Language function in senile dementia

Abstract The effects of senile dementia on language function were described from analyses of patient performance on the language tasks of naming, sentence correction, sentence disambiguation, story-retelling, and verbal description and four psychological tests reputed sensitive to the disease. While communicative function was not found to be impaired in the normal senescent, marked impairment was observed in patients with senile dementia. Particularly vulnerable was the semantic system and dissociation of semantic capacities from those of syntax and phonology was observed.
