Importance Genetic factors contribute to risk for bipolar disorder (BP), but its pathogenesis remains poorly understood. A focus on measuring multisystem quantitative traits that may be components of BP psychopathology may enable genetic dissection of this complex disorder, and investigation of extended pedigrees from genetically isolated populations may facilitate the detection of specific genetic variants that affect BP as well as its component phenotypes. Objective To identify quantitative neurocognitive, temperament-related, and neuroanatomical phenotypes that appear heritable and associated with severe BP (bipolar I disorder [BP-I]) and therefore suitable for genetic linkage and association studies aimed at identifying variants contributing to BP-I risk.

Abstract: Objective: Cretzfeldt-Jacob Disease (CJD) is a rapidly progressive spongiform disease of the central nervous system. Psychiatric symptoms, though considered rare, can be the presenting symptoms of CJD and impose diagnosis difficulties. We reviewed prospectively our database to identify the frequency of psychiatric symptoms as identifying symptoms among our community.Metods: We included all patients in Sheba Medical Center who were diagnosed with CJD between the years 2006 – 2012.

Importance Neurochemical studies in human aggression point to a modulatory role for a variety of central neurotransmitters. Some of these neurotransmitters play an inhibitory role, while others play a facilitatory role modulating aggression.
