I am only seventeen but l am starting to forget things. It was not so bad at first, l would forget things that happened a week ago, but now l forget things that happened yesterday, and even things that happened earlier in the day. What is happening to me?
No, I am not using drugs.

Oh gosh those are the signs of alzheimer is but then you are still young. Hm.. u should go see a doctor. R u getting enough sleep or stressed out? l heard walnuts are really for memory so try some.Hope you get ur memory back to normal.

That is a tough one. l am no doctor, but it is possible you're very distracted. Either that, or you simply do not care enough about the things you need to remember. Sounds like you've got a flaw. Write stuff down if you can.

See the doctor.

l assume you are not using drugs.

Did you forget that you asked this question?

Extreme stress? Do u struggle with depression? l believe long-term depression can cause memory problems. Do u suffer from sleep deprivation or an eating disorder? These could be contributing factors. While the researchers looked at people over 50, could it be high blood sugar? http://news.bbc.co.uk/1/hi/health/2720011.stm ''Researchers have used state-of-the-art imaging techniques to probe differences in brain activity among individuals with different versions of a gene important in nerve cell formation. They find that variations in a gene called brain-derived neurotrophic factor (BDNF) can determine whether or not a person is good at remembering past events.'' http://genomenewsnetwork.org/articles/08_03/memory.shtml ''STRATEGIES PEOPLE EMPLOY FOR REGULATING EMOTIONS AFFECT MEMORY FOR EVENT, ACCORDING TO A NEW STUDY

Attempting To Control One is Reactions To An Event Has 'Cognitive Costs' That Weaken Memory'' http://apa.org/releases/emotionmem.html

There r probably many other possibilities.

How to improve memory:
-healthy balanced diet, exercise, & plenty of sleep
-cut back on caffeine
-mental stimulation: word search, sudoku, crossword puzzles, reading a book
-walking away from a stressful situation & doing something peaceful

Someone told me to check the effects of aspertame (in diet sodas n stuff) cuz it screws with ur memory. It freaked me out cuz l have alot of the symptoms.one of which is memory loss.
This may not be ur case at all.. but l thought I'd pass on the message. just in case. This is one of the articles that was referred to me:
