Split hand syndrome is a potential sign of amyotrophic lateral sclerosis (ALS). This means that some of the muscles in the hand are weak and thin (atrophied), while others are less affected.

Loss of muscle mass, also called muscle wasting or atrophy, can happen gradually as part of getting older or more suddenly due to underlying medical conditions. Other factors can contribute, like ...

(BOSTON) — Muscles waste as a result of not being exercised enough, as happens quickly with a broken limb that has been immobilized in a cast, and more slowly in people reaching an advanced age.

About 80% of people with cancer suffer from significant muscle wasting, or loss of muscle tissue, and 30% of these patients die from this condition. New research in mice finds that the severity of ...

Muscles are made to move. Stretching and contraction stimulate biochemical pathways within muscle that maintain tissue health. When movement slows—when a broken limb is immobilized in a cast, for ...

Muscle atrophy is a prevalent condition in today's societies, but many of the roles that mitochondria play in the process remain unclear. In a recent study, researchers investigated how muscle atrophy ...

Infections can present with many different symptoms, and one common symptom is wasting, which involves the loss of fat and in extreme cases lean muscle as well. Researchers in the lab of Salk ...

A protein called B cell lymphoma 6 (BCL6) could be key to maintaining healthy muscle mass, and potentially could be used to combat muscle wasting conditions in humans, a study in mice suggests.
