Amyotrophic lateral sclerosis 1
Are there any outside factors that make Amyotrophic Lateral Sclerosis worse?
It is thought that there are environmental factors that can cause amyotrophic lateral sclerosis (ALS). These environmental factors include exposure to heavy metals like mercury and lead, toxic/infectious agents like pesticides, specific types of head trauma, or occupational factors. There are also ongoing studies in United States veterans to determine if military-related exposures have contributed to ALS in that population. However, none of these has been conclusively demonstrated to be a significant cause of all sporadic ALS.
