Lateral temporal lobe seizures arising from the temporal-parietal lobe junction may cause complex visual hallucinations. [2] In comparison to mesial temporal lobe seizures, lateral temporal lobe seizures are briefer duration seizures, occur with earlier loss of awareness, and are more likely become a focal to bilateral tonic-clonic seizure. [2]
Symptoms will vary according to where the seizure occurs. When seizures occur in the frontal lobe, the patient may experience a wave-like sensation in the head. When seizures occur in the temporal lobe, a feeling of déjà vu may be experienced. When seizures are localized to the parietal lobe, a numbness or tingling may occur.
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]
A seizure is a paroxysmal episode of symptoms or altered behavior arising from abnormal excessive or synchronous brain neuronal activity. [5] A focal onset seizure arises from a biological neural network within one cerebral hemisphere, while a generalized onset seizure arises from within the cerebral hemispheres rapidly involving both hemispheres.
The following definitions refer to the temporal relation with seizures. [1] Pre-ictal refers to the state immediately before the actual seizure, stroke, or headache. Post-ictal refers to the state shortly after the event. Interictal refers to the period between seizures, or convulsions, that are characteristic of an epilepsy disorder. For most ...
Seizures in the temporal lobe Geschwind syndrome , also known as Gastaut–Geschwind syndrome , is a group of behavioral phenomena evident in some people with temporal lobe epilepsy . It is named for one of the first individuals to categorize the symptoms, Norman Geschwind , who published prolifically on the topic from 1973 to 1984. [ 1 ]
A seizure is a sudden change in behavior, movement or consciousness due to abnormal electrical activity in the brain. [3] [6] Seizures can look different in different people.. It can be uncontrolled shaking of the whole body (tonic-clonic seizures) or a person spacing out for a few seconds (absence seizure
focal seizures that may spread to adjacent areas (Jacksonian seizure) grand mal or tonic-clonic seizures; changes in personality such as disinhibition, inappropriate jocularity, rage without provocation; or loss of initiative and concern, apathy, akinetic mutism, general retardation
