myotonic dystrophy vs muscular dystrophy

Myotonic Dystrophy is a multi-system disease, which can initially present with symptoms of ptosis, ophthalmoplegia, extraocular myotonia, and decreased visual acuity. Muscular dystrophy (MD) refers to a group of nine genetic diseases that cause progressive weakness and degeneration of muscles used during voluntary movement. 800-572-1717 | ResourceCenter@mdausa.org Myotonic dystrophy (DM) is one of the muscular dystrophies. When functionally debilitating, myotonia in from myotonic dystrophy type 1 and 2 (DM1 and DM2), which have significant, extra-muscular,systemicmanifestations.Onclinicalgroundsalone,thereisoftenanoverlap among DM2andNDM. This disease is characterized by progressive muscle loss and weakness. The condition is progressive, so symptoms of muscle stiffness and weakness tend to worsen over time. Myotonic dystrophy (DM1) is the most common form of adult-onset muscular dystrophy, and there is a high frequency of insulin resistance due to insulin receptor mRNA splicing defects in muscle tissue. There are two types of myotonic muscular dystrophy, described as type 1 (DM 1) and type 2 (DM 2). However, it's often the smaller muscles that are affected first, such as those in the face, jaw and neck. DM is divided into two types: type 1 affects a gene called DMPK on chromosome 19, and type 2 affects a gene on chromosome 3 called ZNF9. It is estimated that the condition affects about one in 8,000 people worldwide. DM 1 is also called Steinert’s disease. As with other types of muscular dystrophy, myotonic dystrophy involves progressive muscle weakness and muscle wasting. Muscular Dystrophy Statistics. Other types of muscular dystrophy, including limb-girdle, myotonic, fascioscapulohumeral (FSHD), and congenital MD, can affect both men and women. It is the most common form seen in adults and is suspected to be among the most common forms overall. Myotonic muscular dystrophy is the most common form of muscular dystrophy that affects adults and is characterized by myotonia, a symptom involving prolonged muscle stiffening or spasms that worsen in cold temperatures, explains WebMD. It is the most common form of muscular dystrophy that begins in adulthood, usually in a person’s 20s or 30s. Myotonic Dystrophy or dystrophia myotonica (DM) is a genetic disease characterized by progressive muscle degeneration. Myotonic dystrophy may be further classified into two types, and the two types may affect different muscles. In the world, 1 in 3,500 males has MD. There are nine different types of MD: Myotonic: Most common MD in both men and women. Electrodiagnostic and genetic testing help differentiate among the NDMs and between NDM and DM. Approximately 1 in 8,000 people have myotonic dystrophy.. There are congenital forms of MD that are present at the time of birth, whereas other types often develop when a person is in his or her teens or 20s. Myotonic dystrophy is the most common type of late-developing muscular dystrophy.Although it can appear at any age, it usually presents itself in adults in their 20s and 30s. Muscular Dystrophy Association National Office. Myotonic Dystrophy is a tri-nucleotide repeat, autosomal dominant disease characterized by an inability to relax (myotonia) and muscle wasting (muscular dystrophy). Muscular dystrophy (MD) disease in the U.S. affects 1 in 50 million girls and 1 in 5,600 to 7,000 males from ages 5 to 24. Myotonic dystrophy is a disease that affects the muscles and other body systems. Myotonic muscular dystrophy is a common multi-system disorder that affects the skeletal muscles (the muscles that move the limbs and trunk) as well as smooth muscles (the muscles that control the digestive system) and cardiac muscles of the heart. Other symptoms include daytime sleepiness, cataracts and heart problems, notes the Muscular Dystrophy Association. General Overview. Chicago, Illinois 60601. 161 N. Clark, Suite 3550.
