According to the National Institutes of Health, 20,000-30,000 adults are afflicted with amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease (named after its most famous sufferer). The disease is described as “rapidly progressive, invariably fatal neurological disease.” Usually sufferers of the disease will succumb within 3 to 5 years of diagnosis, though 10% of those afflicted have survived up to ten years. Most diagnoses occur in patients between the ages of 40 and 60, and men tend to suffer from the disease more than women.
For people with a properly functional nervous system, voluntary movements are caused by the motor neurons of the brain relaying signals to the motor neurons of the spinal cord, which in turn relay the signals to the muscles. In sufferers of ALS, these motor neurons rapidly degenerate and die, essentially cutting off the part of the brain that controls voluntary movement from the rest of the body. If a person’s muscles do not receive the signals to move or perform other actions from the brain, they degenerate, or atrophy, from lack of use. Typically, the earliest symptoms of ALS include twitching or stiffness of muscles, random muscle weakness in the arms and legs, and slurred speech.
Eventually, those afflicted with the disease lose all strength in their muscles, therefore losing the ability to voluntarily move their extremities. Once the neurons connecting the brain to the diaphragm (the muscle beneath the lungs that controls breathing) degenerate, the sufferer will be required to go on a ventilator. Most deaths from ALS occur due to respiratory failure.

Exercise tests are for the most part exactly what they sound like. They involve using machines commonly found in the local gym, such as treadmills and exercise bicycles, to measure how the cardiovascular system responds to physical activity. Such tests can tell doctors about both the severity of preexisting cardiovascular disease or allow these same doctors to measure recovery after a cardiac event such as a myocardial infarction (heart attack). The SSA requires that all exercise tests that it purchases follow acceptable protocols.
“Organic Medical Disorders” as described in Listing 12.02 are “psychological or behavioral abnormalities associated with a dysfunction in the brain.” Specifically, they are mental ailments that can be traced to something amiss in the brain, detectable in laboratory tests such as MRIs. This is in contrast with “psychiatric disorders” which are diagnosed behaviorally. While the term “organic mental disorder” and its various permutations are virtually obsolete in the practice of psychiatry (including being removed from the DSM-IV), the SSA still uses the term when describing the category.
SLE primarily strikes people between the ages of ten and fifty. Women are ten times more likely to be affected than men. African Americans and Asians are afflicted more often than those of other races.
Red blood cells are rich in a substance called hemoglobin, a protein that carries oxygen molecules to all other cells. In adults, hemoglobin-rich red blood cells comprise 35%-52% of a person’s blood; this percentage is known as the hematocrit level. Normal variations in the hematocrit level depend largely on factors such as gender and physical fitness. Anemia occurs when a person’s hematocrit levels drop too low, indicating that the red blood cells are not properly transporting oxygen to other parts of the body.
Even though obesity was deleted from the listings, SSA recognizes that obesity is a medically determinable impairment that is often associated with disturbance of the respiratory system, and disturbance of this system can be a major cause of disability in individuals with obesity. The combined effects of obesity with respiratory impairments can be greater than the effects of each of the impairments considered separately. Therefore, those deciding whether disability should be granted must consider any additional and cumulative effects of obesity.
