Exposure to Neurotoxins as Risk Factors for Amyotrophic Lateral Sclerosis
Completed
Conditions studied: Amyotrophic Lateral Sclerosis, ALS
In brief
This study is a follow-up to an earlier study that examined the relationship of This study will examine whether exposure to neurotoxins, such as lead, mercury, solvents, and pesticides, can contribute to amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease. The cause of this degenerative disease of the brain and spinal cord is not well understood. Some studies suggest that exposure to environmental neurotoxins may increase its risk. This follow-up study will examine the relationship of neurotoxin exposure to the interval between the diagnosis of ALS and death. It will also examine the possible roles of genetics, lifestyle and dietary factors in the disease. Information on ALS patients previously enrolled in the study will be used to examine this relationship. No new individuals will be enrolled in the study.
