Knowra Temporal lobe epilepsy Temporal lobe epilepsy Temporal lobe epilepsy is focal epilepsy in which seizures begin in one or both temporal lobes. Seizures may involve altered awareness, memory, emotion, or sensory experience.
Focal seizure : A seizure that begins in networks on one side of the brain. Temporal lobe epilepsy is a focal epilepsy, with seizure onset localized to temporal-lobe networks.
Video-EEG monitoring : Simultaneous video recording and EEG used to characterize seizures over time. Capturing habitual events helps distinguish temporal-lobe seizures from similar episodes and locate their onset.
Absence seizure : A generalized seizure causing brief, abrupt lapses in awareness, often with staring. Unlike temporal-lobe seizures, absence seizures begin across bilateral networks rather than a focal temporal region.
Epilepsy and memory : The effects of epilepsy and its treatment on memory formation, storage, and recall. Temporal-lobe structures support memory, so seizures or associated injury can impair it.
Hippocampus : A brain structure central to forming memories and spatial navigation. The hippocampus is a frequent site of structural abnormalities associated with temporal-lobe seizure onset.
Magnetic resonance imaging : An imaging technique that uses magnetic fields and radio waves to produce detailed body images. Epilepsy-protocol MRI can reveal hippocampal sclerosis or other temporal-lobe lesions.
Psychogenic nonepileptic seizure : An episode resembling an epileptic seizure but not caused by epileptic brain activity. These episodes can resemble focal seizures, making careful video-EEG evaluation useful.
Sudden unexpected death in epilepsy : A sudden, unexpected death in a person with epilepsy without an identified alternative cause. It is a rare but serious risk associated especially with uncontrolled convulsive seizures.
Mesial temporal sclerosis : Scarring and neuronal loss in medial temporal structures, especially the hippocampus. This common pathology can underlie drug-resistant temporal lobe epilepsy.
Antiseizure medication : Medication used to reduce or prevent epileptic seizures. Medication is usually the initial treatment for temporal-lobe epilepsy.
