Summary
A sixty-year-old man developed acquired stuttering following a brainstem infarction. This case suggests the midbrain and upper pons are potential lesion sites for neurogenic stuttering.
Area of Science:
- Neuroscience
- Neurology
- Speech-Language Pathology
Background:
- Acquired stuttering is a rare condition that can occur after neurological damage.
- The specific brain regions responsible for acquired stuttering are not fully understood.
Observation:
- A sixty-year-old male patient presented with acquired stuttering after experiencing a brainstem infarction.
- Imaging revealed infarction in the midbrain and upper pons.
Findings:
- The patient's neurogenic stuttering suggests that the midbrain and upper pons can be critical lesion sites.
- These findings implicate the reticular network and periaqueductal gray matter in the generation of stuttering.
Implications:
- This case highlights the role of brainstem structures in speech fluency.
- Further research into these specific neural pathways may lead to targeted therapies for acquired stuttering.
