Muscle atrophy is the wasting or thinning of muscle mass. It can be caused by disuse of your muscles or neurogenic conditions. Symptoms include a decrease in muscle mass, one limb being smaller than the other, and numbness, weakness and tingling in your limbs.
Muscle wasting (atrophy) is the thinning of muscle tissue, a natural consequence of aging called sarcopenia. Sarcopenia can be accelerated by malnutrition or immobilization due to a sedentary lifestyle, hospitalization, or disease (e.g., arthritis or stroke).
Cachexia (wasting syndrome) is a condition that causes significant weight loss and muscle loss. It often affects people with severe chronic diseases like advanced cancer and heart disease. A cachexia diagnosis often means that the end of life is near.
Muscular dystrophy is a group of inherited diseases that causes weakness. They also cause wasting away of muscle tissue. There are multiple types of muscular dystrophy. Each type leads to loss of strength, increasing disability, and possible deformity. The most common muscular dystrophy is Duchenne muscular dystrophy.
Conditions that can cause muscle wasting include muscular dystrophy, multiple sclerosis, and spinal muscular atrophy. Treatment may include dietary changes and exercise. Learn...
The medical definition of sarcopenia is the gradual loss of muscle mass, strength and function. The condition commonly affects the elderly population and is thought to occur due to aging. Sarcopenia can greatly impact your quality of life by reducing your ability to perform daily tasks.
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.
Because of this, these diseases may eventually result in muscle wasting, or loss of muscle mass. This may involve loss of strength and function in one or more muscles. Sometimes paralysis may occur. This article discusses primary and secondary muscular system diseases.
In a person who hasn't had a traumatic injury, high blood levels of creatine kinase (CK) suggest a muscle disease. Genetic testing. Blood samples can be examined for mutations in some of the genes that cause types of muscular dystrophy. Muscle biopsy. A small piece of muscle can be removed through an incision or with a hollow needle.
Progressive muscular atrophy (PMA) is a rare disease that affects lower motor neurons, brain cells that provide muscles and glands with the nerves needed to function correctly. People with this disease experience wasting and loss of muscle mass. The condition eventually leads to loss of voluntary muscle control.
