Neuromyotonia (NMT), also known as Isaacs' syndrome, is a form of peripheral nerve hyperexcitability that causes spontaneous muscular activity resulting from repetitive motor unit action potentials of peripheral origin.
The three causes of NMT are: 1) Acquired 2) Paraneoplastic 3) Hereditary
The acquired form is the most common accounting for up to 80 percent of all cases and is suspected to be autoimmune mediated, which is usually caused by anti...

Neuromyotonia (NMT), also known as Isaacs' syndrome, is a form of peripheral nerve hyperexcitability that causes spontaneous muscular activity resulting from repetitive motor unit action potentials of peripheral origin.
The three causes of NMT are: 1) Acquired 2) Paraneoplastic 3) Hereditary
The acquired form is the most common accounting for up to 80 percent of all cases and is suspected to be autoimmune mediated, which is usually caused by antibodies against neuromuscular junction.
The exact cause is unknown. However, autoreactive antibodies can be detected in a variety of peripheral (e.g. myasthenia gravis, Lambert-Eaton myasthenic syndrome) and central nervous system (e.g. paraneoplastic cerebellar degeneration, paraneoplastic limbic encephalitis) disorders. Their causative role has been established in some of these diseases but not all. Neuromyotonia is considered to be one of these with accumulating evidence for autoimmune origin over the last few years. Autoimmune neuromyotonia...
