ABSTRACT

<p><b>OBJECTIVE</b>Measuring the serum concentrations of adrenocorticotropic hormone (ACTH) and cortisol in epileptic seizures during sleep to investigate their link to the EEG changes.</p><p><b>METHODS</b>Pre-surgical evaluation was performed by video-EEG monitoring using 24 channel recording. Thirty six epilepsy patients could be attributed to two groups: 28 patients had spontaneous seizures, and the other 8 patients whose seizures were induced by bemegride. Another 11 persons with confirmed psychogenic non-epileptic seizures (PNES) served as control group. Blood samples were obtained at five points: wake (08:00 a.m.), sleep (00:00 a.m.), and shortly before, during and after an epileptic seizure. The serum ACTH and cortisol were measured and analyzed by chemiluminescent immunoassay.</p><p><b>RESULTS</b>The levels of ACTH and cortisol in serum underwent significant changes: declining below the average sleep-level shortly before seizures, increasing during seizures, and far above the average wake-level after seizures (P < 0.001). Such changes did not occur in the control group (P > 0.05). The ACTH and cortisol levels had no significant difference between spontaneous group and bemegride-induced group (P > 0.05).</p><p><b>CONCLUSION</b>The serum concentrations of ACTH and cortisol during sleep seizures are linked with pre-ictal and ictal EEG changes in epilepsy patients.</p>
