People with non-fluent/agrammatic primary progressive aphasia often display echolalia

Takeaway

  • Echolalia is common in non-fluent/agrammatic primary progressive aphasia and is characterized by preserved repetition and impaired comprehension.

Why this matters

    Echolalia, the repetition of utterances spoken by another person, is a common feature of transcortical motor or sensory aphasia, but little is known about this condition in neurodegenerative diseases. These important findings reveal new details about echolalia and its underlying neural substrates in primary progressive aphasia which could ultimately lead to better management.
