Why the study?
Early identification of abnormal brain activity in neurological disorders is crucial for devising suitable treatments and interventions, but clear demarcation between normal and abnormal EEG metrics remains challenging.
Population
Individuals with neurological and mental disorders and healthy controls
Comparison
Four feature extraction approaches: EEG frequency band vs raw data vs power spectral density vs wavelet transform
Design
Classification and visualization study
Key result
The integration of wavelet features and visual analysis of EEG signals proved effective in identifying neurological disabilities, with the frontal lobe emerging as a crucial area for differentiation.

May aid early pattern detection in neurological disabilities via DWT-visualization; leaves open need for clinical validation before practice change.
Integrating wavelet features and visual analysis of EEG signals is effective for identifying neurological disabilities, particularly using data from the frontal lobe.
Ji et al. (2023) studied Neurological and mental disorders. Integration of discrete wavelet transform, machine learning, and visual analysis of EEG signals vs. Other feature approaches (EEG frequency band, raw data, power spectral density) was evaluated on Classification performance to differentiate neurological disabilities in short EEG segmentations. The integration of wavelet features and visual analysis of EEG signals proved effective in identifying neurological disabilities, with the frontal lobe emerging as a crucial area for differentiation.
