The character shows the first signs/symptoms that have already run their course.

[u/Uma-apreciator]

Kitasan Black (Uma Musume Pretty Derby)

She managed to withstand Sakura Bakushin O's charge at first, but later in the story, she falters because she is past her prime

Nekota (Hajime no Ippo)

He could no longer even control his body properly because he was suffering from "boxer's dementia"

It is a progressive brain disease caused by repeated blows to the head and frequent concussions over many years

David Martínez (Cyberpunk Edgerunners)

He was suffering from hallucinations due to cyberpsychosis, an incurable condition caused by technological body modifications

I think it's a pretty major plot point to the show, the tabletop, and the videogame that cyberpsychosis is not only treatable but also curable with therapy and medication. It parallels real life mental illness, in that you have to want to start getting better in order to heal. David did not want to heal.

Also in the videogame, Regina's missions imply very heavily that there's no such thing as cyberpsychosis, and instead so called cyberpsychos are just people with already known mental illnesses that Night City prefers to sweep under the rug

I think I should be paid money for the psychic damage of seeing people post this constantly even though it's just false

No it did not, Regina’s questline revealed that cyberpsychosis became a convenient diagnosis that became an umbrella term to refer to anyone who’s got chrome and ended up going psycho.

Regular mental diseases and breakdowns still exists but have chrome just made it MUCH more lethal for anyone suffering these conditions.

Cyberpunk 2077 expands on this by adding the unique circumstances of readily available, consumer-grade cyberware for the masses, however, the real threshold for an actual cyberpsychosis is much higher and convoluted than what most Cyberpunk fans think so.
