Myths about ALS
Myth 1: ALS is an "old-people" disease
ALS can strike any one at any age. The median age for the disease is 54.
Myth 2: ALS is contagious
ALS is not an infection and is not caused by infections or other bacteria. See Myth 3 for more.
Myth 3: ALS is caused by Lyme disease or other infections
ALS is not caused by any type of other disease or infection. This common misconception is due to the fact that some ALS symptoms, such as fatigue, muscle weakness and muscle twitches, are also symptoms of other conditions. As a result, the disease is commonly misdiagnosed. From Dr. Jeffrey Rothstein in the Washington Post:
"Unlike ALS, Lyme is usually treatable with antibiotics. Lyme disease does not cause ALS, and generally in a diagnostic workup, a neurologist can easily separate ALS from Lyme infections, either clinically or with testing. There is no reliable data to suggest that ALS is started by an infection or transmitted by patients to others."
Myth 4: ALS is discriminatory
ALS can affect people of all races and ethnicities.
Myth 5: Stephen Hawking didn't have ALS
Stephen Hawking did have ALS, as the disease progresses in each person differently. Scientists aren't quite sure how he lived so long, but there are two possibilities:
- Developing the disease at a young age (he was diagnosed at 21) causes it to progress slower
- The motor neurons running his diaphragm (breathing muscles) and the motor neurons along his swallowing muscles did not deteriorate
Myth 6: ALS affects only motor activity
It isn't completely known whether ALS may affect more than just motor activity. Again, from Dr. Jeffrey Rothstein in the Washington Post:
"This is a long-standing myth held by physicians and patients: that ALS patients’ minds remain sharp as their bodies deteriorate. But newer studies show that about 20 to 30 percent of patients develop a mild cognitive impairment, while a very small number, about 5 to 10 percent, get severe dementia."
Myth 7: ALS is caused by sports
While there appear to be links to playing sports professionally and having ALS, there are no studies that have successfully proved this theory.
