Speech and language therapy in primary progressive aphasia: a critical review of current practice.

The challenges in this complex field of practice are described. We highlight the challenge of improving access to speech-language therapy by advocating for increased referral rates. The authors also suggest effective incorporation of innovative technologies in treatment and an enhanced evidence base for the utility of lexical retrieval treatment in improving everyday communication as challenges for the future. Finally, increased provision of PPA-specific education and support for individuals and their families is required.
