There a few diseases that mimic ALS pretty good: 1) Multifocal motoric neuropathy (MMN) - weakness, fasciculations (not too much) but NO atrophy and very slow progression. 2)Postpoliomyelitic syndrome - Late consequences of poliomyelitis. Weakness, fasciculations, tireness. 3) Myasthenia gravis -no need to comment.
ALS is a progressive, degenerative disease of the nervous system. It is one of a group of diseases, called motor neuron diseases (MND), in which specialized nerve cells that control movement of the voluntary muscles gradually cease functioning and die. Fasciculation is a sign of muscle irritability, as the normal action of the lower motor neuron on the muscle is impaired. 2  The sole involvement of lower motor neurons can be seen in a form of ALS called progressive muscular atrophy.
