I did a Google search for "talking over people." Most of the posts were about why people do it and how to work around it, but I was looking for tips on how to do it myself.  I found a thread called Wait vs. Interrupt Culture that not only contained a lot of perspective on that topic, but one of the posters also mentioned about how his conversation is shaped by his aphasia. The only time I'd heard the term aphasia was an episode of Deep Space Nine. But what the poster described reminded me of some of my own issues communicating. I looked up aphasia on Wikipedia, and found that my issue falls into the category of anomic aphasia. The difference with me is that the word usually comes to me. It couldl take anywhere from 3 seconds to 5 minutes, but the word always comes. It wasn't clear from Wikipedia or from the poster whether the word ever comes to them or whether it is just lost.  Of course, even a 3 second gap in conversation can throw things off. The thing that got my attention was that it is linked to brain damage and Alzheimer's.  I think I'll go back to my primary care manager and follow up on this.
