Not sure if herbicide spray-drift may be involved here but take a few sample leaves in a sealed plastic envelope to a local nursery (that sells lilacs) or, better yet, an extension service office if you have a nearby one. They should be able to check for lilac blight. Its treatment involves pruning and destroying the affected areas. A bacteria causes that problem and wet weather helps it "bloom". I am not sure that moisture problems would cause brownout only on the top leaves but check anyways.

See below:

Can you post a picture of the shrub and a close up of the affected leaves (top and bottom)?
