Abstract

Objective: There are only few studies that focused on the personality risk factors for bipolar II disorder. The aim of this study was to find personality risk factors with reference to family history, social circumstances and comorbid symptoms for bipolar II disorder. Method: The most important methodological limitation of studies that investigate risk factors for mood disorders is their limited longitudinal design. In order to address this issue, the data of the Zurich study was used. The Zurich cohort study - a longitudinal study - is composed of a cohort of 4,547 subjects (m=2201; f=2346) representative of the canton Zurich in Switzerland. Results: Frequent ups and downs of mood and family history of neutrasthenia und mania are the most important predictors for experiencing a bipolar II disorder. Conclusion: The probability of developing a bipolar II disorder can be estimated by genetic and personality variable or early prodromal symptoms. There is some evidence suggesting that there are unspecific genetic factors that contribute to the risk for a bipolar II disorder.

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
