Abstract: This study was performed to assess whether the theta/beta ratio can be regarded as an indicator of pediatric patients’ evolution while receiving treatment for ADHD. This required a spectral analysis of the electrophysiological power output from several channels with reference at the vertex (Cz). The files and EEG signals of sixteen clinical cases, which included children and adolescents from 4 to 16 years of age, were analyzed. The analysis of the EEG signals was performed using the Fast Fourier Transform (FFT) to obtain the frequency bands. Patients were under pharmacological treatment for at least one year and had at least 2 EEG studies. The results indicate that a good correlation exists between the theta/beta ratio and the patient’s clinical evolution. 42% of the patients who had 3 or more EEG’s, showed good correlation (r > 0.9), which was coherent with their good clinical evolution. 33% showed linear tendency (0.63 < r < 0.73), with variable response and recovery tendency. 25% had bad correlation (r < 0.3), also with variable treatment response. These results relate to poor adherence to the pharmacological treatment. (More)
