The exact cause of MND is not known. You can’t catch MND from somebody. Generally, MND is believed to be caused because of a combination of environmental, lifestyle and genetic factors. Most cases of MND occur spontaneously without any identifiable cause.
What is MND and what causes it?
MND symptoms. MND usually starts slowly, sometimes starting on one side of the body and then spreading. Usually, the first things people notice are: weakness in the hands and grip. slurred speech. weakness in the legs, and a tendency to trip. weakness of the shoulder, making lifting difficult.
What are the signs and symptoms of MND?
The long-term outlook depends on the type. Motor neurons instruct the muscles to move by passing on signals from the brain. They play a role in both conscious and automatic movements, such as swallowing and breathing. Experts believe that around 10% of MNDs are hereditary.
What is the long-term outlook for motor neuron disease (MND)?
It affects more males than females. The most common type of MND is amyotrophic lateral sclerosis (ALS). The renowned English physicist Stephen Hawking lived with ALS for many decades until his death in March 2018. The American baseball player, Lou Gehrig, also had ALS.

What type of disease is motor neurone disease?
“Motor neuron disease” refers to a group of diseases that cause the motor nerves in the spine and brain to lose function over time. They are a rare but severe form of neurodegenerative disease. Motor neurons are nerve cells that send electrical output signals to the muscles, affecting the muscles' ability to function.
What is the most significant symptom of neuromuscular disorders?
Neuromuscular disorders include a wide-range of diseases affecting the peripheral nervous system, which consists of all the motor and sensory nerves that connect the brain and spinal cord to the rest of the body. Progressive muscle weakness is the predominant condition of these disorders.

Is it accurate to classify ALS as a neuromuscular disorder?
ALS has traditionally been classified within the domain of neuromuscular diseases, which are a unique spectrum of disorders that predominantly affect the peripheral nervous system. However, over the past decades compounding evidence has emerged that there is extensive involvement of the central nervous system.
Are ALS and MND the same?
Some of the most common MNDs include: Amyotrophic lateral sclerosis (ALS), also called classical motor neuron disease, affects both the upper and lower motor neurons. It causes rapid loss of muscle control and eventual paralysis. Many doctors use the term motor neuron disease and ALS interchangeably.
What is the difference between motor neuron disease and muscular dystrophy?
MS is a scarring and hardening of the sheath around the nerves in the brain, spinal cord, and optic nerve. MD is a muscular disorder with specific kinds of MD involving different muscles in the body. MD is almost exclusively hereditary. MS is sporadic with some familial tendency.

Your doctor may refer you to a neurologist who will examine you and do various tests. These may include: blood tests.
How many cases of MND are familial?
Around 1 in 10 cases are ‘familial’ (meaning the condition is inherited) due to a genetic mutation (or error in the gene). If a person has an MND-related genetic mutation, their children have a 50/50 chance of inheriting the MND-related genetic mutation.
What is the name of the disease that affects the motor nerves?
Motor neurone disease (MND) is the name for a group of diseases that affects particular nerves known as motor nerves, or motor neurons. In MND, those neurons generate and die and slowly the muscles become weaker. This eventually leads to paralysis. It is also known as Lou Gehrig's disease, amyotrophic lateral sclerosis or ALS.
How long does it take to die from MND?
Most people with MND die within 2 to 3 years of developing the condition, however some people can live a long time.
Can you get MND if you have a genetic mutation?
If a person in your family has MND, other people in the family can be tested to see if they have the genetic mutation. People who inherit the genetic mutation have a high chance of developing MND, but not all people with the genetic mutation will develop MND.
What are the two types of motor neurons?
They are a type of nerve cell, and their job is to send messages around your body so you can move. You have two main kinds: 1 Upper motor neurons are in your brain. They send messages from there to your spinal cord. 2 Lower motor neurons are in your spinal cord. They transmit the messages sent from your brain to your muscles.
Where are the motor neurons located?
Upper motor neurons are in your brain. They send messages from there to your spinal cord. Lower motor neurons are in your spinal cord. They transmit the messages sent from your brain to your muscles. As nerve cells die when you have a motor neuron disease, electrical messages can't get from your brain to your muscles.
