Expressive language may remain intact over a long period, thus acting as a measure of overall ability. Studies have extensively examined adults with Down syndrome on their communication and language.
Studies based on downs syndrome are increasing rapidly. Most of these studies seek to establish the connection among ageing, language and correlated skills in adults. According to Iacono, Torr, &Wong’s inferences, the measures of relationship between language and ageing fail to investigate linguistic domains but rather sensitivity to change. It is evident that expressive language tends to decline with age among adults with downs syndrome compared to receptive language. Studies show that, receptive vocabulary is stronger with age than auditory sentence structure (Cooper & Collacott, 1995). In this case, the expressive language is weak, the speech delays or slows among ageing adults. According to Rasmussen & Sobsey 1994, longitudinal studies conducted on forty (40) years old adults with downs syndrome shows much loss in communication skills in particular receptive language. The study also indicated that dyspraxia sets in, a central nervous system condition affecting speech production. In addiction, this disorder affects the accuracy in gesture use. The ability to respond to auditory stimuli weakens with age meaning that the affected may not respond to when addressed verbally. There are difficulties in comprehending vocals, in this case the person with downs syndrome is poor in understanding spoken language and word discrimination. Scholars questions whether the language decline was as a result of loss of memory, or part of adult-ageing process related to downs syndrome. Receptive language in downs syndrome individuals (40-49 years) shown to be low in comparison to the younger individuals (Dalton and Crapper-McLachlan, 1986).
