PRIMARY PROGRESSIVE APHASIA –CHALLENGES FOR SPEECH AND LANGUAGE THEORY AND PRACTICE

Summary/Abstract: This article examines a new and incompletely studied topic in the field of speech therapy, related to a special type of disorder, primary progressive aphasia. The main purpose of the article is to present a clear definition of this disorder, its characteristics, development, symptoms, therapy, types and etiology. Using modern literature sources and research in the field of aphasiology, the characteristics of the disorder and its variants are derived. A clear definition of the syndrome is given as a progressive degenerative disease characterized by an isolated language disorder. The three main forms of the disorder are presented, namely non-fluent / agrammatic, semantic and logopenic. The diagnostic criteria related to each form of the disorder are considered, as well as the including and excluding diagnostic criteria. The clinical diagnosis is observed in cases with speech and language characteristics that are specific to each variant. It is clear that knowledge of the characteristics of this particular type of disorder is extremely important, because it is the speech and language symptoms of primary progressive aphasia are the first manifestation of the disease and a number of other related neurodegenerative diseases. The symptoms of primary progressive aphasia are complex, and each sum of symptoms can be associated with one of the three variants of the disease and can be important for the future course of the disease. The nuclear characteristics of the primary progressive aphasia and the separate symptoms characteristic of each variant of the disorder are presented. The causes of the disorder are relatively unknown and the relationship of primary progressive aphasia to a specific neuropathological unit has not yet been elucidated. However, the association of the syndrome with other neurodegenerative diseases such as Alzheimer's disease and Frontotemporal lobar dementia has been discussed. Against the background of the clinical picture of primary progressive aphasia, the severity and social significance of the problems related to the probable disability and the need for long-term speech therapy are taken into account. The diagnostic and therapeutic role of the speech therapist and the challenges facing the speech therapy community related to the overall clarification of the phenomenology of this disorder and in particular the need for Bulgarian studies related to this syndrome are revealed.
