Two patients exhibited "echoing approval," a novel speech disorder where responses mirror question syntax or intonation, irrespective of truth. This may indicate bilateral frontosubcortical dysfunction.

Area of Science:

  • Neurology
  • Linguistics
  • Psychiatry

Background:

  • Describes a peculiar speech disorder termed "echoing approval."
  • This disorder involves echoing the syntactical construction or intonation of questions, not repeating sentences.
  • It is distinguished from echolalia and verbal perseverations.

Observation:

  • Patients responded affirmatively to positive questions and negatively to negative questions, regardless of accuracy.
  • Patients agreed or disagreed with unfamiliar medical terminology based solely on syntax or intonation.
  • The disorder was observed in patients with transcortical motor aphasia and frontal lobe signs.

Findings:

  • One patient had a bilateral callosofrontal malignant glioma.
  • The other patient had probable multiple system atrophy with global deterioration and diffuse leukoencephalopathy.

  • Bilateral frontosubcortical dysfunction was prominent in both cases, suggesting involvement of orbitofrontal and frontomesial circuits.

    • Implications:

    • "Echoing approval" may be a manifestation of environment-dependency syndrome.
    • The findings highlight the role of frontosubcortical circuits in speech and cognitive processing.
    • Further research is needed to fully delineate the neural network underlying this speech disorder.
