Automated classification of primary progressive aphasia subtypes from narrative speech transcripts.
In the early stages of neurodegenerative disorders, individuals may exhibit a decline in language abilities that is difficult to quantify with standardized tests. Careful analysis of connected speech can provide valuable information about a patient's language capacities. To date, this type of analysis has been limited by its time-consuming nature. In this study, we present a method for evaluati...
متن کاملAutomated MRI-based classification of primary progressive aphasia variants
Degeneration of language regions in the dominant hemisphere can result in primary progressive aphasia (PPA), a clinical syndrome characterized by progressive deficits in speech and/or language function. Recent studies have identified three variants of PPA: progressive non-fluent aphasia (PNFA), semantic dementia (SD) and logopenic progressive aphasia (LPA). Each variant is associated with chara...
متن کاملAutomatic speech recognition in the diagnosis of primary progressive aphasia
Narrative speech can provide a valuable source of information about an individual’s linguistic abilities across lexical, syntactic, and pragmatic levels. However, analysis of narrative speech is typically done by hand, and is therefore extremely time-consuming. Use of automatic speech recognition (ASR) software could make this type of analysis more efficient and widely available. In this paper,...
متن کاملConnected speech production in three variants of primary progressive aphasia.
Primary progressive aphasia is a clinical syndrome defined by progressive deficits isolated to speech and/or language, and can be classified into non-fluent, semantic and logopenic variants based on motor speech, linguistic and cognitive features. The connected speech of patients with primary progressive aphasia has often been dichotomized simply as 'fluent' or 'non-fluent', however fluency is ...
متن کاملPrimary progressive aphasia: from syndrome to disease.
INTRODUCTION Primary progressive aphasia (PPA) is a clinical syndrome characterised by a progressive decline in language and speech of neurodegenerative origin. Major breakthroughs made in recent years have lent us a better understanding of this syndrome, which may be the first manifestation of any of a number of neurodegenerative diseases. DEVELOPMENT We reviewed the main aspects of PPA epid...
