My caryopteris shrub is slowly 'fading' -- leaves on a branch go limp and then die. Does it have a disease; if so, how do I treat it? Or could it be from the harsh rain and wind we had several weeks ago?

If you had a lot of rain, then it could simply need time to dry out some. It may even have developed a fungal infection as a result. You can cut away any unhealthy branches and treat the shrub with neem oil or other suitable fungicide.
