A substantial literature has reported that stress negatively impacts on cognitive processes. As dementia caregiving can be stressful, it has been hypothesized that the challenges of dementia care may increase caregivers’ own vulnerability to cognitive decline.
Our findings are in line with the idea that greater psychological stress in response to challenges associated with dementia care predicts poorer caregiver executive functioning, particularly among caregivers with low CR (cognitive reserve). However, these findings are cross sectional; it is also possible that poorer executive functioning contributes to greater caregiver stress.
