She focuses on patients with neurogenic stuttering after strokes.
Many case studies are known.
She talked about prevalance, functioning, MRI scans, and aim to find the lession locations
She had N=37, 17 neurogenic stutterers and 20 controls.
9 areas of the left hemisphere showed differences between control strokes: all important for speech production. She suggest that the location lessions are part of a network that disintegrate and leads to stuttering.
Due to limited coverage, other area might not appear in this study. But her results are consistent with most current understanding of the neurobiological basis.
Interesting avenue, but i am not sure whether you can 100% relate to developmental stuttering. I asked whether there are differences in people who stutter since childhood and those due to a stroke. She said that some patients especially with Parkinson behave differently, but many are similar to "normal" stutterers.
After the talk, I had the opportunity to have an in-depth discussion on her research. An interesting aspect is that most patients are HAPPY to stutter as it is a sign that they improve because the stroke led to a temporal inability to speak.
