Value of scalp delayed rhythmic ictal transformation (DRIT) in presurgical assessment of temporal lobe epilepsy.

Objectives: To estimate the localising and lateralising value of delayed rhythmic ictal transformation (DRIT) on the scalp EEG during presurgical assessment for temporal lobe epilepsy.

Methods: Two hundred and eighty eight seizures recorded simultaneously with scalp and foramen ovale (FO) electrodes were studied retrospectively in 110 patients. DRIT was defined as sustained regular rhythmic waveforms seen on scalp recordings after scalp seizure onset.

Electroencephalographic and clinical features of cerebral malaria.

Background: Seizures are a prominent feature of childhood cerebral malaria, and are associated with an increased risk of death and neurological sequelae. We present the electroencephalographic (EEG) findings from a detailed clinical and electrophysiological study.

Methods: Children with cerebral malaria had EEGs recorded within six hours of admission, and at 12 hourly intervals until recovery of consciousness.

Seizures and status epilepticus in childhood cerebral malaria.

Prolonged, multiple seizures complicate a high proportion of cases of childhood cerebral malaria, and several studies have shown an association between these and neurological sequelae. We prospectively studied 65 patients (38 female) admitted to Kilifi Hospital in 1994. Electroencephalographic recordings (EEGs) were made at 12-hourly intervals, with continuous recordings made on a cerebral function analysing monitor (CFAM).
