OBJECTIVE: Attention deficit hyperactivity disorder (ADHD) is an alteration that begins early in infancy and whose cardinal symptoms are inattention, hyperactivity and impulsivity. There are few studies for specific tests to measure Quality of Life (QoL) in children with ADHD. METHODS: We evaluated QoL of 120 children from 7-12 years of age with ADHD and of a group of 98 healthy control children. To measure QoL, we utilized the Questionnaire of Quality of Life for Children in Pictures (AutoQuestionnaire Qualité de Vie Enfant Imagé, AUQUEI). We evaluated anxiety in children by the Children´s Manifest Anxiety Scale-Revisited (CMAS-R). We compared results among groups and employed the calculation of correlation between the AUQUEI questionnaire and the CMAS-R scale. RESULTS: The total average of the AUQUEI questionnaire in children with ADHD was 45.2, while in the control group it was 54.3 (p<0.05). We also observed significant differences between the control group and groups of children with ADHD in the CMAS-R scale. We found significant correlations between AUQUEI questionnaire and CMAS-R scale. CONCLUSION: The main result was to the disclosure that low QoL scores in ADHD children was anxiety-related.

Objective: To perform a complete Intelligence quotient (IQ) measurement (verbal, performance, and total) and subsequently, to compare executive function (EF) measurements in subgroups of children with attention deficit-hyperactivity disorder (ADHD) with a control group. Method: We studied a group of children from 7-12 years of age from public elementary schools. Children were selected by means of Diagnostic and Statistical Manual of Mental Disorders-IV-Revised (DSM-IV-R) parent and teacher questionnaires for ADHD. EFs were screened by Weschler Intelligence Scale for Children (WISC-R) performance intelligence quotient (IQ) determination of the following sub-tests: picture completion; block designs, and object assembly tests. Simultaneously, total (T-), performance (P-), and verbal (V-) IQs were measured for each patient. Results: We studied 26 control subjects, and 35 children with ADHD. Numbers of children in each ADHD subtype group were as follows: 15 in the combined group (-C), 13 in the inattentive group (-I), and 7 in hyperactivity group (-H). We found significant lower EF scores in picture arrangement (F=3.76, df 3,57, p=0.01), block design (F=4.55, df 3,57, p<0.01), and object assembly (F=4.52, df 3,57, p<0.01). Post-hoc analysis showed that differences were located among ADHD-C, ADHD-I, and ADHD-H groups when compared with controls. We found significantly lower cognitive scores in the ADHD-I group as follows: P-IQ (F=3.57, df 3,57, p=0.02), and T-IQ (F=2.90, df 3,57, p=0.04). Conclusion: Our results showed that screening of EF alteration in children with ADHD is easy and rapid by means of certain P-IQ determination sub-scales of the WISC test; moreover, complementary IQ determination can be measured simultaneously. Overall, children with ADHD exhibited an EF alteration. ADHD-I children demonstrated lower P-IQ, and T-IQ scores than control children.

Método: Se estudiaron niños de 7-12 años, provenientes de escuelas oficiales primarias. Se les aplicó el cuestionario de criterios diagnósticos de TDAH del DSM-IV-R para padres y maestros.

Objective: To compare frequency of sleep disorders (SD) and executive dysfunction (ED) in children with attention deficit-hyperactivity disorder (ADHD) and a control group. Method: We studied 156 children with ADHD with a mean age of 8.5 years, and a control group with 111 children with a mean age of 8.3 years. We utilized the Pediatric Sleep Questionnaire (PSQ) to screen SD and the working memory measurement from the Wechsler intelligence scale for children (WISC-IV) to screen ED. Results: We did not observe an increased frequency of SD in children with ADHD compared with the controls. However, we did identify ED in children with ADHD; additionally a significant correlation was observed between the type of ADHD and SD and among ED, WISC-IV measurements, and type of SD in children with ADHD. Conclusion: An increase of SD frequency in children with ADHD was not observed, but we did identify ED in children with ADHD. Additionally, a correlation among ADHD types, SD, ED, and WISC-IV measurements was observed in children with ADHD.Keywords: attention deficit-hyperactivity disorder, sleep disorders, executive dysfunction, pediatric sleep questionnaire, Wechsler intelligence scale for children. REsumEnObjetivo: Comparar la frecuencia de trastornos del sueño (TS) y disfunción ejecutiva (DE) en niños con trastorno por déficit de atención-hiperactividad (TDA-H) y un grupo control. Método: Estudiamos 156 niños con TDA-H con una media de 8,5 años. El grupo control incluyó 111 niños con una media de 8,3 años. Utilizamos la versión traducida del Cuestionario pediátrico del sueño (CPS) para tamizar TS. Para estudiar la DE, usamos la medición de la memoria de trabajo de la escala de inteligencia de Wechsler para niños-IV (WISC-IV). Resultados: No encontramos una mayor frecuencia de TS en niños con TDA-H. Sin embargo, encontramos DE y correlaciones entre los diferentes tipos de TDA-H, y entre los TS, DE y de mediciones del WISC-IV. Conclusión: No hallamos un incremento en la frecuencia de TS en niños con TDA-H. Encontramos evidencia de DE y correlaciones entre el tipo de TDA-H, TS, DE y medidas del WISC-IV.Palabras clave: trastorno por déficit de atención-hiperactividad, trastornos del sueño, disfunción ejecutiva, cuestionario pediátrico del sueño, escala de inteligencia infantil de Wechsler.Attention deficit-hyperactivity disorder (ADHD) is an alteration that begins early in infancy and whose main symptoms include inattention, hyperactivity, and impulsivity 1,2 . Children with ADHD present adaptation difficulties in several areas of their life, such as at school, at home, or in different social environments, due mainly to impulsivity, hyperactivity, and inattention that may affect their quality of life (QoL) 3 . Moreover, children with ADHD frequently present different co-morbidities such as oppositional defiant disorder (ODD), learning disabilities (LD), conduct disorder (CD), or others.
