    The study assessed metabolic connectivity variations in focal epilepsy subtypes: RTLE, LTLE, and ETLE, using 18F-FDG PET imaging.

  • 2

    Significant alterations in metabolic network connectivity were observed in RTLE, LTLE, and ETLE patients compared to healthy controls.

  • 3

    Key disparity nodes in RTLE included the right Rolandic area and bilateral cerebellum, while LTLE showed variations in the left middle temporal gyrus.

  • 4

    ETLE patients exhibited network abnormalities related to the unilateral postcentral gyrus and bilateral supramarginal gyrus.

  • 5

    In the ETLE group, edge connectivity of certain cerebral regions positively correlated with prognosis classifications.
