What is the most likely cause of ALS?
About 25 to 40% of all familial cases are caused by a mutation in a gene called C9orf72. Another 12 to 20% result from mutations in the gene SOD1. Mutations in the genes TARDBP and FUS also can cause familial ALS. The C9orf72, SOD1, TARDBP, and FUS genes all are key to the normal functioning of motor neurons.
What are 3 things that can lead to ALS?
Established risk factors for ALS include:
- Heredity. Five to 10 percent of the people with ALS inherited it (familial ALS ).
- Age. ALS risk increases with age, and is most common between the ages of 40 and the mid-60s.
- Sex. Before the age of 65, slightly more men than women develop ALS .
- Genetics.

Most people who develop ALS are between the ages of 40 and 70, with an average age of 55 at the time of diagnosis. However, cases of the disease do occur in people in their twenties and thirties. ALS is 20% more common in men than women.
Is ALS becoming more common?

Are there environmental causes of ALS?
Common environmental factors suspected of contributing to ALS include ethnicity, geographic location, diet and nutrition, exercise and sports, alcohol or tobacco use, occupation, electric shock, exposure to chemicals or radiation, and concussion or other physical injury (“trauma”).
Why do so many athletes get ALS?
Conclusions: Our review suggests that increased susceptibility to ALS is significantly and independently associated with 2 factors: professional sports and sports prone to repetitive concussive head and cervical spinal trauma. Their combination resulted in an additive effect, further increasing this association to ALS.
Can heavy metals cause ALS?
Heavy metal exposure may be a risk factor for ALS. ‘ Lead and mercury have been indicated most often, but manganese and selenium have also been posited because of increased occupational exposure or increase in tissue levels in ALS patients.
What are the risk factors and complications of ALS?
Heredity – Roughly 5-10% of those who have ALS have inherited the condition,this is known as familial ALS.
What are the 6 stages of ALS?
What are the 6 stages of ALS? ALS cannot be cured, but treatments do exist. In general, ALS progression may be divided into three distinct stages: early, middle, and late. The following section offers information about the characteristic symptoms associated with each stage.
