EEG lazy wave refers to a kind of EEG activity with low frequency and slow waveform, which often appears in the prefrontal area of people in awake state. The appearance of lazy waves is related to emotional states such as difficulty in concentration, fatigue, lack of motivation and anxiety. Their appearance can be used as indicators to diagnose diseases such as attention deficit hyperactivity disorder and chronic pain syndrome, and also related to some mental diseases such as depression and anxiety.

EEG lazy wave is one of the important indexes in EEG examination, which can be detected by professional EEG instruments. In practical application, the recording and analysis of patients' brain waves can provide valuable reference information for clinicians.
