Man plans suicide after Alzheimer's

[Bigplants]

I believe it was a short story.probably 1980 or earlier. A man with beginning Alzheimer's plans his own death once it becomes too advanced. I can't remember how he planned it. I remember the scene was an office. I think I remember something about a file cabinet. Sorry I can't offer more

This keeps bothering me. I keep remembering stories, blowing like tumbleweeds across the prairie of my mind, and keep coming back to thinking, "This sounds like something Mike Resnick would write."

Though I don't remember anything that matches this meager description, the closest story to this that master tearjerker Mike Resnick wrote is "Down Memory Lane".

A man, telling the story in the first person, watches his beloved wife get a diagnosis of dementia, lives it up while they can, and takes care of her until he can't do so by himself any more. He keeps a backup gun thinking he could use it to end it quickly for both of them if it becomes hopeless. He can not bring himself to do so.

The last part of the story tells his journal entries, which, sadly, follow a similar pattern to that of Charlie's journals in "Flowers for Algernon".

This may not be the requested story, and it is much newer than 1980, but the description isn't much to go on.
