In the middle of a conversation with my DH, a response will have nothing to do with the subject matter. Or it ends abruptly, sometimes with no memory of the conversation. Inappropriate responses or jokes having nothing to do with conversations.
Other times, you would never think anything is wrong and it makes me wonder if it was just a lack of interest, then it starts again. Such a puzzle, I am taken by surprise.
Is this a beginning stage of dementia? Memory seems off at times, but not bad. Just this strange conversational style happening often enough to make me know something is going on.
