Summary

Neurogenic stuttering can occur after a left thalamus lesion, impacting propositional speech more than non-propositional speech. This case suggests thalamic stuttering may be a unique clinical condition.

Area of Science:

  • Neuroscience
  • Speech-Language Pathology

Background:

  • Neurogenic stuttering is a speech disorder resulting from neurological damage.
  • Thalamic lesions are not commonly associated with stuttering.

Observation:

  • A 38-year-old male developed severe neurogenic stuttering after an ischemic stroke affecting the left thalamus.
  • Stuttering was pronounced during propositional speech tasks like conversation and naming.
  • Stuttering was minimal during non-propositional speech tasks such as repetition and reading aloud.

Findings:

  • The patient exhibited a clear dissociation between stuttering severity in propositional versus non-propositional speech.
  • The findings indicate a potential link between left thalamus damage and specific stuttering patterns.

Implications:

  • Thalamic stuttering may represent a distinct clinical entity within neurogenic speech disorders.
  • Understanding thalamic contributions to speech fluency can inform diagnosis and treatment strategies.
  • This case highlights the thalamus's role in the complex neural networks supporting speech production.
