    ABSTRACT: The aim of the present study was to assess the emotional and cognitive aspects of social cognition among patients with rolandic epilepsy. A computerized neuropsychological battery was used for cognitive evaluation. Affective and cognitive social cognition were evaluated using two computerized Theory of Mind tasks. Cognitive abilities and social behavior of 15 children, diagnosed with rolandic epilepsy, ages 7 to 13 years were assessed and compared with 15 age- and education-matched healthy controls. Compared with controls, the epileptic patients had lower scores on verbal and visual learning rate parameters and on verbal processing and were significantly impaired on "affective Theory of Mind" tasks but not on "cognitive Theory of Mind" conditions. Our findings raise the possibility that rolandic epilepsy may affect neural networks affecting cognition and mediating social cognition essential for social behavior, thus challenging the benign nature of the condition.

    ABSTRACT: One of the largest clusters of genetic Creutzfeldt-Jakob disease (gCJD) is found among Jews of Libyan origin in Israel and is linked to the E200K mutation in PRNP (gCJDE200K). The aim of this study was to compare the levels of cerebrospinal fluid (CSF) biomarkers, Tau and 14-3-3 proteins, between gCJDE200K patients, sporadic CJD (sCJD) patients and non-CJD controls in Israel between the years 1996-2006. The levels of Tau and 14-3-3 proteins in CSF were measured by ELISA and immunoblotting, respectively. CSF Tau levels were similar in gCJDE200K and sCJD, both were significantly higher than in controls [1,107 ± 470 pg/ml [33/46 (72%)] of the cases >1,000 pg/ml, 1,280 ± 580 pg/ml [25/30 (83.3%)], and 354 ± 338 pg/ml [17/243 (6.9%)], respectively, p < 0.001]. 14-3-3 was detected in CSF of 41/53 (77%) of each gCJDE200K and sCJD patients tested, but only in 70/417 (16.8%) of controls (p < 0.001). An inverse correlation was found between disease duration and Tau levels in both gCJDE200K and sCJD (r = -0.464 and r = -0.284). No difference was found in Tau or 14-3-3 between the various codon 129 genotypes. We conclude that CSF biomarkers, Tau and 14-3-3, may be used in the diagnosis in both patients' populations, presenting a similar sensitivity yet Tau assay having higher specificity.
