A simple febrile seizure is generalized, occurs singularly, and lasts less than 15 minutes. [19] A complex febrile seizure can be focused in an area of the body, occur more than once, and lasts for more than 15 minutes. [19] Febrile seizures affect 2–4% of children in the United States and Western Europe, it is the most common childhood ...
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.
A seizure is a sudden change in behavior, movement and/or consciousness due to abnormal electrical activity in the brain. [3] [6] Seizures can look different in different people. It can be uncontrolled shaking of the whole body (tonic-clonic seizures) or a person spacing out for a few seconds (absence seizures).
Epilepsy is a group of non-communicable neurological disorders characterized by recurrent epileptic seizures. [10] An epileptic seizure is the clinical manifestation of an abnormal, excessive, and synchronized electrical discharge in the neurons. [1]
The most characteristic seizure type is a tonic seizure, which consists of brief generalized body stiffening, and often occurs most prominently in sleep. Additionally, patients often have other seizures types including atonic (abrupt, brief events of loss of tone, often leading to falls), atypical absences (staring spells with more gradual ...
Tonic-clonic seizures: seizures with repetitive sequences of stiffening and jerking of the extremities. Myoclonic seizures: seizures with rapid, brief contractions of muscles. Atonic seizures: seizures with a sudden loss of muscle tone, often resulting in sudden collapse. These are also called drop seizures or astatic seizures.

Generalized epilepsy is a form of epilepsy characterised by generalised seizures with no apparent cause. [1] Generalized seizures, as opposed to focal seizures, are a type of seizure that impairs consciousness and distorts the electrical activity of the whole or a larger portion of the brain (which can be seen, for example, on electroencephalography, EEG).
