Amyotrophic lateral sclerosis, or ALS, is an adult-onset neurodegenerative disease that causes paralysis and ultimately death when the nerves enervating the lungs cease to carry the signals needed for breathing. The disease has what is called a "focal onset," where paralysis starts with an arm or a leg and spreads throughout the body as motor neurons in the spinal cord and brain die off. Early diagnosis of the disease has not been possible because of a lack of known biomarkers indicative of ALS, but scientists believe that cellular changes within spinal neurons occur before symptoms are detectable, and these changes could serve as useful biomarkers that can aid in earlier diagnosis.

Like many neurodegenerative conditions, amyotrophic lateral sclerosis is a disease of aging. His case corroborates previous work suggesting FUS-based ALS can hit the young, and it highlights the extraordinary variability in the disease. In addition to the early onset, the young man in the case study was unusual in that his weakness and muscle atrophy affected mostly his right arm, shoulder and neck.

Bulbar-onset amyotrophic lateral sclerosis ALS is the most common form of the disease among patients 80 and older at disease onset, a factor that seems to contribute to shorter survival for these patients compared with younger ALS patients, a retrospective study has found. ALS is a progressive neurological disorder in which motor neurons — the nerve cells responsible for controlling voluntary muscles — gradually degenerate and die, causing muscles to shrink, or atrophy, and become weaker. According to two European epidemiological studies, in recent years, the steady increase in life expectancy and population aging in Western countries may be contributing to an increased number of much older ALS patients — a group often excluded from clinical trials and poorly characterized in terms of disease presentation, progression, and prognosis. In this study, researchers focused on examining and characterizing a population of ALS patients who were 80 or older at disease onset, in particular their survival, compared with younger ALS patients.

ALS is characterized by a progressive degeneration of motor nerve cells in the brain upper motor neurons and spinal cord lower motor neurons. When the motor neurons can no longer send impulses to the muscles, the muscles begin to waste away atrophycausing increased muscle weakness. ALS does not impair a person's intellectual reasoning, vision, hearing or sense of taste, smell and touch.

Amyotrophic lateral sclerosis ALS is one of a group of disorders known as motor neuron diseases. It is characterized by the progressive degeneration and eventual death of nerve cells motor neurons in the brain, brainstem and spinal cord that facilitate communication between the nervous system and voluntary muscles of the body. Ordinarily, motor neurons in the brain upper motor neurons sent messages to motor neurons in the spinal cord lower motor neurons and then to various muscles.

The initial symptoms of ALS can be quite varied in different people. One person may have trouble grasping a pen or lifting a coffee cup, while another person may experience a change in vocal pitch when speaking. ALS is typically a disease that involves a gradual onset.

A growing collection of anecdotal stories raises the possibility that nerve injury in an arm or a leg can act as a trigger for the development amyotrophic lateral sclerosis, or ALS -- a progressive neurodegenerative disease also known as Lou Gehrig's disease, named after the famous New York Yankee who died of it in The connection between ALS and athletes runs deeper than a single ballplayer; people who engage in intense physical activities, such as professional athletes and people in the military, are more likely to be affected by ALS. In some, the disease seems to start after an injury -- muscle weakness at the site of the injury slowly spreads to new areas until weakness in the muscles responsible for breathing causes suffocation. Now, researchers at the University of Illinois at Chicago are the first to demonstrate that a peripheral nerve injury can trigger the onset and spread of the disease in an animal model of ALS.

ALS is often called Lou Gehrig's disease, after the baseball player who was diagnosed with it. Doctors usually don't know why ALS occurs. Some cases are inherited.
