It is not uncommon for an individual to be tired or confused for up to 15 minutes after a seizure has occurred, although postictal confusion can last for hours or even days. 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. For example, if a person with complex partial seizures is driving alone, this can cause them to run into the ditch, or worse, cause an accident involving multiple people. With this type, some people do not even realize they are having a seizure and most of the time their memory from right before to after the seizure is wiped. First-aid is only required if there has been an injury or if this is the first time a person has had a seizure. Focal to bilateral seizures or generalized seizures
Seizures which begin in the temporal lobe, and then spread to involve both sides of the brain are termed focal to bilateral. Where both sides of the brain or the whole brain are involved from the onset, these seizures are known as generalized seizures and may be tonic clonic. The arms, trunk, and legs stiffen (the tonic phase), in either a flexed or extended position, and then jerk (the clonic phase). These were previously known as grand mal seizures. The word grand mal comes from the French term, meaning major affliction.
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.
