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 ...
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.
[3] [7] If it is a person's first seizure and it was "provoked", or caused by another condition, treatment of the cause is usually enough to treat the seizure. [3] If the seizure is "unprovoked", brain imaging is abnormal, and/or EEG is abnormal, starting anti-seizure medications is generally recommended. [3] [7] [14]
Some clinical factors that are thought to be predictive of DRE include the female sex, focal epilepsy, developmental delay, status epilepticus, earlier age of onset of epilepsy, neurological deficits, having an abnormal EEG and/or imaging findings, genetic predisposition, association with the ABCB1 gene, and inborn errors of metabolism.
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.
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.
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]
One example that is commonly diagnosed as treatment is carbamazepine. This drug works to block voltage-dependent sodium channels, making fewer available to open. [ 11 ] Although not very widely performed or well researched for many patients with occipital epilepsy, surgical intervention to remove the area with seizure activity is also an option ...
