Postictal period
There is some period of recovery in which neurological function is altered after each of these seizure types. This is the postictal state. The degree and length of postictal impairment directly correlates with the severity of the seizure type. 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. The postictal state in seizures other than focal aware may last much longer than the seizure itself. 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 the seizure, meaning that the seizure may not be remembered. Complications
Depression
Individuals with temporal lobe epilepsy have a higher prevalence of depression than the general population. Although the psychosocial impacts of epilepsy may be causative, there are also links in the phenomenology and neurobiology of TLE and depression. Memory
The temporal lobe and particularly the hippocampus play an important role in memory processing. Declarative memory (memories which can be consciously recalled) is formed in the area of the hippocampus called the dentate gyrus.Temporal lobe epilepsy is associated with memory disorders and loss of memory. Animal models and clinical studies show that memory loss correlates with temporal lobe neuronal loss in temporal lobe epilepsy. Verbal memory deficit correlates with pyramidal cell loss in TLE. This is more so on the left in verbal memory loss.
Ramachandran was able to show that patients with TLE showed enhanced emotional responses to the religious words, diminished responses to the sexually charged words, and normal responses to the neutral words. This study was presented as an abstract at a neuroscience conference and referenced in Ramachandrans book, Phantoms in the Brain, but it has never been published in the peer-reviewed scientific press.A study in 2015, reported that intrinsic religiosity and religiosity outside of organized religion were higher in patients with epilepsy than in controls. Lower education level, abnormal background EEG activity, and hippocampal sclerosis have been found to be contributing factors for religiosity in TLE.TLE has been suggested as a materialistic explanation for the revelatory experiences of prominent religious figures such as Abraham, Moses, Jesus, Mohammed, Saint Paul, Joan of Arc, Saint Teresa of Ávila, and Joseph Smith. These experiences are described (in possibly unreliable accounts) as complex interactions with their visions; but possibly (and dependent on the reliability of historical accounts, often made by acolytes) lack the stereotypy, amnestic periods, and automatisms or generalized motor events, which are characteristic of TLE. Psychiatric conditions with psychotic spectrum symptoms might be more plausible physical explanation of these experiences. It has been suggested that Pope Pius IXs doctrine of the immaculate conception was influenced by his forensically diagnosed partial epilepsy.In 2016, a case history found that a male temporal lobe epileptic patient experienced a vision of God following a temporal lobe seizure, while undergoing EEG monitoring.
