Abstract:

Donostia Longitudinal Study has investigated the effect of non - pharmacological interventions in older adults without cognitive impairment , with mild cognitive impairment and with dementia . The current work is derived from this study and aims to go in depth into the linguistic profile of participants , as well as to perform a first empirical approximation to the effect of multi - type intervention in linguistic constructs . We have had a sample of 395 subjects divided between stages from 1 to 4 of the Global Deterioration Scale ( GDS ) . There have been three groups for each stage : one of them followed an intervention established according to a pattern of decline by stages ; the second performed stimulation tasks without any theoretical background and the third did not receive any kind of intervention . The results showed a better performance in participants with GDS 1 and 2 compared to those with cognitive impairment . Between GDS 3 and 4 , differences were found in vocabulary , writing and semantic fluency , but not in listening comprehension , reading comprehension and phonological fluency . Regarding to the effect of the intervention , an improvement is observed for those variables that measure lexical - phonological processes in those participants who do not suffer cognitive impairment .
