    Insomnia is a common pathology in the general population. It is estimated that 10 to 15 percent of the adult population has chronic insomnia and 25 to 35 percent have suffered occasional or transient insomnia due to stressful situations. The aim of this article is to provide a review of insomnia: causes, differential diagnosis, and different options of treatment. To that end we have made a search in Pubmed with the keywords "insomnia", "sleeplessness", "sleep disorders" and "pharmacological therapy". Insomnia evaluation includes a careful sleep history, personal and family history of mental and organic illness, and a registration of drug and medication intake. Authors agree that treatment should be based primarily on etiology, and secondarily on symptomatology

    Objetivos El objetivo de este estudio es validar la versión en castellano del ADHD-RS-IV (ADHD-RS-IV.es) en una muestra española. Métodos A partir de una muestra total de 652 niños y adolescentes (rango edad: 6-17 años; media [DE] = 11,14 [3,27] años), se incluyó a 518 pacientes con TDAH (criterios DSM-IV-TR) y a 134 controles sanos. Para la evaluación de la estructura factorial, la validez y la fiabilidad de la escala se realizó un análisis factorial confirmatorio (CFA) mediante structural equation modeling en una matriz de correlaciones policóricas, y usando el método de máxima verosimilitud para la estimación. Se calcularon la validez discriminante y su valor predictivo mediante curvas receiver operating characteristics. Resultados La escala en castellano mostró una consistencia interna elevada, tanto para la escala total como para sus subescalas. El coeficiente alfa de Cronbach era 0,94 para la escala total y ≥ 0,90 para las subescalas. Los valores alfa ordinales eran 0,95 para la escala total y ≥ 0,90 para las subescalas. El análisis CFA mostró un modelo de 2 factores (inatención e hiperactividad/impulsividad) intercorrelacionados. La escala ofrece buen poder discriminante (AUC = 0,97). Conclusiones La versión española del ADHD-RS-IV (ADHD-RS-IV.es) mostró una estructura bifactorial consistente con los modelos del DSM-IV-TR y DSM-5, y con el modelo propuesto por el autor de la escala original. Además, posee un alto poder discriminante, lo que lo convierte en un instrumento válido y fiable para medir la presencia y severidad de síntomas de TDAH en la población española.Objectives The purpose of this study is to validate a Spanish-language version of the 18-item ADHD Rating Scale-IV (ADHD-RS-IV.es) in a Spanish sample. Methods From a total sample of 652 children and adolescents aged 6 to 17 years (mean age was 11.14 ± 3.27), we included 518 who met the DSM-IV-TR criteria for ADHD and 134 healthy controls. To evaluate the factorial structure, validity, and reliability of the scale, we performed a confirmatory factor analysis (CFA) using structural equation modelling on a polychoric correlation matrix and maximum likelihood estimation. The scale's discriminant validity and predictive value were estimated using ROC (receiver operating characteristics) curve analysis. Results Both the full scale and the subscales of the Spanish-language version of the ADHD-RS-IV showed good internal consistency. Cronbach's alpha was 0.94 for the full scale and ≥ 0.90 for the subscales, and ordinal alpha was 0.95 and ≥ 0.90, respectively. CFA showed that a two-factor model (inattention and hyperactivity/impulsivity) provided the best fit for the data. ADHD-RS-IV.es offered good discriminant ability to distinguish between patients with ADHD and controls (AUC = 0.97). Conclusions The two-factor structure of the Spanish-language version of the ADHD-RS-IV (ADHD-RS-IV.es) is consistent with those of the DSM-IV-TR and DSM-5 as well as with the model proposed by the author of the original scale. Furthermore, it has good discriminant ability. ADHD-RS-IV.es is therefore a valid and reliable tool for determining presence and severity of ADHD symptoms in the Spanish population

    Risk of unintentional injuries in children and adolescents with ADHD and the impact of ADHD medications: A systematic review and meta-analysis

    A systematic review with meta-analyses was performed to: 1) quantify the association between ADHD and risk of unintentional physical injuries in children/adolescents (¿risk analysis¿); 2) assess the effect of ADHD medications on this risk (¿medication analysis¿). We searched 114 databases through June 2017. For the risk analysis, studies reporting sex-controlled odds ratios (ORs) or hazard ratios (HRs) estimating the association between ADHD and injuries were combined. Pooled ORs (28 studies, 4,055,620 individuals without and 350,938 with ADHD) and HRs (4 studies, 901,891 individuals without and 20,363 with ADHD) were 1.53 (95% CI = 1.40,1.67) and 1.39 (95% CI = 1.06,1.83), respectively. For the medication analysis, we meta-analysed studies that avoided the confounding-by-indication bias [four studies with a self-controlled methodology and another comparing risk over time and groups (a ¿difference in differences¿ methodology)]. The pooled effect size was 0.879 (95% CI = 0.838,0.922) (13,254 individuals with ADHD). ADHD is significantly associated with an increased risk of unintentional injuries and ADHD medications have a protective effect, at least in the short term, as indicated by self-controlled studies

    Risk of unintentional injuries in children and adolescents with ADHD and the impact of ADHD medications: protocol for a systematic review and meta-analysis

    Introduction Attention-deficit hyperactivity disorder (ADHD) has been related to increased rates of unintentional injuries. However, the magnitude of the effect and to which extent variables such as sex, age or comorbidity can influence this relationship is unknown. Additionally, and importantly, it is unclear if, and to which degree, ADHD medications can decrease the number of unintentional injuries. Due to the amount of economic and social resources invested in the treatment of injuries, filling these gaps in the literature is highly relevant from a public health standpoint. Here, we present a protocol for a systematic review and meta-analysis to estimate the relationship between ADHD and unintentional injuries and assess the impact of pharmacological treatment for ADHD Methods and analysis We will combine results from 114 bibliographic databases for studies relating ADHD and risk of injuries. Bibliographic searches and data extraction will be carried out independently by two researchers. The studies’ risk of bias will be assessed using the Newcastle-Ottawa Scale. Articles reporting ORs or HRs of suffering an injury in ADHD compared with controls (or enough data to calculate them) will be combined using Robust Variance Estimation, a method that permits to include multiple non-independent outcomes in the analysis. All analyses will be carried out in Stata. Age, sex and comorbid conduct disorders will be considered as potential causes of variance and their effect analysed through meta-regression and subgroup analysis. Sensitivity analyses will exclude articles with longer follow-ups, non-stringent definitions of ADHD or controls and statistically uncontrolled/controlled outcomes. Studies implementing a self-controlled case series methodology to investigate if ADHD drugs reduce the risk of injuries will be combined with a generalised linear mixed model using the Poisson distribution and a log link function

    Risk of poisoning in children and adolescents with ADHD: a systematic review and meta-analysis

    Poisoning, a subtype of physical injury, is an important hazard in children and youth. Individuals with ADHD may be at higher risk of poisoning. Here, we conducted a systematic review and meta-analysis to quantify this risk. Furthermore, since physical injuries, likely share causal mechanisms with those of poisoning, we compared the relative risk of poisoning and injuries pooling studies reporting both. As per our pre-registered protocol (PROSPERO ID CRD42017079911), we searched 114 databases through November 2017. From a pool of 826 potentially relevant references, screened independently by two researchers, nine studies (84,756 individuals with and 1,398,946 without the disorder) were retained. We pooled hazard and odds ratios using Robust Variance Estimation, a meta-analytic method aimed to deal with non-independence of outcomes. We found that ADHD is associated with a significantly higher risk of poisoning (Relative Risk¿=¿3.14, 95% Confidence Interval¿=¿2.23 to 4.42). Results also indicated that the relative risk of poisoning is significantly higher than that of physical injuries when comparing individuals with and without ADHD (Beta coefficient¿=¿0.686, 95% Confidence Interval¿=¿0.166 to 1.206). These findings should inform clinical guidelines and public health programs aimed to reduce physical risks in children/adolescents with ADHD

    Identity, personality and their disorders in DSM-V and ICD-10

    Get PDF
    The terms “identity” and “personality” are frequently used in medical literature in the attempt to classify certain dissociative disorders. The main diagnostic manuals used in psychiatry, the DSM-5 and the ICD-10, use the term “dissociative identity disorder” (DID) and “multiple personality disorder” (MPD) respectively, to define a disruption of identity characterized by two or more distinct personality states, or an experience of possession, as evidenced by discontinuities in sense of self, cognition, behavior, affect, perceptions, and/or memories. In scientific reports, identity and personality are apparently interchangeable terms. In our opinion, this poses an important conceptual problem that could lead to a misinterpretation of the patient condition
