I lead a stressful life taking care of my husband, who had a stroke two years ago, and managing our household, our finances and our medical care. I am 67 and seem to be bearing up well physically, except for high blood pressure. But I'm worried the stress may be taking a toll on my mind. Lately I have had a difficulty concentrating and remembering. I have forgotten important things, like doctors' instructions and paying my bills, which is very unusual for me. Could stress be causing my memory lapses? If this is the case, what can I do about it?
