als meaning medical
amyotrophic lateral sclerosis, ALS, Lou Gehrig's disease(noun) thickening of tissue in the motor tracts of the lateral columns and anterior horns of the spinal cord; results in progressive muscle atrophy that starts in the limbs. ALS is typically a disease that involves a gradual onset. The rate at which ALS progresses can be quite variable from one person to another. Although the mean survival time with ALS is three to five years, many people live five, 10 or more years. Symptoms can begin in the muscles that control speech and swallowing or in the hands, arms, legs or feet. Not all people with ALS experience the same symptoms or the same sequences or patterns of progression. For the broader group of diseases, see Motor neuron disease. Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease and motor neurone disease (MND), is a specific disease that causes the death of neurons which control voluntary muscles. Some also use the term motor neuron disease for a group of conditions of which ALS is the most common. Kamel and colleagues found that the variant allele (ALAD 2) of the polymorphism denoted as ALAD K59N was positively associated with an approximate twofold increase in risk of ALS after adjustment for age, sex, region, education, and physical activity. 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 demise. When the motor neurons die, the ability of the brain to initiate and control muscle movement is lost. Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, is a progressive degeneration of nerve cells that control muscle movements. The disease, the most common motor neuron disease among adults, became known as Lou Gehrig's disease after the New York Yankee's Hall of Fame first baseman. Gehrig's career ended in 1939 because of the condition. About 30,000 patients in this country have the disease and about 5,000 are diagnosed with ALS every year. ALS, or amyotrophic laterals sclerosis, is a progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord. A-myo-trophic comes from the Greek language. A means no. Myo refers to muscle, and Trophic means nourishment – No muscle nourishment. When a muscle has no nourishment, it atrophies or wastes away. Medical Definition of amyotrophic lateral sclerosis. : a rare fatal progressive degenerative disease that affects pyramidal motor neurons, usually begins in middle age, and is characterized especially by increasing and spreading muscular weakness—abbreviation ALS; called also Lou Gehrig's disease.
