Dysfluency (stuttering) in extrapyramidal disease.

W C Koller

    Archives of Neurology
    |March 1, 1983
    PubMed
    Summary
    This summary is machine-generated.

    Adult-onset stuttering can signal underlying neurological conditions like extrapyramidal disease. Early identification of these dysfluencies is crucial for timely diagnosis and management.

    Area of Science:

    • Neurology
    • Speech-Language Pathology

    Background:

    • Acquired stuttering in adults is uncommon, typically linked to trauma or vascular issues.
    • Adult-onset dysfluency is rarely associated with neurodegenerative conditions.

    Observation:

    • A patient presented with adult-onset dysfluency followed by progressive supranuclear palsy symptoms.
    • A review identified five parkinsonian patients exhibiting stuttering-like behavior as an early symptom.

    Findings:

    • Dysfluencies in extrapyramidal disease have a slow onset, characterized by initial syllable repetitions/prolongations in self-formulated speech.
    • These dysfluencies differ from developmental stuttering and acquired stuttering due to vascular or traumatic causes.
    • A positive adaptation effect was noted, with minimal secondary motor symptoms or behavioral responses.

    Implications:

    • Adult-onset stuttering-like dysfluencies warrant consideration of underlying extrapyramidal diseases.
    • Recognizing these speech patterns can aid in early diagnosis of neurodegenerative disorders.
    • Differentiating this dysfluency type is critical for appropriate clinical management.
