Considering only the practical advice, and not the medical side, I think that what would help you is to develop a knowledge management system. Journaling to capture tasks, events and learnings you want to remember, and periodic reviews to review, look back, and look ahead.

I discussed my own system here [0].

Personal Knowledge Management helps avoid having to rely on a weak system (your brain), and instead rely on a trusted system.

In it, you can track your goals, vision, plans, progress, lessons learned, and much more.

Writing is really the key skill to focus on. I've stopped relying on my memory a long time ago, and have developed systems that help me remember. Write to forget.
