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]
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]
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]
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.
Temporal lobe epilepsy is a chronic neurological condition characterized by recurrent seizures; symptoms include a variety of sensory (visual, auditory, olfactory, and gustation) hallucinations, as well as an inability to process semantic and episodic memories. [24] Schizophrenia is a severe psychotic disorder characterized by severe ...
Abdominal aura is a common type of epileptic aura, and it is very common in temporal lobe epilepsy compared to extratemporal focal epilepsies. [3] In one study, more than half of patients with temporal lobe epilepsy experienced abdominal aura, and most of those cases of abdominal aura evolved into a generalized motor seizure .
Epilepsies in the parietal and occipital lobes commonly propagate into the temporal lobe inducing a vertiginous state. [2] This electrical propagation across the brain explains why so many different symptoms may be associated with the vertiginous seizure.
Spread to produce symptoms of temporal lobe involvement is exceptional and may indicate a symptomatic cause. [ citation needed ] Post-ictal headache , mainly diffuse, but also severe, unilateral and pulsating, or indistinguishable from migraine headache , occurs in half the patients, in 10% of whom it may be associated with nausea and vomiting.
