    Background: Recognizing clinical manifestations heralding the development of Alzheimer's disease (AD)-related cognitive impairment could improve the identification of individuals at higher risk of AD who may benefit from ...
  • Centiloid cut-off values for optimal agreement between PET and CSF core AD biomarkers
    Salvadó, Gemma; Molinuevo, José Luis; Brugulat Serrat, Anna, 1986-; Falcón, Carles; Grau-Rivera, Oriol; Suárez-Calvet, Marc; Pavía Segura, Javier; Niñerola-Baizán, Aida; Perissinotti, Andrés; Lomeña, Francisco; Minguillón, Carolina; Fauria, Karine; Zetterberg, Henrik; Blennow, Kaj; Gispert López, Juan Domingo; Alzheimer’s Disease Neuroimaging Initiative (BioMed Central, 2019)
    Background: The Centiloid scale has been developed to standardize measurements of amyloid PET imaging. Reference cut-off values of this continuous measurement enable the consistent operationalization of decision-making for ...
  • Cerebral amyloid-β load is associated with neurodegeneration and gliosis: Mediation by p-tau and interactions with risk factors early in the Alzheimer's continuum
    Salvadó, Gemma; Milà Alomà, Marta; Shekari, Mahnaz; Minguillón, Carolina; Fauria, Karine; Niñerola-Baizán, Aida; Perissinotti, Andrés; Kollmorgen, Gwendlyn; Buckley, Christopher, 1948-; Farrar, Gill; Zetterberg, Henrik; Blennow, Kaj; Suárez-Calvet, Marc; Molinuevo, José Luis; Gispert López, Juan Domingo; ALFA Study (Wiley, 2021)
    Introduction: The association between cerebral amyloid-β accumulation and downstream CSF biomarkers is not fully understood, particularly in asymptomatic stages. Methods: In 318 cognitively unimpaired participants, we ...
  • CSF synaptic biomarkers in the preclinical stage of Alzheimer disease and their association with MRI and PET: a cross-sectional study
    Milà Alomà, Marta; Brinkmalm, Ann; Ashton, Nicholas J.; Kvartsberg, Hlin; Shekari, Mahnaz; Operto, Grégory; Salvadó, Gemma; Falcon, Carles; Domingo Gispert, Juan; Vilor Tejedor, Natàlia, 1988-; Arenaza Urquijo, Eider M.; Grau-Rivera, Oriol; Sala Vila, Aleix; Sanchez-Benavides, Gonzalo; González de Echávarri, José Maria; Minguillón, Carolina; Fauria, Karine; Niñerola-Baizán, Aida; Perissinotti, Andrés; Kollmorgen, Gwendlyn; Suridjan, Ivonne; Zetterberg, Henrik; Molinuevo, José Luis; Blennow, Kaj; Suárez-Calvet, Marc; ALFA Study (Lippincott Williams & Wilkins, 2021)
    Background and objectives: To determine whether CSF synaptic biomarkers are altered in the early preclinical stage of the Alzheimer continuum and associated with Alzheimer disease (AD) risk factors, primary pathology, and ...
  • Differential effects of sleep on brain structure and metabolism at the preclinical stages of AD
    Stankeviciute, Laura; Falcón, Carles; Operto, Grégory; Garcia, Marina; Shekari, Mahnaz; Iranzo, Alex; Niñerola-Baizán, Aida; Perissinotti, Andrés; Minguillón, Carolina; Fauria, Karine; Molinuevo, José Luis; Zetterberg, Henrik; Blennow, Kaj; Suárez-Calvet, Marc; Cacciaglia, Raffaele; Gispert López, Juan Domingo; Grau-Rivera, Oriol; ALFA Study (Wiley, 2023)
    Introduction: Poor sleep quality is associated with cognitive outcomes in Alzheimer's disease (AD). We analyzed the associations between self-reported sleep quality and brain structure and function in cognitively unimpaired ...
  • Quantitative informant‐ and self‐reports of subjective cognitive decline predict amyloid beta PET outcomes in cognitively unimpaired individuals independently of age and APOE ε4
    Sánchez Benavides, Gonzalo; Salvadó, Gemma; Arenaza Urquijo, Eider M.; Grau-Rivera, Oriol; Suárez-Calvet, Marc; Milà Alomà, Marta; González de Echávarri, José Maria; Minguillón, Carolina; Crous-Bou, Marta; Niñerola-Baizán, Aida; Perissinotti, Andrés; Gispert López, Juan Domingo; Molinuevo, José Luis; ALFA Study (Wiley, 2020)
    Introduction: Amyloid beta (Aβ) pathology is an Alzheimer's disease early hallmark. Here we assess the value of longitudinal self- and informant reports of cognitive decline to predict Aβ positron emission tomography (PET) ...
  • Visual assessment of [18F]flutemetamol PET images can detect early amyloid pathology and grade its extent
    Collij, Lyduine E.; Salvadó, Gemma; Shekari, Mahnaz; Lopes Alves, Isadora; Reimand, Juhan; Wink, Alle-Meije; Zwan, Marissa; Niñerola-Baizán, Aida; Perissinotti, Andrés; Scheltens, Philip; Ikonomovic, Milos D.; Smith, Adrian P.L.; Farrar, Gill; Molinuevo, José Luis; Barkhof, Frederik; Buckley, Christopher, 1948-; van Berckel, Bart N. M. (Springer, 2021)
    Purpose: To investigate the sensitivity of visual read (VR) to detect early amyloid pathology and the overall utility of regional VR. Methods: [18F]Flutemetamol PET images of 497 subjects (ALFA+ N = 352; ADC N = 145) were ...
