What is temporal pole?
The temporal pole is an anatomical landmark that corresponds to the anterior end of the temporal lobe, lying in the middle cranial fossa.
Why is the temporal lobe prone to seizures?
Experts say some possible causes of temporal lobe seizures include: severe traumatic brain injury. infections or a history of infections like meningitis or encephalitis. scarring (gliosis) in the hippocampus part of the temporal lobe.
Which of the following are typical symptoms of a partial seizure in the temporal lobe?
- A sudden sense of unprovoked fear or joy.
- A deja vu experience — a feeling that what’s happening has happened before.
- A sudden or strange odor or taste.
- A rising sensation in the abdomen, similar to being on a roller coaster.
What is the left temporal pole?
The left temporal pole is a convergence region mediating the relation between names and semantic knowledge for unique entities: Further evidence from a “recognition-from-name” study in neurological patients. Cortex. 2018 Dec;109:14-24.
Can stress cause temporal lobe seizures?
Temporal lobe epilepsy is a disease of faulty neuronal resonators rather than oscillators, and all seizures are provoked, usually by stress.
Do temporal lobe seizures show up EEG?
An EEG (electroencephalogram) should be done and often shows spike or sharp waves in the tip or front of the temporal lobe. These can be seen when a person is awake or asleep. When seizures arise in more mesial (middle) temporal lobe areas, the EEG may only show rhythmic slowing during seizures.
What disorders are associated with the temporal lobe?
Kolb & Wishaw (1990) have identified eight principle symptoms of temporal lobe damage: 1) disturbance of auditory sensation and perception, 2) disturbance of selective attention of auditory and visual input, 3) disorders of visual perception, 4) impaired organization and categorization of verbal material, 5) …
Can a temporal lobectomy help with temporal lobe epilepsy?
The most common and well-characterized focal epilepsy syndrome is medial (mesial) temporal lobe epilepsy (MTLE). For patients with intractable MTLE, an anterior temporal lobectomy and amygdalohippocampectomy (ATL) offers the possibility of seizure freedom with reduced reliance on antiepileptic medications.
What are the effects of mesial temporal sclerosis?
Typical findings of mesial temporal sclerosis are hippocampal atrophy and increased FLAIR and T2 signal hyperintensity in the medial temporal lobe structures. Hippocampal atrophy on preoperative MR imaging is associated with improved seizure control following temporal lobectomy.
What kind of anesthetic is used for temporal lobectomy?
Amobarbital or another anesthetic agent, such as methohexital, propofol, or etomidate, is injected into the internal carotid artery, temporarily suppressing function on that side while language and memory tests are performed. Baseline memory function is typically tested the day before the actual test.
