Study Links Stuttering to Less Blood Flow in Brain
Reduced blood flow in a part of the brain that's linked to speech may put people at risk for stuttering, a small study suggests.

There are also signs that the lower the blood flow in regions of the brain tied to speech and language, the more severe the stuttering, the researchers added.

"When other portions of the brain circuit related to speech were also affected according to our blood flow measurements, we saw more severe stuttering in both children and adults," said study first author Dr. Jay Desai. He is a clinical neurologist at Children's Hospital, Los Angeles.

For the study, the investigators used MRI scans to look at the blood flow in the brains of 26 participants with stuttering and 36 participants without the speech disorder....
