Does Biden have a neurological disorder in the years 2020-2024?

Prediction market on manifold. As by an official announcement or trustworthy reports. The question can resolve anytime until 2030, as long as the source credibly mentions that the neurological disease already was present in the years 2020 - 2024 (including 2024). Early-stage disease and pre-cursors count, such as early-stage Alzheimer's. Resolves no by the end of 2030 if there's no strong evidence in favor of yes by then.

Liquidity: $1,000. Resolves: 1/1/2031.
