As per a recent study, reduced blood flow in brain linked to speech production can cause stuttering in people.
Researchers at Children’s Hospital Los Angeles in the US demonstrated evidence of a common underlying lifelong vulnerability in both children and adults who stutter.
They discovered that regional cerebral blood flow is reduced in the Broca’s area – the region in the frontal lobe of the brain linked to speech production – in persons who stutter.
More severe stuttering is associated with even greater reductions in blood flow to this region.
This finding suggests that a common pathophysiology throughout the neural “language” loop that connects the frontal and posterior temporal lobe likely contributes to stuttering severity.
