Epilepsy is a neurological condition of recurrent episodes of unprovoked epileptic seizures. A seizure is an abnormal neuronal brain activity that can cause intellectual, emotional, and social consequences. Epilepsy affects children and adults of all ages and races, and is one of the most common neurological disorders of the nervous system. [1]
PNES episodes can be difficult to distinguish from epileptic seizures without the use of long-term video EEG monitoring.Some characteristics which may distinguish PNES from epileptic seizures include gradual onset, out-of-phase limb movement (in which left and right extremities jerk asynchronously or in opposite directions, as opposed to rhythmically and simultaneously as in epileptic seizures ...
Systemic infection with high fever is a common cause of seizures, especially in children. [3] [25] These are called febrile seizures and occur in 2–5% of children between the ages of six months and five years. [26] [25] Acute infection of the brain, such as encephalitis or meningitis are also causes of seizures. [3]
Vitamin B12 deficiency was reported to be the cause of seizures for adults [9] [10] and for infants. [11] [12] Folic acid in large amounts was considered to potentially counteract the antiseizure effects of antiepileptic drugs and increase the seizure frequency in some children, although that concern is no longer held by epileptologists. [13]
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 ...
Identifying an epilepsy syndrome is useful as it helps determine the underlying causes as well as what anti-seizure medication should be tried. [30] [114] The ability to categorize a case of epilepsy into a specific syndrome occurs more often with children since the onset of seizures is commonly early. [69]
Absence seizures are also known to occur to patients with porphyria and can be triggered by stress or other porphyrin-inducing factors. Childhood Absence Epilepsy. Childhood absence epilepsy (CAE) is a type of idiopathic epilepsy characterized by its non-convulsive, generalized nature and a genetic origin influenced by multiple factors [20]
The first generalized tonic–clonic seizure usually occurs in the context of a particular provoking factor, such as sleep deprivation, stress or alcohol consumption. [15] Other potential provoking factors include "praxis induction" which is the precipitation of seizures or epileptiform discharges in the context of a complex cognitive tasks. [ 16 ]
