This review summarizes clinical and imaging features associated with primary progressive aphasia (PPA). We investigate the hypothesis that these patients can be divided into subgroups of progressive non-fluent aphasia (PNFA) and semantic dementia (SD), based on their linguistic profiles and related imaging studies, and examine whether each of these major subgroups can be further subdivided.

متن کاملSpelling Intervention in Post-Stroke Aphasia and Primary Progressive Aphasia
Spelling - a core language skill - is commonly affected in neurological diseases such as stroke and Primary Progressive Aphasia (PPA). We present two case studies of the same spelling therapy (learning of phoneme-to-grapheme correspondences with help from key words) in two participants: one who had a stroke and one with PPA (logopenic variant). Our study highlights similarities and differences ...

Here we describe two patients with primary progressive aphasia (PPA) who produced neologistic jargon either in speech or writing. We suggest that involvement of the posterior superior temporal-...
