What is ALS?

Abby, Elias and Dr. Janice Robertson of the Tanz Centre for Reserach in Neurodegenerative Diseases (University of Toronto), explain what ALS is and why research is important today.

Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease, is the most common form of motor neuron disease, affecting approximately 2 per 100,000 individuals, with the prevalence rates of about 1-2 per 10,000. 

A definitive diagnosis of ALS is given according to the criteria of El Escorial. This process can take several months as other potential (less severe) causes of disease are considered before a final diagnosis of ALS is given.

ALS attacks the motor neurons of the brain and spinal cord. These neurons are responsible for voluntary muscle movements such as talking, walking, swallowing and breathing. Disease generally starts as a mild muscle weakness that progresses to paralysis and eventual death, usually within 2-5 years from diagnosis. Currently there is no cure and no truly effective treatment, riluzole being the only currently available FDA-approved medication for ALS.

 

More simply…
ALS is a disease that has to do with how your brain relays messages to your muscles. There are specific nerve cells, called motor neurons, these die and are no longer able to bring messages from your brain to your muscles.

This causes your muscles to stop working.
It is progressive, which means, it may affect your legs today, but tomorrow it may affect your arms and fingers, and so on.

 

It does not stop.

What is not affected is your brain. Many people who live with ALS describe the disease as being trapped in your own body.

More About ALS

Anyone can develop ALS.

ALS is NOT contagious. You cannot get it from being around someone who has it. There is a small percentage (5-10%) of cases that are inherited. This is called Familial ALS. All other cases are considered sporadic.

ALS usually strikes people between the ages of 40 and 70 years, however, there are rare cases of younger and older adults.
ALS is usually fatal within two to five years of diagnosis.

How do you know you have ALS? What are the symptoms?

Each person and each case is different. For Christopher Chiu (ALS Double Play’s inspiration), it started with his toe stubbing on the volleyball court along with slower reaction times. Soon there was tightness in his leg with the feeling that he could not stretch it out. Then his leg would spontaneously give way and he would fall. For others it could involve muscle weakness, twitching, cramping.

So what happens?

As the motor neurons die and stop relaying messages to your muscles, all your voluntary muscles become paralyzed; you cannot use them. Your voluntary muscles are all the ones you use at your will, your fingers you use to type and text, your legs to walk, etc. This means that eventually, you cannot walk, feed yourself, dress yourself, and even talking and breathing become difficult.
