    • CSF neurofilament light levels predict hippocampal atrophy in cognitively healthy older adults 

      Idland, Ane-Victoria; Roser, Sala-Llonch; Borza, Tom; Watne, Leiv Otto; Wyller, Torgeir Bruun; Brækhus, Anne; Zetterberg, Henrik; Blennow, Kaj; Walhovd, Kristine B; Fjell, Anders Martin (Journal article; Peer reviewed, 2017)
      Cerebrospinal fluid (CSF) neurofilament light (NFL) is a marker of axonal degeneration. We tested whether CSF NFL levels predict hippocampal atrophy rate in cognitively healthy older adults independently of the established ...
    • Disrupted global metastability and static and dynamic brain connectivity across individuals in the Alzheimer's disease continuum

      As findings on the neuropathological and behavioral components of Alzheimer's disease (AD) continue to accrue, converging evidence suggests that macroscale brain functional disruptions may mediate their association. Recent ...
    • Distinguishing early and late brain aging from the Alzheimer's disease spectrum: Consistent morphological patterns across independent samples 

      Doan, Nhat Trung; Engvig, Andreas; Zaske, Krystal; Persson, Karin; Lund, Martina Jonette; Kaufmann, Tobias; Còrdova Palomera, Aldo; Alnæs, Dag; Moberget, Torgeir; Brækhus, Anne; Barca, Maria Lage; Nordvik, Jan Egil; Engedal, Knut; Agartz, Ingrid; Selbæk, Geir; Andreassen, Ole Andreas; Westlye, Lars Tjelta (Journal article; Peer reviewed, 2017)
      Abstract Alzheimer's disease (AD) is a debilitating age-related neurodegenerative disorder. Accurate identification of individuals at risk is complicated as AD shares cognitive and brain features with aging. We applied ...
