Myositis (my-o-SY-tis) is a rare type of autoimmune disease that inflames and weakens muscle fibers. Autoimmune diseases occur when the body's own immune system attacks itself. In the case of myositis, the immune system attacks healthy muscle tissue, which results in inflammation, swelling, pain, and eventual weakness.
Types of neuromuscular disorders include: Amyotrophic lateral sclerosis (ALS) Charcot-Marie-Tooth disease. Multiple sclerosis.
Muscular dystrophy is a group of diseases that cause progressive weakness and loss of muscle mass. In muscular dystrophy, abnormal genes (mutations) interfere with the production of proteins needed to form healthy muscle. There are many kinds of muscular dystrophy.
The main symptoms are weak, painful or aching muscles. This usually gets worse, slowly over time. You may also trip or fall a lot, and be very tired after walking or standing. If you have any of these symptoms you should see a GP.
Viruses or bacteria may invade muscle tissue directly, or release substances that damage muscle fibers. Common cold and flu viruses, as well as HIV, are just a few of the viruses that can cause myositis.

According to The Myositis Association, more than 95% of these patients are still alive more than five years after diagnosis. Many experience only one period of acute illness in their lifetime, while others struggle with symptoms for years.
Myositis means inflammation of the muscles that you use to move your body. An injury, infection, or autoimmune disease can cause it.
After a careful history and physical exam to document the pattern of weakness in muscles, a doctor who suspects myositis likely will order a blood test to check the level of creatine kinase (CK), an enzyme that leaks out of muscle fibers when the fibers are being damaged. In PM, the CK level is usually very high.
If left untreated, the muscle inflammation in myositis can lead to permanent muscle damage and loss of muscle mass. Myositis can be associated with problems in other organs like the joints and the lungs. In dermatomyositis, there is usually a rash or skin inflammation in addition to the muscle inflammation.
Symptoms of muscle disease may include muscular weakness, rigidity, loss of muscular control, numbness, tingling, twitching, spasms, muscle pain and certain types of limb pain.
The most common is Duchenne muscular dystrophy (DMD). The next most common is Becker muscular dystrophy (BMD). Symptoms are almost the same as Duchenne, but less severe.
Electromyography. An electrode needle is inserted into the muscle to be tested. Electrical activity is measured as you relax and as you gently tighten the muscle. Changes in the pattern of electrical activity can confirm a muscle disease.
Having myositis can also lead to other parts of the body being affected, such as the skin, lungs or heart. Sometimes myositis can affect the muscles that carry out tasks such as breathing and swallowing.
Treatment of myositis can include anti-inflammatory medications and intravenous administration of gamma globulin, with new and promising medications being introduced on a regular basis. Exercise and physical therapy are also useful tools to ease myositis' physical impact.
In addition to these common myositis mimics, certain other neurologic diseases (such as ALS and cervical myelopathy), endocrinopathies (such as hypothyroidism), and infections (like toxoplasmosis) can also be mistaken for myositis, Dr.
While sporadic inclusion body myositis is a progressive disease, life expectancy for those with sIBM is usually the same as for those without the disease. In fact, IBM patients usually don't die from the disease, but from complications (often preventable) that are associated with it.
Myositis is a disease that makes your immune system attack your muscles. It causes chronic inflammation — swelling that comes and goes over a long time. Eventually, this inflammation makes your muscles feel increasingly weak. It can also cause muscle pain.
Generally, the onset occurs between age 30 and 60. Signs and symptoms of polymyositis vary considerably from person to person, which can make it difficult to diagnose.
This means that my blood cells are invading my muscle tissue and causing the painful inflammation. This, in turn, causes the muscles to weaken and some patients end up in wheelchairs, bedridden or have the ability to use assistive devices to walk while others are still able to walk unassisted.
Physical exercise has been shown to reduce inflammation, reduce fatigue, increase stamina, and build muscle, even in patients with myositis.
