OBJECTIVE Dèjà-vù (DV) can occur as a seizure of mesial temporal lobe epilepsy (MTLE) and in almost 80% of healthy individuals. The remarkable similarity between epileptic DV and DV in healthy individuals raises the possibility that DV might sometimes be an ictal phenomenon in apparently normal individuals. Thus, we studied a group of healthy subjects versus individuals with benign MTLE (bMTLE) both experiencing DV. METHODS 63 individuals with epilepsy patients with bMTLE and 39 healthy… Expand
Neuroimaging methods in Epilepsy of Temporal Origin.
TLDR
Advanced MRI, SPECT, and PET imaging techniques are increasingly becoming an essential part of TLE diagnostics, when the epileptogenic area is not identified on structural MRI or when structural MRI, clinical, and electrophysiological findings are not in concordance. Expand
Functional activity changes in memory and emotional systems of healthy subjects with déjà vu
TLDR
This study demonstrates that individuals who experienced DV are not characterized by different performance underlying familiarity/recollection memory processes, and fMRI results provide evidence that the physiological DV experience is associated with the employment of different neural responses of brain regions involved in memory and emotional processes. Expand
Hippocampal involvement in nonpathological déjà vu: Subfield vulnerability rather than temporal lobe epilepsy equivalent
TLDR
The hypothesis that hippocampal involvement in nonpathological DV resembles more closely the pattern of GMV decrease observed in MTLE compared with that occurring in SCH is tested. Expand
Utilization of brain imaging in evaluating patients with psychogenic nonepileptic spells
TLDR
It is suggested that the frequency of brain imaging obtained prior to the definitive diagnosis of PNES is influenced by semiology of spells and the psychiatric health of patients. Expand
Structural covariance mapping delineates medial and medio-lateral temporal networks in déjà vu
TLDR
The present study assessed whether grey-matter covariance among structures implicated in non-pathological DV differs according to the frequency with which the phenomenon is experienced, and revealed two diverging patterns of structural covariation. Expand
Abnormal rsFC and GMV changes in parahippocampal and DLPFC for high Déjà vu experienced subjects
TLDR
Findings indicated that familiarity without recollection (PHG) and superior context monitoring (DLPFC) are critical for real-life déjà vu experiences. Expand
Déjà vu and prescience in a case of severe episodic amnesia following bilateral hippocampal lesions
TLDR
This study shows that déjà vu can occur in cases of amnesia with massively damaged hippocampi and confirms that the perirhinal region is a core region for déjé vu, using a different approach from previous reports. Expand
Insight into epileptic and physiological déjà vu: from a multicentric cohort study
TLDR
The aim was to identify the epidemiological distribution of DV in Italy, and secondly to look for specific features of DV able to discriminate between epileptic and non‐epileptic DV. Expand
Validation Study of Italian Version of Inventory for Déjà Vu Experiences Assessment (I-IDEA): A Screening Tool to Detect Déjà Vu Phenomenon in Italian Healthy Individuals
TLDR
The Italian version of IDEA maintains good properties, thus confirming that this instrument is reliable for detecting and characterising the DV phenomenon. Expand
Déjà vu experiences in anxiety
TLDR
There are differences in déjà vu experienced by people reporting high levels of anxiety compared to healthy controls without an anxiety diagnosis, and structural and neural mechanisms thought to underpin déjaa vu are discussed. Expand

Déjà-vu in temporal lobe epilepsy: Metabolic pattern of cortical involvement in patients with normal brain MRI
TLDR
Findings argue for metabolic dysfunction of a medial-lateral temporal network in patients with déjà-vu and normal brain MRI and suggest that the feeling of familiarity during seizures greatly depends on alteration of the recognition memory system. Expand
Is there anything distinctive about epileptic déjà vu?
Background Déjà vu can occur as an aura of temporal lobe epilepsy and in some psychiatric conditions but is also common in the general population. It is unclear whether any clinical featuresExpand
MRI evidence of mesial temporal sclerosis in sporadic “benign” temporal lobe epilepsy
TLDR
MRI-detected mesial temporal sclerosis is often encountered in patients with sporadic benign temporal lobe epilepsy, and correlated with the epileptiform activity. Expand
Hippocampal and thalamic atrophy in mild temporal lobe epilepsy
TLDR
The structural abnormalities seen in patients with mild temporal lobe epilepsy (TLE) demonstrate that a temporo-limbic pathway, which includes the thalamus, plays a major role in the pathogenesis of TLE. Expand
Unveiling the mystery of déjà vu: The structural anatomy of déjà vu
TLDR
A structural correlate of DV in healthy individuals for the first time is demonstrated and it is hypothesized that the observed local gray matter decrease in subjects experiencing DV reflects an alteration of hippocampal function and postnatal neurogenesis with resulting changes of volume in remote brain regions. Expand
Anatomical origin of déjà vu and vivid 'memories' in human temporal lobe epilepsy.
TLDR
The mental phenomena observed in epileptic patients with electrodes stereotaxically implanted into different brain areas for seizure localization prior to surgical treatment is considered, finding that the amygdala was involved in 73% of cases, the anterior hippocampus in 83% and the temporal neocortex in 88%.

Advanced MRI Morphologic Study Shows No Atrophy in Healthy Individuals with Hippocampal Hyperintensity
TLDR
It was clearly showed that Hh is not associated with any occult brain atrophy; furthermore, none of the healthy subjects with MR imaging evidence of Hh developed epilepsy or trouble with cognition. Expand
Voxel-based morphometry reveals gray matter network atrophy in refractory medial temporal lobe epilepsy.
TLDR
Patients with MTLE exhibit a reduction in GMC in regions outside the temporal lobe, specifically in areas that are connected to the hippocampus and parahippocampal region, suggesting an anatomical route for atrophy. Expand
Benign mesial temporal lobe epilepsy
Benign mesial temporal lobe epilepsy (bMTLE), which is defined as at least 24 months of seizure freedom with or without antiepileptic medication, has probably been under-recognized because of aExpand

TLDR
The social rehabilitation was found to be significantly improved by operation at an early age and the more specific and circumscribed the histological abnormality the better the final outcome. Expand
