Brain structural change associated with Cognitive Behavioral Therapy in maltreated children.

BACKGROUND: Severely maltreatment child is a harmful social factor that can disrupt normal neurodevelopment. Two commonly reported effects of maltreatment are post-traumatic stress disorder (PTSD) symptoms and brain structural and functional alteration. While Trauma-Focused Cognitive-Behavioral Therapy (TF-CBT) is effectively used to reduce PTSD symptoms in maltreated children, yet, its impact on brain structural alterations has not been fully explored. This study investigated whether TF-CBT can attenuate alterations in brain structures associated with PTSD in middle childhood. METHODS: The study evaluated the longitudinal effects of Trauma-Focused Cognitive-Behavioral Therapy (TF-CBT) on post-traumatic stress disorder (PTSD) symptoms and gray matter volume (GMV) in two groups of children under 12 years old: maltreated children (MC) and healthy non- maltreatmentd children (HC). Structural magnetic resonance images T1 were obtained before and after TF-CBT in the MC group, while the HC group was scanned twice within the same time interval. Voxel-based morphometry (VBM) was used to analyze GMV changes over time. RESULTS: After TF-CBT, maltreated children showed significantly reduced PTSD symptoms. Furthermore, a significant group-by-time interaction effect was observed in certain areas of the Left Temporal, Left Occipital, and bilateral Frontal Cortex, the Basal Ganglia and Cerebellum. These interaction effects were driven by a GMV decrease in the MC group compared to the HC group. GMV changes can be predicted with clinical improvement in the left Middle Temporal gyrus, left Precuneus, and Cerebellum. CONCLUSIONS: Our results suggest that TF-CBT intervention in very young maltreated children may have an effect on gray matter. This evidence demonstrates the importance of timely intervention when neuroplasticity mechanisms may be activated.

Can psychopathy be prevented? Clinical, neuroimaging, and genetic data: an exploratory study.

The aim of the study was to explore the relationship among brain functional activations elicited by an emotional paradigm, clinical scores (PTSD, anxiety, and depression), psychopathic traits, and genetic characteristics (5-HTTLPR) in a group of severely maltreated children compared to a healthy control group before and after the implementation of a Trauma Focused-Cognitive Behavioral Therapy. The final sample consisted of an experimental group of 14 maltreated children (mean age = 8.77 years old, S.D. = 1.83) recruited from a non-governmental shelter in Mexico City for children who had experienced child abuse and a control group of 10 children from the general population (mean age = 9.57 years old, S.D. = 1.91). Both groups were matched according to age and gender and were assessed before and after the implementation of the aforementioned therapy by means of clinical scales and an emotional paradigm that elicited brain activations which were recorded through functional magnetic resonance imaging. Genotyping of the 5-HTTLPR polymorphism was made at first assessment. A region of interest analysis showed amygdala hyperactivation during exposure to fear and anger stimuli in the maltreated children before treatment. Following therapy, a decrease in brain activity as well as a decrease in clinical symptoms were also observed. 5-HTTLPR polymorphism did not show any effect on the severity of clinical symptoms in maltreated children. Trauma-Focused Behavioral Therapy may help reorganize the brain's processing of emotional stimuli. These observations reveal the importance of an early intervention when the mechanisms of neuroplasticity may be still recruited.

La Ciudad de las Niñas y los Niños de Huesca, una oportunidad en el diseño de entornos y políticas públicas saludables / The City of Girls and Boys of Huesca (Spain), an opportunity for designing healthy environment and public policies

La Ciudad de las Niñas y los Niños es un proyecto internacional que pretende fomentar la autonomía y la participación infantil plena en la construcción de la ciudad. Tras aprobarse en 2011 en el pleno del Ayuntamiento de Huesca, se crearon el Consejo de las Niñas y los Niños y el Laboratorio de la Ciudad, órganos en los que hay representación de todos los colegios de Huesca. Para hacer explícito el trabajo sobre la salud se han incorporado actividades como «Caminos saludables», en la que se utiliza la técnica del mapeo de activos. Además del trabajo interdisciplinario entre distintas áreas del ayuntamiento, profesionales de los sectores educativo (colegios y universidad), sanitario y social, se observan impactos en el entorno físico urbano, con la remodelación de un parque, una calle y una plaza; y en los estilos de vida de los escolares, al aumentar el número de aquellos que van andando solos al colegio

The City of Girls and Boys of Huesca (Spain) is an international project that seeks to foster children's autonomy and full participation in the construction of the city. Following its formal approval at the City Council of Huesca, the Girls and Boys Board and the City Laboratory were created, both of which include children from all the schools of Huesca. To highlightthe work on health, activities such as "Healthy School Paths", in which the asset mapping technique is used, were incorporated. Besides the interdisciplinary work among different areas of the city council, professionals from education (schools and university), health and social services, effects on the urban physical environment, with one street, park and square remodelled; and on the children's lifestyles, with more children walking to school alone, have been observed

Parents' Willingness and Perception of Children's Autonomy as Predictors of Greater Independent Mobility to School.

The present study aimed to examine the factors associated with different forms of independent mobility (IM) to school (IM one way and IM both ways) according to their parents' opinions. To do so, several variables were evaluated: how parents assess their children's autonomy, the difficulty they perceive for IM to school, reasons for IM/no IM to school, parents' willingness for IM to school, frequency of children's IM for leisure activities, children having house keys and dangers perceived in the neighborhood. Family-related socio-demographic variables were also assessed: number of children, position occupied by them in the family, family composition, living with both parents or just one, and each parent's nationality, level of education and job status. This study examined the data collected from 1450 parents (mothers and fathers) with children studying Primary Education years 4, 5 and 6 (M age = 10.53, SD = 0.90). The results showed that 42.3% of the schoolchildren did not practice IM to school, 18.1% practiced IM one way (they went to or from school alone), and 39.5% practiced IM both way (they went to/from school alone). These findings underline the importance of parents' willingness for IM to school, and how the balance between how they perceive their children's autonomy and difficulty for IM is relevant for greater IM to school.
