What causes stammering?

Stammering occurs in every language and culture throughout the world at 1% of the adult population. People who stammer have the same range of personality and intellectual traits as those who do not, although there are suggestions in the research that they may be more sensitive than is the norm.

Current research is clear that the cause of stammering has a physiological basis in the brain structure. BSA:Research has the details of all the latest research and information. There is no single or definite cure and there is no single best strategy for supporting children as they all have individual needs. Parents cannot cause stammering but there is thought to be a family link in some cases, as where a close adult relative is stammering a young child is more likely to stammer. While the underlying cause of stammering is now understood what is also certain is that stammering speech is also affected by a complex combination of environmental, inherited, linguistic and physical factors that are unique to the individual in their form and effects.

Stammering can emerge at any childhood stage, but most commonly between the ages of two and five when about one in twenty children may stammer. This of course coincides with a period of the rapid development of language skills. At first it affects twice as many boys as girls. Later, as more girls than boys recover, boys who stammer outnumber girls by as much as 5 to 1. It can emerge gradually, but sometimes develops very suddenly. Early Intervention at this age gives the best chance of recovery.

In older children and adults the confirmed condition usually has developed to become more than just a speech difficulty. Feelings and emotions about the stammer and about themselves as people usually become an integral part of the condition and it is essential that support for the management of the stammering is provided. For children small modifications in the speaking and listening environment at home and in school, which make the child feel supported, can lower anxiety levels, and may help with fluency.

Parents do not cause stammering, and with Early Intervention there is an excellent chance of recovery at the pre-school stage with some children recovering as late as 7 or 8 years old.

Parents do not cause stammering

Years ago it was though that parents' behaviour caused the child to stammer. Now research proves that parents do not cause stammering and that this old fashioned view was wrong, although it may still be held by some uninformed people and cause parents considerable distress. However, we do know that parents play a vital role in helping their child by managing the speaking and listening environment in order to reduce the impact of the stammer.
