      Migraine is three times more prevalent in people with bipolar disorder or depression. The relationship between schizophrenia and migraine is less certain although glutamatergic and serotonergic neurotransmission are ...
    • 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 ...
    • Meta-analysis of Alzheimer’s disease on 9,751 samples from Norway and IGAP study identifies four risk loci

      A large fraction of genetic risk factors for Alzheimer’s Disease (AD) is still not identified, limiting the understanding of AD pathology and study of therapeutic targets. We conducted a genome-wide association study (GWAS) ...
    • 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 ...
    • The shared genetic basis of mood instability and psychiatric disorders: A cross-trait genome-wide association analysis 

      Hindley, Guy Frederick Lanyon; O'Connell, Kevin Sean; Rahman, Zillur; Frei, Oleksandr; Bahrami, Shahram; Shadrin, Alexey; Høegh, Margrethe Collier; Cheng, Weiqiu; Karadag, Naz; Lin, Aihua; Rødevand, Linn; Fan, Chun C.; Djurovic, Srdjan; Lagerberg, Trine Vik; Dale, Anders; Smeland, Olav Bjerkehagen; Andreassen, Ole (Journal article; Peer reviewed, 2022)
      Recent genome-wide association studies of mood instability (MOOD) have found significant positive genetic correlation with major depression (DEP) and weak correlations with other psychiatric disorders. We investigated the ...
