Do temporal lobe epilepsies often result in heavenly visions.?

Question

This is a very interesting question. Is our mind playing tricks on us? Is Religion a Biological conundrum? Is the only difference between a Homosexual and a Christian just a few misplaced synapses?

Answer 1

This has been well documented, and there is a strong correlation between people with temporal lobe epilepsy and extreme religiosity.

Answer 2

This is an interesting question. I've read a little bit about it, but would like to find more info.

One of the things I've read, is that what you see will depend on your cultural background, what you were taught in your formative years, etc. But I wonder, what of those who see something completely different from these influences? For example, white american raised in xtian backgroud, seeing Hecate.

Answer 3

I have epilepsy. I've never had a vision.

Answer 4

Background: Temporal lobe epilepsy (TLE) was defined in 1985 by the International League Against Epilepsy (ILAE) as a condition characterized by recurrent unprovoked seizures originating from the medial or lateral temporal lobe. The seizures associated with TLE consist of simple partial seizures without loss of awareness (with or without aura) and complex partial seizures (ie, with loss of awareness). The individual loses awareness during a complex partial seizure because the seizure spreads to involve both temporal lobes, which causes impairment of memory.

TLE was first recognized in 1881 by John Hughlings Jackson, who described "uncinate fits" seizures arising from the uncal part of temporal lobe and the “dreamy state." In the 1940s, Gibbs et al introduced the term "psychomotor epilepsy." The international classification of epileptic seizures (1981) replaced the term psychomotor seizures with complex partial seizures. The ILAE classification of the epilepsies uses the term temporal lobe epilepsy and divides the etiologies into cryptogenic (presumed unidentified etiology), idiopathic (genetic), and symptomatic (cause known, eg, tumor).


Pathophysiology: Hippocampal sclerosis is the most common pathologic finding in TLE. Hippocampal sclerosis involves hippocampal cell loss in the CA1 and CA3 regions and the dentate hilus. The CA2 region is relatively spared. The clinical correlate on neuroimaging on MRI is called mesial temporal lobe sclerosis.

For more information, see Pathophysiology in the article Seizures and Epilepsy: Overview and Classification.


Frequency:


In the US: Approximately 50% of patients with epilepsy have partial epilepsy. Partial epilepsy is often of temporal lobe origin. However, the true prevalence of TLE is not known, since not all cases of presumed TLE are confirmed by video-EEG and most cases are classified by clinical history and interictal EEG findings alone. The temporal lobe is the most epileptogenic region of the brain. In fact, 90% of patients with temporal interictal epileptiform abnormalities on their EEG have a history of seizures.
Age: Epilepsy occurs in all age groups, but a group where it was underrecognized is in elderly persons. Epilepsy in elderly persons may not be as dramatic and often may present as confusion or memory lapses. The index for suspicion should be low as patients are often misdiagnosed and not treated appropriately.


History:

Aura
Auras occur in approximately 80% of temporal lobe seizures. They are a common feature of simple partial seizures and usually precede complex partial seizures of temporal lobe origin.
Auras may be classified by symptom type; the types comprise somatosensory, special sensory, autonomic, or psychic symptoms.
Somatosensory and special sensory phenomena
Olfactory and gustatory illusions and hallucinations may occur. Acharya et al found that olfactory auras are associated more commonly with temporal lobe tumors than with other causes of TLE.
Auditory hallucinations consist of a buzzing sound, a voice or voices, or muffling of ambient sounds. This type of aura is more common with neocortical TLE than with other types of TLE.
Patients may report distortions of shape, size, and distance of objects.
These visual illusions are unlike the visual hallucinations associated with occipital lobe seizure in that no formed elementary visual image is noted, such as the visual image of a face that may be seen with seizures arising from the fusiform or the inferior temporal gyrus.
Things may appear shrunken (micropsia) or larger (macropsia) than usual.
Tilting of structures has been reported. Vertigo has been described with seizures in the posterior superior temporal gyrus.
Psychic phenomena
Patients may have a feeling of déjà vu or jamais vu, a sense of familiarity or unfamiliarity, respectively.
Patients may experience depersonalization (ie, feeling of detachment from oneself) or derealization (ie, surroundings appear unreal).
Fear or anxiety usually is associated with seizures arising from the amygdala. Sometimes, the fear is strong, described as an "impending sense of doom."
Patients may describe a sense of dissociation or autoscopy, in which they report seeing their own body from outside.
Autonomic phenomena are characterized by changes in heart rate, piloerection, and sweating. Patients may experience an epigastric "rising" sensation or nausea.
Physical:

Following the aura, a temporal lobe complex partial seizure begins with a wide-eyed, motionless stare, dilated pupils, and behavioral arrest. Oral alimentary automatisms such as lip smacking, chewing, and swallowing may be noted. Manual automatisms or unilateral dystonic posturing of a limb also may be observed.
Patients may continue their ongoing motor activity or react to their surroundings in a semipurposeful manner (ie, reactive automatisms). They can have repetitive stereotyped manual automatisms.
A complex partial seizure may evolve to a secondarily generalized tonic-clonic seizure. Often, the documentation of a seizure only notes the generalized tonic-clonic component of the seizure. A careful history from the patient or an observer is needed to elicit the partial features of either a simple seizure or a complex partial seizure before the secondarily generalized seizure is important.
Patients usually experience a postictal period of confusion, which distinguishes TLE from absence seizures, which are not associated with postictal confusion. In addition, absence seizures are not associated with auras nor with complex automatisms. Postictal aphasia suggests onset in the language-dominant temporal lobe.
Most auras and automatisms last a very short period—seconds or 1-2 minutes. The postictal phase may last for a longer period (several minutes). By definition, amnesia occurs during a complex partial seizure because of bilateral hemispheric involvement.
Causes:

Approximately two thirds of patients with TLE treated surgically have hippocampal sclerosis as the pathologic substrate.
The etiologies of TLE include the following:
Infections, eg, herpes encephalitis, bacterial meningitis, neurocysticercosis
Trauma producing contusion or hemorrhage that results in encephalomalacia or cortical scarring; difficult traumatic delivery such as forceps deliveries
Hamartomas
Malignancies (eg, meningiomas, gliomas, gangliomas)
Vascular malformations (ie, arteriovenous malformation, cavernous angioma)
Cryptogenic: A cause is presumed but has not been identified.
Idiopathic (genetic): This is rare. Familial TLE was described by Berkovic and colleagues, and partial epilepsy with auditory features was described by Scheffer and colleagues.
Hippocampal sclerosis produces a clinical syndrome called mesial temporal lobe epilepsy (MTLE).
Febrile seizures: The association of simple febrile seizure with TLE has been controversial. However, a subset of children with complex febrile convulsions appear to be at risk of developing TLE in later life. Complex febrile seizures are febrile seizures that last longer than 15 minutes, have focal features, or recur within 24 hours.
