PINTO, María Cristina et al. Comparing Inhibitory response in Children and Teenagers Diagnosed with Obsessive and Compulsive Disorder (OCD) and Attention Deficit Hyperactivity Disorder (ADHD). Univ.

Behavior disorders are associated with a number of factors that go beyond symptoms, including cognitive functioning and the relationship with the neurofunctional systems. In OCD and ADHD difficulties in executive functioning have been described, being the response inhibition one of the most consistent common failures in different studies despite that the two clinical pictures differ in behavioral characteristics related to this skill. The aim was to compare the inhibitory response of healthy Colombian children and adolescents and diagnosed with ADHD or OCD. A descriptive, comparative, correlational analysis of cases and controls, where the sample of 31 patients with ADHD, 31 with OCD and 66 controls were selected by intention, being of Colombian origin, between 10-19 years old to whom the Test Stroop of Colors and Words second edition was applied doing analysis of the scores T of the calculated interference. Through non-parametric Kruskal-Wallis tests, we identify general differences between the clinical groups with the controls (K-W:10.979, d/ = 2, p = 4.13x10-3). And specific differences with the Wilcoxon Test; Between Controls vs TOC (W-T p = 0.03), vs ADHD (W-T p = 2.00x10-3), but not between clinical groups TOC vs ADHD (p = 0.27). When comparing through U-Mann- Whitney test by age range differences are found between the same groups for participants between 13-16 years in ADHD vs controls (p = 5.00x10-3), identifying correlation between age and interference only for the TOC group (R2 = 0.98). As described in the scientific literature, it is not possible to identify differences in case-control performance in inhibitory control of interference between people with OCD and ADHD, but between these and controls, confirming the common aspect of inhibitory failures, even when differ in behavioral manifestations. Age represents an important element indicating that there is a change component related to maturation of the nervous system, leading to better inhibition performance as the age for the OCD group increases.
