      Background One third of people diagnosed with schizophrenia fail to respond adequately to antipsychotic medication, resulting in persisting disabling symptoms, higher rates of hospitalization and higher costs for society. ...

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

      Witoelar, Aree; Rongve, Arvid; Almdahl, Ina Selseth; Ulstein, Ingun; Engvig, Andreas; White, Linda Rosemary; Selbæk, Geir; Stordal, Eystein; Andersen, Fredrik; Brækhus, Anne; Saltvedt, Ingvild; Engedal, Knut; Hughes, Timothy; Bergh, Sverre; Bråthen, Geir; Bogdanovic, Nenad; Bettella, Francesco; Wang, Yunpeng; Athanasiu, Lavinia; Bahrami, Shahram; Le Hellard, Stephanie; Giddaluru, Sudheer; Dale, Anders M; Sando, Sigrid Botne; Steinberg, Stacy; Stefansson, Hreinn; Snaedal, Jon; Desikan, Rahul S; Stefansson, Kari; Aarsland, Dag; Djurovic, Srdjan; Fladby, Tormod; Andreassen, Ole Andreas (Peer reviewed; Journal article, 2018-12-27)
      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) ...

    • Novel loci associated with attention-deficit/hyperactivity disorder are revealed by leveraging polygenic overlap with educational attainment 

      Shadrin, Alexey A.; Smeland, Olav Bjerkehagen; Zayats, Tetyana; Schork, Andrew J; Frei, Oleksandr; Bettella, Francesco; Witoelar, Aree; Li, Wen; Eriksen, Jon Alm; Krull, Florian; Djurovic, Srdjan; Faraone, Stephen V.; Reichborn-Kjennerud, Ted; Thompson, Wesley K; Johansson, Stefan; Haavik, Jan; Dale, Anders; Wang, Yunpeng; Andreassen, Ole Andreas (Peer reviewed; Journal article, 2018-02)
      Objective Attention-deficit/hyperactivity disorder (ADHD) is a common and highly heritable psychiatric condition. By exploiting the reported relationship between ADHD and educational attainment (EA), we aimed to improve ...

    • Polygenic scores for schizophrenia and general cognitive ability: associations with six cognitive domains, premorbid intelligence, and cognitive composite score in individuals with a psychotic disorder and in healthy controls 

      Engen, Magnus Johan; Lyngstad, Siv Hege; Ueland, Torill; Simonsen, Carmen Elisabeth; Vaskinn, Anja; Smeland, Olav Bjerkehagen; Bettella, Francesco; Lagerberg, Trine Vik; Djurovic, Srdjan; Andreassen, Ole Andreas; Melle, Ingrid (Journal article; Peer reviewed, 2020-11)

    • Recently evolved human-specific methylated regions are enriched in schizophrenia signals 

      Banerjee, Niladri; Polushina, Tatiana; Bettella, Francesco; Giddaluru, Sudheer; Steen, Vidar Martin; Andreassen, Ole Andreas; Le Hellard, Stephanie (Peer reviewed; Journal article, 2018)
      Background: One explanation for the persistence of schizophrenia despite the reduced fertility of patients is that it is a by-product of recent human evolution. This hypothesis is supported by evidence suggesting that ...
