Have you considered that parts of the brain are basically data storage and that once full certain parts are simply overwritten with new data?
I'm reminded of it all the time, and it's actually Asperger's brain, as mine is filled with obscure trivia, while I can't for the life of me recall the names of the members of my family, when they were born or when weddings and anniversaries are.
Yet, I can watch a rerun of the original Law & Order series, and will recall each and every episode, though not having viewed them in the last twenty or thirty years.
What I really need is an updated queuing manager!
