A COMPARISON OF ACOUSTIC FEATURES IN LVPPA BEFORE AND AFTER TREATMENT PROGRAMMES

The logopenic variant of primary progressive aphasia (lvPPA) is an age-related neurodegenerative syndrome with isolated language impairment. Patients experience symptoms that impair lexical retrieval and impact the phonological loop in the brain. Temporal and prosodic acoustic markers differentiate lvPPA and commonly co-occurring Alzheimer’s Disease and can track the lvPPA-specific phonological loop deficit.  The Western Aphasia Battery (WAB) tests’ and other tasks’ measurements provide targeted acoustic data to analyze with PRAAT software. Transcranial direct current stimulation (tDCS) may be able to enhance language activation of brain region deficits and yield improvement in acoustic dimensions and aphasia severity. The proposed study will compare the acoustic properties of lvPPA patient speech before and after treatment programmes to evaluate therapy effectiveness.
