Electrodecremental status epilepticus is classically described in infants and children with severe refractory epilepsy, mental retardation, and structural brain abnormalities. We describe a 24-year-old woman who presented to the emergency department with prolonged tonic status epilepticus which evolved into stimulus-induced diffuse voltage attenuation (SIDVA) pattern in the setting of aseptic meningoencephalitis. There was no history of seizures or further events after recovery. This is the first report of a SIDVA pattern in an adult without a history of epilepsy.

    ABSTRACT: A 10-year-old girl with Lennox-Gastaut syndrome who received intravenous lorazepam for atypical absence status seizures is reported. Tonic seizures occurred immediately and appeared to represent a paradoxical seizure exacerbation. We also review other patients with paradoxical seizure exacerbation by benzodiazepines.

    ABSTRACT: A diffuse electrodecremental ictal pattern with other forms of epilepsy and has been considered to reflect a generalized seizure disorder of diffuse cortical or subcortical (brainstem) origin. In some seizures associated with DEP, however, focal ictal manifestations have been observed. We reviewed the records of all patients admitted to our seizure monitoring unit for 3 years and detected 39 patients with seizures associated with DEP. In 23 of 39 patients, clinical ictal behaviors resembled seizures of unilateral supero/mesiofrontal lobe origin and interictal EEG showed a prominent unilateral frontal component. Nine of 39 had complex absences (CA)/complex partial seizures (CPS); 4 of them were of unilateral frontal lobe origin. Seven of 39 patients had tonic or atonic seizures. Seven patients were studied further with subdural electrodes. Ictal onsets showed a highfrequency frontal lobe discharge. We conclude that in a subgroup of patients a generalized electrodecremental pattern on scalp EEG results from a regional cortical high-frequency ictal discharge originating in a single frontal lobe.

    ABSTRACT: Patients with seizures accompanied by generalized cortical electrodecremental event (CEE) have clusters of clinical spells with tonic, dystonic, or atonic components and involvement of autonomic functions. When electroencephalographically detectable foci are present, they behave in a peculiar way; throughout the entire cluster of seizures focal spiking is reduced in the short interictal periods as well as during each individual seizure with CEE, at which time it is suppressed. Focal firing reappears reinforced at the end of each spell and also at the end of the cluster. These facts suggest that the foci responsible for CEE are deeply located. A complex excitatory-inhibitory feedback probably exists between cortical and subcortical foci. These seizures should be differentiated from similar attacks of nonepileptic or epileptic nature. A correct diagnosis is essential given the different therapeutic implications.
