Neuroanatomical features of speech entrainment in aphasia

Takeaway

  • People with non-fluent aphasia caused by stroke without neurological damage in the lateral temporal cortex or temporal white matter exhibit improved fluency after speech entrainment (SE); people with lesion damage in the dorsal stream, but preserved ventral stream, are more likely to respond positively to SE therapy.

Why this matters

    Speech entrainment for non-fluent aphasia caused by stroke has shown improvements in fluency, but research is needed to identify the underlying mechanisms and best candidates for therapy, to improve clinical outcomes.
