health context of covid-19

Cognitive impairements in Alzheimer's and apparented disorders may lead to the decreased engagement in activities, spetially in moderate and advanced stages of evolution. The lack of stimulation for people with dementia is associated with the risk of challenging behaviors, depressives symptoms, sleeping disorders or faster cognitive deterioration. Those challenges may lead to the increased administration of pharmacological treatments, though the risks of neurleptics use in this population are currently known. In this context, non-pharacological interventions hold a significant place in dementia care.

This research focuses on cognitve stimulation activities. More precisly, our study compares two aproaches using the reading groups. The first type (" usual " reading group) is based on the principle of stimulating those cognitive functions which dicreases with the evolution of dementia. The second (Montessori reading group) approach relies on the idea to use preserved capacities in order to compensate the cognitive impariments.

The aim of our study is to compare the impact of these two non-pharmalogical interventions on non-verbal communication. The collected datas will help analyzing and understanding the internal and behavioral states of people living with dementia. Our study will also extend relfexions about cognitive stimulation groups in care institutions.
