ALS, also known as amyotrophic lateral sclerosis or Lou Gehrig's disease, is a progressive neurodegenerative disorder that affects the nerve cells in the brain and spinal cord. It is a complex disease, and the exact cause of ALS is still not known. While some cases may be caused by genetics, there is no definitive cause of ALS.
Genetic Causes of ALS
Some cases of ALS may be caused by genetics, meaning that it is inherited from a parent. In these cases, the gene responsible for causing the disease is passed down from a parent to a child. It is estimated that 5-10% of all ALS cases are inherited from a parent.
Environmental Causes of ALS
Environmental factors may also play a role in the development of ALS. Exposure to environmental toxins such as lead, mercury, and certain chemicals have been linked to increased risk of developing ALS. Additionally, certain viral infections and head trauma may increase the risk of developing ALS.
Other Risk Factors for ALS
In addition to genetic and environmental causes, certain lifestyle factors may increase the risk of developing ALS. Smoking cigarettes, having a sedentary lifestyle, and being overweight or obese have all been linked to an increased risk of developing ALS.
Diagnosing ALS
ALS is diagnosed through a combination of tests, including blood tests, imaging tests, and nerve conduction tests. The diagnosis of ALS is based on the clinical presentation of symptoms, as well as the results of these tests.
Although there is still no definitive cause of ALS, research is ongoing to better understand the factors that may contribute to the development of the disease. While there is no cure for ALS, there are treatments available to help manage symptoms and slow the progression of the disease.
