The impact of informal caregiving on cognitive function and wellbeing in Canada

<p><strong>Background: </strong>With a rise in the aging population and a consequential rise in persons diagnosed with dementia comes an increase in the number of informal caregivers who are caring for a loved one. The objective of the proposed study was to assess the neurocognitive and psychological effects of caring for a person with dementia or a related neurodegenerative disease in a sample of Canadian informal caregivers.</p> <p><strong>Methods: </strong>Fifty-seven informal caregivers of a person with dementia or a related neurodegenerative disease (mean age = 66.26, SD = 7.55) and 97 non-caregivers (mean age = 69.16, SD = 4.84) were recruited. Neuropsychological measures of attention, cognitive flexibility, verbal learning, delayed recall, and verbal fluency were examined, and questionnaires related to perceived stress, quality of life, mood, and self-esteem were administered.</p> <p><strong>Results: </strong>Caregivers made more errors on a measure of cognitive flexibility (<em>p</em> = 0.02), generated fewer words on measures of phonemic fluency (<em>p</em> < 0.01) and semantic fluency (<em>p</em> < 0.001), and learned significantly fewer words on a list-learning task (<em>p</em> < 0.01). Caregivers also reported experiencing significantly more perceived stress (<em>p</em> < 0.001), lower quality of life (<em>p</em> < 0.001), and were more likely to meet the cut-off for clinically significant depressive symptoms on a self-report scale (<em>p</em> < 0.001).</p> <p><strong>Conclusion: </strong>These data contribute to a growing body of literature that consistently points to the need for immediate action to improve the welfare of caregivers.</p>
