    • Combinatory microRNA serum signatures as classifiers of Parkinson's disease 

      Patil, Ketan S.; Basak, Indranil; Dalen, Ingvild; Hoedt, Esthelle; Lange, Johannes; Lunde, Kristin Aaser; Liu, Ying; Tysnes, Ole-Bjørn; Forsgren, Lars; Aarsland, Dag; Neubert, Thomas A.; Larsen, Jan Petter; Alves, Guido Werner; Møller, Simon Geir (Journal article; Peer reviewed, 2019-04)
      As current clinical diagnostic protocols for Parkinson's disease (PD) may be prone to inaccuracies there is a need to identify and validate molecular biomarkers, such as circulating microRNAs, which will complement current ...
    • Lack of Association Between GBA Mutations and Motor Complications in European and American Parkinson's Disease Cohorts 

      Grødem, Jodi Maple; Paul, Kimberly C.; Dalen, Ingvild; Ngo, Kathie J.; Wong, Darice; Macleod, Angus D.; Counsell, Carl E.; Bäckström, David; Forsgren, Lars; Tysnes, Ole-Bjørn; Kusters, Cynthia D.J.; Fogel, Brent L.; Bronstein, Jeff M.; Ritz, Beate; Alves, Guido Werner (Peer reviewed; Journal article, 2021)
      Background: Motor complications are a consequence of the chronic dopaminergic treatment of Parkinson’s disease (PD) and include levodopa-induced dyskinesia (LIDs) and motor fluctuations (MF). Currently, evidence is on ...
