Historically, déjà vu has been linked to seizure activity in temporal lobe epilepsy, and clinical reports suggest that many patients experience the phenomenon as a manifestation of simple partial seizures. We review studies on déjà vu in epilepsy with reference to recent advances in the understanding of déjà vu from a cognitive and neuropsychological standpoint. We propose a decoupled familiarity hypothesis, whereby déjà vu is produced by an erroneous feeling of familiarity which is not in keeping with current cognitive processing. Our hypothesis converges on a parahippocampal dysfunction as the locus of déjà vu experiences. However, several other temporal lobe structures feature in reports of déjà vu in epilepsy. We suggest that some of the inconsistency in the literature derives from a poor classification of the various types of déjà experiences. We propose déjà vu/déjà vécu as one way of understanding déjà experiences more fully. This distinction is based on current models of memory function, where déjà vu is caused by erroneous familiarity and déjà vécu by erroneous recollection. Priorities for future research and clinical issues are discussed.

ObjectivesEver since John Hughlings Jackson first described the so-called ‘dreamy state’ during temporal lobe epilepsy, that is, the sense of an abnormal familiarity (déjà vu) or vivid memory-like hallucinations from the past (experiential hallucinations), these phenomena have been studied and repeatedly linked to mesial temporal lobe structures. However, little is known about the lateralising value of either déjà vu or experiential hallucinations.MethodsWe analysed a sample of 28 patients with intractable focal epilepsy suffering from either déjà vu or experiential hallucinations. All the patients underwent thorough presurgical examination, including MRI, positron emission tomography, single-photon emission CT, EEG and neuropsychological examination.ResultsWhile déjà vu was due to right or left mesial temporal lobe epilepsy, experiential hallucinations were strongly lateralised to the left mesial temporal lobe. Moreover, there was a significant effect for interictal language deficits being more frequent in patients suffering from experiential hallucinations.ConclusionsThese results suggest a lateralising value for experiential hallucinations to the left temporal lobe.

Background: Déjà vu is a common manifestation of temporal lobe seizures. It can be reproduced by electrical stimulation of the hippocampus, amygdala and temporal neocortex with stereotactically implanted electrodes. We report here déjà vu triggered by the stimulation of the insula. Methods: Two patients suffering from intractable temporal lobe epilepsy exhibiting auras of déjà vu underwent invasive EEG studies. One patient had a prior temporal lobectomy with reoccurrence of similar symptoms after surgery. We performed functional connectivity analyses using phase locking value (PLV) to estimate changes in connectivity between different brain regions in the standard EEG frequency bands during stimulation. Results: Stimulation of the insular cortex induced reproducible déjà vu symptoms in both patients. In one patient, PLV analysis showed increased synchronization in the alpha band between insular and temporal regions after an evoked déjà vu compared to a control stimulation. Conclusions: Our results suggest that the insula may in rare occasions generate déjà vu. This implies that insular epileptogenicity cannot be ruled out in patients exhibiting such an aura nor in patients with persisting déjà vu despite an initial amygdalo-hippocampectomy.

Introduction. Deja vu (franc. Déjà vu) is a phenomenon experienced by two thirds of all people. However, this phenomenon can follow aura during the temporal lobe epilepsy. It is believed that it originates from hippocampus, which plays a major role in generating epileptic discharges. Some authors emphasize that in these patients déjà vu phenomenon is not an aura but rather it sometimes refers to the attack itself. Method. In this case report, an eightyear-old girl suffering from repeated crisis of consciousness is described. Case report. The aim of the study was to present the case of an eightyearold girl who underwent three crisis of consciousness, headache behind the forehead as well as the repeated déjà vu phenomenon. The girl was hospitalized, after which medical history was taken and physical examination, as well as other diagnostic tests, were performed. EEG recording revealed an increased electrocortical epileptic activity above the right frontotemporal region. An antiepileptic therapy (Karbapin) leading to attack control was introduced. Conclusion. It is necessary to give temporal lobe epilepsy in children with déjà vu phenomenon serious consideration.
