Amyotrophic lateral sclerosis (a-my-o-TROE-fik LAT-ur-ul skluh-ROE-sis), or ALS, is a progressive nervous system disease that affects nerve cells in the brain and spinal cord, causing loss of muscle control. ALS is often called Lou Gehrig's disease, after the baseball player who was diagnosed with it.

How does a person get ALS?

Familial (Genetic) ALS

About 5 to 10 percent of all ALS cases are familial, which means that an individual inherits the disease from a parent. The familial form of ALS usually only requires one parent to carry the disease-causing gene. Mutations in more than a dozen genes have been found to cause familial ALS.

What is the life expectancy of someone with ALS?

Although the mean survival time with ALS is two to five years, some people live five, 10 or more years. Symptoms can begin in the muscles that control speech and swallowing or in the hands, arms, legs or feet.

What is the most common first symptom of ALS?

Gradual onset of progressive muscle weakness – which is generally painless -- is the most common initial symptom in ALS.

What is the root cause of ALS?

The exact cause of amyotrophic lateral sclerosis (ALS) is largely unknown, but genetic, environmental, and lifestyle factors are all believed to play a role. The neurodegenerative disease is characterized by the death of motor neurons, which are the nerve cells that control muscle movements.

Why did Stephen Hawking get ALS?

Stephen Hawking told the British Medical Journal that this motor neuron disease has many potential causes, and that his ailment might be due to an inability to absorb vitamins [1]. After numerous tests, the doctors told him that his was an atypical case.

Has anyone ever recovered from ALS?

ALS is fatal. The average life expectancy after diagnosis is two to five years, but some patients may live for years or even decades. (The famous physicist Stephen Hawking, for example, lived for more than 50 years after he was diagnosed.) There is no known cure to stop or reverse ALS.

Does ALS come on suddenly?

As I have mentioned before, ALS does not start abruptly. Consider Lou Gehrig. At first he never dreamed he had a disease. That's the same problem all of our patients face.

What can be mistaken for ALS?

Beware: there are other diseases that mimic ALS.

• Myasthenia gravis.
• Lambert-Eaton myasthenic syndrome.
• Lyme disease.
• Poliomyelitis and post-poliomyelitis.
• Heavy metal intoxication.
• Kennedy syndrome.
• Adult-onset Tay-Sachs disease.
• Hereditary spastic paraplegia.

Where does ALS begin?

ALS often starts in the hands, feet or limbs, and then spreads to other parts of your body. As the disease advances and nerve cells are destroyed, your muscles get weaker. This eventually affects chewing, swallowing, speaking and breathing.

At what age did Lou Gehrig get ALS?

He was diagnosed with ALS on his 36th birthday during a visit with his wife Eleanor to the Mayo Clinic in Rochester, Minnesota, on June 19, 1939.

Is ALS a painful death?

There is no reason that people with ALS have to live in pain. Although only a limited number of people with ALS experience pain, the thought of living with constant pain can be frightening. The disease itself does not cause pain.

Can ALS be prevented?

There is no definite method to prevent ALS. However, people with ALS can participate in clinical trials, the National ALS Registry, and the National ALS Biorepository. This participation may help researchers learn about potential causes and risk factors of the disease.

How did Stephen Hawking live so long with ALS?

Stephen Hawking dies at 76

Jeffrey Elliott, chief of the neuromuscular disorders section at the University of Texas Southwestern Medical Center. “I think part of his longevity may have been because he had a slowly progressive form. Probably it was also due to the exclusive nursing and medical care that he received.”

Can stress cause ALS?

Psychological stress does not appear to play a part in the development of amyotrophic lateral sclerosis (ALS), with patients showing similar levels of prior stressful events, occupational stress, and anxiety as a control group, as well as higher resilience, a study shows.

What celebrities suffered from ALS?

Notable individuals who have been diagnosed with ALS include baseball great Lou Gehrig, theoretical physicist, cosmologist and author Stephen Hawking, Hall of Fame pitcher Jim "Catfish" Hunter, Senator Jacob Javits, actor David Niven, "SpongeBob SquarePants" creator Stephen Hillenburg, “Sesame Street” creator Jon Stone ...

Would ALS show up on MRI?

Scans such as magnetic resonance imaging, or MRI, can't directly diagnose ALS. That's because people with the condition have normal MRI scans. But they are often used to rule out other diseases.

What is the most common misdiagnosis?

Cancer. Cancer misdiagnosis is the most common misdiagnosed disease of all. Different types of cancers are misdiagnosed as well which is why it's important to have a complete medical history of the patient, adequate time to evaluate the patient, and complete information of symptoms and medications.

How do I know I have ALS?

Some of the earliest and most common signs of ALS are: Difficulty walking or doing normal, day-to-day activities. Muscle twitching in the arms, shoulders, legs or tongue (also known as fasciculations) Muscle cramps, especially in the hands and feet.

How did your ALS symptoms start?

Initial Symptoms of ALS

About 25% of those eventually diagnosed with ALS have bulbar onset which strikes the brainstem's corticobulbar area. This section controls muscles in the face, neck and head. Bulbar onset usually affects voice and swallowing first. The majority of ALS patients have limb onset.

What does ALS in legs feel like?

Early symptoms of ALS are usually characterized by muscle weakness, tightness (spasticity), cramping, or twitching (fasciculations). This stage is also associated with muscle loss or atrophy.

Is dizziness a symptom of ALS?

Are you experiencing occasional bouts of dizziness? No, it's not a new symptom of ALS (or aging!). Your dizziness is most likely a result of your new normal life with ALS – – a life with a lot more sitting and a lot less head movement.

Can heavy metals cause ALS?

Heavy metals, such as lead, mercury, and selenium, have been epidemiologically linked with a risk of ALS, but a molecular mechanism proving the connection has not been shown.

What is the new ALS drug?

Exactly one week after the aducanumab decision was made public, Amylyx, a pharmaceutical company based in Cambridge, Mass., filed a new drug submission to Health Canada for AMX0035, its promising treatment for ALS. Amylyx is also working on an expedited pathway with the European Medicines Agency.

Does exercising help with ALS?

Exercise may have many benefits for ALS patients, including reducing depression and improving strength and stamina. But it must be performed carefully to be beneficial.
