Fifty ADHD patients and 50 normal children were selected as experimental subjects. EEG signals were recorded in a quiet state, attention state and task execution state. The results showed that the EEG power density values at most electrode positions in ADHD patients were higher than those in normal children, especially in the θ and α frequency ranges. Therefore, we believe that frequency domain analysis is an effective method for identifying and studying ADHD, and provides a theoretical basis for establishing a reference model.【Keywords】ADHD; frequency domain analysis; EEG power characteristics; reference model.
