      Background For many brain disorders, a subset of patients jointly exhibit alterations in cortical brain structure and elevated levels of circulating immune markers. This may be driven in part by shared genetic architecture. ...
    • Genome-wide analyses reveal novel opioid use disorder loci and genetic overlap with schizophrenia, bipolar disorder, and major depression 

      Holen, Børge; Shadrin, Alexey; Icick, Romain; Filiz, Tahir Tekin; Hindley, Guy Frederick Lanyon; Rødevand, Linn; O'Connell, Kevin Sean; Hagen, Espen; Frei, Oleksandr; Bahrami, Shahram; Cheng, Weiqiu; Parker, Nadine; Woldeyohannes, Markos Tesfaye; Jaholkowski, Piotr Pawel; Karadag, Naz; Dale, Anders M; Djurovic, Srdjan; Smeland, Olav Bjerkehagen; Andreassen, Ole (Journal article; Peer reviewed, 2023)
      Opioid use disorder (OUD) and mental disorders are often comorbid, with increased morbidity and mortality. The causes underlying this relationship are poorly understood. Although these conditions are highly heritable, their ...
    • Genome-wide analysis reveals genetic overlap between alcohol use behaviours, schizophrenia and bipolar disorder and identifies novel shared risk loci 

      Wiström, Erik David; O'Connell, Kevin Sean; Karadag, Naz; Bahrami, Shahram; Hindley, Guy Frederick Lanyon; Lin, Aihua; Cheng, Weiqiu; Steen, Nils Eiel; Shadrin, Alexey; Frei, Oleksandr; Djurovic, Srdjan; Dale, Anders M.; Andreassen, Ole A.; Smeland, Olav Bjerkehagen (Journal article; Peer reviewed, 2022)
      Background and aim Schizophrenia (SCZ) and bipolar disorder (BD) have a high comorbidity of alcohol use disorder (AUD), and both comorbid AUD and excessive alcohol consumption (AC) have been linked to greater illness ...
    • Genome-wide Association Analysis of Schizophrenia and Vitamin D Levels Shows Shared Genetic Architecture and Identifies Novel Risk Loci 

      Jaholkowski, Piotr Pawel; Hindley, Guy; Shadrin, Alexey; Tesfaye, Markos; Bahrami, Shahram; Nerhus, Mari; Rahman, Zillur; O'Connell, Kevin Sean; Holen, Børge; Parker, Nadine; Cheng, Weiqiu; Lin, Aihua; Rødevand, Linn; Karadag, Naz; Frei, Oleksandr; Djurovic, Srdjan; Dale, Anders M.; Smeland, Olav Bjerkehagen; Andreassen, Ole (Journal article; Peer reviewed, 2023)
      Low vitamin D (vitD) levels have been consistently reported in schizophrenia (SCZ) suggesting a role in the etiopathology. However, little is known about the role of underlying shared genetic mechanisms. We applied a ...
    • Identification of novel genomic risk loci shared between common epilepsies and psychiatric disorders 

      Karadag, Naz; Shadrin, Alexey; O'Connell, Kevin S; Hindley, Guy Frederick Lanyon; Rahman, Zillur; Parker, Nadine; Bahrami, Shahram; Fominykh, Vera; Cheng, Weiqiu; Holen, Børge; Alvestad, Silje; Taubøll, Erik; Steen, Nils Eiel; Djurovic, Srdjan; Dale, Anders M; Frei, Oleksandr; Andreassen, Ole; Smeland, Olav Bjerkehagen (Journal article; Peer reviewed, 2023)
      Psychiatric disorders and common epilepsies are heritable disorders with a high comorbidity and overlapping symptoms. However, the causative mechanisms underlying this relationship are poorly understood. Here we aimed to ...
    • Shared genetic architecture between schizophrenia and subcortical brain volumes implicates early neurodevelopmental processes and brain development in childhood
