WHAT IS MUSCULAR DYSTROYPHY

Muscular dystrophy is a group of genetic diseases that cause progressive weakness and degeneration of skeletal muscles. Skeletal muscles are the muscles that are attached to bones and allow for movement. Muscular dystrophy can affect people of all ages, but it is most common in children and young adults.

There are many different types of muscular dystrophy, each with its own set of symptoms and severity. Some of the most common types of muscular dystrophy include:

• Duchenne muscular dystrophy (DMD): DMD is the most common type of muscular dystrophy. It is caused by a mutation in the gene that codes for dystrophin, a protein that helps to keep muscle cells strong and healthy. DMD usually begins in childhood and causes progressive muscle weakness and loss of muscle mass. People with DMD often have difficulty walking and eventually become wheelchair-bound.
• Becker muscular dystrophy (BMD): BMD is a milder form of DMD. It is also caused by a mutation in the gene that codes for dystrophin, but the mutation is less severe than the mutation that causes DMD. BMD usually begins in adolescence and causes slower progression of muscle weakness and loss of muscle mass. People with BMD may be able to walk for most of their lives, but they may eventually need a wheelchair.
• Facioscapulohumeral muscular dystrophy (FSHD): FSHD is a type of muscular dystrophy that affects the muscles in the face, shoulders, and upper arms. It usually begins in adolescence or adulthood and causes progressive muscle weakness and loss of muscle mass. People with FSHD may have difficulty raising their arms above their heads, smiling, or chewing.
• Limb-girdle muscular dystrophy (LGMD): LGMD is a group of muscular dystrophies that affect the muscles in the arms and legs. There are many different types of LGMD, each with its own set of symptoms and severity. LGMD usually begins in adolescence or adulthood and causes progressive muscle weakness and loss of muscle mass. People with LGMD may have difficulty walking, climbing stairs, or lifting objects.

There is no cure for muscular dystrophy, but there are treatments that can help to improve quality of life. Treatments for muscular dystrophy may include physical therapy, occupational therapy, speech therapy, medications, and surgery.

Muscular dystrophy is a serious condition, but with early diagnosis and treatment, people with muscular dystrophy can live long and fulfilling lives.

CAUSE OF MUSCULAR DYSTROPHY

Muscular dystrophy is caused by mutations in genes that control the structure and function of muscle cells. These mutations can lead to a variety of problems, including:

• Reduced production of muscle proteins
• Defective muscle proteins
• Increased muscle cell death

As a result of these problems, muscle cells become weak and eventually die. This leads to progressive muscle weakness and loss of muscle mass.

In most cases, muscular dystrophy is inherited from one or both parents. However, in some cases, the mutations that cause muscular dystrophy occur spontaneously.

TREATMENT OF MUSCULAR DYSTROPHY

There is no cure for muscular dystrophy, but there are treatments that can help to improve quality of life. Treatments for muscular dystrophy may include:

• Physical therapy: Physical therapy can help to improve muscle strength and flexibility, and to prevent contractures.
• Occupational therapy: Occupational therapy can help people with muscular dystrophy to learn how to use adaptive equipment and to perform activities of daily living.
• Speech therapy: Speech therapy can help people with muscular dystrophy who have difficulty speaking or swallowing.
• Medications: There are a number of medications that can be used to treat the symptoms of muscular dystrophy. These medications may include corticosteroids, anti-seizure drugs, and muscle relaxants.
• Surgery: Surgery may be used to treat some of the complications of muscular dystrophy, such as scoliosis (curvature of the spine) and cardiomyopathy (heart muscle disease).

The goal of treatment for muscular dystrophy is to improve quality of life and to slow the progression of the disease. With early diagnosis and treatment, people with muscular dystrophy can live long and fulfilling lives.

Here are some additional information about the treatments for muscular dystrophy:

• Physical therapy can help people with muscular dystrophy to maintain their muscle strength and flexibility. Physical therapists can teach people with muscular dystrophy exercises that they can do at home. They can also help people with muscular dystrophy to use assistive devices, such as walkers or wheelchairs.
• Occupational therapy can help people with muscular dystrophy to learn how to perform activities of daily living, such as dressing, bathing, and eating. Occupational therapists can also help people with muscular dystrophy to use assistive devices, such as adaptive utensils or dressing aids.
• Speech therapy can help people with muscular dystrophy who have difficulty speaking or swallowing. Speech therapists can teach people with muscular dystrophy exercises that can help to improve their speech and swallowing. They can also help people with muscular dystrophy to use assistive devices, such as communication boards or feeding tubes.
• Medications can be used to treat the symptoms of muscular dystrophy. Corticosteroids, such as prednisone, can help to reduce inflammation and improve muscle strength. Anti-seizure drugs, such as baclofen, can help to reduce muscle spasms. Muscle relaxants, such as diazepam, can help to relax muscles and relieve pain.
• Surgery may be used to treat some of the complications of muscular dystrophy. Scoliosis (curvature of the spine) can be treated with surgery to straighten the spine. Cardiomyopathy (heart muscle disease) can be treated with surgery to implant a pacemaker or defibrillator.

The type of treatment that is best for a person with muscular dystrophy will depend on the type of muscular dystrophy they have and the severity of their symptoms. People with muscular dystrophy should work with their doctor to develop a treatment plan that is right for them.
