Research a natural product called NOOTROPICS. It has the Psychostimulatory effects ( as Ritalin is a stimulant) and it boosts cognition; plus it has 13 additional supplements. I am 52 & have been at this researching a long time to get off the Ritalin & the horrible side effects. I take Noocor ( found on Amazon ) it works 100 times better! Google Nootropics & research, it may be what you’re looking for. Good luck & God bless.
