INFLUENCIA DE FACTORES FAMILIARES Y PERSONALES EN LA EVOLUCIÓN NEGATIVA DEL TDAH

2016

Abstract.INFLUENCE OF PERSONAL AND FAMILY FACTORS ON THE NEGATIVE COURSE OF ADHDObjective. To study the effect of the cumulative adversity on the course of ADHD symptoms, associated problems and dysfunctionality of ADHD children. Method. 61 families of children with a clinical diagnosis of ADHD combined subtype were evaluated on two different times (Time I: mean age = 8.7; Time II: mean age = 11). We developed a personal risk index (high levels of ADHD symptoms, high number of associated problems, presence of oppositionism, stressful child characteristics and family history of ADHD), a family risk index (presence of mothers’ psychopathology, high parental stress and dysfunctional discipline…

Conformational investigation of alpha,beta-dehydropeptides. IX. N-Acetyl-(E)-alpha,beta-methylamide: stereoelectronic properties from infrared and th…

1998

The Fourier transform infrared spectra of Ac-(E)-deltaAbu-NHMe were analyzed to determine the predominant solution conformation(s) of this (E)-alpha,beta-dehydropeptide-related compound and the electron density perturbation in its amide groups. The measurements were performed in dichloromethane and acetonitrile in the region of mode vs (N-H), amide I, amide II and vs (C(alpha)=Cbeta). The equilibrium geometrical parameters, calculated by a method based on the density functional theory with the B3LYP functional and the 6-31G* basis set, were used to support spectroscopic interpretation and gain some deeper insight into the molecule. The experimental and theoretical data were compared with th…
