[Multiorgan manifestations in myotonic dystrophy type 1]

Myotonic dystrophy is one of the most common, autosomal dominantly inherited adult-onset muscle disorders. Two types of the disease are known: type 1 is characterized by distal weakness and myotonia, but type 2 is associated with proximal weakness and milder clinical course. It is also called as Steinert Disease, which affects the heart conduction system, the internal secretional glands, the ocular lens as well as carbohydrate-, fat metabolism and gonadal functions. These systemic symptoms have high impact on the quality of life and might impact on patients' survival. Here we would like to emphasize these clinical conditions and the diagnostic possibilities. We hope our recommendations can help neurologists and general practitioners to achieve an optimal and individual care for patients suffering from this muscle disease.
