What Is Muscular Dystrophy?
Muscular dystrophy is a type of disease that causes the muscles in your body to lose strength and mass. As your muscles become weaker over time, it may be hard for you to do normal activities.
Depending on the type of muscular dystrophy you have, you may have problems walking, breathing, or swallowing. Many types of muscular dystrophy start showing symptoms during 人妻中出视频hood, but muscular dystrophy can develop at any age.
Treatment
There is no cure, but medication and therapy can help manage the worst symptoms and can help make daily activities easier.
Muscular Dystrophies We Treat

Duchenne Muscular Dystrophy (DMD) is a genetic disorder that prevents your muscles from working correctly. Over time, it can make normal, day-to-day activities hard. It is the most well-known type of muscular dystrophy, and can also cause heart problems and obesity.
Becker Muscular Dystrophy (BMD) is similar to Duchenne鈥檚 Muscular Dystrophy but is usually less severe.
(EDMD) usually affects the muscles in the upper arms and lower legs first. It is a less common type of muscular dystrophy.
(FSHD) affects the muscles in your face, shoulders, upper arms, and lower legs. It can also affect the muscles in your eyes, ears, and heart. Patients usually start experiencing muscle weakness by the time they turn 20 years old.
(LGMD) can show signs from early 人妻中出视频hood to late into the adult years. It weakens the muscles in your shoulders and hips but can also affect your heart and diaphragm.
(OPMD) is different from other types of muscular dystrophy disorders because it usually doesn鈥檛 affect people until they are over 40 years old. It weakens the muscles in the face, especially around the eyes. It is a very rare disorder.
Myotonic Muscular Dystrophy
(MMD1) is the most common type of muscular dystrophy that doesn鈥檛 start showing signs until the adult years. It usually affects the muscles in your face, neck, arms, and hands. It can cause slurred speech and temporarily cause your jaw to lock.
(MMD2) is similar to type 1 MMD and shares most of the same symptoms. However, type 2 is usually less severe.
Hereditary Neuropathies

Hereditary neuropathies are a type of genetic disorder that affect your peripheral nervous system, the nervous system that does not control the brain and spinal cord. Hereditary neuropathies usually affect the muscles in your arms, legs, hands, and feet.
Types of Hereditary Neuropathies
Charcot Marie Tooth Disease is a genetic disorder that affects the nerves that make your feet, legs, hands, and arms work normally. The disease weakens your motor and sensory nerves, which carry signals (or instructions) to your brain.
Spinal Muscular Atrophy (SMA) weakens your muscles. It affects motor neurons in your spinal cord. Motor neurons are nerve cells that communicate messages to your brain and allow your muscles to work normally.
Friedreich鈥檚 Ataxia first affects the muscles in your legs and then spreads upward towards your arm and chest muscles, making it hard to walk. It can also cause hearing and vision loss. It is very rare and usually begins developing during 人妻中出视频hood or the teen years.
weakens the muscles in your face and throat (bulbar muscles), arms, and legs. The disorder damages motor neurons, the nerve cells in your spinal cord and brain. It usually starts showing signs during adulthood.
Congenital Muscular Dystrophies & Myopathies
人妻中出视频
If you have congenital muscular dystrophy, you have had it since you were born. It is a type of muscular dystrophy that is inherited, meaning that parents can pass the disease onto their 人妻中出视频ren through their genes.
Myopathies cause problems in how your skeletal muscles contract and move. Skeletal muscles let you control voluntary movements like walking, sitting, and chewing.
Types of Congenital Muscular Dystrophies & Myopathies
听causes severe muscle weakness and loss of muscle strength. Most people with Merosin Deficient Congenital Muscular Dystrophy are born with the disorder because their LAMA 2 gene has a mutation, or change, that鈥檚 different from other people. Many people with the disorder will need special devices to help their muscles move correctly.
听are types of disorders caused by mutations (or differences) in collagen genes in the body. These genes include COL6A1, COL6A2, and COL6A3. Bethlem and Ullrich are two types of this disorder.
听is a broad category of disorder caused by mutations, or abnormal changes, in the LMNA gene.听
听cause muscle weakness, most often in the muscles in the face, neck, and limbs. These types of disorders are caused by mutations (changes) in the following genes: ACTA1, KBTBD13, CFL2, KLHL40, NEB, TNNT1, TPM2, and TPM3.听
听is a disorder that causes muscle weakness and can start showing symptoms from birth to the early adults years. People with this condition may also have droopy eyelids, abnormally shaped feet, or a spine that abnormally curves from side to side. Mutations (or changes) in the BIN1, DNM2, and MTM1 genes cause this disorder.听
Channelopathies

A channelopathy is a type of disease that makes it hard for you to control how your muscles move. Channelopathies happen when small molecules inside your cell - called ions - don't work the way they should.
Types of Channelopathies
听weakens your skeletal muscles, the muscles you use to move your arms, legs, and other parts of your body. Myotonia can affect any muscles in your body, but it most often affects the leg muscles. The two main types are Thomsen disease and Becker disease.听
, also called听Eulenberg disease, usually starts in infancy or 人妻中出视频hood. It causes muscle stiffness and prevents muscles from relaxing. Muscle stiffness usually gets worse with repeated movements.听
听causes episodes or periods of muscle weakness. It can also cause dangerous changes in your heart鈥檚 rhythm, called arrhythmia. The two most common types of period paralysis are hyperkalemic paralysis and Andersen-Tawil syndrome.听
Inflammatory Myopathies

Inflammatory myopathies cause inflammation and weakness in your muscles. These types of diseases can also cause muscle pain.
Types of Inflammatory Myopathies
听weakens your hip, thigh, upper arm, and neck muscles. Polymyositis can make it hard to get up from a chair, climb stairs, or lift things over your head. The disease can also make it hard to swallow or breathe.听
听causes muscle weakness in your hips, thighs, and neck. It is similar to polymyositis, but causes a red or purple-colored rash on your knees, elbows, knuckles, or eyelids.听
听slowly and gradually inflames and weakens the muscles in your body. The disease may affect muscles on only one side of your body. It can also make it hard to swallow. Symptoms usually don鈥檛 begin to show until after age 50.听
Metabolic Muscle Diseases

Metabolic muscle diseases interrupt your body's normal metabolic process of taking energy from your food. These types of diseases change the chemical reactions your metabolism uses to break down sugars, fats, and carbohydrates.
