Muscle weakness can be a symptom of many chronic conditions, acute infections, or even a side effect of certain medications. Neuromuscular disorders, such as muscular dystrophy, multiple sclerosis, and myasthenia gravis, are conditions that affect the nerves that control voluntary muscles. Muscular dystrophy, in particular, is a group of inherited diseases that cause progressive weakness and loss of muscle mass due to abnormal genes that interfere with the production of proteins needed for healthy muscles. Myopathies, on the other hand, refer to diseases that affect skeletal muscles, and they can be inherited or acquired later in life. Infectious conditions, such as the flu, Lyme disease, and HIV, can also lead to muscle weakness. In some cases, muscle weakness can be an indicator of a serious condition, such as a stroke, and immediate medical attention is crucial.

What You'll Learn
Muscular dystrophy
There are several types of muscular dystrophy, each caused by a genetic mutation particular to that type. The most common variety is Duchenne muscular dystrophy, which usually occurs in young boys. Other types include Myotonic, Facioscapulohumeral (FSHD), Congenital, and Limb-girdle. Symptoms of the most common variety begin in childhood, but other types may not surface until adulthood.
The main sign of muscular dystrophy is progressive muscle weakness, which can lead to trouble walking and using arms. Other complications include breathing problems, a curved spine (scoliosis), heart problems, and swallowing difficulties. Respiratory infections can also become an issue, so vaccination for pneumonia and influenza is important.
Treatment options for muscular dystrophy include medications, physical and occupational therapy, and surgical procedures. Newer drugs such as eteplirsen (Exondys 51) and golodirsen (Vyondys 53) have been approved to treat Duchenne muscular dystrophy. Heart medications and range-of-motion exercises may also be beneficial. People with muscular dystrophy should be monitored throughout their lives by a team of specialists, including neurologists, rehabilitation specialists, and therapists.

Neuromuscular disorders
There are many types of neuromuscular disorders, including muscular dystrophies, multiple sclerosis (MS), amyotrophic lateral sclerosis (ALS), autoimmune diseases (such as Graves' disease, myasthenia gravis, and Guillain-Barré syndrome), thyroid conditions (like hypothyroidism and hyperthyroidism), and endocrine myopathies (where hormones interfere with muscle function). Muscular dystrophy, a group of inherited diseases, is one of the most common neuromuscular disorders, causing weakness and wasting away of muscle tissue. It interferes with the creation of new muscle and results in progressive degeneration due to abnormal or insufficient structural support proteins. While there is currently no cure for neuromuscular disorders, treatments like medications, physical therapy, occupational therapy, and surgery can help manage symptoms and enhance patients' quality of life.
Myopathies are diseases that affect the skeletal muscles (those connecting to bones). They can be inherited, passed down in families, or acquired later in life due to other medical disorders, infections, medications, or electrolyte imbalances. Congenital myopathies typically affect all muscles and may not be progressive, while acquired myopathies can cause episodes of weakness interspersed with normal strength. Mitochondrial myopathy, caused by mitochondrial defects, can lead to muscle weakness and impact other organ systems like the heart, brain, and gastrointestinal tract.
Autoimmune/inflammatory myopathies occur when the body attacks itself, causing muscle function problems. Toxic myopathy results from toxins or medications interfering with muscle structure or function, and endocrine myopathies are caused by hormonal imbalances affecting muscle function. Metabolic myopathies are caused by gene mutations affecting enzymes needed for normal muscle function and movement, often manifesting as exercise intolerance or muscle pains.
In summary, neuromuscular disorders encompass a wide range of conditions affecting nerves, muscles, or their junction. While these disorders currently lack a cure, various treatments can help manage symptoms and improve patients' lives. Myopathies, a subset of neuromuscular disorders, can be inherited or acquired, with various subtypes impacting muscles in different ways and often causing muscle weakness. Understanding and treating these disorders is an ongoing area of medical research and practice.

Infectious conditions
Several infectious conditions can cause muscle weakness. Here are some infectious conditions that can lead to muscle weakness:
Flu
The flu virus can cause muscle weakness and various other symptoms such as fever, cough, sore throat, and fatigue. It is a highly contagious viral infection that affects both children and adults.
Lyme Disease
Lyme disease is an inflammatory condition transmitted by the bite of an infected tick. It can cause acute or chronic symptoms, including muscle weakness, joint pain, fever, and fatigue.
Meningitis
Meningitis is a severe infectious condition that leads to inflammation in the brain and spinal cord. It can cause muscle weakness and other serious symptoms, such as severe headache, neck stiffness, nausea, and sensitivity to light.
HIV
Human Immunodeficiency Virus (HIV) can lead to progressive muscle weakness, especially in individuals who do not receive treatment. It is a viral infection that attacks the immune system and can cause severe complications if left untreated.
Polio
Polio myositis can cause muscle weakness and sensitivity. Individuals who have had polio may also experience post-polio syndrome, which is characterized by muscle weakness.
Myositis
Myositis is a group of conditions that cause muscle inflammation, leading to weakness, swelling, and pain. It is often triggered by viral infections, such as the common cold or flu. While there is no cure for myositis, its symptoms can be managed through various treatments, including immunosuppressant drugs and physical therapy.
Polymyositis
Polymyositis is an inflammatory condition that causes muscle irritation and weakness. It is believed to be triggered by a virus or an autoimmune reaction. Polymyositis can affect muscles throughout the body, making even simple movements difficult. While there is no cure, its symptoms can be managed through treatments such as anti-inflammatory medicines.

Autoimmune diseases
One example of an autoimmune disease that weakens muscles is myositis. Myositis is a rare autoimmune disease that inflames and weakens muscle fibres. The immune system attacks healthy muscle tissue, resulting in inflammation, swelling, pain, and eventual weakness. The areas of the body affected by myositis vary from patient to patient, but it often involves the muscles in the upper arms and thighs, causing difficulty in raising arms above the head and rising from a chair. It can also affect the lungs, causing difficulty breathing, and the esophagus and jaw muscles, leading to swallowing difficulties. Women are more than twice as likely to be diagnosed with myositis, and most patients are between 30 and 60 years old when diagnosed.
Myositis can be challenging to diagnose because it mimics or overlaps with other autoimmune diseases like lupus, Sjogren's, scleroderma, and rheumatoid arthritis. A diagnosis involves a medical history, physical exam, and assessment of muscle strength and rashes. Doctors may also order blood tests to check for elevated muscle enzymes and specific autoantibodies associated with myositis. Other diagnostic tests include muscle magnetic resonance imaging (MRI), electromyogram, and nerve conduction velocity studies.
While there is no cure for myositis, early treatment can improve muscle strength and function and slow or stop the progression of the disease. Treatments include physical therapy, speech therapy to address speech difficulties, and dietary changes to ensure adequate nutrition and ease swallowing. Emotional support through counselling or support groups is also important for managing the disease.

Genetic disorders
There are a variety of genetic disorders that can cause muscle weakness. One notable group of such disorders is muscular dystrophy, which refers to a group of more than 30 genetic conditions that cause progressive muscle weakness and loss of muscle mass. The symptoms of muscular dystrophy get worse over time, and there is currently no cure. However, medications and therapy can help manage symptoms and slow the course of the disease.
Muscular dystrophy is caused by mutations in the genes responsible for healthy muscle structure and function. These mutations interfere with the production of proteins needed to form healthy muscle. There are several genes and possible genetic mutations that play a role in muscle function, which is why there are so many different forms of muscular dystrophy. The most common form, Duchenne muscular dystrophy, usually occurs in young boys. Other types don't surface until adulthood. The specific signs and symptoms of muscular dystrophy depend on the type and the age of onset, but they often include trouble walking, difficulty using arms, and breathing problems.
Another group of genetic disorders that can cause muscle weakness is the neuromuscular disorders. These disorders affect the nerves that control voluntary muscles and the nerves that communicate sensory information back to the brain. When the nerve cells (neurons) become unhealthy or die, communication between the nervous system and muscles breaks down, resulting in muscle weakness and atrophy. There is currently no cure for neuromuscular disorders, but research is being done on genetic therapies and new medications in hopes of finding one.
In addition to muscular dystrophy and neuromuscular disorders, there are other genetic disorders that can cause muscle weakness. For example, inflammatory myopathy, progressive muscle weakness, and cardiomyopathy (heart muscle weakness) may produce symptoms similar to those found in some forms of muscular dystrophy, but they are caused by different genetic defects. Genetic testing and counseling can help identify inherited conditions and characterise the specific type of muscular dystrophy or other genetic disorder causing muscle weakness.
