Intellectual disability has been diagnosed in 1–3% of the general population. This group is perceived as different partly because of their manner of communicating with those in their environment. The matter of speech and its disorders noted in people with intellectual disability has not yet been completely studied. One significant issue which has rarely been a subject of research is that of changes in communication occurring with age. Among those with intellectual disability, demographic changes noted in the general population may be perceived. A considerable proportion of them reach senior age, and, therefore, undergo both physiological processes of aging, as well as changes of a pathological character. These cause a range of limitations in communication. These changes should be made a significant subject of research.
