Red Maple disease?
I have a red maple, not any issues last year. This year the top has leaves, and 2 bottom branches. The middle is barren. The branches look to have buds but never opened. Any options for saving tree or is it gone?

From the images it looks like the tree is in a gradual decline. You could prune out the dead and see what happens but my guess is it would just continue to slowly die back.
