Language use and disturbances in old age.

The short literature overview is organized around the idea that during our life course there is a classic competition between accumulated experience and the increased metacognitive reflection possibilities as the positive side, and the rusting of fast mental processes, mental slowdown with age as a negative side. This is non trivially crossed by the issue that in language, grammar corresponds to the early stabilizing procedural system, while vocabulary is a system that remains open during all our life regarding its acquisition, but shows signs of access problems due to the age sensitivity of the declarative memory system. Language and speech in this regard as well are subject to multiple determination: different age parameters characterize its acquisition and usage. I show some summaries of age related changes in grammar, vocabulary, and articulation. The review specifically discusses the possible role of age related in memory and executive functions during physiological ageing. In this domain as well, the new IT system brought in new environmental and research method challenges.
