ALS (amyotrophic lateral sclerosis), also known as Lou Gehrig's disease, is a progressive neurodegenerative disorder that affects nerve cells in the brain and spinal cord. It is estimated that up to 20,000 Americans have ALS, and it is estimated that the disease may affect as many as 30,000 Americans. The cause of ALS is still unknown, but research suggests that it may be caused by a combination of environmental, genetic, and lifestyle factors.
The Leading Causes of ALS
The exact cause of ALS is unknown, but researchers have identified a number of potential contributing factors. These include:
Genetics: Research suggests that up to 10% of people with ALS have a family history of the disease. The presence of certain genetic mutations may increase the risk of developing ALS.
Environmental Factors: Exposure to certain environmental toxins, such as heavy metals, may increase the risk of developing ALS.
Lifestyle Factors: Certain lifestyle choices, such as smoking, may increase the risk of developing ALS.
Age: The risk of developing ALS increases with age, with most cases occurring in people over the age of 60.
Gender: Men are more likely to develop ALS than women.
Though the exact cause of ALS is still unknown, researchers continue to investigate potential contributing factors in order to better understand the disease and develop effective treatments.
