What is ALS?

Amyotrophic Lateral Sclerosis (ALS), also referred to as Motor Neuron Disease (MND) or Lou Gehrig’s disease, is a rare and devastating condition that targets the nervous system, specifically the motor neurons that control voluntary muscle movements.

These neurons progressively degenerate, leading to:

1. Muscle weakness

2. Loss of coordination

3. Speech and swallowing difficulties

4. Breathing complications

Understanding ALS: The Shocking Truth Behind Its Causes

ALS is a very interesting disease: only about 10% of it is associated with a family history. About 90% of it is random. It is almost entirely linked to some sort of environmental toxicity," says Dr. Dayan Goodenowe. pic.twitter.com/vosAJeifQQ

As the disease advances, individuals may lose the ability to walk, speak, eat, and eventually breathe on their own. According to the National Institutes of Health (NIH), "ALS is a rare neurological disease that primarily affects the nerve cells (neurons) responsible for controlling voluntary muscle movement. Most people with ALS die from respiratory failure, usually within 3 to 5 years from the onset of symptoms."

There is currently no known cure for ALS. While the exact causes remain largely unidentified, both genetic and environmental factors are thought to play a role. Research continues to explore experimental treatments and new drugs to help slow the progression.

ALS is fatal, sadly. There are treatments to slow the progression of the disease and give patients a better quality of life. The average life expectancy is 2 to 5 years after diagnosis.
