- A brief description of the symptoms of some of the more common MNDs follows. Amyotrophic lateral sclerosis (ALS), also called Lou Gehrig's disease or classical motor neuron disease, is a progressive, ultimately fatal disorder that disrupts signals to all voluntary muscles.pinal muscular atrophy (SMA) is a hereditary disease affecting the lower motor neurons. It is an autosomal recessive disorder caused by defects in the gene SMN1, which makes a protein that is important for the survival of motor neurons (SMN protein).

- While ALS is the most common motor neuron disease, we also treat all other forms, including: 1  PLS (Primary Lateral Sclerosis), affecting the upper motor neurons in the brain and spinal cord. 2  PMA (Primary Muscular Atrophy), affecting the lower motor neurons from the spine to the muscle.

- Motor neuron disease (MND) is a serious and incurable form of progressive neurodegeneration-over time the nerves in the spine and brain progressively lose function. In the case of motor neuron disease, motor neurons-types of nerve cells-are affected.

- Mutations in the SMN1 gene cause spinal muscular atrophy types I, II, III, and IV. SMN1 gene mutations lead to a shortage of the SMN protein. Without SMN protein, motor neurons die, and nerve impulses are not passed between the brain and muscles.

- Background. 1  The childhood neuromuscular disease spinal muscular atrophy (SMA) is caused by mutations or deletions of the survival motor neuron (SMN1) gene. Although SMA has traditionally been considered a motor neuron disease, the muscle-specific requirement for SMN has never been fully defined.

Multiple sclerosis (MS) - common problems Motor neurone disease (MND) is also called amyotrophic lateral sclerosis (ALS) and Lou Gehrig's disease. MND is a rapidly progressing, neurological disease. Motor neurones are nerve cells that control the voluntary muscles of the trunk and limbs, and affect speech, swallowing and breathing. Damage to these nerves causes muscle weakness and wasting.

- Researchers still don't know exactly what causes motor neurons to die with ALS. Gene changes, or mutations, are behind 5% to 10% of ALS cases. More than 12 different gene changes have been linked to ALS. One change is to a gene that makes a protein called SOD1.

What Are Motor Neuron Diseases? It’s one kind of motor neuron disease (MND), and there are several other lesser-known types. What Are Motor Neurons? They are a type of nerve cell, and their job is to send messages around your body so you can move.

Demyelinating disease A demyelinating disease is any disease of the nervous system in which the myelin sheath of neurons is damaged. This damage impairs the conduction of signals in the affected nerves. In turn, the reduction in conduction ability causes deficiency in sensation, movement, cognition, or other functions depending on which nerves are involved. Some demyelinating diseases are caused by genetics, some by infectious agents, some by autoimmune reactions, and some by unknown factors. Organophosphates, a clas

- Over time, Lou Gehrig's disease causes these motor neurons in the brain and spinal cord to shrink and disappear, so that the muscles no longer receive signals to move. As a result, the muscles become smaller and weaker. Gradually the body becomes paralyzed, which means that the muscles no longer work.

Why Does ALS Spread? Lou Gehrig's disease damages motor neurons in the brain and spinal cord. Motor neurons are nerve cells that control muscle movement. Upper motor neurons send messages from the brain to the spinal cord, and lower motor neurons send messages from the spinal cord to the muscles.

- Causes of motor neurone disease. Motor neurone disease occurs when specialist nerve cells (motor neurones) in the brain and spinal cord progressively lose their function.It's not clear why this happens. In most cases, a person with motor neurone disease won't have a family history of the condition. This is known as sporadic motor neurone disease.ossible causes of motor neurone disease. It's still unclear why the motor neurones begin to lose function. Most experts believe that it's a combination of interrelated factors that ultimately affect either the motor neurones or the nerve cells that support them.

Amyotrophic lateral sclerosis Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease and motor neurone disease (MND), is a specific disease that causes the death of neurons which control voluntary muscles. Some also use the term motor neuron disease for a group of conditions of which ALS is the most common. ALS is characterized by stiff muscles, muscle twitching, and gradually worsening weakness due to muscles decreasing in size. This results in difficulty in speaking, swallowing, and eventually breathing. The cause is not known in 90% to 95% of cases. About 5–10% of cases are inherited from a person's parents.
