“…Some studies have connected negative symptoms and cognitive impairment in schizophrenia [103, 104, 105]. Maziade et al [106]reported that the three factor model (negative, psychoticism and disorganized factors) was also present in bipolar disorder, suggesting a shared structure for schizophrenia and bipolar disorder which would indicate some continuity in the causes of these disorders.…”

Although cognitive dysfunctions in psychosis have classically been associated with schizophrenia, there is clinical evidence that some bipolar patients show cognitive disturbances either during acute phases or in remission periods. The authors critically review the data on cognitive impairment in bipolar disorder. The main computerized databases (Medline, Psychological Abstracts, Current Contents) have been consulted crossing the terms ‘cognitive deficits’, ‘neuropsychology’, ‘intellectual impairment’, ‘mania’, ‘depression’ and ‘bipolar disorder’. Changes in the fluency of thought and speech, learning and memory impairment, and disturbances in associational patterns and attentional processes are as fundamental to depression and mania as are changes in mood and behavior. Moreover, a significant number of bipolar patients show persistent cognitive deficits during remission from affective symptoms. However, there are several methodological pitfalls in most studies such as unclear remission criteria, diagnostic heterogeneity, small sample sizes, absence of longitudinal assessment, practice effect and poor control of the influence of pharmacological treatment. Most studies point at the presence of diffuse cognitive dysfunction during the acute phases of bipolar illness. Most of these deficits seem to remit during periods of euthymia, but some of them may persist in approximately one third of bipolar patients. Methodological limitations warrant further research in order to clear up the relationship between neuropsychological functioning and clinical, demographic and treatment variables in bipolar disorder.

“…This lack of consistency among the various positive symptoms is hardly sur prising, since clinical experience indicates that patients who have delusions do not nec essarily have disorganized speech, while pa tients who have one negative symptom typi cally have several more, although the particu lar pattern may vary. The fragmenting of posi tive symptoms into several subcategories has led to several recent proposals that the SANS and SAPS be subdivided into three subscales or perhaps even four [25][26][27][28],…”

“…Ideas of reference and persecutory delusions are reported to be associated in factor-analytic and multidimensional scaling studies which use ratings of individual symptoms rather than global symptom ratings (see e.g. Kitamura, Okazaki, Fujinawa, Takayanagi, & Kasahara, 1998;Minas, Stuart, Klimidis et al, 1992).…”

The cognitive neuropsychological understanding of persecutory delusions The cognitive neuropsychological understanding of persecutory delusions AbstractIn considering the contribution of cognitive neuropsychology to the understanding of persecutory delusions, we shall proceed in this chapter as follows: First, we shall consider the contribution of the more conventional clinical neuropsychological approach to the study of delusions. After all, cognitive neuropsychology developed as a hybrid of clinical neuropsychology (the psychological study of brain-injured people) and cognitive psychology (the study of the mental information-processing procedures that people use to perform such activities as speaking and understanding speech, and recognizing objects). Second, we shall outline the cognitive neuropsychological approach with brief reference to its history. Third, we shall describe how this approach has been applied to the study of delusions with reference to our two-deficit cognitive neuropsychological model of monothematic delusions. Finally we shall evaluate the applicability of this model to the explanation of other delusions that are not so obviously neuropsychological; here we shall focus on persecutory delusions.
