With Alzheimer’s disease and other causes of dementia on the rise, AARP Virginia is offering free workshops in June to share lifestyle tips aimed at helping people stay mentally sharp throughout their lives. The workshops, both in-person and online during Alzheimer’s and Brain Awareness Month, come as an estimated 6.9 million Americans age 65-plus have the disease. Of the current number, an estimated 164,000 live in Virginia, the Alzheimer’s Association says.
