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]
