Transient hypothyroidism during lactation alters the development of the corpus callosum in rats. An in vivo magnetic resonance image and electron mic…
2020
Magnetic resonance imaging (MRI) data of children with late diagnosed congenital hypothyroidism and cognitive alterations such as abnormal verbal memory processing suggest altered telencephalic commissural connections. The corpus callosum (CC) is the major inter-hemispheric commissure that contra-laterally connects neocortical areas. However, in late diagnosed neonates with congenital hypothyroidism, the possible effect of early transient and chronic postnatal hypothyroidism still remains unknown. We have studied the development of the anterior, middle and posterior CC, using in vivo MRI and electron microscopy in hypothyroid and control male rats. Four groups of methimazole (MMI) treated r…
Enhancement of Anticipatory Postural Adjustments by Virtual Reality in Older Adults with Cognitive and Motor Deficits: A Randomised Trial.
2021
Background: Postural activities involved in balance control integrate the anticipatory postural adjustments (APA) that stabilize balance and posture, facilitating arm movements and walking initiation and allowing an optimal coordination between posture and movement. Several studies reported the significant benefits of virtual reality (VR) exercises in frail older adults to decrease the anxiety of falling and to induce improvements in behavioural and cognitive abilities in rehabilitation processes. The aim of this study was thus to test the efficiency of a VR system on the enhancement of the APA period, compared to the use of a Nintendo Wii system. Methods: Frail older adults (n = 37) were i…
Conductas de aprendizaje en niños con trastorno del espectro autista con y sin comorbilidad con déficit de atención e hiperactividad
2018
La literatura ha explorado los problemas en el aprendizaje que presentan los niños con trastorno del espectro autista (TEA), pero apenas se ha analizado el impacto de la comorbilidad con déficit de atención e hiperactividad (TDAH) sobre el aprendizaje en niños con TEA. Objetivos. 1) Analizar las diferencias en la conducta de aprendizaje de niños con TEA con y sin comorbilidad con TDAH y niños con desarrollo típico (TD); 2) Investigar la asociación entre diferentes dominios de conductas de aprendizaje y problemas conductuales y emocionales, en niños con TEA y niños con TEA+TDAH. Método. Participaron 87 niños (30 con diagnóstico de TEA de alto funcionamiento, 22 con TEA+TDAH y 36 con TD entre…
The hierarchical factor model of ADHD: invariant across age and national groupings?
2011
Attention-Deficit/Hyperactivity Disorder (ADHD) is characterized by problems with attention, impulsivity, and hyperactivity. The diagnosis derives from 18 symptoms indexing these behavioural domains [American Psychiatric Association (APA), DSM-IV-TR, 2000]. There is substantial continuity in maintaining a diagnosis of ADHD from childhood to adolescence (Faraone, Biederman, & Mick, 2006); however the phenotypic expression is highly variable within the diagnosed group and across time (Barkley, 2006; Nigg, 2006). Current diagnostic formulations distinguish between symptoms of inattention and those of hyperactivity-impulsivity. Three ADHD subtypes are recognized in the DSM-IV: the predominantly…
Inclusion of pupils with ADHD symptoms in mainstream classes with PBS
2017
Inclusion is never only a practical issue of placement. School-wide systemic change, together with well-functioning, multi-tiered support, can promote the inclusion of all pupils. This paper draws on research conducted in two mainstream primary schools in Finland. The primary focus was to gain insight into practical solutions to facilitate the inclusion of pupils with attention-deficit hyperactivity disorder (ADHD) in mainstream teaching. Using an experimental, multiple-baseline, single-case design, we examined the effects of Check-in Check-out (CICO) support on changes in the behaviour of two pupils who displayed ADHD-type behaviours. The key features of CICO are brief morning and afternoo…
Structural validity of the Spanish Wechsler Intelligence Scale for Children–Fourth Edition in a large sample of Spanish children with attention-defic…
2018
The factorial structure of the WISC-IV for 859 Spanish children diagnosed with ADHD was examined. A bifactor model with the four factors first identified by Wechsler (2003a) was the best fit to the...
Testosterone and attention deficits as possible mechanisms underlying impaired emotion recognition in intimate partner violence perpetrators
2016
Several studies have reported impairments in decoding emotional facial expressions in intimate partner violence (IPV) perpetrators. However, the mechanisms that underlie these impaired skills are not well known. Given this gap in the literature, we aimed to establish whether IPV perpetrators (n = 18) differ in their emotion decoding process, attentional skills, and testosterone (T), cortisol (C) levels and T/C ratio in comparison with controls (n = 20), and also to examine the moderating role of the group and hormonal parameters in the relationship between attention skills and the emotion decoding process. Our results demonstrated that IPV perpetrators showed poorer emotion recognition and …
Seasonal evolution of the quality of fresh glasshouse tomatoes under Mediterranean conditions, as affected by air vapour pressure deficit and plant f…
2000
Abstract Changes in yield and quality of fresh tomatoes in response to air vapour pressure deficit (VPD) and plant fruit load were studied under Mediterranean summer conditions. Plants thinned to three or six fruits per truss were grown in two compartments, one at a VPD below 1.5 kPa, the other without VPD control. The seasonal trend in fruit yield and quality was assessed from April to September by weekly measurement of number, fresh weight and dry matter content of harvested fruits, together with the occurrence of blossom-end-rot (BER) and cracking. On two occasions, in July and September, sugar and acid content was measured at three ripening stages. The seasonal decrease in fresh yield w…
The influence of serotonin- and other genes on impulsive behavioral aggression and cognitive impulsivity in children with attention-deficit/hyperacti…
2008
Contains fulltext : 70708.pdf (Publisher’s version ) (Open Access) ABSTRACT: BACKGROUND: Low serotonergic (5-HT) activity correlates with increased impulsive-aggressive behavior, while the opposite association may apply to cognitive impulsiveness. Both types of impulsivity are associated with attention-deficit/hyperactivity disorder (ADHD), and genes of functional significance for the 5-HT system are implicated in this disorder. Here we demonstrate the separation of aggressive and cognitive components of impulsivity from symptom ratings and test their association with 5-HT and functionally related genes using a family-based association test (FBAT-PC). METHODS: Our sample consisted of 1180 o…
Optimization of care through film music: practices in Secondary Education
2015
La estimulación del alumnado con Trastorno por Déficit de Atención debe implicar una activación del proceso cognitivo, físico y motor. El proceso metodológico que se propone para garantizar dicha estimulación atencional en el aula de Secundaria se centra en la audición, el movimiento, la composición y la improvisación a partir de música cinematográfica. La utilización de este tipo de música más próxima al alumnado supone un aumento de las posibilidades de cambio y la mejora de las respuestas de aprendizaje significativo, debido a la optimización de la atención a través de actividades musicales, más atractivas para el alumnado. Abstract: Stimulation of students with Attention Deficit Disorde…
