Implication

Observational study reveals localized hypometabolism unrelated to spike frequency in partial epilepsy, indicating metabolic and electrical tests capture distinct aspects of brain dysfunction.

Key Points

To evaluate interictal cerebral glucose metabolism using positron computed tomography and assess its relationship to electroencephalographic abnormalities in partial epilepsy.
Assessed 50 patients with partial seizure disorders using interictal 18F-fluorodeoxyglucose positron computed tomography.
Conducted simultaneous electroencephalographic monitoring using scalp and sphenoidal electrodes in 33 patients and stereotaxic depth electrodes in 17 patients.
Identified discrete zones of hypometabolism in 35 of 50 patients, while only 1 patient displayed focal interictal hypermetabolism.
Observed focal structural abnormalities on CT scans in only 4 patients, which matched the presumed epileptogenic site in 2 patients.
Found no quantitative correlation between the degree of focal hypometabolism and the frequency of interictal spikes or nonepileptiform EEG abnormalities.
