Impulsivity in adolescents with major depressive disorder: A comparative tunisian study.

BACKGROUND: The association between impulsivity and depressive disorders in adolescence has been little studied at the literature and in our country, yet impulsivity is a major risk factor for suicide. Thus we aimed on this study to evaluate impulsivity in 25 adolescents with Major Depressive Disorder MDD compared to a control sample and to analyze the correlations between impulsivity and clinical features of MDD. METHODS: Employing a matched case-control design, participants included 25 adolescents with MDD and 75 controls. We have administered the Barratt Impulsivity Scale BIS-11 for the two groups to evaluate impulsivity. Semi structured interviews according DSM 5 criteria were conducted for adolescents with MDD. The Child Depressive Inventory CDI was used to measure depressive symptoms in the control sample. RESULTS: Adolescents with MDD were more impulsive compared to controls according to the BIS-11 in its three domains: motor (24.96±6.26 against 20.6±4.84; p=0.000), attentional (20.88±5.03 against 16.64±3.2; p=0.000) and non planning (28.2±7.26 against 24.44±4.32; p=0.02). Impulsivity was not correlated with clinical features of MDD (suicide attempts, psychiatric comorbidities, antidepressant medication …). CONCLUSION: Adolescents with MDD seem to be more impulsive than control subjects regardless their clinical features. Whether it is a specific characteristic or a symptom among others of MDD, impulsivity predicts health-related behaviors and associated damage that need to be detected and prevented in time.

Prenatal, perinatal and postnatal factors associated with autism spectrum disorder / Fatores pré-natais, perinatais e pós-natais associados ao transtorno do espectrodo autismo

Abstract Objective: To identify prenatal, perinatal and postnatal risk factors in children with autism spectrum disorder (ASD) by comparing them to their siblings without autistic disorders. Method: The present study is cross sectional and comparative. It was conducted over a period of three months (July-September 2014). It included 101 children: 50 ASD's children diagnosed according to DSM-5 criteria and 51 unaffected siblings. The severity of ASD was assessed by the CARS. Results: Our study revealed a higher prevalence of prenatal, perinatal and postnatal factors in children with ASD in comparison with unaffected siblings. It showed also a significant association between perinatal and postnatal factors and ASD (respectively p = 0.03 and p = 0.042). In this group, perinatal factors were mainly as type of suffering acute fetal (26% of cases), long duration of delivery and prematurity (18% of cases for each factor), while postnatal factors were represented principally by respiratory infections (24%). As for parental factors, no correlation was found between advanced age of parents at the moment of the conception and ASD. Likewise, no correlation was observed between the severity of ASD and different factors. After logistic regression, the risk factors retained for autism in the final model were: male gender, prenatal urinary tract infection, acute fetal distress, difficult labor and respiratory infection. Conclusions: The present survey confirms the high prevalence of prenatal, perinatal and postnatal factors in children with ASD and suggests the intervention of some of these factors (acute fetal distress and difficult labor, among others), as determinant variables for the genesis of ASD.

Resumo Objetivo: Identificar fatores de risco pré-natal, perinatal e pós-natal em crianças com transtorno do espectro do autismo (TEA) ao compará-las com irmãos sem transtornos de autismo. Método: Estudo é transversal e comparativo. Foi conduzido em três meses (julho a setembro de 2014). Incluiu 101 crianças: 50 com TEA diagnosticadas de acordo com os critérios do DSM-5 e 51 irmãos não afetados. A gravidade do TEA foi avaliada pela Escala de Avaliação do Autismo na Infância (CARS). Resultados: Nosso estudo revelou uma prevalência maior de fatores pré-natais, perinatais e pós-natais em crianças com TEA em comparação com irmãos não afetados. Também mostrou uma associação significativa entre fatores perinatais e pós-natais e TEA (respectivamente p = 0,03 e p = 0,042). Nesse grupo, os fatores perinatais foram principalmente do tipo sofrimento fetal agudo (26% dos casos), longa duração do parto e prematuridade (18% dos casos em cada fator), ao passo que fatores pós-natais foram representados principalmente por infecções respiratórias (24%). No que diz respeito a fatores dos pais, nenhuma correlação foi encontrada entre a idade avançada dos pais no momento da concepção e o TEA. Da mesma forma, nenhuma correlação foi estabelecida entre a gravidade do TEA e fatores diferentes.Após regressão logística, os fatores de risco de autismo encontrados no modelo final foram: sexo masculino, infecção pré-natal do trato urinário, sofrimento fetal agudo, parto difícil e infecção respiratória. Conclusões: Esta pesquisa confirma a alta prevalência de fatores pré-natais, perinatais e pós-natais em crianças com TEA e sugere a intervenção de alguns desses fatores (sofrimento fetal agudo, parto difícil) como variáveis determinantes para a gênese do TEA.
