Acquired stuttering after a second stroke in a two-year-old

Area of Science:

• Neuroscience
• Developmental Pediatrics
• Speech-Language Pathology

Background:

• Understanding the neurobiological underpinnings of developmental stuttering.
• Investigating the role of hemispheric dominance and interhemispheric connectivity in speech fluency.

Observation:

• A left-handed girl experienced transient stuttering following a left-hemisphere stroke.
• The stroke occurred at one year of age and was associated with new white matter infarctions.

Findings:

• The case suggests a potential link between anomalous brain dominance and atypical interhemispheric connectivity in developmental stuttering.
• Transient stuttering in this case may be associated with neurological changes.

Implications:

• This case highlights the importance of considering neurological factors in the etiology of developmental stuttering.
• Further research into brain connectivity may offer new insights into stuttering.
