Spinal Muscular Atrophy: Background, Pathophysiology, Epidemiology - Medscape
The spinal muscular atrophies (SMAs) comprise a group of autosomal-recessive disorders characterized by progressive weakness of the lower motor neurons. In the early 1980s, Werdnig and Hoffman described a disorder of progressive muscular weakness beginning in infancy that resulted in early death, though the age of death was variable.

Muscle Atrophy - Health Grades
Muscle atrophy, or muscle wasting, results from loss of muscle tissue. Little or no physical exercise and a sedentary lifestyle are common causes of muscle atrophy, in this case called disuse atrophy.

Muscle Atrophy - MedlinePlus
Neurogenic atrophy is the most severe type of muscle atrophy. It can be from an injury to, or disease of, a nerve that connects to the muscle. This type of muscle atrophy tends to occur more suddenly than disuse atrophy.

Muscle Atrophy - MedlinePlus Medical Encyclopedia
Disuse atrophy occurs from a lack of physical activity. In most people, muscle atrophy is caused by not using the muscles enough. People with seated jobs, medical conditions that limit their movement, or decreased activity levels can lose muscle tone and develop atrophy.

Overview: Spinal Muscular Atrophy - MDA
What is spinal muscular atrophy?The muscles closer to the center of the body (proximal muscles) are usually more affected in spinal muscular atrophy than are the muscles farther from the center (distal muscles).

Spinal Muscular Atrophy - NORD (National Organization for Rare Disorders)
Spinal muscular atrophy (SMA) is a group of inherited disorders characterized by a loss of certain nerve cells in the spinal cord called motor neurons or anterior horn cells. Motor neurons receive the nerve impulses transmitted from the brain to the spinal cord (brainstem) and, in turn, transmit the impulses to the muscle via the peripheral nerves.

Muscle Atrophy - MDhealth
Muscle atrophy begins by becoming unsightly, but it can become more serious over time. It is important to address this condition as it begins to take hold to avoid more serious conditions such as heart failure which can result from muscle atrophy.
