If you forgot where you left your keys, or you walked into a room and forgot why you went in there, is that normal? Here are 3 reasons your memory could be slipping and what you can do to prevent it:

First: Your blood sugar is high. That can cause memory loss, according to the Mayo Clinic. So, if you come from a family with a history of diabetes, protect your memory by getting tested regularly, eating well, and staying active.

You could also be mentally fuzzy if you snore – because it’s a big warning sign of sleep apnea. That’s a condition in which the throat collapses, cutting off oxygen for seconds at a time, up to 30 times an hour during the night. And that affects brain health.

Lastly: You may be forgetful if you’re low on vitamin B12. The older we get, the more trouble we have absorbing vitamin B12. And after age 65, a deficiency can mimic the effects of Alzheimer’s! So get your levels checked! A simple supplement could be the solution.
