When dementia or Alzheimer's disease sets in, it can make the tasks of daily living - like cleaning and bathing - a problem. That's why senior care services are beneficial for older adults suffering from these conditions. Even before the symptoms set in, in-home elder care can provide assistance, but for men and women who want to retain their memory a little longer, they should continue sipping their regular cup of joe each day.
A study published in the journal Nature Neuroscience found that caffeine can improve focus and attention as well as short-term memory.
Researchers looked at 160 uncaffeinated men and women who had less than 500 milligrams of caffeine each week. The participants looked at various pictures of objects and then took a placebo or a 200-milligram caffeine supplement, which is about how much is in two cups of coffee. The following day, each group looked at another set of pictures with some new photos, as well as new photos that looked similar the ones seen the previous day. Both groups recognized the new and old photos, but the individuals who took the caffeine pill did better at identifying the pictures that were similar but not the same.
