Have you tried attention and focus field for ADHD? I’m not an expert, but this sounds like it could help.
You should also try dopamine receptor repair since dopamine plays a big role in memory and keep using brain regeneration for a few hours every night. Plasma related fields could also help big time.
Also, ground yourself more and meditate to calm the mind. Stress is a killer, and should be avoided or mitigated at all cost. Also, do you sleep well at night? Are you heating healthy foods? Are you exercising and walking regularly?
