Temporal lobe epilepsy
Archived from the original on 22 December Long-term outcome of epilepsy surgery among patients with nonlesional seizure foci including mesial temporal lobe sclerosis. Causes and clinical features. Up to one third of patients with medial temporal lobe epilepsy will not have adequate seizure control with medication alone.
Sin embargo, pueden ser resultado de varios factores, entre ellos:. Temporal lobe epilepsy has been suggested as a physical explanation for the revelatory experiences of prominent religious figures such as AbrahamMosesJesus, MohammedSaint Pauland Joseph Smith. They may include autonomic and psychic features present in focal aware seizures. Prognosis after temporal mesail epilepsy surgery: Focal aware seizures often last less than sixty seconds; focal with impaired awareness seizures may last up to two minutes; and generalized tonic clonic seizures may last up to three minutes.
They usually begin with a focal aware seizure, then spread to a larger portion of the temporal lobe, resulting in impaired consciousness. A study inreported that intrinsic religiosity and religiosity outside of organized religion were higher in patients with epilepsy than in controls.
Clinical characteristics, epileptogenic focus in video- EEG and surgical issues were evaluated regarding to seizure recurrence during the first two postsurgical years and Engel classification in the first and second anniversary after surgery. Thadani VM, Taylor J. Tekporal say a picture paints a thousand words. Because a major function of the temporal lobe is short-term memory, a focal with impaired awareness seizure, and a focal to bilateral seizure can cause amnesia for the period of eppilepsia seizure, meaning that the seizure may not be remembered.

With this type, some people do not even realize they are having a seizure and most of the time their memory from right before or after the seizure is wiped. Surgical outcome of patients with mesial temporal lobe epilepsy related to hippocampal sclerosis.
Temporal lobe epilepsy – Wikipedia
Focal seizures in the temporal lobe involve small areas of the lobe such as the amygdala and hippocampus. They project into the hilus of the dentate gyrus and stratum lucidum in the CA3 region giving inputs to both excitatory and inhibitory neurons.
Focal impaired awareness seizures are seizures which impair consciousness to some extent: Long-term seizure outcomes following epilepsy surgery: Sudden unexpected death in epilepsy Todd’s paresis Landau-Kleffner syndrome Epilepsy in animals.
Clin Neurol Neurosurg ; Ryvlin P, Kahane P.
Declarative memory memories which can be consciously recalled is formed in the area of the hippocampus called the dentate gyrus. Though they may not seem harmful, due to the fact that the individual does not normally seize, they can be extremely harmful if the individual is left alone around dangerous objects.
Archived from the original on 4 October Long-term seizure outcome in patients initially seizure—free after resective epilepsy surgery. Ramachandran presented two subjects with neutral, sexually arousing and religious words while measuring GSR. Outcomes of epilepsy surgery in adults and children.
J Neuropathol Exp Neurol. For instance, if the dendrites of granule cells reconnect, it may be in a way through the laminar planes that allows hyperexcitability. Also, in animal models, granule cell hyper-excitability is recorded before aberrant mossy fibre sprouting has occurred. From Wikipedia, the free encyclopedia. Medicina31 3 In the TLE brain, where granule cells are damaged or lost, axons, the mossy fibres, ‘sprout’ in order to reconnect to other granule cell dendrites.
Dispersion of the granule cell layer in the hippocampal dentate gyrus is occasionally seen in temporal lobe epilepsy and has been linked to the downregulation of reelina protein that normally keeps the layer compact by containing neuronal migration.
In the mid s, human herpesvirus 6 HHV-6 was suggested as a possible causal link between febrile convulsions and mesial temporal lobe epilepsy.

Rev Neurol ; Management issues for women with epilepsy — Focus on pregnancy an evidence-based review: Most anticonvulsants function by decreasing the excitation of neuronsfor example, by blocking fast or slow sodium channels or by modulating calcium channels ; or by enhancing the inhibition of neurons, for example by potentiating the effects of inhibitory neurotransmitters like GABA. British Journal of Clinical Pharmacology. Teratogenesis and perinatal outcomes. He found a constellation of symptoms that included hypergraphiahyperreligiositycollapseand pedantismnow called Geschwind syndrome.
Acta Neurol Scand ; Aberrant mossy fibre sprouting may create excitatory feedback circuits that lead to temporal lobe seizures. TLE is usually diagnosed in childhood or adolescence. When a seizure begins in the temporal lobe, its effects depend on the precise location of its point of origin, its locus.
The existence of a “temporal lobe epileptic personality” and Geschwind syndrome has been disputed and research is inconclusive.
