Transcranial direct current stimulation (tDCS) combined with speech and language disorder rehabilitation may improve motor speech functions in primary progressive aphasia (PPA). This N-of-1 study showed benefits for articulation and vocalization in a patient with nonfluent variant PPA.
Area of Science:
- Neuroscience
- Neurology
- Speech and Language Pathology
Background:
- Primary progressive aphasia (PPA) is a neurodegenerative condition impacting language.
- Motor speech disorders like dysarthria and apraxia of speech (AOS) are common in nonfluent variant PPA (nfvPPA).
- The efficacy of combining transcranial direct current stimulation (tDCS) with speech and language disorder (SLD) rehabilitation for motor speech deficits in PPA remains unclear.
