‘Like going into a chocolate shop, blindfolded’: What do people with primary progressive aphasia want from speech and language therapy?

International journal of language and communication disorders, 2022
Background Primary progressive aphasia (PPA) describes a group of language‐led dementias. PPAs are complex, diverse and difficult to diagnose, and therefore conventional models of aphasia and dementia treatment do not meet their needs.

Speech disorders in primary progressive aphasia (PPA)

Journal of Education, Health and Sport, 2022
Introduction : Primary progressive aphasia (PPA) is a group of neurodegenerative disorders whose main feature is speech and language dysfunction. There are three main forms of PPA - non-fluent variant - agrammatic (nfvPPA), semantic variant (svPPA) and ...

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

Clinical Correlates of Alzheimer's Disease Cerebrospinal Fluid Analytes in Primary Progressive Aphasia

Frontiers in Neurology, 2019
Background: While primary progressive aphasia (PPA) is associated with frontotemporal lobar degeneration (FTLD) pathology due to tau or TDP, clinical-pathological studies also demonstrate many cases have Alzheimer's disease (AD) pathology.

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.

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 ...

Agnosia for accents in primary progressive aphasia. [PDF]

, 2013
As an example of complex auditory signal processing, the analysis of accented speech is potentially vulnerable in the progressive aphasias. However, the brain basis of accent processing and the effects of neurodegenerative disease on this processing are ...

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.

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.
