Signs and Symptoms

Myotonic dystrophy (DM) is more than just a muscle disease. Both DM1 and DM2 affect several aspects of physical and mental functioning to varying degrees and with variable scope.

The following sections discuss different problems that can occur, although many people with the disease have only some of them. Most of these symptoms can be lessened with treatment. See Medical Management for information on current therapies.
