Abstract: Amnestic mild cognitive impairment (aMCI) is characterized by a greater episodic memory decline than expected for age and education, without significantly interfering with functioning. Each year, 10 to 15% of aMCI older adults develop Alzheimer's disease (AD). Stress figures among predictors of aMCI progression to AD, possibly through neurotoxic effects of stress hormones such as cortisol. Mindfulness based interventions (MBI), shown effective to reduce stress on the psychological and physiological (i.e., cortisol) levels, appear as a relevant novel approach to prevent cognitive decline associated with AD. The aim of this doctoral memoir was to evaluate the impact of a MBI on the psychological and physiological stress of older adults with aMCI, compared to a psychoeducation based intervention (PBI). The preliminary data, presented in Chapter 4, suggest the potential benefits of MBI and also PBI to reduce physiological and psychological stress, respectively, among older adults with aMCI. Further research is essential considering that older adults have few interventions available and compromised quality of life. Indeed, improving well-being and productivity of older adults with aMCI, through interventions such as MBI or PBI, could lead to considerable gains regarding AD’s socio-economic burden, a major public health challenge for Canada's aging population
