A paper published in 2023 showed that burst suppression and epilepsy may share the same ephaptic coupling mechanism. [6] When inhibitory control is sufficiently low, as in the case of certain general anesthetics such as sevoflurane (due to a decrease in the firing of interneurons [7]), electric fields are able to recruit neighboring cells to fire synchronously, in a burst suppression pattern.
Syndromes are characterized into 4 groups based on epilepsy type: [1] a. Generalized onset epilepsy syndromes. These epilepsy syndromes have only generalized-onset seizures and include both the idiopathic generalized epilepsies (specifically childhood absence epilepsy, juvenile absence epilepsy, juvenile myoclonic epilepsy and epilepsy with generalized tonic- clonic seizures alone), as well as ...
Electroencephalography is the measurement of brain activity through the surface of the scalp. [1] Electroencephalography data can be viewed as a qualitative wave form, or it can be further processed through analytical procedures to produce quantitative electroencephalography (qEEG). [2]
EEG can detect abnormal electrical discharges such as sharp waves, spikes, or spike-and-wave complexes, as observable in people with epilepsy; thus, it is often used to inform medical diagnosis. EEG can detect the onset and spatio-temporal (location and time) evolution of seizures and the presence of status epilepticus.
The temporal lobe epileptiform discharge is a pattern seen on the electroencephalgram (EEG) test; temporal lobe epileptiform discharges occur between seizures and confirm the diagnosis of temporal lobe epilepsy. [3] Long-term video-EEG monitoring may record the behavior and EEG during a seizure. [3]
Electroencephalogram (EEG) is also used to detect abnormal brain waves and activity that is reflected as slow waves, or spikes on the recordings. For occipital epilepsy, commonly identified abnormalities on the EEG when a seizure is not occurring (inter-ictal) includes posterior lateralized slow waves, asymmetrical alpha and photic following ...

Forced Normalization (FN) is a psychiatric phenomenon in which a long term episodic epilepsy or migraine disorder is treated, and, although the electroencephalogram (EEG) appears to have stabilized, acute behavioral, mood, and psychological disturbances begin to manifest.
