ALS is a motor neuron disease, which is a group of neurological disorders that selectively affect motor neurons, the cells that control voluntary muscles of the body. [3] Other motor neuron diseases include primary lateral sclerosis (PLS), progressive muscular atrophy (PMA), progressive bulbar palsy , pseudobulbar palsy , and monomelic ...
A score of 0 on a question would indicate no function while a score of 4 would indicate full function. [4] [5] This scale has been useful for doctors in diagnosing patients, measuring disease progression and also for researchers when selecting patients for a study and measuring the potential effects of a clinical trial. [4] [6]
Those that affect children tend to be inherited or familial, and their symptoms are either present at birth or appear before learning to walk. Those that affect adults tend to appear after age 40. [2] The clinical course depends on the specific disease, but most progress or worsen over the course of months. [6]
[4] [5] ALS has an oligogenic mode of inheritance, meaning that mutations in two or more genes are required to cause disease. [6] C9orf72 is the most common gene associated with ALS, causing 40% of familial cases of ALS, as well as a small percentage of sporadic cases; [7] it also causes about 25% of familial cases of frontotemporal dementia.

PEORIA, Ill. (WYZZ) — ALS, otherwise known as Lou Gehrig’s disease, affects about 30,000 people in the United States. According to the Mayo Clinic, Amyotrophic lateral sclerosis (ALS) affects ...
PMA affects only the lower motor neurons, in contrast to amyotrophic lateral sclerosis (ALS), the most common MND, which affects both the upper and lower motor neurons, or primary lateral sclerosis, another MND, which affects only the upper motor neurons. The distinction is important because PMA is associated with a better prognosis than ALS.
A study introduced the SOD1/GFP transgenic zebra-fish to study that specific gene on the development and occurrence of ALS in the fish, and how can that be used in testing potential therapeutic molecules. [7] All the previous models are considered simple, and save time and money due to their short lifespan and small and simple body structure. [4]
Multifocal motor neuropathy (MMN) is a progressively worsening condition where muscles in the extremities gradually weaken.The disorder, a pure motor neuropathy syndrome, is sometimes mistaken for amyotrophic lateral sclerosis (ALS) because of the similarity in the clinical picture, especially if muscle fasciculations are present.
