- Pineal cysts were identified in 55.6% of a small sample of adults who stutter.
- Pineal cysts were identified in 5.3% of people with no known stuttering.
- This is the first gross structural anomaly associated with stuttering.
- Shared pathogeneses of pineal cysts and stuttering are proposed.
- Researchers are encouraged to reexamine scans of PWS to look for pineal cysts.
