Neuromuscular junction diseases can also be referred to as end plate diseases or disorders. [citation needed] Among neuromuscular diseases some can be autoimmune disease, or hereditary disorders. They can affect either presynaptic mechanisms or postsynaptic mechanisms, preventing the junction from functioning normally.
Limb girdle muscular dystrophies (LGMD) as defined by the European Neuromuscular Centre in 2018. [1] [2] They are named by the following system: LGMD, recessive or dominant inheritance (R or D), order of discovery (number), affected protein.
A neuromuscular disease is any disease affecting the peripheral nervous system (PNS), [a] the neuromuscular junctions, or skeletal muscles, all of which are components of the motor unit. [4] Damage to any of these structures can cause muscle atrophy and weakness. Issues with sensation can also occur. Neuromuscular diseases can be acquired or ...
Any disorder that compromises the synaptic transmission between a motor neuron and a muscle cell is categorized under the umbrella term of neuromuscular diseases. These disorders can be inherited or acquired and can vary in their severity and mortality. In general, most of these disorders tend to be caused by mutations or autoimmune disorders.
[4] [3] On single-fiber examination, features may include increased jitter (seen in other diseases of neuromuscular transmission) and blocking. [4] Blood tests may be performed to exclude other causes of muscle disease (elevated creatine kinase may indicate a myositis, and abnormal thyroid function tests may indicate thyrotoxic myopathy).
Muscular dystrophies (MD) are a genetically and clinically heterogeneous group of rare neuromuscular diseases that cause progressive weakness and breakdown of skeletal muscles over time. [1] The disorders differ as to which muscles are primarily affected, the degree of weakness, how fast they worsen, and when symptoms begin. [1]
Neuromuscular medicine is a subspecialty of neurology and physiatry that focuses the diagnosis and management of neuromuscular diseases.The field encompasses issues related to both diagnosis and management of these conditions, including rehabilitation interventions to optimize the quality of life of individuals with these conditions.

Hereditary motor and sensory neuropathy are relatively common and are often inherited with other neuromuscular conditions, and these comorbidities cause an accelerated progression of the disease. [citation needed] Most forms of HMSN affect males earlier and more severely than females, but others show no predilection to either sex.
