Unpredictable, frustrating and, at times, embarrassing memory lapses can be common. So if frequent bouts of forgetfulness are causing you stress and worry, take note: there is most likely a simple explanation.

Occasional memory lapses—what you ate for dinner last night or where you parked your car at the mall—are normal.
