Motor neuron disease
|Motor neuron disease|
|Synonyms||motor neurone disease|
Motor neuron diseases include:
- Amyotrophic lateral sclerosis (ALS)
- Hereditary spastic paraplegia (HSP)
- Primary lateral sclerosis (PLS)
- Progressive muscular atrophy (PMA)
- Progressive bulbar palsy (PBP)
- Pseudobulbar palsy
The different classes of spinal muscular atrophy (SMA) are sometimes included in the group by some neurologists; however spinal muscular atrophies are distinct diseases with clear genetic causes.
In the United States, the term is often used to denote ALS, the most common disorder in the group. In the United Kingdom, the term is spelled motor neurone disease and is sometimes used for the entire group, but can also refer specifically to ALS.
While MND refers to a specific subset of similar diseases, there are numerous other diseases of motor neurons that are referred to collectively as "motor neuron disorders", for instance disease belonging to spinal muscular atrophies. However, they are not classified as "motor neuron diseases" by the tenth International Statistical Classification of Diseases and Related Health Problems (ICD-10), which is the definition followed in this article.
