Dementia trajectory for patients with logopenic variant primary progressive aphasia
Neurological Sciences, 2019The timing of progression of logopenic variant primary progressive aphasia (lvPPA) to severe dementia has not been elucidated. To address this shortcoming, 10 patients with lvPPA were continuously followed.Patients were assessed with the annual rate of change in the Clinical Dementia Rating (CDR) sum of boxes and period from lvPPA onset to the onset of

[Specificities of the logopenic variant of primary progressive aphasia].
Revue neurologique, 2015The logopenic variant of primary progressive aphasia is a syndrome with neuropsychological and linguistic specificities, including phonological loop impairment for which diagnosis is currently mainly based on the exclusion of the two other variants, semantic and nonfluent/agrammatic primary progressive aphasia. The syndrome may be underdiagnosed due (1)
