Do dopamine levels play a role in stuttering?

Posted Jan 20 2011 12:49pm
Holger made me aware that a study on Dopamine Function in Developmental Stuttering has recently been closed. The study
will use positron emission tomography (PET) to examine the role of the chemical messenger dopamine in stuttering. It will measure and compare the number of dopamine receptors and the amount of dopamine released in the brains of stutterers with that of normal volunteers. The results may provide information about how drugs that block dopamine's effect might work to enable fluent speech.
Jerry Maguire is quite interested in this area of research since his involvement in a similar experiment in 1997.

I am just concerned because the starting date is 2001. Did it take ten years? And I never heard about it? Maybe the study never materialized. Would be great if someone could check or replicate Jerry's work.
