Rhythmic temporal theta bursts of drowsiness (RTTD), also known as "psychomotor variant", and subclinical rhythmic EEG discharge of adults (SREDA) are two EEG patterns of uncertain significance that occur without any correlation with epilepsy. Each of these patterns has been described to occur alone and in the literature there are no previous reports of co-occurrence of the two distinct benign EEG variants in the same patient. We describe the coexistence of RTTD and SREDA in EEG recordings from the same subject. Although the coexistence of two distinct EEG variants in the same patient is a rarity, these patterns are not so infrequently encountered when present alone and should thus be promptly recognised in order to avoid misdiagnosis of epilepsy due to an over-interpretation of normal sharp patterns.

Abstract
Rhythmic temporal theta bursts of drowsiness (RTTD), also known as "psychomotor variant", and subclinical rhythmic EEG discharge of adults (SREDA) are two EEG patterns of uncertain significance that occur without any correlation with epilepsy. Each of these patterns has been described to occur alone and in the literature there are no previous reports of co-occurrence of the two distinct benign EEG variants in the same patient. We describe the coexistence of RTTD and SREDA in EEG recordings from the same subject. Although the coexistence of two distinct EEG variants in the same patient is a rarity, these patterns are not so infrequently encountered when present alone and should thus be promptly recognised in order to avoid misdiagnosis of epilepsy due to an over-interpretation of normal sharp patterns.Pubblicazioni consigliate
