How does ALS start and progress? Are people born with ALS or does it develop? Can ALS come and go?

ALS is not something that people are born with because it develops over time. ALS symptoms are usually permanent and do not come and go. ALS can affect any part of the body, but it often starts in the hands, feet, arms, or legs.

The exact cause of ALS is unknown, but about 10% of cases are inherited, while the rest are sporadic. Research suggests a complex interplay of genetic and environmental factors involved in the occurrence of ALS.

There is no cure for ALS and the average life expectancy after diagnosis is 2 to 4 years. However, some people live longer with the help of treatments and supportive care.

As the disease progresses, patients may experience difficulty speaking, swallowing, and performing everyday tasks. Respiratory muscles may also be affected, resulting in breathing difficulties and respiratory failure.

The treatment of ALS aims to slow down the disease progression, prevent complications, and improve the quality of life of people living with ALS.
