“…Other causes of the experience to a pathological degree not discussed here include substance abuse [76], depersonalization or derealisation [77, 78], or migraine [79]. We are aware of cases of debilitating déjà vu which seem to derive from clinical levels of anxiety in cognitively intact people, and this is an area of research worthy of further investigation.…”

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.

“…In two direct comparisons of normal subjects with psychiatric or "neuropsychiatric" patients, déjà vu was less frequent in the normal groups (51 % vs 65 % [21] and 68 % vs 73 % [39]). No significant differences have been found in gender or race, but there is some suggestion that younger age, education and socio-economic status are associated with increased rates of déjà vu [7,21,24,26,33,38,39].…”

The significance of deja vu is widely recognised in the context of temporal lobe epilepsy, and enquiry about deja vu is frequently made in the clinical assessment of patients with possible epilepsy. Deja vu has also been associated with several psychiatric disorders. The historical context of current understanding of deja vu is discussed. The literature reveals deja vu to be a common phenomenon consistent with normality. Several authors have suggested the existence of a "pathological" form of deja vu that differs, qualitatively or quantitatively, from "non-pathological" deja vu. The features of deja vu suggesting neurological or psychiatric pathology are discussed. Several neuroanatomical and psychological models of the deja vu experience are highlighted, implicating the perceptual, mnemonic and affective regions of the lateral temporal cortex, hippocampus and amygdala in the genesis of deja vu. A possible genetic basis for a neurochemical model of deja vu is discussed. Clinical approaches to the patient presenting with possible deja vu are proposed.

There has been an explosion of activity concerning dissociation and dissociative disorders overseas, but little interest is apparent in Australian psychiatric publications. This article aims to critically examine the current conceptualisation of dissociation and its proposed relevance to the understanding of psychopathology, in order to create discussion about these issues in Australian psychiatry. Multiple personality disorder and post-traumatic stress disorder are critically examined.
