Serum 5-HT levels were measured in postictal and interictal
venous blood samples.
While a variety of EEG abnormalities such as deterioration on the ground rhythm, various paroxysmal activities and normal interictal
EEG, have been described in individuals with PDE, none is pathognomonic for this disorder.
No seizure or interictal
epileptiform activity appeared during those episodes.
Two of the authors (JH Chen and XQ Zhou) independently reviewed ictal and interictal
Five hundred thirty-nine patients underwent neuroimaging (CCT or MRI), and 535 patients underwent interictal
EEG examination during the last admission.
EEG baseline activity was 6-8 Hz, and very frequent paroxysmal bilateral temporal slow and sharp-slow waves were revealed.
EEG was done routinely for all patients in the interictal
burden attributable to episodic headache: findings from the Eurolight project J Headache Pain.
In one study, LEV was given to children with RLS, who also had interictal
EEG can be helpful, but "there's no reliable test to differentiate the two."
For participants with epilepsy, additional inclusion criteria included the following: clinical manifestations compatible with epileptic seizures; at least one interictal
electroencephalogram examination with epileptiform discharges; more than one seizure per month (either focal with or without generalization or generalized seizure) in the last 12 months; use of one or two antiepileptic medications.
The paper presented a comparison of various entropy methods used for the classification of normal, interictal
, and ictal EEG signals.
