Take notes of meetings and read them before going to sleep or at the time your brain is performing better. For example, I tend to have problems in the afternoon, so I try to do most of my work in the mornings or late evenings.

Make sure not to make enemies, as they will use this against you. In that sense, try to make meetings flow and if something requires a decision from you, ask people to create diagrams and explanations in a wiki like internal page, like confluence, so you can digest it on your time to make the correct the decision. Similarly, create yourself any diagram or descriptions/points you want to discuss beforehand to take it to the meetings. Maybe make them available before the meetings as well so people can provide you with info you will have processed before the meeting and during the meeting it will be easier to make decisions. Have a good night sleep. Have a good routine and eat well. Take any food supplement you may think you require, and consult a physician if you need medication. I've been taking lion's maine recently and has helped a lot with memory cognition. Unfortunately there is no easy solution here, except to work harder to overcome your problem. An alternative to working harder is getting less tasks to focus on, manage less people, reduce the amount of workload so you can still deliver good work, or even step down from workload intensive roles, like C- ones. Or if you can't step down but have some budget, have your own sharp assistant to help you out.
