Juvenile Myoclonic Epilepsy (JME), also referred to as Janz Syndrome and Impulsive Petit Mal, is a form of epilepsy that is characterized by absence, Myoclonic, and Generalized Tonic-Clonic Seizures. This epilepsy variant is marked by its idiopathic and hereditary characteristics, as well as its generalization across seizures.
There are three principal seizure types which may occur in JME: myoclonus, generalized tonic–clonic seizures and absence seizures. Approximately one-third of patients have all three seizure types. [13] The majority of patients (58.2%) have frequent myoclonic jerks, [13] with some sources stating that all patients with JME have myoclonic ...
A spike-and-wave discharge is a regular, symmetrical, generalized EEG pattern seen particularly during absence epilepsy, also known as ‘petit mal’ epilepsy. [1] The basic mechanisms underlying these patterns are complex and involve part of the cerebral cortex , the thalamocortical network , and intrinsic neuronal mechanisms.
Seizures are among its most serious symptoms, which can escalate into a coma. Other symptoms include confusion (which Shields experienced), muscle cramps or weakness, nausea, lethargy, and headache.
The epileptic seizure in the vast majority of pediatric epilepsy patients is ephemeral, and symptoms typically subside on their own after the seizure comes to an end, but some children experience what is known as a “seizure cluster," in which the first seizure is followed by a second episode approximately six hours later.
This one was a tonic-clonic seizure, formerly known as a "grand mal" seizure. To the general public, it's the 'big one' characterized by muscle stiffening and jerking, loss of consciousness and ...
Brooke Shields overhydrated herself into a “full-blown grand mal seizure” in September before the opening of her one-woman show in New York City, the renowned actress told Glamour this week.
A seizure is a paroxysmal episode of symptoms or altered behavior arising from abnormal excessive or synchronous brain neuronal activity. [5] A focal onset seizure arises from a biological neural network within one cerebral hemisphere, while a generalized onset seizure arises from within the cerebral hemispheres rapidly involving both hemispheres.
