Neurology, Psychiatry. In the field of neurology, temporal lobe epilepsy is an enduring brain disorder that causes unprovoked seizures from the temporal lobe. Temporal lobe epilepsy is the most common type of focal onset epilepsy among adults. [1] Seizure symptoms and behavior distinguish seizures arising from the medial temporal lobe from ...
A brain injury can cause seizure(s) because of the unusual amount of energy that is discharged across of the brain when the injury occurs and thereafter. A disruption of the supply of oxygen may cause damage to the temporal lobe of the brain. [35] The risk of seizure(s) from a closed head injury is about 15%. [36]
Status epilepticus (SE), or status seizure, is a medical condition consisting of a single seizure lasting more than 5 minutes, or 2 or more seizures within a 5-minute period without the person returning to normal between them. [3][1] Previous definitions used a 30-minute time limit. [2] The seizures can be of the tonic–clonic type, with a ...
The risk of sudden death in young adults with epilepsy is increased 20-40-fold compared to the general population. [31] [32] [19] SUDEP is the number one cause of epilepsy-related death in people with pharmacoresistant epilepsy. [19] Children with epilepsy have a cumulative risk of dying suddenly of 7% within 40 years. [19]
In addition, the chances of developing PTE differ by the location of the brain lesion: brain contusion that occurs on in one or the other of the frontal lobes has been found to carry a 20% PTE risk, while a contusion in one of the parietal lobes carries a 19% risk and one in a temporal lobe carries a 16% chance. [22]
Deaths. 140,000 (2021) [ 9 ] Epilepsy is a group of non-communicable neurological disorders characterized by recurrent epileptic seizures. [ 10 ] An epileptic seizure is the clinical manifestation of an abnormal, excessive, and synchronized electrical discharge in the neurons. [ 1 ] The occurrence of two or more unprovoked seizures defines ...
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]
Reflex seizure. Reflex seizures are epileptic seizures that are consistently induced by a specific stimulus or trigger, making them distinct from other epileptic seizures, which are usually unprovoked. [4][3] Reflex seizures are otherwise similar to unprovoked seizures and may be focal (simple or complex), generalized, myoclonic, or absence ...
