Early neurotransmitters changes in prodromal frontotemporal dementia: a GENFI s...
Premi, Enrico; Pengo, Marta; Mattioli, Irene; Cantoni, Valentina; Dukart, Juergen; Gasparotti, Roberto; Buratti, Emanuele; Padovani, AlessandroBackground: Neurotransmitters deficits in Frontotemporal Dementia (FTD) are still poorly understood. Better knowledge of neurotransmitters impairment, especially in prodromal disease stages, might tailor symptomatic treatment approaches. Methods: In the present study, we applied JuSpace toolbox, which allowed for cross-modal correlation of Magnetic Resonance Imaging (MRI)-based measures with nuclear imaging der...
Neurodevelopmental effects of genetic frontotemporal dementia in young adult mu...
Finger, Elizabeth; Malik, Rubina; Bocchetta, Martina; Coleman, Kristy; Graff, Caroline; Borroni, Barbara; Masellis, Mario; Laforce, RobertWhile frontotemporal dementia has been considered a neurodegenerative disease that starts in mid-life or later, it is now clearly established that cortical and subcortical volume loss is observed more than a decade prior to symptom onset and progresses with ageing. To test the hypothesis that genetic mutations causing frontotemporal dementia have neurodevelopmental consequences, we examined the youngest adults ...
Structural brain splitting is a hallmark of Granulin-related frontotemporal dem...
Gazzina, Stefano; Grassi, Mario; Premi, Enrico; Alberici, Antonella; Benussi, Alberto; Archetti, Silvana; Gasparotti, Roberto; Bocchetta, MartinaFrontotemporal dementia associated with granulin (GRN) mutations presents asymmetric brain atrophy. We applied a Minimum Spanning Tree plus an Efficiency Cost Optimization approach to cortical thickness data in order to test whether graph theory measures could identify global or local impairment of connectivity in the presymptomatic phase of pathology, where other techniques failed in demonstrating changes. We ...
Differential early subcortical involvement in genetic FTD within the GENFI cohort
Bocchetta, Martina; Todd, Emily G.; Peakman, Georgia; Cash, David M.; Convery, Rhian S.; Russell, Lucy L.; Thomas, David L.; Eugenio Iglesias, JuanBackground: Studies have previously shown evidence for presymptomatic cortical atrophy in genetic FTD. Whilst initial investigations have also identified early deep grey matter volume loss, little is known about the extent of subcortical involvement, particularly within subregions, and how this differs between genetic groups. Methods: 480 mutation carriers from the Genetic FTD Initiative (GENFI) were included (...

Apathy in presymptomatic genetic frontotemporal dementia predicts cognitive dec...
Malpetti, Maura; Jones, P. Simon; Tsvetanov, Kamen A.; Rittman, Timothy; Swieten, John C.; Borroni, Barbara; Sanchez‐Valle, Raquel; Moreno, FerminIntroduction: Apathy adversely affects prognosis and survival of patients with frontotemporal dementia (FTD). We test whether apathy develops in presymptomatic genetic FTD, and is associated with cognitive decline and brain atrophy. Methods: Presymptomatic carriers of MAPT, GRN or C9orf72 mutations (N = 304), and relatives without mutations (N = 296) underwent clinical assessments and MRI at baseline, and annua...
