==Overview==
Common risk factors in the development and progression of amyotrophic lateral sclerosis largely remain unknown.
Other common risk factors associated include: [[Age]], Smoking, [[oxidative stress]].

==Risk Factors==
*Defective [[mutation]] in chromosome 21, inherited in an [[autosomal dominant]] pattern.
===Common Risk Factors===
*The children of those diagnosed with familial ALS have a higher risk factor for developing the disease; however, those who have close family members diagnosed with sporadic ALS have no greater a risk factor than the general population
 
*Prolonged exposure to a dietary neurotoxin is one suspected risk factor in Guam; the neurotoxin is a compound found in the seed of the [[cycad]] ''[[Cycas circinalis]]'',<ref>Bains J, et al.

*Common risk factors in the development of [Amyotrophic lateral sclerosis] include:
*According to the [[ALS Association]], military veterans are at an increased risk of contracting ALS. In its report ALS in the Military,<ref>{{cite web| url=http://www.alsa.org/files/pdf/als_military_paper.pdf |title=ALS in the Military |accessdate=2008-05-01 |publisher=The [[ALS Association]] |date=2007-05-17}}</ref> the group pointed to an almost 60% greater chance of the disease in military veterans than the general population. For Gulf War veterans, the chance is seen as twice that of the general population in a joint study by the [[United States Department of Veterans Affairs|Veterans Affairs Administration]] and the DOD.

Overview

Common risk factors in the development and progression of amyotrophic lateral sclerosis largely remain unknown. Other common risk factors associated include: Age, Smoking, oxidative stress.

Risk Factors

Common Risk Factors

  • Common risk factors in the development of [Amyotrophic lateral sclerosis] include:
    • Smoking
      • Cigarette smoke might be considered an established risk factor for Sporadic Amyotrophic lateral sclerosis (level A rating, 3 class II studies, 1 class III study).[1]
    • Chemical exposure
      • ALS has shown an association with exposure to agricultural chemicals such as pesticides, fertilizers, herbicides, insecticides, and formaldehyde.[2]
      • Among all the heavy metals that might be associated with ALS, lead exposure seems to be studied the most possibly due to the ALS-like symptoms experienced by people exposed to high concentrations of lead.[3]
    • Radiation
    • Diet
    • Genetic causes[6]
