      Srinivasan, Saurabh; Bettella, Francesco; Frei, Oleksandr; Hill, W. David; Wang, Yunpeng; Witoelar, Aree; Schork, Andrew J.; Thompson, Wesley Kurt; Davies, Gail; Desikan, Rahul S.; Deary, Ian J.; Melle, Ingrid; Ueland, Torill; Dale, Anders; Djurovic, Srdjan; Smeland, Olav Bjerkehagen; Andreassen, Ole Andreas (Peer reviewed; Journal article, 2018-08-22)
      Higher cognitive functions are regarded as one of the main distinctive traits of humans. Evidence for the cognitive evolution of human beings is mainly based on fossil records of an expanding cranium and an increasing ...

      Dementia with Lewy Bodies (DLB) is a common neurodegenerative disorder with poor prognosis and mainly unknown pathophysiology. Heritability estimates exceed 30% but few genetic risk variants have been identified. Here we ...

    • Genetic Overlap Between Alzheimer’s Disease and Bipolar Disorder Implicates the MARK2 and VAC14 Genes 

      Drange, Ole Kristian; Smeland, Olav Bjerkehagen; Shadrin, Alexey A.; Finseth, Per Ivar; Witoelar, Aree; Frei, Oleksandr; Wang, Yunpeng; Hassani, Sahar; Djurovic, Srdjan; Dale, Anders M; Andreassen, Ole Andreas (Peer reviewed; Journal article, 2019-03-13)
      Background: Alzheimer’s disease (AD) and bipolar disorder (BIP) are complex traits influenced by numerous common genetic variants, most of which remain to be detected. Clinical and epidemiological evidence suggest that AD ...

    • Identification of genetic loci shared between schizophrenia and the Big Five personality traits 

      Smeland, Olav Bjerkehagen; Wang, Yunpeng; Lo, Min-Tzu; Li, Wen; Frei, Oleksandr; Witoelar, Aree; Tesli, Martin Steen; Hinds, David A.; Tung, Joyce Y.; Djurovic, Srdjan; Chen, Chi-Hua; Dale, Anders; Andreassen, Ole Andreas (Peer reviewed; Journal article, 2017-05-22)
      Schizophrenia is associated with differences in personality traits, and recent studies suggest that personality traits and schizophrenia share a genetic basis. Here we aimed to identify specific genetic loci shared between ...

    • Identification of shared genetic variants between schizophrenia and lung cancer 

      Zuber, Verena; Jönsson, Erik Gunnar; Frei, Oleksandr; Witoelar, Aree; Thompson, V K; Schork, Andrew J; Bettella, Francesco; Wang, Yunpeng; Djurovic, Srdjan; Smeland, Olav Bjerkehagen; Dieset, Ingrid; Fanous, Ayman H.; Desikan, Rahul S; Küry, Sébastien; Bezieau, Stephane; Dale, Anders M; Mills, Ian Geoffrey; Andreassen, Ole Andreas (Peer reviewed; Journal article, 2018-01-12)
      Epidemiology studies suggest associations between schizophrenia and cancer. However, the underlying genetic mechanisms are not well understood, and difficult to identify from epidemiological data. We investigated if there ...

    • Meta-analysis of Alzheimer’s disease on 9,751 samples from Norway and IGAP study identifies four risk loci
