Professor Agar (CHEM) and graduate student Qi Wang have been conducting research and have discovered potential causes of amyotrophic lateral sclerosis, which is commonly referred to as Lou Gehrig's disease.

Their findings were recently published in the Public Library of Science for Biology.

According to the Web site of the National Institute of Neurological Disorders and Stroke, ALS, a motor neuron disease, "is a rapidly progressive, invariably fatal neurological disease that attacks the nerve cells (neurons) responsible for controlling voluntary muscles." Motor neurons die and therefore are no longer able to send messages to muscles, which "gradually weaken, waste away and twitch. … Eventually the ability of the brain to start and control voluntary movement is lost. Individuals with ALS lose their strength and the ability to move their arms, legs and body. When muscles in the diaphragm and chest wall fail, individuals lose the ability to breathe without ventilatory support."

The disease was first described in 1869 by French neurologist Jean Martin Charcot. The common name for the disease is in honor of the baseball player who died of ALS in 1941. Once a person is diagnosed with Lou Gehrig's disease, the life expectancy ranges between two to five years.

However, 5 percent of the population affected by the disease will live for up to 20 years after being diagnosed, according to the ALS Association's Web site. Qi Wang said people who have Lou Gehrig's disease "gradually lose their abilities. They lose their ability to talk, swallow, and finally they lose the ability to breathe."

The exact causes of Lou Gehrig's disease are unknown; however, Agar explained that the research his lab is currently conducting is "trying to establish what causes the disease, which is unknown for 90 percent [of people affected by the disease]."
