What is affected in myasthenia gravis?

Answer 1

It is an autoimmune neuromuscular disease, characterized by muscle weakness and fatiguability. Where antibodies are directed against the muscle's own acetylcholine receptors that stimulates its contraction. Leading to increasing weakness of the body muscles during periods of activity; since the muscle contracts less at every stimulus.

MG is a chronic autoimmune neuromuscular disease characterized by degrees of weakness of the skeletal muscles of the body which increases during periods of activity and improves after periods of rest.

I believe that my exposure to agent orange in Vietnam in 1968-1969 caused my myasthenia gravis...I am trying to find some supporting information on this...My e-mail address is egreene42@AOL.com .thanks for your help...

Answer 3

Initial symptoms of MG may include difficulty speaking (dysarthria), difficulty swallowing (dysphagia), drooping eyelids (ptosis), and double vision (diplopia). Patients often have nasal-sounding speech and weak neck muscles that give the head a tendency to fall forward or backward.These symptoms occur in about 90% of MG cases, are usually intermittent (i.e., come and go), and may disappear for weeks and then recur.

Generalized weakness often develops in the trunk, arms, and legs within a year of onset. Arm muscles usually are affected most severely. Muscle weakness tends to worsen as the day progresses, especially after prolonged activity.

Pregnancy can improve, worsen, or have little effect on MG symptoms. Frequently, symptoms first occur during pregnancy or after delivery.

Answer 4

affects the neuromuscular junction, interrupting the communication between nerve and muscle, and thereby causing weakness. A person with MG may have difficulty moving their eyes, walking, speaking clearly, swallowing

Answer 5

Myasthenia gravis can be classified according to which skeletal muscles are affected.

Answer 6

Neuromuscular junction
