White matter disease correlates with lexical retrieval deficits in primary progressive aphasia [PDF]
Frontiers in Neurology, 2013 Objective: To relate fractional anisotropy changes associated with the semantic and logopenic variants of primary progressive aphasia to measures of lexical retrieval.Methods: We collected neuropsychological testing, volumetric MRI, and diffusion ...

Heterogeneity of repetition abilities in logopenic variant primary progressive aphasia
Dementia & Neuropsychologia, 2021 . The differential diagnosis of primary progressive aphasia (PPA) is challenging due to overlapping clinical manifestations of the different variants of the disease.

Logopenic, mixed, or Alzheimer-related aphasia?
Neurology, 2014 This study tested the hypothesis that patients with primary progressive aphasia (PPA) who do not meet the proposed criteria for any of the recognized subtypes would have the atrophy pattern reported in the past for logopenic variant PPA (lvPPA), in turn suggesting that the PPA of likely Alzheimer disease origin is more variable than that captured in ...

Memory and Orientation in the Logopenic and Nonfluent Subtypes of Primary Progressive Aphasia
Journal of Alzheimer's Disease, 2014 Memory and orientation were investigated as predictors of underlying Alzheimer's disease (AD) pathology in patients with logopenic (lv) and non-fluent (na) variants of primary progressive aphasia (PPA). Memory and orientation scores from Addenbrooke's Cognitive Examination were compared between 26 lv-PPA, 29 na-PPA, 59 AD, and 90 controls using ...

Aphasic mild cognitive impairment in prodromal dementia with Lewy bodies
Frontiers in Neurology, 2023 IntroductionThis study aimed to determine the characteristics of aphasic mild cognitive impairment (aphasic MCI), which is characterized by a progressive and relatively prominent language impairment compared with other cognitive impairments, in the ...

Understanding the multidimensional cognitive deficits of logopenic variant primary progressive aphasia. [PDF]
, 2022 The logopenic variant of primary progressive aphasia is characterized by early deficits in language production and phonological short-term memory, attributed to left-lateralized temporoparietal, inferior parietal and posterior temporal neurodegeneration.

The logopenic variant of primary progressive aphasia [PDF]
Current Opinion in Neurology, 2010 The aim is to explore the evolution of the logopenic variant of primary progressive aphasia as a distinct clinical entity and to outline recent advances that have clarified its clinical characteristics, neural underpinnings, and potential genetic and pathological bases.
