(Journal article; Peer reviewed, 2021)
      Background: A range of sleep disturbances are commonly experienced by patients with psychiatric disorders, and genome-wide genetic analyses have shown some significant genetic correlations between these traits. Here, we ...
    • Genome-wide analysis reveals genetic overlap between alcohol use behaviours, schizophrenia and bipolar disorder and identifies novel shared risk loci

      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 ...
    • Polygenic overlap and shared genetic loci between loneliness, severe mental disorders, and cardiovascular disease risk factors suggest shared molecular mechanisms 

      Rødevand, Linn; Bahrami, Shahram; Frei, Oleksandr; Lin, Aihua; Gani, Osman; Shadrin, Alexey A.; Smeland, Olav Bjerkehagen; O'Connell, Kevin; Elvsåshagen, Torbjørn; Winterton, Adriano; Quintana, Daniel; Hindley, Guy Frederick Lanyon; Werner, Maren Caroline Frogner; Djurovic, Srdjan; Dale, Anders Martin; Lagerberg, Trine Vik; Steen, Nils Eiel; Andreassen, Ole Andreas (Journal article; Peer reviewed, 2021)
      Clinical and epidemiological evidence suggest that loneliness is associated with severe mental disorders (SMDs) and increases the risk of cardiovascular disease (CVD). However, the mechanisms underlying the relationship ...
