Gosh, that would seem unlikely at your young age. Okay, couple of questions. How is your sleep? I have had two times in my life, once when I had two young kids (toddler and baby) and I literally was woken up every hour or hour and a half a night. And the other was when I had a job that kept me up until 1 am and then I could fall asleep and had to get up at 5:30 am the next day. I started doing very strange things . . . left keys in ignition and drained my battery, started coffee pot with no pot under it, put meat in slow cooker and never turned it on. I was cognitively affected by lack of sleep.
Anything like that going on with you?
Another thing is hormones and thyroid. Have you had any blood draws to check these? A slow or hypothyroid can cause forgetfulness and memory issues. You'd probably have other things like really long cycles with periods not being regular or being just every 2 to 4 months.
Depression and stress can also cause this.

Read that and see what you think. You'll get a banner to get their newletter. Click out of it and then go back in and you won't get the banner. (tip).
Something else that comes up on when I read about this is nutritional deficiency. Something else to look in.
Give those a read and see if there are any things worth talking about with your doctor. By the way, do you have kids?
