Older people risk mental decline if they do long hours of caring, UK study shows

A UK study found that caring for someone for 50 hours or more a week can lead to accelerated cognitive decline in middle-aged and older people, while lighter responsibilities have a positive effect on brain health. Caring for only five to nine hours a week can boost brain health, with benefits lasting until older age. The research highlights the importance of considering the impact of caring responsibilities on mental health.
