Ordinary forgetfulness, or a reason to see a doctor?

Among the most common things people ask about memory, worked through at a careful pace.

Usually everyday	Worth mentioning to your doctor
Losing track of the day, then figuring it out	Not knowing the date or the time of year
Occasionally hunting for the right word	Struggling to follow a conversation or take part in it
Misplacing items from time to time	Frequently losing things and unable to retrace your steps

Drawn from the U.S. National Institute on Aging.
