Jargonaphasia in logopenic variant primary progressive aphasia
Journal of the Neurological Sciences, 2023Logopenic variant primary progressive aphasia (lvPPA), which is most commonly an early onset variant of Alzheimer's disease (AD), is a progressive impairment in word retrieval and language expression. Clinicians often misdiagnose these patients when they present with severely unintelligible speech consistent with jargonaphasia.We reviewed all patients ...

Towards a Clearer Definition of Logopenic Progressive Aphasia
Current Neurology and Neuroscience Reports, 2013Logopenic progressive aphasia is the most recently described clinical variant of primary progressive aphasia (PPA), defined by impairment of lexical retrieval and sentence repetition. Unlike other PPA variants, the logopenic variant of PPA (lv-PPA) is commonly associated with Alzheimer's disease (AD), a fact that is relevant to the selection of ...

Progressive logopenic/phonological aphasia: Erosion of the language network
NeuroImage, 2010 The primary progressive aphasias (PPA) are paradigmatic disorders of language network breakdown associated with focal degeneration of the left cerebral hemisphere. Here we addressed brain correlates of PPA in a detailed neuroanatomical analysis of the third canonical syndrome of PPA, logopenic/phonological aphasia (LPA), in relation to the more widely ...

Ideomotor apraxia in agrammatic and logopenic variants of primary progressive aphasia [PDF]
Journal of Neurology, 2013 There are few studies examining praxis in subjects with primary progressive aphasia. The aim of this study was to examine the pattern and severity of ideomotor apraxia in subjects with logopenic and agrammatic variants of primary progressive aphasia and to determine if the presence of ideomotor apraxia correlated with specific neuroanatomical ...

Spatial neglect in a patient with logopenic progressive aphasia
Neurocase, 2015Spatial neglect and extinction are induced by posterior superior temporal and inferior parietal dysfunction. In patients with logopenic progressive aphasia (LPA) these structures are often degenerated, but there are no reports of these disorders being associated.

Cognitive decline in logopenic aphasia
Neurology, 2013To track cognitive and language changes over time in patients with logopenic (lv-PPA) and semantic (sv-PPA) variants of primary progressive aphasia (PPA).Thirteen consecutive patients with lv-PPA and 11 patients with sv-PPA underwent yearly evaluation for a mean of 3 years.

Logopenic Primary Progressive Aphasia
2017Logopenic primary progressive aphasia is an atypical variant of Alzheimer’s disease characterized by decreased rate of spontaneous language production. PET/MR imaging demonstrates cortical atrophy and corresponding hypometabolism, typically most severe in the left lateral temporoparietal region.

Crossed aphasia is a rare phenomenon, with a prevalence of 1% to 2% among all right-handed patients. Two crossed aphasic patients with a nonfluent variant of primary progressive aphasia (PPA) have been reported previously. This report aims to document for the first time the occurrence of crossed logopenic progressive aphasia in a dextral patient.A 57 ...

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
