Non-verbal episodic memory deficits in primary progressive aphasias are highly predictive of underlying amyloid pathology [PDF]

, 2016
Diagnostic distinction of primary progressive aphasias (PPA) remains challenging, in particular for the logopenic (lvPPA) and nonfluent/agrammatic (naPPA) variants.

Comprehension of acoustically degraded speech in Alzheimer’s disease and primary progressive aphasia

medRxiv, 2022
Successful communication in daily life frequently depends on accurate decoding of speech signals that are acoustically degraded by challenging listening conditions. This process presents the brain with a demanding computational task that is vulnerable to

Logopenic and nonfluent variants of primary progressive aphasia are differentiated by acoustic measures of speech production [PDF]

, 2014
Differentiation of logopenic (lvPPA) and nonfluent/agrammatic (nfvPPA) variants of Primary Progressive Aphasia is important yet remains challenging since it hinges on expert based evaluation of speech and language production.

Cortical microstructure in primary progressive aphasia: a multicenter study

Alzheimer's Research & Therapy, 2022
Cortical mean diffusivity is a novel imaging metric sensitive to early changes in neurodegenerative syndromes. Higher cortical mean diffusivity values reflect microstructural disorganization and have been proposed as a sensitive biomarker that might ...

Non-primary progressive language impairment in neurodegenerative conditions: protocol for a scoping review

Systematic Reviews, 2021
Background Progressive language difficulties arise in many neurodegenerative conditions, causing significant impact upon patients and families. This occurs most obviously in primary progressive aphasia (PPA) but can also occur within other forms of ...

Dysgraphia Phenotypes in Native Chinese Speakers With Primary Progressive Aphasia

Neurology, 2022
Background and Objectives Most primary progressive aphasia (PPA) literature is based on English language users. Linguistic features that vary from English, such as logographic writing systems, are underinvestigated.

Difficulties of clinical diagnosis in primary progressive aphasia. Clinical observation

Анналы клинической и экспериментальной неврологии, 2019
Primary progressive aphasia is a syndrome characterized by progressive speech dysfunction. There are three types of this condition. The first agrammatic type of primary progressive aphasia is typical for frontotemporal dementia and characterized by ...

Transcranial Direct Current Stimulation Paired With Verb Network Strengthening Treatment Improves Verb Naming in Primary Progressive Aphasia: A Case Series.

American Journal of Speech-Language Pathology, 2022
PURPOSE There are few evidence-based treatments for language deficits in primary progressive aphasia (PPA). PPA treatments are often adopted from the poststroke aphasia literature.

Primary progressive aphasia and motor neuron disease: A review

Frontiers in Aging Neuroscience, 2022
Background This study aims at reviewing, within the framework of motor neuron disease-frontotemporal degeneration (MND-FTD)-spectrum disorders, evidence on the co-occurrence between primary progressive aphasia (PPA) and MND in order to profile such a ...
