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...
Longitudinal cerebral perfusion in presymptomatic genetic frontotemporal dement...
The Genetic Frontotemporal Dementia Initiative (GENFI); Pasternak, Maurice; Mirza, Saira S.; Luciw, Nicholas; Mutsaerts, Henri J. M. M.; Petr, JanINTRODUCTION: Effective longitudinal biomarkers that track disease progression are needed to characterize the presymptomatic phase of genetic frontotemporal dementia (FTD). We investigate the utility of cerebral perfusion as one such biomarker in presymptomatic FTD mutation carriers. METHODS: We investigated longitudinal profiles of cerebral perfusion using arterial spin labeling magnetic resonance imaging in 4...
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...
The Benson Complex Figure Test detects deficits in visuoconstruction and visual...
Jiskoot, Lize C.; Russell, Lucy L.; Peakman, Georgia; Convery, Rhian S.; Greaves, Caroline V.; Bocchetta, Martina; Poos, Jackie M.; Seelaar, HarroSensitive cognitive markers are still needed for frontotemporal dementia (FTD). The Benson Complex Figure Test (BCFT) is an interesting candidate test, as it assesses visuospatial, visual memory, and executive abilities, allowing the detection of multiple mechanisms of cognitive impairment. To investigate differences in BCFT Copy, Recall and Recognition in presymptomatic and symptomatic FTD mutation carriers, a...
Motor symptoms in genetic frontotemporal dementia: developing a new module for ...
Samra, Kiran; MacDougall, Amy M.; Peakman, Georgia; Bouzigues, Arabella; Bocchetta, Martina; Cash, David M.; Greaves, Caroline V.; Convery, Rhian S.Objective To investigate the optimal method of adding motor features to a clinical rating scale for frontotemporal dementia (FTD). Methods Eight hundred and thirty-two participants from the international multicentre Genetic FTD Initiative (GENFI) study were recruited: 522 mutation carriers (with C9orf72, GRN and MAPT mutations) and 310 mutation-negative controls. A standardised clinical questionnaire was used t...
Neuropsychiatric symptoms in genetic frontotemporal dementia: developing a new ...
Samra, Kiran; Macdougall, Amy; Peakman, Georgia; Bouzigues, Arabella; Bocchetta, Martina; Cash, David M.; Greaves, Caroline V.; Convery, Rhian S.Background Current clinical rating scales in frontotemporal dementia (FTD) often do not incorporate neuropsychiatric features and may therefore inadequately measure disease stage. Methods 832 participants from the Genetic FTD Initiative (GENFI) were recruited: 522 mutation carriers and 310 mutation-negative controls. The standardised GENFI clinical questionnaire assessed the frequency and severity of 14 neurops...
Genetic forms of primary progressive aphasia within the GENetic Frontotemporal ...
Samra, Kiran; MacDougall, Amy M.; Bouzigues, Arabella; Bocchetta, Martina; Cash, David M.; Greaves, Caroline V.; Convery, Rhian S.; Hardy, ChrisPrimary progressive aphasia is most commonly a sporadic disorder, but in some cases, it can be genetic. This study aimed to understand the clinical, cognitive and imaging phenotype of the genetic forms of primary progressive aphasia in comparison to the canonical nonfluent, semantic and logopenic subtypes seen in sporadic disease. Participants with genetic primary progressive aphasia were recruited from the int...
Prodromal language impairment in genetic frontotemporal dementia within the GEN...
Samra, Kiran; MacDougall, Amy M.; Bouzigues, Arabella; Bocchetta, Martina; Cash, David M.; Greaves, Caroline V.; Convery, Rhian S.; van Swieten, John C.Objective: To identify whether language impairment exists presymptomatically in genetic frontotemporal dementia (FTD), and if so, the key differences between the main genetic mutation groups. Methods: 682 participants from the international multicentre Genetic FTD Initiative (GENFI) study were recruited: 290 asymptomatic and 82 prodromal mutation carriers (with C9orf72, GRN, and MAPT mutations) as well as 310 m...
Language impairment in the genetic forms of behavioural variant frontotemporal ...
On Behalf of the Genetic FTD Initiative (GENFI); Samra, Kiran; MacDougall, Amy M.; Bouzigues, Arabella; Bocchetta, Martina; Cash, David M.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...
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...
