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...
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 bvFT...
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...
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...
