Stuttering due to ischemic stroke.

Area of Science:

• Neurology
• Speech-Language Pathology

Background:

• Acquired stuttering is a speech disorder affecting fluency.
• The underlying neurological mechanisms of acquired stuttering remain largely unknown.
• Stuttering can manifest after various forms of brain injury, including cortical and subcortical damage.

Observation:

• Two cases of acquired stuttering following neurological events were observed.
• Both patients presented with stuttering symptoms that were not present prior to their brain injury.
• The onset of stuttering coincided with the neurological damage.

Findings:

• Left parietal lobe infarction was identified as the cause of stuttering in both reported cases.
• This suggests a specific role for the left parietal cortex in speech production and fluency.
• The findings contribute to understanding the neuroanatomy of stuttering.

Implications:

• This research highlights left parietal infarction as a potential cause of acquired stuttering.
• Further investigation into the neural pathways of speech fluency is warranted.
• Clinical recognition of this association may improve diagnosis and management of acquired stuttering.
