Amyotrophic lateral sclerosis (ALS), often referred to as "Lou Gehrig's Disease," is a progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord. Motor neurons reach from the brain to the spinal cord and from the spinal cord to the muscles throughout the body. The progressive degeneration of the motor neurons in ALS eventually leads to their death. When the motor neurons die, the ability of the brain to initiate and control muscle movement is lost. With voluntary muscle action progressively affected, patients in the later stages of the disease may become totally paralyzed.
A-myo-trophic comes from the Greek language. "A" means no or negative. "Myo" refers to muscle, and "Trophic" means nourishment-"No muscle nourishment." When a muscle has no nourishment, it "atrophies" or wastes away. "Lateral" identifies the areas in a person's spinal cord where portions of the nerve cells that signal and control the muscles are located. As this area degenerates it leads to scarring or hardening ("sclerosis") in the region.
As motor neurons degenerate, they can no longer send impulses to the muscle fibers that normally result in muscle movement. Early symptoms of ALS often include increasing muscle weakness, especially involving the arms and legs, speech, swallowing or breathing. When muscles no longer receive the messages from the motor neurons that they require to function, the muscles begin to atrophy (become smaller). Limbs begin to look "thinner" as muscle tissue atrophies.
Amyotrophic lateral sclerosis (ALS)
Amyotrophic lateral sclerosis is a very serious disease. Amyotrophic lateral sclerosis is better known by its common acronym "ALS." If one has ALS, it is key that they seek treatment.

Lou Gehrig's disease is the more common name for amyotrophic lateral sclerosis, a fatal neuromuscular disease which took the life of famous American Baseball player Lou Gehrig. Lou was famous in the 1920's and 30's and had a long and unbeatable record in the game. There is an ALS Association which can provide detailed information on the condition.
Amyotrophic lateral sclerosis (ALS), also called Lou Gehrig's disease, is a progressive neuromuscular disease that weakens and eventually destroys motor neurons (components of the nervous system that connect the brain with the skeletal muscles). Skeletal muscles are involved with voluntary movements, such as walking and talking. The motor neurons transmit the command to move from the brain to the skeletal muscles, which respond by contracting. A person with ALS usually presents with problems in dexterity or gait resulting from muscle weakness, or with difficulty speaking or swallowing. Sphincter control, sensory function, intellectual ability, and skin integrity are preserved. Patients become paralyzed and often require ventilation and surgery to provide a new opening in the stomach (gastrostomy). Loss of respiratory function is ultimately the cause of death.
what is another name for the radius bone? so .. . . ...
There are lots of conditions associated with symptoms of muscle weakening, including multiple sclerosis, polio, amyotrophic lateral sclerosis, myasthenia gravis, and nerve trauma. Are you thinking about one in particular?
