What causes stuttering?

There are no accepted biological or psychological reasons for why people stutter. Despite the challenges involved with stuttering, it isn’t associated with mental disorders, personality disorders, or intelligence disorders. The majority of stutterers have normal intelligence.

Most experts believe that stuttering comes from a combination of biological and environmental factors. Stuttering does run in families, which indicates some neurological and genetic causes. If one identical twin stutters, there’s a greater chance that the other twin will become a stutterer.

Peter Wolson, a psychoanalyst, considers psychological and social reasons for stuttering. He thinks some cases of stuttering arise from internal conflicts due to family influences.

Both of these theories are compelling. I still think we’ll need years of research before cracking down on the exact mechanisms that lead to stuttering. In the meantime, if you have a child who stutters, bring him or her to visit a speech-language pathologist for counseling before the stuttering too strongly affects his or her social well-being.

Stuttering can be caused, in rare cases, by psychological rather than physiological challenges. However, stuttering is more commonly attributed to head trauma, developmental challenges, or genetic predisposition. Scientists believe that three genes are particularly linked to persistent stuttering. Stuttering is most commonly caused in children as they are learning to speak. When it does not go away on its own, it can often be treated with speech therapy.
