Hedge dying

Question

Hi, my box hedge plants are starting to die from the bottom up. As they surround my garden and are a feature, I need to stop any further dying off. A neighbour says it’s “caterpillar disease” and there is no cure, is this correct?

It may be a blight. Here's more info:

I suggest clipping a few of the bad stems from the bushes and take them in to a local nursery or to a county extension office to identify the problem and learn how to treat it.
