The clinical evaluation was designed to investigate the appearance of seizures during diurnal and nocturnal sleep. The pharmacological response to coffee or amphetamine was investigated after normalization of previous anticonvulsant treatment. Seven of 10 patients (70%) presented with seizures during the siesta, and in 3 of 10, seizures occurred if they fell asleep at any time of the day. Seizures were detected in later hours of the night in five patients as sleep reinitiation seizures or seizures without previous awakening. The response to anticonvulsants alone was disappointing. The addition of coffee or amphetamine suppressed seizures of sleep beginning at night or during the siesta. Neither of them had an influence on sleep diurnal seizures outside of the siesta or on seizures of nocturnal sleep reinitiation. Suppression of coffee or amphetamine was followed by reappearance of the seizures. © Williams & Wilkins 1992. All Rights Reserved.
