Characterization Of Neuropsychological Functioning In Children With Clinical Features Of ADHD

Attention deficit with/without hyperactivity is one of the most controversial and currently studied disorders. From a neuropsychological point of view, its characterization is gaining ground with a view to obtaining a more effective diagnosis and treatment. However, there are not many studies that have compared the different profiles of ADHD from this approach. Thus, the aim of the present study was to compare groups of school-aged children with characteristics of attention deficit, hyperactivity-impulsivity and controls, with respect to the neuropsychological variables: saccadic movements, auditory discrimination, executive functions and working memory. A sample of 36 students aged 8-10 years was evaluated, distributed equally among the 3 groups. After analyzing the results obtained from the application of different tests: King-Devick,(KD), Phoneme Articulation Test (PAF), Stroop Color and Word Test and the index of working memory of the Weschler Intelligence Scale for children; it was confirmed that subjects with behavioral characteristics of attention deficit and hyperactivity showed a worse performance than the control group in all variables, and no statistically significant differences were found between inattentive and hyperactive ADHD profiles. Results were discussed and it is concluded that based on the present comparative study, a differential neuropsychological profile cannot be established between children with a characteristic pattern of inattention versus one of hyperactivity-impulsivity, and generally the children with clinical features of ADHD presented a decrease in the neuropsychological variables evaluated.
