To clarify why patients with schizophrenia show déjà vu experiences less frequently, we studied déjà vu experiences in 113 schizophrenic patients in relation to psychopathologies and antipsychotic medication. Déjà vu experiences were observed in 53.1% of the schizophrenic patients. Patients with increased negative symptoms (blunted affect, motor retardation, emotional withdrawal, conceptual disorganization, and mannerisms) had déjà vu experiences less frequently. The other psychopathologies… Expand
Schizophrenia and the paranormal: more psi belief and superstition, and less déjà vu in medicated schizophrenic patients.
These experiences are positively related to paranormal beliefs in healthy adults but not in schizophrenic patients, and Schizophrenic patients have higher scores than healthy adults on the psi and superstitious subscales of the CRPB. Expand
Functional activity changes in memory and emotional systems of healthy subjects with déjà vu
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
Neuroimaging and cognitive changes during déjà vu
The results confirm the role of mesiotemporal structures in the pathogenesis of DV and hypothesize that individual neuroanatomy and disturbances in gamma oscillations or in the dopaminergic system played a role in DBS-elicited DV in a 22-year-old woman treated with deep brain stimulation for hemidystonia.

Recognition Without Identification, Erroneous Familiarity, and Déjà Vu
The need for more experimentation and a more cautious interpretation of research findings is suggested, particularly as many techniques being used to explore déjà vu are in the early stages of development. Expand
The Italian version of the 92-item Prodromal Questionnaire: Concurrent validity with the SIPS and factor analysis in a sample of 258 outpatients aged 11–36years
Optimal cut-offs were confirmed at ≥18 on the positive subscale, but at ≥36 on the total scale was able to identify more SIPS-positive cases, and high internal consistency, acceptable diagnostic accuracy and concurrent validity, and excellent convergent validity. Expand
Déjà Vu in Older Adults


Déjà vu experiences in patients with schizophrenia.
The decreased frequency of the experiences in the patients may suggest déjà vu experiences as nonpathologic phenomena, which is not primarily different in nature from those of the nonclinical subjects. Expand

Higher frequencies of paranormal experiences than those reported previously in the psychiatric literature were attributed to the context of the study and possible psychodynamics of delusions of telepathy were discussed, as were the possible effects of such research on patients' delusions. Expand
Neuropsychological correlates of negative, disorganized and psychotic symptoms in schizophrenia
Data from the Schedules of Negative and Positive Symptoms measured symptom severity in 62 schizophrenics, and a subsequent principal components analysis revealed three symptom dimensions, consistent with hypotheses that these three symptom dimension have distinct neurobehavioral correlates. Expand
Intense and recurrent déjà vu experiences related to amantadine and phenylpropanolamine in a healthy male
It is suggested that déjà vu experiences may be provoked by increased dopamine activity in mesial temporal structures of the brain, which are related to paramnesic symptoms. Expand
Depersonalization phenomena in psychiatric patients.
The present research found that depersonalization occurs more frequently in younger patients who are frequently anxious, who seem to be preoccupied with internal processes, and who have a tendency toward cyclothymia and depression. Expand
Déjà vu experiences and reduplicative paramnesia.
A schizophrenic patient with different forms of experiences of inappropriate familiarity with traumatic experiences as aetiological factors in déjà vu experiences and reduplicative paramnesia is described. Expand

The author proposes the concept of a continuum of positive and negative misidentification symptoms, based on the fact that both déjà vu experiences and depersonalisation occurring in pathological as well as non-pathological conditions are phenomenologically uniform. Expand

The author argues that the phenomenon is the result of faulty and isolated activity of a recognition memory system that consists of the parahippocampal gyrus and its neocortical connections that is responsible for judgments of familiarity. Expand
