I've sometimes wondered if all the dementia "symptoms" is just an act. It would be a pretty evilly brilliant plan to orchestrate the "dementia Biden" in public, all while orchestrating all the damage behind the scenes. He only has to show himself to be totally cognizant at critical times, such as debates and major speeches, which he seemingly has been able to do. People claim he must be drugged up when he appears cognizant, but what if that is how he actually is?
