  2. Absence seizure - Wikipedia

    en.wikipedia.org/wiki/Absence_seizure

    However, if an individual suffers an absence seizure while driving or operating dangerous machinery, a fatal accident may occur. [5] Absence seizures affect between 0.7 and 4.6 per 100,000 in the general population and 6 to 8 per 100,000 in children younger than 15 years. Childhood absence seizures account for 10% to 17% of all absence seizures.

  3. Spike-and-wave - Wikipedia

    en.wikipedia.org/wiki/Spike-and-wave

    A drawing of the human brain showing the thalamus and cortex relative to other structures. The spike-and-wave pattern seen during an absence seizure is the result of a bilateral synchronous firing of neurons ranging from the neocortex (part of the cerebral cortex) to the thalamus, along the thalamocortical network. [2]

  4. Aura (symptom) - Wikipedia

    en.wikipedia.org/wiki/Aura_(symptom)

    An epileptic aura is actually a minor seizure. [1] Epileptic and migraine auras are due to the involvement of specific areas of the brain, which are those that determine the symptoms of the aura. Therefore, if the visual area is affected, the aura will consist of visual symptoms, while if a sensory one, then sensory symptoms will occur.

  5. Childhood absence epilepsy - Wikipedia

    en.wikipedia.org/wiki/Childhood_absence_epilepsy

    In CAE, there is only one seizure type observed at time of diagnosis: typical absence seizure. [1] Typical absence seizure is a generalized onset seizure characterized by an abrupt arrest of the activity associated with an awareness impairment. A typical absences seizure usually last between 10 and 30 seconds. [3] Mild automatisms could be seen ...

  6. Epilepsy syndromes - Wikipedia

    en.wikipedia.org/wiki/Epilepsy_syndromes

    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 ...

  7. Juvenile myoclonic epilepsy - Wikipedia

    en.wikipedia.org/wiki/Juvenile_myoclonic_epilepsy

    The majority of patients (58.2%) have frequent myoclonic jerks, [13] with some sources stating that all patients with JME have myoclonic seizures. [10] Generalized tonic–clonic seizures are less common [13] but still reported in 85–90%. [10] Absence seizures are believed to be least common, with an estimated prevalence between 10% and 40%.

  8. Status epilepticus - Wikipedia

    en.wikipedia.org/wiki/Status_epilepticus

    It is of two main types with either prolonged complex partial seizures or absence seizures. [11] Up to a quarter of cases of SE are nonconvulsive. [11] In the case of complex partial status epilepticus, the seizure is confined to a small area of the brain, normally the temporal lobe. Absence status epilepticus is marked by a generalized seizure ...

  9. Epilepsy in children - Wikipedia

    en.wikipedia.org/wiki/Epilepsy_in_children

    The location of the brain from which the seizures originate, known as the epileptogenic zone, is disconnected to minimize, or even stop, occurrence of seizures and its complications. [45] A significant reduction in seizures is seen with most hemispherectomy or hemispherotomy procedures, with more than half resulting in a seizure-free outcome.
