Hey, I have just turned 18, and within the past 6months to a year my memory has become increasingly bad. I have always had not a great memory, but in the past 6months-1year it has become even worse. I go to the shops, and forget why I am there. My friends try to discuss something I said a few days ago, and I can't even remember saying it. This is starting to scare me how bad my memory is anyone got any idea what could cause this sudden memory lose?
