Risk Factors of ALS
There are two major factors that develop the risk of ALS.
Genetics play an important role as specific genes mutate, and there is a risk of developing ALS. There are 5-10% of people who acquire familial ALS through a parent-child transmission.
Age is another risk factor associated with the development of ALS. Below the age of 65, ALS is more common in men than in women.
Men and women above the age of 70 have the same probability of developing ALS.
Studies have shown that postmenopausal women who are active smokers have a higher risk of developing ALS.
- Toxin exposure
Toxins in the environment, such as lead, could also increase the risk of ALS.
- People serving in the military
People serving in the military also have a higher risk of being diagnosed with ALS, although there are no specific reasons identified for this.
