A cholinergic crisis is an over-stimulation at a neuromuscular junction due to an excess of acetylcholine (ACh), [1] as a result of the inactivity of the AChE enzyme, which normally breaks down acetylcholine.
Congenital myasthenic syndrome (CMS) is an inherited neuromuscular disorder caused by defects of several types at the neuromuscular junction. The effects of the disease are similar to Lambert-Eaton Syndrome and myasthenia gravis, the difference being that CMS is not an autoimmune disorder. There are only 600 known family cases of this disorder ...
Acquired myasthenia gravis is the most common neuromuscular junction disease.(reference 7) Important observations were made by Patrick and Lindstrom in 1973 when they found that antibodies attacking the acetylcholine receptors were present in around 85% of cases of myasthenia gravis.(reference renamed form 13)(reference 36) The remaining ...
It is also known as myasthenic syndrome, Eaton–Lambert syndrome, and when related to cancer, carcinomatous myopathy. [2] Around 60% of those with LEMS have an underlying malignancy, most commonly small-cell lung cancer; it is therefore regarded as a paraneoplastic syndrome (a condition that arises as a result of cancer elsewhere in the body). [3]
Acetylcholine Acetylcholinesterase Acetylcholinesterase inhibition. Acetylcholinesterase inhibitors (AChEIs) also often called cholinesterase inhibitors, [1] inhibit the enzyme acetylcholinesterase from breaking down the neurotransmitter acetylcholine into choline and acetate, [2] thereby increasing both the level and duration of action of acetylcholine in the central nervous system, autonomic ...
Lambert–Eaton myasthenic syndrome (LEMS) is an autoimmune condition that attacks the neuromuscular junction, either as a paraneoplastic syndrome (typically older patients) or associated with a non-cancerous primary autoimmune condition (typically younger patients). It usually involves lower limb weakness and exercise-induced fatiguability ...

Paraneoplastic syndrome, Guillain-Barré syndrome, diabetes, amyloidosis, Sjogren's syndrome, and Morvan syndrome. Autoimmune autonomic ganglionopathy is a type of immune-mediated autonomic failure that is associated with antibodies against the ganglionic nicotinic acetylcholine receptor present in sympathetic , parasympathetic , and enteric ...
