The conclusion from an abstract of an article:

Oral creatine administration may improve short-term memory and intelligence/reasoning of healthy individuals but its effect on other cognitive domains remains unclear. Findings suggest potential benefit for aging and stressed individuals. Since creatine is safe, future studies should include larger sample sizes. It is imperative that creatine should be tested on patients with dementias or cognitive impairment.1

Christian said I should take a look at creatine monohydate as a possible supplement. Christian and my Ph.D. classmate and old friend, John S. have used it to help with their weightlifting. I need to get back to weightlifting as I get older, partially because it helps maintain bone density, but also because I like it. That might have been a reason to start taking the stuff all by itself, but when I watched a video on creatine Christian sent me, it talked about help for short term memory during age related cognitive decline. I looked into it. It is not completely clear yet, but there seems to be evidence that it helps. So I ordered a bottle from Walmart and am going to give it a try.
