Good news for grandparents! Babysitting grandchildren just one day per week reduces the risk of dementia and Alzheimer’s disease. A new study published by The Journal of The North American Menopause Society followed 120 grandmothers in Australia and found that cognitive functioning is higher for grandmother’s who babysit one day per week. But the data also suggested that grandmother’s who babysit five or more days per week did not reap similar cognitive benefits and had lower working memory and processing speed. (Thanks Mom!)
