Many Faces of Déjà Vu: a Narrative Review.

French expression standing for the phrase "already seen" is a déjà vu. It is thought that as much as 97% of the population have experienced déjà vu at least once in their lifetime and 67% experience it regularly. The explanations of this phenomenon in novels and poems include reincarnation, dreams, organic factors, and unconscious memories. In this narrative review connection between déjà vu and various other conditions has been mentioned: false memories, temporal lobe epilepsy and other neurological conditions. In psychiatric patients déjà vu phenomenon is more often seen in patients with anxiety and people with derealisation/ depersonalization. It seems that temporal region is the origin of déjà vu phenomena in both healthy individuals and in individuals with neurological and psychiatric conditions, but the exact mechanism of this phenomenon is however still unknown. More attention should also be given to déjà vu from philosophical and religious perspectives as well. Déjà vu is still an enigma which could only be revealed with multidisciplinary approach through cooperation between neurologists, brain scientists, psychiatrists and experimental psychologists.

[Reversible posterior leukoencephalopathy or brain tumor--case report]. / Reverzibilna posteriorna leukoencefalopatija ili tumor mozga--prikaz bolesnice.

Reversible posterior leukoencephalopathy (RPLE) syndrome is clinically associated with headache, altered consciousness, seizures and visual symptoms. On brain magnetic resonance imaging (MRI) there is edema predominantly affecting white matter of the parietooccipital brain regions. Initially, this syndrome was believed to be secondary to hypertension, renal disease, or immunosuppressive therapy. However, it has recently been identified in a wide variety of conditions, including eclampsia, hemolytic-uremic syndrome, connective tissue diseases, malignancies, etc. Authors describe a case of a 72-year-old woman with a history of arterial hypertension, who suddenly developed headache, confusion, left homonymous hemianopsia, and left hemiparesis, associated with high blood pressure. Brain MRI revealed extensive white matter lesion in the right parietal and occipital lobe, splenium corpus callosum and left occipital lobe, suggestive of expansive process. However, after extensive diagnostic work-up, diagnosis of reversible posterior leukoencephalopathy was established, connected with arterial hypertension. At the moment the patient is without neurological symptoms, follow-up brain MRI revealed resolution of white matter lesion.
