Altered plasma protein profiles in genetic FTD – a GENFI study
Ullgren, Abbe; Öijerstedt, Linn; Olofsson, Jennie; Bergström, Sofia; Remnestål, Julia; van Swieten, John C.; Jiskoot, Lize C.; Seelaar, HarroBackground: Plasma biomarkers reflecting the pathology of frontotemporal dementia would add significant value to clinical practice, to the design and implementation of treatment trials as well as our understanding of disease mechanisms. The aim of this study was to explore the levels of multiple plasma proteins in individuals from families with genetic frontotemporal dementia. Methods: Blood samples from 693 pa...
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 ...
Caffeine intake exerts dual genome-wide effects on hippocampal metabolism and l...
Paiva, Isabel; Cellai, Lucrezia; Meriaux, Céline; Poncelet, Lauranne; Nebie, Ouada; Saliou, Jean-Michel; Lacoste, Anne-Sophie; Papegaey, AnthonyCaffeine is the most consumed psychoactive substance worldwide. Strikingly, molecular pathways engaged by its regular consumption remain unclear. We herein addressed the mechanisms associated with habitual (chronic) caffeine consumption in the mouse hippocampus using untargeted orthogonal-omics techniques. Our results revealed that chronic caffeine exerts concerted pleiotropic effects in the hippocampus, at the...

Language impairment in the genetic forms of behavioural variant frontotemporal ...
Samra, Kiran; MacDougall, Amy M.; Bouzigues, Arabella; Bocchetta, Martina; Cash, David M.; Greaves, Caroline V.; Convery, Rhian S.; van Swieten, John C.Background: Behavioural variant fronto-temporal dementia (bvFTD) is characterised by a progressive change in personality in association with atrophy of the frontal and temporal lobes. Whilst language impairment has been described in people with bvFTD, little is currently known about the extent or type of linguistic difficulties that occur, particularly in the genetic forms. Methods: Participants with genetic bv...
Examining empathy deficits across familial forms of frontotemporal dementia wit...
Foster, Phoebe H.; Russell, Lucy L.; Peakman, Georgia; Convery, Rhian S.; Bouzigues, Arabella; Greaves, Caroline V.; Bocchetta, Martina; Cash, David M.Background: Reduced empathy is a common symptom in frontotemporal dementia (FTD). Although empathy deficits have been extensively researched in sporadic cases, few studies have explored the differences in familial forms of FTD. Methods: Empathy was examined using a modified version of the Interpersonal Reactivity Index (mIRI) in 676 participants from the Genetic FTD Initiative: 216 mutation-negative controls, 1...
Anomia is present pre-symptomatically in frontotemporal dementia due to MAPT mu...
Bouzigues, Arabella; Russell, Lucy L.; Peakman, Georgia; Bocchetta, Martina; Greaves, Caroline V.; Convery, Rhian S.; Todd, Emily; Rowe, James B.Introduction: A third of frontotemporal dementia (FTD) is caused by an autosomal-dominant genetic mutation in one of three genes: microtubule-associated protein tau (MAPT), chromosome 9 open reading frame 72 (C9orf72) and progranulin (GRN). Prior studies of prodromal FTD have identified impaired executive function and social cognition early in the disease but few have studied naming in detail. Methods: We inves...
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 (...
Impairment of episodic memory in genetic frontotemporal dementia : a GENFI study
Poos, Jackie M.; Russell, Lucy L.; Peakman, Georgia; Bocchetta, Martina; Greaves, Caroline V.; Jiskoot, Lize C.; Ende, Emma L.; Seelaar, HarroIntroduction: We aimed to assess episodic memory in genetic frontotemporal dementia (FTD) with the Free and Cued Selective Reminding Test (FCSRT). Methods: The FCSRT was administered in 417 presymptomatic and symptomatic mutation carriers (181 chromosome 9 open reading frame 72 [C9orf72], 163 progranulin [GRN], and 73 microtubule-associated protein tau [MAPT]) and 290 controls. Group differences and correlation...
