Lateral temporal lobe seizures arising from the temporal-parietal lobe junction may cause complex visual hallucinations. [2] In comparison to mesial temporal lobe seizures, lateral temporal lobe seizures are briefer duration seizures, occur with earlier loss of awareness, and are more likely become a focal to bilateral tonic-clonic seizure. [2]
However, the "reason for the close relationship of TEA with sleep is unclear. It may be that the transition from sleep to waking acts as a trigger to a seizure focus in the medial temporal lobe. Alternatively, amnesia upon waking may reflect persistent post-ictal dysfunction of medial temporal lobe structures following a seizure during sleep." [2]
Status epilepticus (SE), or status seizure, is a medical condition with abnormally prolonged seizures.It can have long-term consequences, [3] manifesting as a single seizure lasting more than a defined time (time point 1), or 2 or more seizures over the same period without the person returning to normal between them.
Focal seizures (also called partial seizures [1] and localized seizures) are seizures that affect initially only one hemisphere of the brain. [2] [3] The brain is divided into two hemispheres, each consisting of four lobes – the frontal, temporal, parietal and occipital lobes. A focal seizure is generated in and affects just one part of the ...
MRIs are used to look for masses or lesions in the temporal lobe of the brain, indicating possible tumors or cancer as the cause of the seizures. [2] When using a PET scan, a physician is looking to detect abnormal blood flow and glucose metabolism in the brain, which is visible between seizures, to indicate the region of origin.
The temporal lobes, and the hypothalamus are the areas of the brain with the most involvement with these seizures. This may cause learning disabilities, and faulted cognitive function as well. [citation needed] It is not uncommon for children to have tonic–clonic seizures, and atonic seizures directly following the seizure. Those that are ...
