ALS is a motor neuron disease, which is a group of neurological disordersthat selectively affect motor neurons, the cells that control voluntary musclesof the body.[3] Other motor neuron diseases include primary lateral sclerosis(PLS), progressive muscular atrophy(PMA), progressive bulbar palsy, pseudobulbar palsy, and monomelic amyotrophy(MMA).
A fasciculation, or muscle twitch, is a spontaneous, involuntary muscle contraction and relaxation, involving fine muscle fibers. [1] They are common, with as many as 70% of people experiencing them. [1] They can be benign, or associated with more serious conditions. [1] When no cause or pathology is identified, they are diagnosed as benign ...
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.
Fasciculations can be caused [4] or worsened by intense and long periods of daily exercise. [2] BFS can also be caused by long-term use of anticholinergics, [4] and fasciculations may be caused by other drug use or exposure to steroids, nicotine, caffeine, alcohol, insecticides and pesticides. [2] Thyroid disease may also cause similar symptoms ...
However, fasciculations are rarely the first sign of ALS as the hallmark sign is weakness. [9] Similarly, multiple sclerosis has been the initial misdiagnosis in some NMT patients. In order to get an accurate diagnosis see a trained neuromuscular specialist. People diagnosed with benign fasciculation syndrome or enhanced physiological tremor ...

Progressive muscular atrophy (PMA), also called Duchenne–Aran disease and Duchenne–Aran muscular atrophy, is a disorder characterised by the degeneration of lower motor neurons, resulting in generalised, progressive loss of muscle function. PMA is classified among motor neuron diseases (MND) where it is thought to account for around 4% of ...
Glutamate released from the upper motor neurons triggers depolarization in the lower motor neurons in the anterior grey column, which in turn causes an action potential to propagate the length of the axon to the neuromuscular junction where acetylcholine is released to carry the signal across the synaptic cleft to the postsynaptic receptors of the muscle cell membrane, signaling the muscle to ...
