Methods: Children with untreated absence seizures were studied using video-EEG recording. The influence of state of arousal, provocation (hyperventilation, photic stimulation), age, and epilepsy syndrome on specific EEG features was analyzed. Results: Five hundred nine seizures were evaluated in 70 ...
Absence seizures are usually considered to present a short suspension of consciousness, concomitant with the 3-Hz spike and wave seen in the EEG. For this reason, mechanisms of generation of spike-and-wave discharges have long been negatively associated with mechanisms of consciousness. We present ...
[5] The seizures in these conditions are called typical absence seizures and are usually associated with generalized 3-4 Hz spike-and-slow-wave complexes on EEG. [6] In childhood absence epilepsy, seizures are frequent and brief, lasting just a few seconds (pyknoleptic). Some children can...

(1) Typical absence seizures consist of behavioral arrest with or without automatisms, usually last 30-60 seconds, and demonstrate a characteristic 3-Hz generalized spike-wave (GSW) pattern on EEG, often in response to hyperventilation.(2) Children may have hundreds of episodes daily, many of ...
Learning-impaired children can present with a clinical history suggesting additional problems, including attention deficit disorder and absence seizures. Physicians use clinical judgment in diagnosing the former, but rely heavily on the electroencephalogram (EEG) to diagnose the latter. Most clinicians are...
Such algorithms currently reach high sensitivity and specificity of detection, despite high interindividual differences in seizure EEG parameters or interictal spiking17, 18. Different seizure prediction algorithms have been designed for seizures accompanying temporal lobe epilepsy, with different succes rates...
However, there is no direct evidence to support the specific involvement of NLG2 in epileptic seizures. In addition, the underlying mechanisms and circuits involved are unknown. In this study, we find that NLG2 knockout (KO) mice exhibit abnormal EEG activity and behavioral arrests reminiscent ...
