ALS is the third most common neurodegenerative disease after Alzheimer’s and Parkinson’s diseases. The worldwide ALS prevalence is 4.42 per 1,00,000 people. (Xu et al., 2020) The onset of the disease is most common in people in their 40s to 70s, and 90% of cases occur without any family history of the disease. However, approximately 10% of these cases are familial ALS.
Once the disease develops, the patient gradually becomes immobile, has difficulty eating and speaking, and is unable to breathe. A ventilator can sustain life, but paralysis progresses throughout the body. The average life expectancy with a ventilator is 7 years. (Hayashi et al., 2020)
Unfortunately, there is no curative therapy; however, there are drugs that can delay the time to ventilator use by a few months. Only the motor nerves are affected (degenerated), and patients gradually lose the ability to move their bodies while remaining conscious. The disease is also characterized by a very heavy burden of nursing care, as the patient requires around-the-clock care.
There are several ongoing studies worldwide to achieve a fundamental cure.
This website provides the latest information on ALS clinical trials, based on scientific evidence.
