What're the symptoms of myotonic dystrophy?

Myotonic dystrophy is a form of muscular dystrophy in which the muscles have difficulty relaxing. Muscle myotonia (abnormally prolonged muscle contraction, with difficulty relaxing) may develop soon after birth or begin as late as early adulthood, especially affecting the hands, wrists and tongue. In teens, it can cause a number of problems, including muscle weakness and wasting (where the muscles shrink over time), cataracts, and heart problems. A person with myotonic dystrophy has difficulty relaxing his or her grasp, especially in the cold. Myotonic dystrophy affects heart muscle, causing irregularities in the heartbeat. It also affects the muscles of the digestive system, causing constipation and other digestive problems. Myotonic dystrophy may cause cataracts, retinal degeneration, low IQ, frontal balding, skin disorders, atrophy of the testicles, and insulin resistance. It can also cause sleep apnea--a condition in which normal breathing is interrupted during sleep. Myotonic dystrophy increases the need for sleep and decreases motivation. Severe disabilities do not set in until about 20 years after symptoms begin. Most people with myotonic dystrophy do not require a wheelchair, even late in life.

More information on muscular dystrophy

What is muscular dystrophy? - Muscular dystrophy is a group of inherited diseases that are characterized by weakness and wasting away of muscle tissue.
What types of muscular dystrophy are there? - There are nine types of muscular dystrophy including Duchenne muscular dystrophy, Becker muscular dystrophy, facioscapulohumeral muscular dystrophy.
What causes Duchenne muscular dystrophy (DMD)? - Duchenne muscular dystrophy is a rapidly progressive form of muscular dystrophy. It is caused by a defective gene.
What're the symptoms of Duchenne muscular dystrophy? - Symptoms of Duchenne muscular dystrophy include progressive muscle weakness of the legs and pelvis, mental impairment or heart problems.
What causes Becker's muscular dystrophy? - Becker muscular dystrophy is a type of dystrophinopathy which include a spectrum of muscle disease caused by mutations in the DMD gene.
What're the symptoms of Becker's muscular dystrophy? - Symptoms of Becker-type muscular dystrophy are similar to those of Duchenne dystrophy, but they are milder and begin later.
What causes limb-girdle muscular dystrophy? - Limb-girdle muscular dystrophy is an inherited disorder, it may be inherited as a dominant, recessive, or X-linked genetic defect.
What're the symptoms of limb-girdle muscular dystrophy? - Symptoms of limb-girdle muscular dystrophy include progressive muscle weakness in the shoulders and hips, together with breathing problems.
What causes facioscapulohumeral muscular dystrophy? - Facioscapulohumeral muscular dystrophy involves progressive muscle weakness and loss of muscle tissue.
What're the symptoms of facioscapulohumeral muscular dystrophy? - Symptoms of facioscapulohumeral muscular dystrophy may begin during infancy, late childhood, or early adulthood.
What causes myotonic dystrophy? - Myotonic dystrophy is caused by an inherited gene defect. Myotonic dystrophy is the most common form of adult muscular dystrophy.
What're the symptoms of myotonic dystrophy? - Symptoms of myotonic dystrophy include muscle weakness and wasting, cataracts, heart problems, constipation and other digestive problems.
How is muscular dystrophy diagnosed? - Diagnosis of muscular dystrophy involves a medical history and physical exam to determine the distribution of symptoms and to rule out other causes.
What's the treatment for muscular dystrophy? - Treatments for muscular include decreased mobility and dexterity, contractures, scoliosis, heart defects, and respiratory weaknesses.
