Right versus left hemisphere-predominant logopenic progressive aphasia: differing characteristics


  • Patients with right hemisphere-predominant logopenic progressive aphasia (rLPA) had milder aphasia, with fewer phonologic errors and fewer errors in writing irregular words compared with typical logopenic progressive aphasia (LPA), but also experienced shorter survival from symptom onset.

Why this matters

    Cases of predominantly rLPA are less common than LPA but have been reported; however, there are gaps in our understanding. The present study exposes key differences between rLPA and LPA that may impact disease prognosis.
