“…The "encyclopaedic" trait of semantic memory mentioned above captures only its general outline. Representations sustaining semantic material are structured in a complex architecture of abstract ideas, words and images characterised by associations and hierarchies (see for instance [15]). Although a detailed focus on the psycholinguistic theories of semantics is beyond the scope of this review, being aware of such complexity is a necessary pre-requisite to comprehend the mechanisms by which semantics is stored and managed at a biological/neurological level, because it is at this level that AD pathology affects the nervous system.…”

Diagnostic and Prognostic Role of Semantic Processing in Preclinical Alzheimer’s Disease

Relatively spared during most of the timeline of normal aging, semantic memory shows a subtle yet measurable decline even during the pre-clinical stage of Alzheimer's disease. This decline is thought to reflect early neurofibrillary changes and impairment is detectable using tests of language relying on lexical-semantic abilities. A promising approach is the characterization of semantic parameters such as typicality and age of acquisition of words, and propositional density from verbal output. Seminal research like the Nun Study or the analysis of the linguistic decline of famous writers and politicians later diagnosed with Alzheimer's disease supports the early diagnostic value of semantic processing and semantic memory. Moreover, measures of these skills may play an important role for the prognosis of patients with mild cognitive impairment.
