Extending the phenotypic spectrum assessed by the CDR plus NACC FTLD in genetic...
Genetic FTD Initiative (GENFI); Samra, Kiran; Peakman, Georgia; MacDougall, Amy M.; Bouzigues, Arabella; Greaves, Caroline V.; Convery, Rhian S.INTRODUCTION: We aimed to expand the range of the frontotemporal dementia (FTD) phenotypes assessed by the Clinical Dementia Rating Dementia Staging Instrument plus National Alzheimer's Coordinating Center Behavior and Language Domains (CDR plus NACC FTLD). METHODS: Neuropsychiatric and motor domains were added to the standard CDR plus NACC FTLD generating a new CDR plus NACC FTLD-NM scale. This was assessed in...
Temporal dynamics predict symptom onset and cognitive decline in familial front...
Whiteside, David J.; Malpetti, Maura; Jones, P Simon; Ghosh, Boyd C. P.; Coyle-Gilchrist, Ian; van Swieten, John C.; Seelaar, Harro; Jiskoot, LizeIntroduction: We tested whether changes in functional networks predict cognitive decline and conversion from the presymptomatic prodrome to symptomatic disease in familial frontotemporal dementia (FTD). Methods: For hypothesis generation, 36 participants with behavioral variant FTD (bvFTD) and 34 controls were recruited from one site. For hypothesis testing, we studied 198 symptomatic FTD mutation carriers, 341...
CSF glial markers are elevated in a subset of patients with genetic frontotempo...
the Genetic FTD Initiative, GENFI; Woollacott, Ione O.C.; Swift, Imogen J.; Sogorb-Esteve, Aitana; Heller, Carolin; Knowles, KathrynBackground: Neuroinflammation has been shown to be an important pathophysiological disease mechanism in frontotemporal dementia (FTD). This includes activation of microglia, a process that can be measured in life through assaying different glia-derived biomarkers in cerebrospinal fluid. However, only a few studies so far have taken place in FTD, and even fewer focusing on the genetic forms of FTD. Methods: We i...

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 ...
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; van der 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 73microtubule-associated protein tau [MAPT]) and 290 controls.Group differences and correlations w...
