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.

In newly diagnosed epilepsy, magnetic resonance imaging (MRI) can detect brain lesion in up to 12 to 14% of persons with epilepsy. [31] However, for those with chronic epilepsy, MRI can detect brain lesion in 80% of the persons with epilepsy. [31] 3-Tesla MRI scan is advised for those with evidence of focal epilepsy such as temporal lobe ...
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 part of the olfactory cortex that is on the temporal lobe covers the area of the uncus, which leads into the two significant clinical aspects: herniations and seizures Herniations of the brain can occur if increased intracranial pressure due to a tumor, hemorrhage, or edema pushes the uncus over the tentorial notch against the brainstem and ...
[133] [134] It is not yet clear, however, whether the epilepsy is usually caused by hippocampal abnormalities or whether the hippocampus is damaged by cumulative effects of seizures. [135] However, in experimental settings where repetitive seizures are artificially induced in animals, hippocampal damage is a frequent result.

Information about the structure and function of the human brain comes from a variety of experimental methods, including animals and humans. Information about brain trauma and stroke has provided information about the function of parts of the brain and the effects of brain damage. Neuroimaging is used to visualise the brain and record brain ...
