Full Study Summary:We are doing this study to learn more about the role of a chemical called "glutamate" in Amyotrophic Lateral Sclerosis (ALS). ALS is also known as Lou Gehrig™s disease. It is known that nerve cells called "motor neurons" die in the brains and spinal cords of people with ALS. However, the cause of the cell death is unknown. Researchers think that increased levels of glutamate may be related to the disease progression.
Levels of glutamate and other related chemicals can be measured in the brain using magnetic resonance imaging (MRI). During this study, we will compare the levels of these chemicals in the brain, blood and cerebrospinal fluid (CSF) between people with ALS and people without ALS in order to better understand why ALS happens. This information may be very valuable for future development of new treatments for ALS.
