If spending time with your grandchildren leaves you feeling both worn out and somehow more alive, science may finally have an explanation for that second part.
A new study published in the journal Psychology and Aging found that grandparents who care for their grandchildren score higher on tests of memory and verbal skills than those who do not. For grandmothers especially, that involvement may actually slow cognitive decline over time.
As we head into Mother's Day weekend, I find that research genuinely moving. The grandmothers I work with are often the quiet center of their families, managing schedules, holding memories, keeping everyone connected. It turns out those grandchildren may be doing as much for them as they are doing for the grandchildren.
The study found that what mattered most was not how often grandparents helped, but what they did together. Helping with homework, playing games, and doing activities that actively engage the mind showed the strongest benefits.
