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]
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.

Childhood absence epilepsy (CAE), formerly known as pyknolepsy, is an idiopathic generalized epilepsy which occurs in otherwise normal children. The age of onset is between 4–10 years with peak age between 5–7 years. Children have absence seizures which although brief (~4–20 seconds), they occur frequently, sometimes in the hundreds per ...

The seizures can be of the tonic–clonic type, with a regular pattern of contraction and extension of the arms and legs, or of types that do not involve contractions, such as absence seizures or complex partial seizures. [1] Status epilepticus is a life-threatening medical emergency, particularly if treatment is delayed. [1]
Epilepsy is more common among children than adults, affecting about 6 out of 1000 US children that are between the age of 0 to 5 years old. [2] The epileptic seizures can be of different types depending on the part of the brain that was affected, seizures are classified in 2 main types partial seizure or generalized seizure. [1]

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.
