title: Dreamy states and psychoses in temporal lobe epilepsy: mediating role of affect.
abstract: Among 104 patients with temporal lobe epilepsy treated in our clinic between 1992-1995, thirteen patients with repeated dreamy states were evaluated for affective manifestations of dreamy states and their relationship with psychotic states. The types of dreamy states were classified as déjà vu, jamais vu and reminiscence. The affective experiences during dreamy states were evaluated as positive, negative or neutral. As a result, seven patients had déjà vu and/or reminiscence: seizure manifestations in four of these patients were affectively evaluated as positive (familiar and/or pleasurable), and three as neutral. Six cases had experience of jamais vu: five of them were affectively evaluated as negative (mostly fear), and one as neutral. Psychiatrically, only four patients with jamias vu accompanied by feelings of fear had mental disorders: a chronic paranoid-hallucinatory state in two cases, a chronic paranoid state in one case, and obsessive-compulsive symptoms in one case. Other patients who had positive or neutral affect did not demonstrate psychiatric disturbances. Thus, most patients with jamais vu were accompanied by negative affect of fear, and those patients with jamais vu tended to show more psychotic symptoms than those with reminiscence or déjà vu, which were associated with positive or neutral affects. Based on these results, we discuss the possibility that repeated negative feelings associated with jamais vu are one of the causes for developing epileptic psychoses.
