INTRODUCTION Neuropsychological aspects of paranoid schizophrenia have still not been examined enough.These disorders are usually not studied separately, but are included in the studies about schizophrenic patients with positive symptoms. Despite the fact that schizophrenia represents a heterogeneous group of mental disorders, usually it is not separated from schizoaffective disorder in neurops...

DSM-III proposes that only persecutory delusions and delusions of jealousy can occur in paranoid disorders, all other types of delusions in the absence of an affective syndrome being indicative of schizophrenia. The scant empirical evidence relevant to this issue suggests that the type of delusion on admission is not predictive of outcome in patients with paranoid psychosis. These findings rais...

Paranoid syndromes in Graves' disease are rare. The true incidence is lacking. Most reports have emanated from developed countries where medical investigations are readily available. No report of such has emanated from Nigeria. We report a 43-year-old female Nigerian with Graves' disease associated with paranoid schizophrenia and review the literature.

Regular ecstasy users show significantly higher levels of self-rated paranoid ideation (SCL-90-R) relative to matched controls [2]. However, regular ecstasy consumers are typically polydrug users and there is evidence that psychopathological symptoms experienced by this group are more strongly associated with the use of other substances, such as cannabis, rather than being solely reflective of ...

The association between BDNF gene functional Val66Met polymorphism rs6265 and the schizophrenia is far from being consistent. In addition to the heterogeneous in schizophrenia per se leading to the inconsistent results, the interaction among multi-genes is probably playing the main role in the pathogenesis of schizophrenia, but not a single gene. Neurotrophic tyrosine kinase receptor 2 (NTRK2) ...

A cognitive model of persecutory delusions is used to predict the occurrence of nonclinical paranoid thoughts in a virtual reality environment. Scorers across the range of paranoia entered a virtual reality scene populated by five computer characters programmed to behave neutrally (N = 30). Many appraisals of the computer characters were positive or neutral. However, there were also persecutory...
