Introduction: Epilepsy
Published in Candace M. Kent, David M. Chan, Analysis of a Model for Epilepsy, 2022
Candace M. Kent, David M. Chan
Common types of complex partial seizures include automatisms, in which epileptic individuals “carry out purposeful actions over which they have no conscious control or subsequent memory” [3]. Examples of automatisms are fiddling with clothes, chewing, getting up and simply walking around. Violent behavior of an epileptic individual undergoing a complex partial seizure is possible under specific scenarios such as the presence of post-ictal confusion combined with attempts to restrain the individual [3].

The most likely explanation is complex partial seizures of temporal lobe epilepsy (TLE). The features of seizures beginning in the temporal lobe vary from patient to patient in length and intensity but certain patterns are common. These auras are called simple partial seizures and occur in about three-quarters of people with TLE. They occur while consciousness is maintained. There may be a mixture of different feelings, emotions, thoughts and experiences, which may be familiar (sense of déjà vu) or completely foreign (jamais vu). Hallucinations of voices, music, people, smells or tastes may occur. A simple seizure or aura can evolve to more complex or generalized seizures, where consciousness is impaired. Auras may last for just a few seconds, or may continue as long as a minute or two. If they spread to local areas in the temporal lobes they become complex partial seizures. About 40% to 80% of people with TLE perform repetitive, automatic movements (called automatisms), such as lip smacking and rubbing the hands together. Some people have only simple partial seizures and never have a change in consciousness. In about 60% of people with TLE, the seizures spread leading to a grand mal seizure. After the complex partial seizure or secondarily generalized seizure, patients are often confused for several minutes and then gradually recover.

PTE can first occur many years postinjury.71,72 It is important to advise persons with TBI and their families about their relative risk for the development of seizures and factors that are within their control that may impact the nature of a given seizure disorder. Families should be educated as to what constitutes seizure activity. Grand mal seizures are easily recognized, and partial motor seizures may be less recognizable. Clearly, complex partial seizures are least recognizable although they constitute a surprisingly high percentage of seizure prevalence following acquired brain injury.73 Complex partial seizure disorders are difficult to diagnose and may be misinterpreted as psychiatric conditions by caregivers and professionals alike.
The Revised Definition and Classification of Epilepsy for Neurodiagnostic Technologists
Published in The Neurodiagnostic Journal, 2018
Robert S. Fisher, Anna M. Bonner
The names of the seizures have changed in a 2017 classification that revises the 1981 classification. The primary division continues to be based upon focal origin of the seizure in one hemisphere of the brain versus generalized onset in both hemispheres. Consciousness has been maintained as an important classifier of focal seizures, but awareness is used as a more easily understood surrogate marker for consciousness. The prior term “complex partial seizure” is now a “focal impaired awareness seizure.” The prior “simple partial seizure” is now a “focal aware seizure.” Focal seizures can be further subdivided into motor and nonmotor onset categories. Generalized seizures are not classified according to awareness, since awareness is impaired for most, and are categorized as either motor or absence (nonmotor) seizures. If onset is unknown, some seizures can still be classified under the heading for unknown-onset seizures.

Due to the importance of this evaluation and regarding limitations and unavailability of a human model, in this study, the kindling model of epilepsy was recruited. This model is very similar to the human complex partial seizure and is a suitable model for studying epileptogenesis (Kandratavicius et al. 2014).
