other risk factors co-exist. CONCLUSION: Early puberty, especially in girls, has been associated with a number of emotional and behavioral symptoms and difficulties in adaptive functioning. Even though these adverse outcomes seem to lessen with time, heightened risk for depression and negative impact on socio-professional outcomes persist in subjects with other risk factors. The impact of treatment of precocious puberty on psycho-behavioral outcomes is currently unknown. However, clinicians should be aware that the social and emotional challenges these adolescents with atypical pubertal development have to face put them at risk for psychopathology and are potentially accessible to preventive actions.
