A little over 5,600 people in the U.S. are diagnosed with ALS each year. (That's a new victim every 90 minutes.) It is estimated that as many as 30,000 Americans have the disease at any given time. 80% of the people with ALS are men and 93% of patients are Caucasian. Most people who develop ALS are between the ages of 40 and 70, with an average age of 55 at the time of diagnosis. However, cases of the disease do occur in persons in their twenties and thirties.
Abstract. Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder marked by progressive loss of motor neurons, muscle wasting, and respiratory dysfunction. With disease progression, secondary symptoms arise creating new problematic conditions for ALS patients. Amongst these is pain.myotrophic lateral sclerosis (ALS) is a progressively lethal motor neuron disorder that affects roughly 2 in 100,000 individuals each year [ 1 â 3 ]. Commonly referred to as Lou Gehrigâs disease, ALS is characterized by degeneration of primary motor neurons in the cortex, brainstem, and spinal cord.
