I am a 38 year old female..who is having sudden memory loss..Yesterday I had to run some errands and was out for about 20 minutes , I was on my way home and about 10 minutes from the house when I made a left turn and that is all I remember..The next thing I knew was that I pulled onto my street , parked and wondered how I was home and how I got there..I lost about 10 minutes of time and can't remember how I got from the left turn 10 minutes away to the house at all...the trip is actually tricky and has several turns on several streets..I can't even remember one detail about the drive , not even a house, car , sign etc... What could have happened? Why can't I remember driving home after a certain point? How did I get home safely with no memory of it?? Should I be concerned..
