temporal lobe seizure


Also found in: Dictionary, Thesaurus.

temporal lobe seizure

A simple or complex seizure caused by abnormal electrical activity in the temporal lobes, which may result in transient changes in movement, sensation, autonomic function, alertness and awareness.
 
Clinical findings
Temporary paralysis, sleep paralysis, fear sensation, hallucinations (e.g., delusion of lycanthropy, or misinterpreted as UFO abductions). Temporal lobe seizures may occur in anyone at any age, as a single episode, or as a chronic seizure disorder.
 
Diagnosis
Abnormal electrical activity on EEG.
 
Aetiology
Temporal lobe damage (trauma, hypoxia), ischaemia and/or infarction, tumours, infection or any other discrete lesion.

Management
Phenytoin, phenobarbital, carbamazepine, valproate.

Although temporal lobe seizures are fairly well controlled with surgery, removal of both temporal lobes is associated with significantly higher morbidity (e.g., inability to form new memories after surgery but with preserved old memories) and is therefore not typically done (Harroud, Bouthillier, Weil, & Nguyen, 2012).
Temporal lobe seizures can present with waves of anxiety and depersonalization.
When these imitation temporal lobe seizures were "played back" into the temporal lobes of volunteers by using magnetic solenoids built into a helmet, the person experienced one or several of the Joan of Arc type of phenomena.
Neuroimaging is an integral part of the preoperative evaluation of patients with intractable temporal lobe seizures. Many patients with temporal lobe epilepsy have mesial temporal sclerosis, characterized by hippocampal atrophy secondary to neuronal loss and gliosis that can be visualized on high-resolution MR scans.
Of the remaining 32.3%, temporal lobe seizures accounted for 27.4% (Absence seizures-8.3%; Complex partial seizures-13.3%; Simple partial seizure-5.8%-i.e.
