Most of the time it's caused by fungal infections in the vascular system of a tree, blocking the flow of water. It's usually introduced into the tree by boring insects. The shortage of water is what causes the lower branches to die first. Applying water to the tree can help, but it's no cure. I think it's just a matter of time before the whole tree dies.
