What does this tree need to become healthy looking again?

Hi- I live in Dallas Tx. I have what I'm told is a slippery/red elm tree in my front yard. Its very tall and probably pretty old, not sure how old but my home was built in 1925. I did some research and it is showing signs similar to yellow elm disease (Images attached) . Leaves started yellowing and slowly falling in August. Still plenty of yellow leaves in the tree and a few green ones. The Elm tree 10 yards away (measuring from tree top to tree top) is just fine so maybe it's some other problem or its just typical for this species. I think this happened last year also but we sort of figured it was normal for this type of tree but now that I compare it to my neighbors green leafy elm tree 10 yards away, I see something might be up with my tree. What does this tree need to become healthy looking again or is this typical behavior for this species of Elm? Anyone have a suggestion?

Any changes/construction/chemicals in root zone? Soil test?
Hows root flair and root system?
One pic looks like it could be bacterial wetwood. Hows DED and yellows in your region? Dead trees in the neighborhood?
Id cut symptomatic limbs and send to a diagnostic lab if you can answer the first few questions

IF disease and root zone changes are inconclusive,
Then I would get rid of all ground cover vines, etc. in root zone and mulch that baby as far out to drip line or further as you can handle...

First off, with no disrespect to the tree owner intended, do you really feel confident with diagnosing this tree?

I think your first step is find a certified and reputable Arborist in your area who can assess the tree and it's surroundings. Someone on here has got to be able to help with that! Good luck with your tree.
 
Last year at the ISA conference I listened to a municipal arborist from Texas speak about drought stress. I think she was from San Antonio (not sure though).
I also don't know if your weather over the past 5 or even 10 years has been anything like what she spoke about (I don't know your weather patterns).
She spoke about what they had been doing to combat the sever drought. So it's probably not beyond consideration to look at drought stress as a cause. I know our trees are really suffering locally due to lack of water. The red maples are turning early, the oaks are scorching bad in some areas.
Unfortunately by the time signs like these are seen its too late to have an aesthetic impact for this year.
With that said, you should hire a local arborist that knows the area and the trees to give you their opinion.
Good luck
