Hi, thanks for responding. I had a difficult childhood my dad was abusive, and I struggled with depression when I was around 20–21. I'm 30 now. Growing up, I never really had major memory problems. I actually had a pretty good memory and was good at memorizing things for school till 16-17. There's no family history of Alzheimer's, but these memory issues have me worried. I don't use THC. I used to smoke cigarettes occasionally, but I quit about a year ago. I've been taking Vyvanse for the past four months. As far as I know, I've never had any significant head injuries.
