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.
In focal onset aware seizures, a small part of one of the lobes may be affected and the person remains conscious. This can often be a precursor to a larger focal onset impaired awareness seizure; in such cases, the focal aware seizure is usually called an aura. A focal impaired awareness seizure affects a larger part of the hemisphere and the ...
Ohtahara syndrome (OS), also known as Early Infantile Developmental & Epileptic Encephalopathy (EIDEE) [2] is a progressive epileptic encephalopathy.The syndrome is outwardly characterized by tonic spasms and partial seizures within the first few months of life, [3] and receives its more elaborate name from the pattern of burst activity on an electroencephalogram (EEG).
Panayiotopoulos syndrome and all other benign childhood focal seizures, with rolandic epilepsy as their main representative, are probably linked due to a common, genetically determined, mild, and reversible functional derangement of the brain cortical maturational process that Panayiotopoulos proposed as "benign childhood seizure susceptibility ...
Benign Rolandic epilepsy or self-limited epilepsy with centrotemporal spikes (formerly benign childhood epilepsy with centrotemporal spikes (BECTS)) is the most common epilepsy syndrome in childhood. [ 1 ] [ 2 ] Most children will outgrow the syndrome (it starts around the age of 3–13 with a peak around 8–9 years and stops around age 14 ...
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.
Absence seizures are believed to be least common, with an estimated prevalence between 10% and 40%. [13] [10] [14] Seizures associated with JME tend to take place 30 minutes to an hour after waking up in the morning. [10] Common triggers for JME seizures include lack of sleep, alcohol consumption, emotional stress, anxiety, and fatigue.
Focal neurological deficits may be caused by a variety of medical conditions such as head trauma, [1] tumors or stroke; or by various diseases such as meningitis or encephalitis or as a side effect of certain medications such as those used in anesthesia. [2] Neurological soft signs are a group of non-focal neurologic signs. [3]
