Which medical conditions can cause myasthenia gravis?
GaleEncyofNeuroDis
10 percent of patients have a tumor in the thymus, that is usually benign, and 70% have changes that indicate an active immune response.

What is the reason for an enlarged thymus gland?
Myasthenia gravis is one cause
Is myasthenia gravis a group of inherited muscle disorders that cause muscle weakness without affecting the nervous system?
Myasthenia gravis is a neuromuscular disorder involving the muscles and the nerves that control them.
Does polyvinyl chloride cause myasthenia gravis?
Although polyvinyl chloride (PVC) is associated with some health effects, through Phthalates, they are usually either breast cancer and endocrine disruptions. Myasthenia Gravis is when the neurotransmitter acetylcholine is blocked in the eye, causing eye muscles to become relaxed and either partially or completely uncontrollable. It is unlikely that PVC cause myasthenia gravis.
A deficiency of ACh receptors in a motor end plate would cause and is called?
myasthenia gravis
What is a chronic autoimmune disorder in which the motor neurons fail to transmit impulses to the muscles to cause muscle contractions?
A chronic autoimmune disease that affects the neuromuscular junction is myasthenia gravis. It leads to fluctuating muscle weakness and fatigue.
Why aminoglycosides cause weakness in myasthenia gravis?
Aminoglycosides inhibit the release of acetylcholine from the motor nerve. Myestenia gravis patients are more susceptible to this effect. So these drugs are to be avoided in myestenia gravis patients.
What is the mortality rate due to respiratory failure associated with myasthenia gravis?
In a few cases, the severe weakness of MG may cause respiratory failure, which requires immediate emergency medical care. Advances in medical care have reduced the mortality rate to about 3%.
Can Myasthenia Gravis kill you?
no, not unless something happens because of it ex respiratory failure.
What is a disease that can affect the thymus gland?
Scientists beleive that disorder of thymus gland can cause Myasthenia Gravis , a disease of severe muscle weakness . In this antibodies are produced against Ach receptors of neuro-muscular junction .
What can be the cause of new onset palsies in adults?
New onset palsies in adults can stem from myasthenia gravis, diabetes, meningitis, microvascular disease (atherosclerotic vascular disease) or giant cell arteritis (arterial inflammation).
Is myasthenia gravis caused by herpes?
Myasthenia Gravis is an autoimmune disease of the neuromuscular system that is characterized by high plasma levels of acetylcholine receptor (AChR) antibodies, which invoke an immune response against these receptors. Production of these antibodies are caused by molecular mimicry of a self antigen. T-helper cells, a type of immune system cells, can come across antigen presenting cells that display an antigen that is similar, in sequence, to AChR's. The T-helper cells are activated in this manner and can cause an immune response (antibody production) against AChR's. In essence, the Herpes virus is known to have a similar sequence to AChR's, therefore, the existance of the Herpes virus increases the risk of Myasthenia Gravis development.
Is myasthenia gravis related to Grave?
Both myasthenia gravis (MG) and Graves disease (GD) are autoimmune diseases. Myasthenia gravis is characterized by impaired transmission of the neural stimuli to the muscles due to circulating antibodies anti-acetylcholine receptor. Graves disease is autoimmune hyperthyroidism due to antibodies anti-TSH (Thyroid Stimulating Hormone) receptor. The prevalence of auoimmune thyroid diseases in MG is about 5-10%. The incidence of MG in GD is fairly low: aprox 0,2%. One problem is the overlapping of the symptoms which may cause diagnostic confusion. Not only clinical manifestation but also some morphological aspects, like thymus hyperplasia confirmed by thoracic CT are shared by the 2 diseases. Generally, only mild forms of MG (especially ocualr form) are associateed with GD. When in fact it was a myasthenia-like syndrome as a manifestation of GD remission of GD will cure MG-like symptoms also.
