Hi Eva,
At this time, datasets do not have any integration into the announcements/messages module to allow discussion threads like you've seen for Lists for each individual record.
You could create your own script on the Participant View page by customizing it and having it create a box that will allow you to enter in discussion notes and then submit them to the announcement/message forum within the study, but considering how many potential records there are within the study, this could create a lot of messages and organization may be difficult to maintain.
And yes, the reason why it doesn't appear when it is closed is due to that specific discussion being done. If a discussion is not truly finished, it shouldn't be set to closed. If the discussion was set to closed by mistake, you can go back into the Messages web part and edit the discussion message back to Active to make it re-appear.
