4 Possible Causes of ALS and MS


ALS and MS are two neurological disorders that can have a devastating impact on a person’s quality of life. Although the root causes of these conditions are not yet known, there are several possible explanations for how they develop.

Autoimmune Response

One theory is that ALS and MS are caused by an autoimmune response. This means that the body’s immune system mistakenly attacks healthy nerve cells, causing them to break down and die. This could explain why they compare people with these conditions who often have elevated levels of certain antibodies in their blood linked to those who have ALS or MS.

There is evidence that autoimmune response plays a role in the development of ALS and MS. In ALS, for example, researchers have found antibodies against motor neurons in the spinal cord and brain. In MS, autopsies have revealed areas of inflammation and damage caused by the body’s own immune cells.

While the exact cause of these diseases is still unknown, it is thought that genetic factors may play a role in predisposing someone to an autoimmune disease. Additionally, environmental factors, such as infections or stress, may trigger the body’s immune system to begin attacking healthy cells. Autoimmune diseases like ALS and MS are complex, and researchers are still working to understand all of the factors that contribute to their development. However, the role of autoimmune response in these diseases is clear. Further research into this area may help to improve our understanding of these conditions and lead to new treatments.

Rogue Proteins

Another possibility is that ALS and MS are caused by rogue proteins called prions. Prions are abnormal proteins that can cause other proteins to change shape and function improperly. This can lead to the death of nerve cells and the development of neurological symptoms.

In ALS, these proteins are known as superoxide dismutases (SOD1), and in MS, they are known as myelin-associated glycoprotein (MAG). Both of the proteins are involved in the repair and maintenance of nerve cells, but when they become damaged or dysfunctional, they can cause cell death and tissue damage. This can lead to the symptoms seen in ALS and MS, such as muscle weakness, paralysis, and loss of coordination. Right now, there is currently no cure for either disease, but treatments are available that can help slow the progression of the disease and improve quality of life.


It’s also possible that infections play a role in the development of ALS and MS. For example, some research has suggested that the Epstein-Barr virus (which causes mono) may be linked to an increased risk of MS. Additionally, other viruses, such as Lyme disease, have been linked to ALS development.

While it is not clear how these viruses might contribute to the development of ALS or MS, it is possible that they could trigger an autoimmune response that attacks the nervous system. Alternatively, they could directly damage nerve cells, leading to cell death and the symptoms of these conditions.

More research is needed to determine the exact role that infections may play in ALS and MS. However, if infections do contribute to these conditions, it may be possible to develop treatments that target the viruses or the immune response to help prevent or slow the progression of these diseases.

Genetic Mutations

Finally, it’s possible that genetic mutations play a role in the development of these conditions. Scientists have long suspected that genetic mutations play a role in the development of ALS and MS. Now, new research has provided strong evidence to support this theory. For example, people with certain mutations in the SOD1 gene are more likely to develop ALS. Additionally, people with certain mutations in the C9ORF72 gene are more likely to develop both ALS and MS.

Importantly, many of these mutations were found in genes that are involved in the function of mitochondria – the powerhouses of cells. This suggests that dysfunctional mitochondria may play a key role in the development of both ALS and MS.

The findings provide important insights into the causes of these devastating diseases and could lead to the development of new treatments that target mitochondrial dysfunction.

While the exact cause of ALS and MS is still unknown, there are several possible explanations for how these conditions develop. Further research is needed to determine the precise causes of these neurological disorders. If you suffer from ALS or MS, don’t lose heart. Treatments are available to help your quality of life be the best it can be.
