An “Elevator Speech” for Stuttering

With the discovery and recent verification, over the past 10-12 years, of neurological correlates for childhood stuttering in 1) white matter fiber tracts from premotor planning and linguistic areas of the left hemisphere (Chang 2009, etc.) and 2) genetic lysosomal disorders in neurons (waste processing systems) (Drayna, NIH), it is possible to predict emotional reactions associated with delays or errors in required inputs for speech to the “go” and “no-go” systems at the basal ganglia.

Thus, the following prospective “elevator speech” is possible for the long-sought cause of stuttering:

“Stuttering behavior is caused by emotional reactions to timing delays and errors in the neurological speech system, which become fear-conditioned over time.”
