Gamma Power and Its Association With Lipid Profile and Cognitive Impairment in Schizophrenia: A Resting-State EEG Study

Lipid profile abnormalities in SCZ are associated with exacerbated cognitive impairment and attenuated gamma-band power. Gamma activity may reflect underlying synaptic and network dysfunction related to lipid dysregulation and serve as a promising noninvasive EEG biomarker for cognitive risk stratification in metabolically vulnerable SCZ subgroups.
