help building a disadvantage

For a TV series where everything is controlled by the writer and director, it may work. It might work in a 1:1 game, if you're a fan of Phillip K Dick-style unreliable reality. But in a several-players game, the other players will have memories, and may even keep notes. The effects of the disadvantage will be greatly reduced by that, and making it worth the points it sounds like will require heavy-handed and arbitrary GMing.

But if you're determined to have it, you need to look at Cannot Learn with a mitigator as well as Amnesia.

No, it's the opposite of Cannot Learn. People with Cannot Learn still remember events. They just can't acquire new skills. It's basically a hugely mitigated Amnesia, plus a quirk.
