    • Association Between Amygdala Volume and Trajectories of Neuropsychiatric Symptoms in Alzheimer’s Disease and Dementia With Lewy Bodies 

      Jaramillo-Jiménez, Alberto; Melvær, Giil Lasse; Tovar-Rios, Diego Alejandro; Borda, Miguel Germán; Ferreira, Daniel; Brønnick, Kolbjørn Kallesten; Oppedal, Ketil; Aarsland, Dag (Peer reviewed; Journal article, 2021-07)
      Introduction: The amygdala is implicated in psychiatric illness. Even as the amygdala undergoes significant atrophy in mild dementia, amygdala volume is underexplored as a risk factor for neuropsychiatric symptoms ...

    • The combined effect of amyloid-β and tau biomarkers on brain atrophy in dementia with Lewy bodies 

      Abdelnour, Carla; Ferreira, Daniel; Oppedal, Ketil; Cavallin, Lena; Bousiges, Olivier; Wahlund, Lars Olof; Hort, Jakub; Nedelska, Zuzana; Padovani, Alessandro; Pilotto, Andrea; Bonanni, Laura; Kramberger, Milica Gregoric; Boada, Mercè; Westman, Eric; Pagonabarraga, Javier; Kulisevsky, Jaime; Blanc, Frédéric; Aarsland, Dag (Peer reviewed; Journal article, 2020-07)
      Background Alzheimer’s disease (AD)-related pathology is frequently found in patients with dementia with Lewy bodies (DLB). However, it is unknown how amyloid-β and tau-related pathologies influence neurodegeneration in ...
