How do people get 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 amyotrophic lateral sclerosis in simple terms?
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.
Why is it called amyotrophic lateral sclerosis?
The word “amyotrophic” comes from Greek roots that mean “without nourishment to muscles” and refers to the loss of signals nerve cells normally send to muscle cells. “Lateral” means “to the side” and refers to the location of the damage in the spinal cord.
Is ALS 100% fatal?
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.
Can ALS be cured?
Currently there is no cure for ALS, yet patients suffering from the disease can be made more comfortable with the following options: medications to relieve painful muscle cramps, excessive salivation and other symptoms. heat or whirlpool therapy to relieve muscle cramping.
What is the difference between ALS and Parkinson’s?
Parkinson’s disease (PD) is a movement disorder that afflicts over one million in the U.S.; amyotrophic lateral sclerosis (ALS or Lou Gehrig’s disease) is less prevalent but also has a high incidence.
What is the difference between primary lateral sclerosis and ALS?
Both conditions are motor neuron diseases, although degeneration in primary lateral sclerosis (PLS) is of only the UMN whereas in ALS it is of both the UMN and LMN. Muscle wasting, Charley Horse cramps, and significant weakness seen in ALS is the result of LMN degeneration.
What is the life expectancy of a person with ALS?
Although the mean survival time with ALS is two to five years, some people live five years, 10 years or even longer. Symptoms can begin in the muscles that control speech and swallowing or in the hands, arms, legs or feet.
What is the difference between MS and ALS?
MS is an autoimmune disease that causes your body to attack itself. ALS, also called Lou Gehrig’s disease, is a nervous system disorder that wears away nerve cells in your brain and spinal cord.
Is ALS a death sentence?
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.)
What is amyotrophic lateral sclerosis (ALS)?
Amyotrophic lateral sclerosis (ALS) is a rare neurological disease that primarily affects the nerve cells (neurons) responsible for controlling voluntary muscle movement (those muscles we choose to move). Voluntary muscles produce movements like chewing, walking, and talking. The disease is progressive, meaning the symptoms get worse over time.
What is primary lateral sclerosis?
Primary lateral sclerosis is a type of motor neuron disease that causes muscle nerve cells to slowly break down, causing weakness.
What are the symptoms of amyotrophic lateral sclerosis?
The onset of ALS can be so subtle that the symptoms are overlooked but gradually these symptoms develop into more obvious weakness or atrophy. The first sign of ALS usually appears in the hand or arm and can show as difficulty with simple tasks such as buttoning a shirt, writing, or turning a key in a lock.
Is amyotrophic lateral sclerosis inherited?
Some cases are inherited. ALS often begins with muscle twitching and weakness in a limb, or slurred speech. Eventually, ALS affects control of the muscles needed to move, speak, eat and breathe. There is no cure for this fatal disease. Signs and symptoms of ALS vary greatly from person to person, depending on which neurons are affected.
