Memory loss

[singlemom827]

At what age do you experience memory loss?  Is it possible to really define an age for women? 

Over the past couple of years I have noticed that I don't seem to remember where I set stuff down at and what I did last week (little stuff).  Now this is starting to effect what I do at home and work.  Here's an example: woke up one morning, started to clean the house and found my car keys laying down.  So I picked them up and continued to clean.  About a couple of hours later I wanted to leave but could not find my keys. In my mind I thought I checked my pockets and they were not there.  Well after four hours later I was in walmart going through my pockets and what do you know there they are. 

Do you think it is time I talk with a doctor about this?  Is there anything out there that might be able to help me?
