Multifocal motor neuropathy is an acquired immune-mediated demyelinating neuropathy that is characterised by slowly progressive weakness, cramping and fasciculations and lack of significant sensory involvement. It may clinically look similar to amyotrophic lateral sclerosis that has predominant lower motor neuron involvement, though it lacks muscle atrophy and rapid progression.
No one really knows what causes multifocal motor neuropathy, though scientists do know that it is an autoimmune disease, implying that the immune system tends to mistakenly attack the nerve assuming them to be invaders. The researchers are currently studying the disease to try and find out why it really happens.
Multifocal motor neuropathy is not a life-threatening medical condition and in most cases, you can easily seek treatment to make the muscles stronger. The disease tends to get worse slowly and after some time you may find it hard to perform the daily tasks such as typing or getting dressed. For most people, the symptoms are so mild that they do not really need treatment.
