Answer: If aphids or scale insects aren't responsible for the cupping, curled leaves, there are two other possible causes. Herbicides can cause distorted leaves (either through drift or direct contact) as can viral infections (usually spread by insects). If you have not used herbicides in the vicinity, the problem may well be viral. There are no treatment options other than destroying the plant to control the spread to other plants. Before doing so, though, you may want to take a sample of the problem to your local Cooperative Extension office for positive identification. Best of luck with your fuchsia!
